About the Car

2018 Acura TLX

The refreshed 2018 Acura TLX performance luxury sedan launches with a more sporty and alluring look reflecting the brand’s new design direction, along with an all-new TLX A-Spec variant for V6 powered models, and new premium features. The 2018 TLX offers AcuraWatch™ as standard equipment on all grades, leading all luxury midsize sedans in the application of advanced safety and driver-assistive technologies.

The 2018 Acura TLX also is the first Acura to feature a redesigned dual-screen user interface (ODMD 2.0) with more intuitive menus and command structures complemented by a new 7-inch capacitive touchscreen (previously resistive type) with a 30-percent faster response time and Android Auto™ and Apple CarPlay™ compatibility.

The 2018 TLX is the second model in the Acura lineup (following the 2017 MDX) to take design cues from the Acura Precision Concept and boasts an alluring new style, highlighted by the Acura diamond pentagon grille and amplified by its more sharply sculpted hood and front fenders, paired with strong dynamic characteristics including more aggressive and sporty front and rear fascia, side sills, and available dual rear exhaust finishers and rear diffuser. Acura’s signature 5-lamp Jewel Eye™ LED headlights and new alloy wheel designs complete the distinctive, athletic and aggressive character of the 2018 TLX.

New Features for TLX V6 Models

Acura TLX V6 models feature a new rear diffuser with exposed dual-exhaust while the Technology Package adds a chrome side sill garnish, new leather seats with high-contrast stitching and piping, and power-operated driver’s seat thigh extension.

The Acura TLX V6 Advance Package gains new, premium features including trapezoidal fog lights and rear exhaust ports, a Surround View camera system, built-in wireless charging, white LED ambient interior light piping, a heated steering wheel and heated rear (outboard) seats, power-folding side mirrors, and a new body-colored decklid spoiler.

All-New Acura TLX V6 A-Spec

Reflecting Acura’s Precision Crafted Performance DNA, the all-new 2018 TLX A-Spec, available on both front-wheel drive and SH-AWD™ variants of the V6-powered TLX, amps up the sporty character of TLX and features exclusive design elements inside and out, along with key enhancements to chassis tuning and wheel/tire specification.

The Acura TLX A-Spec’s unique styling begins in front with a matte-black diamond pentagon grille with dark chrome surround, an aggressive lower front fascia with broad center air opening flanked by round LED fog lights, and a dark appearance for the Jewel Eye LED headlights. A-Spec exclusive 19-inch alloy wheels finished in Shark Gray paint are shod with 245-series tires and combine with aggressively flared side sills for a more athletic and planted stance. The A-Spec exterior upgrades continue at the rear with a gloss-black decklid spoiler, “smoked” LED taillights, and an exclusive fascia featuring a lower diffuser accented by 4-inch round dual exhaust finishers. A matte-black side window surround and A-Spec badging on the front fenders and rear decklid completes the look.

Inside, the TLX V6 A-Spec features more aggressively bolstered front seats, an A-Spec-badged thick-rimmed steering wheel, red driver’s meter highlights, black headliner and pillar treatment, brushed aluminum-look interior trim, stainless steel driver’s footrest, and front and rear door sill trim.

In addition to the improved lateral grip and responsiveness offered by Michelin Primacy 245/40R19 tires (compared to 225/50R18 on other V6 models), the TLX V6 A-Spec benefits from a retuned electric power steering system and damper settings. Models with SH-AWD also get a quicker steering ratio for increased response and a stiffer spring rate and rear stabilizer bar for improved body control.

The TLX V6 A-Spec is available in five exterior colors, including a trim-exclusive Still Night Blue Pearl, and one of two unique interior color schemes, Black with Alcantara™ seat and door inserts or Full Red which features a bold red leather throughout. A-Spec models have the same feature set as the TLX V6 with Technology Package as well ventilated front seats, wireless charging pad and LED ambient light piping found in the Advance Package.

Powertrain and Chassis

The 2018 Acura TLX continues to be offered with two advanced powertrains: a 2.4-liter, 206-horsepower i-VTEC inline-4 mated to an 8-speed Dual Clutch Transmission (8DCT) with torque converter; and a 3.5-liter, 290-horsepower i-VTEC V6 mated to a 9-speed automatic transmission, which for 2018 has been retuned for a more refined feel.

Two-wheel drive variants of the 2018 TLX, with either the 2.4-liter or 3.5-liter engines, come equipped with Acura Precision All-Wheel Steer™ (P-AWS™), with independent left and right rear-wheel toe angle control to enhance overall handling precision, low-speed maneuverability and high-speed stability.

Acura Super-Handling All Wheel Drive™ (SH-AWD®), the most sophisticated torque-vectoring AWD system in the industry, is available for the first time on all V6-powered variants (previously available with Technology or Advance Package only). SH-AWD elevates the TLX driving experience to a new level, enhancing cornering grip, power delivery and all-weather handling and control through dynamic distribution of engine torque to all four wheels and independent control of torque delivery to the left and right rear wheels.

Acura TLX 2.4-liter models can be upgraded with the Technology Package, and 3.5-liter models can be upgraded with either Technology, A-Spec or Advance Packages.


As Acura’s top selling car, the 2018 TLX performance luxury sedan offers a range of power and drivetrain choices, with two direct-injected engines, two advanced transmissions and, in V6 powered models, available Super Handling All-Wheel Drive™ (SH-AWD®).

The Acura TLX’s two direct injected (DI) engines combine power and efficiency. The 2.4-liter DOHC i-VTEC® 4-cylinder produces a peak 206 horsepower and 182 lb.-ft. of torque. The available 3.5-liter direct injected i-VTEC® 24-valve V6 produces a peak 290 horsepower and 267 lb.-ft. of torque. To boost fuel efficiency, Variable Cylinder Management (VCM) automatically deactivates three of the engine’s six cylinders under light engine loads. TLX SH-AWD models also add an automatic idle-stop feature to further improve fuel efficiency.

To make the most of these powerful and refined engines, the TLX features two highly advanced transmissions. 2.4-liter TLX models have an 8-Speed Dual-Clutch Transmission (8DCT), the world’s first automotive DCT with a torque converter, featuring Sequential SportShift. With its closely-spaced ratios, ultra-quick shifts and automatic downshift rev-matching, the 8DCT gives the 2.4-liter TLX an aggressively sporting feel. The torque converter provides exceptionally smooth operation in stop-and-go situations, plus it offers off-the-line torque multiplication for substantially improved initial acceleration that a DCT alone cannot equal. For 2018, the 8DCT has been updated for smoother operation.

TLX models with the 3.5-liter V6 are equipped with a 9-speed automatic transmission featuring Sequential SportShift. Retuned for 2018 for a more refined feel, the transmission is engineered to handle the V6 engine’s substantial power output, and its closely spaced gear ratios enhance both performance and fuel efficiency.

Acura’s acclaimed torque vectoring Super Handling All-Wheel Drive™ (SH-AWD®), the most sophisticated all-wheel drive system in the industry, is available exclusively with the 3.5-liter V6. SH-AWD progressively distributes torque not only between the front and rear axles, but also between the left and right rear wheels. Using torque vectoring to help turn the vehicle, SH-AWD creates a more responsive, neutral and predictable platform while providing outstanding all-weather confidence and control.

All Acura TLX front-wheel drive models feature standard Acura Precision All-Wheel Steer™ (P-AWS), which is designed to help give the TLX greater agility and handling balance.

Direct-Injected 2.4-liter Inline 4-cylinder Engine

The TLX’s direct injected (DI) 2.4-liter DOHC i-VTEC® 4-cylinder engine features a host of intelligent technology. The engine’s i-VTEC system combines VTC (Variable Timing Control), which continuously adjusts the intake camshaft phase, with Variable Valve Timing and Lift Electronic Control (VTEC), which changes valve lift, timing and duration of the intake valves. The direct injection (DI) system, dual-stage intake manifold and other technologies combine to produce 206 horsepower and 182 lb.-ft. of torque. The 4-cylinder engine meets ULEV-3 emissions standards in select states, and Federal Tier 2, Bin 5 standards.

4-Cylinder Engine Block, Crankshaft and Pistons

The Acura TLX’s 2.4-liter engine has a lightweight die-cast aluminum block with a single main-bearing cradle design that creates a rigid assembly to help minimize noise and vibration. Cast-in iron cylinder liners provide long-lasting durability. Each journal on the forged-steel crankshaft is micropolished to reduce internal friction. To improve smoothness throughout the rpm range and help lower noise levels, the engine is fitted with an internal balancer unit. Consisting of a pair of chain-driven counter-rotating shafts located in the lower block and integrated into the oil pan, the balancing system helps quell the inherent second-order harmonic vibrations that normally impact inline 4-cylinder engines.

To reduce piston-sliding friction, the cylinder bores are offset by 8.0 mm from the crankshaft. This gives the connecting rods a more favorable angle during each power stroke, which reduces side loading on the pistons and in turn, improves efficiency. The engine features a forged crankshaft for high rigidity and low friction. Lightweight pistons have a carefully optimized skirt design to minimize reciprocating weight, and reduced weight minimizes vibration and increases operating efficiency. The piston crowns are dished, to help maintain stable combustion and to optimize distribution of the stratified fuel charge from the direct injector in each cylinder. This close control over the combustion process boosts overall operating efficiency.

4-Cylinder Dual-Stage Intake Manifold

To maximize power output, the 2.4-liter engine has a dual-stage intake manifold has two different intake runner lengths that are selected based on the operating conditions. An actuator and a set of four butterfly valves control the intake runner switching process. At low engine speeds, the long runners are used to improve low-end torque. At higher engine speeds the system switches to the short intake runners for greater high rpm power. The result is intake tuning that is optimized for the engine’s entire operating range.

2.4-liter Engine Cylinder Head and Valvetrain

The lightweight cylinder head is made of pressure-cast aluminum alloy, with exhaust passages cast directly into the cylinder head. This eliminates the need for a traditional separate exhaust manifold and allows the close-coupled catalytic converter to be mounted directly to the cylinder head.

A silent-chain drives the dual overhead cams and features a double-arm tensioner design that reduces operating friction. The cam drive is designed to be maintenance free throughout the life of the engine.

To help boost fuel efficiency and power, the combustion chamber shape and valve angles have been optimized. The included valve angle is a narrow 35 degrees, which decreases the surface-to-volume ratio and helps create a flatter, more compact combustion chamber that reduces unburned hydrocarbon emissions. With this combustion chamber shape and the precise control of direct injection, the compression ratio set at 11.6:1.

The cylinder head features a “tumble port” intake design. In combination with the combustion chamber and piston crown shape, the design’s high level of airflow tumble helps create a homogenous fuel mixture for low fuel consumption and high airflow for high power output.

2.4-Liter Engine i-VTEC® Valve Control System

The Acura TLX’s direct-injected 2.4-liter DOHC 16-valve i-VTEC® engine uses an advanced valve-control system to combine high power output with high fuel efficiency and low emissions. The system combines VTC (Variable Timing Control), which continuously adjusts the intake camshaft phase, with Variable Valve Timing and Lift Electronic Control (VTEC), which changes valve lift, timing and duration of the intake valves.

At low rpm, the VTEC intake valve timing and lift are optimized for high torque and low fuel consumption. As engine rpm builds past 4,900 rpm, the VTEC system transitions to a high-lift, long-duration intake cam profile for superior high-rpm engine power.

The “intelligent” portion of the system is its ability to continuously vary the timing of the intake cam relative to that of the exhaust camshaft. This helps boost power and also provides a smoother idle (allowing idle speed to be reduced). The intake cam timing is varied based on input from sensors that monitor rpm, timing, throttle opening, cam position and exhaust air-fuel ratio. The result is increased fuel efficiency and lower NOx emissions.

3.5-liter V6 Engine

The TLX 3.5-liter i-VTEC® V6 is closely related to the 3.5-liter V6 that powers the Acura RLX and MDX. It has a die-cast lightweight aluminum alloy block with cast-in-place iron cylinder liners, a smooth-firing 60-degree V-angle, and compact overall dimensions. The TLX powerplant combines Direct Injection with i-VTEC® and Variable Cylinder Management (VCM) to give the TLX strong fuel economy ratings and overall performance. This clean-running engine meets ULEV-3 emissions standards in select states, and Federal Tier 3, Bin 125 standards.

The aluminum-alloy 24-valve engine produces 290 horsepower at 6,200 rpm and generates 267 lb-ft of torque at 4,500 rpm.

V6 Engine Block and Crankshaft

With its 60-degree V-angle, the Acura TLX’s available V6 engine has compact overall dimensions that allow efficient packaging within the vehicle. The V6 has a die-cast lightweight aluminum alloy block with cast-in-place iron cylinder liners. Made with a centrifugal spin-casting process, the thin-wall liners are high in strength and low in porosity. The block incorporates a deep-skirt design with four bolts per bearing cap for rigid crankshaft support and minimized noise and vibration. The 3.5-liter V6 uses a high-strength steel crankshaft for minimum weight. A cooling control spacer positioned in the water jacket surrounding the cylinders helps control warm-up and operating cylinder liner temperatures to reduce friction.

V6 Pistons/Connecting Rods

Designed with “cavity-shaped” crowns, the V6 engine’s pistons help maintain stable combustion and contribute to optimized combustion. Ion-plated piston rings help reduce friction for greater operating efficiency. Heavy-duty steel connecting rods are forged in one piece and then the connecting rods are “crack separated” to create a lighter and stronger rod with an optimally fitted bearing cap.

V6 Cylinder Heads and Valvetrain

Like other Acura V6 powerplants (other than the NSX), the TLX engine’s 4-valve cylinder heads are a single-overhead-camshaft design, with the cams driven by the crankshaft via an automatically tensioned toothed belt. Made of low-pressure cast, low-porosity aluminum, each cylinder head incorporates a laminar flow intake design that improves combustion efficiency by creating a more homogeneous fuel-air mixture. An integrated exhaust manifold cast into each cylinder head reduces parts count, saves weight, improves flow and optimizes the location of the close-coupled catalyst.

V6 i-VTEC® with 2-Stage Variable Cylinder Management™ (VCM®)

The Acura TLX SOHC V6 combines Variable Cylinder Management (VCM) with Variable Valve Timing and Lift Electronic Control (i-VTEC®), which changes the lift profile, timing and lift duration of the intake valves. A switching mechanism allows each cylinder to operate with low-rpm valve lift and duration or high-rpm lift and duration. The rear cylinder bank’s valve gear closes all intake and exhaust valves to minimize pumping losses while operating in three-cylinder mode.

The “intelligent” portion of the system is its ability to vary valve operation based on the driving situation and engine rpm. At low rpm, the i-VTEC® intake valve timing and lift are optimized (low lift, short duration) for increased torque, which allows a wide range of 3-cylinder operation. As engine rpm builds past 5,000 rpm, the i-VTEC® system transitions to a high-lift, long-duration intake cam profile for superior high-rpm engine power.

V6 VCM™ Operation – To help improve the fuel efficiency of the TLX engine, Acura’s Variable Cylinder Management™ (VCM™) is used. The system cooperates with Active Control engine Mounts (ACM) to allow the engine to operate with three cylinders in a wide range of situations to maximize fuel efficiency and reduce emissions. When greater power is needed, the system switches seamlessly to 6-cylinder operation.

During startup, aggressive acceleration, or steep ascents – any time high power output is required – the engine operates on all six cylinders. During moderate-speed cruising and at low or moderate engine loads, the system operates just the front bank of three cylinders.

The VCM system can tailor the working displacement of the engine to match the driving requirements from moment to moment. Since the system automatically closes both the intake and exhaust valves of the cylinders that are not used, pumping losses associated with intake and exhaust are eliminated and fuel efficiency gets a further boost. The system combines maximum performance and maximum fuel efficiency – two characteristics that don’t typically coexist in conventional engines.

VCM deactivates specific cylinders by using the i-VTEC (intelligent Variable Valve-Timing and Lift Electronic Control) system to close the intake and exhaust valves while the Electronic Control Unit (ECU) simultaneously cuts fuel to those cylinders.

V6 SH-AWD Idle Stop System

To help improve fuel efficiency, TLX SH-AWD models come equipped with Idle Stop. When the system is active and certain operating conditions are met, the TLX engine will automatically shut off when the vehicle comes to a stop. When the driver releases the brake pedal after a stop, the engine automatically restarts and the TLX is ready to accelerate.

V6 Active Control Engine Mounts and Active Sound Control

A powerful 28-volt Active Control Engine Mount system (ACM) is used to minimize the effects of engine vibration as the VCM system switches cylinders on and off. Sensors alert the Electronic Control Unit (ECU) to direct ACM actuators positioned at the front and rear of the engine to cancel engine vibration using a reverse-phase motion. In the cabin of the TLX, an Active Sound Control (ASC) system further mitigates low frequency noise that can occur during 3-cylinder operation.

There are two different Active Sound Control profiles available in the Acura TLX. When the Integrated Dynamics System is in the ECON or Normal setting, the ASC is tuned for maximum interior quietness; in Sport or Sport+ mode, the ASC allows a more aggressive interior engine and exhaust note.

Remote Engine Start

The V6 TLX with Advance Package offers the ability to start the vehicle’s engine remotely. This enables drivers to start their TLX, thereby activating the climate control system and heated/ventilated seats before they enter the vehicle – perfect for hot or cold days. The remote is designed to have a range of operation of up to 300 feet. To start the engine remotely, the owner presses the LOCK button and then holds the ENGINE button for a few seconds. When the engine is started remotely, the wipers, lighting and audio systems remain off, and the security system remains set. The engine will run for up to 10 minutes after remote starting, and then shut off automatically if the owner doesn’t reach the vehicle within that time. When the owner does get to the TLX within 10 minutes, the engine will keep running while the owner unlocks the vehicle and gets in. This system also provides feedback to the owner to confirm whether the engine is running or the vehicle is locked via the remote’s three LED indicators.

Cold-Air Induction System

To maximize power output, the TLX has a cold-air intake system that picks up air coming through the front grille area, which is typically about 5 percent cooler than the air in the hot engine compartment. Cooler intake air has greater density, which allows the Direct Injection system to add proportionately more fuel for enhanced power output.

Direct Injection System

Both 4-cylinder and V6 TLX engines feature efficient direct injection. The system features a compact, high-pressure, direct-injection pump that allows both high fuel flow and pulsation suppression, while variable pressure control optimizes injector operation. A multi-hole injector delivers fuel directly into each cylinder (not to the intake port, as in conventional port fuel injection designs), allowing for more efficient combustion and greater power output.

Drive-by-Wire™ Throttle System

The Acura TLX Drive-by-Wire™ throttle system replaces a conventional throttle cable with smart electronics that “connect” the accelerator pedal to a throttle valve inside the throttle-body. The result is less under-hood clutter and lower weight, as well as quicker and more accurate throttle actuation. Plus, a specially programmed “gain” rate between the throttle pedal and engine offers improved drivability and optimized engine response to suit specific driving conditions.

Three different throttle profiles are available in the TLX. When the Integrated Dynamics System (IDS) is in the ECON mode, the system uses a gradual profile that encourages fuel savings. In Normal mode, the throttle profile balances economy and performance for all-around driving. When the Sport or Sport+ mode is selected, the system switches to a more aggressive throttle map to enhance responsiveness.

Direct Ignition and Detonation/Knock Control

The TLX’s Electronic Control Unit (ECU) monitors engine functions to determine the best ignition spark timing. Engine block-mounted acoustic detonation/knock sensors “listen” to the engine, and based on this input, the ECU can retard the ignition timing to prevent potentially damaging detonation. An ignition coil unit for each cylinder is positioned above each spark plug’s access bore.

Close-Coupled Catalysts

The exhaust manifolds of both TLX engines are cast directly into the aluminum cylinder heads to reduce weight, decrease parts count, and create more underhood space. The result of this casting design is that the primary catalytic converters are positioned much closer to the combustion chambers, enabling extremely rapid converter “light-off” after engine start. A significant weight savings is realized by eliminating traditional exhaust manifolds.

Emissions Control

Both 2018 TLX engines meet the tough EPA Tier 3/Bin 125 and CARB LEV III ULEV emissions standards, and are certified to this level of emissions performance for 120,000 miles. A number of advanced technologies are factors in the emissions performance. The unique cylinder head-mounted close-coupled catalytic converters light off quickly after engine start up, and a 32-bit RISC microprocessor within the Electronic Control Unit (ECU) boosts computing power to improve the precision of spark and fuel delivery.

Both engines feature Programmed Fuel Injection (PGM-FI) that continually adjusts the fuel delivery to yield the best combination of power, low fuel consumption and low emissions. Multiple sensors constantly monitor critical engine operating parameters such as intake air temperature, ambient air pressure, throttle position, intake airflow volume, intake manifold pressure, coolant temperature, exhaust-to-air ratios, as well as the position of the crankshaft and the camshafts.

Friction-Reducing Technologies

Both Acura TLX engines make use of friction-reducing technologies designed to improve engine efficiency. The outer skirts of lightweight aluminum pistons feature a special coating that reduces overall friction as the pistons move within the cylinder bores. Plateau honing further lowers the friction level between the pistons and the cylinders by creating an ultra-smooth surface. Plateau honing is a 2-stage machining process that uses two grinding processes instead of the more conventional single honing process. This also enhances the long-term wear characteristics of the engine.

One-Touch Start System

To ensure consistent starting, the TLX has a one-touch start system that maintains starter engagement until the engine starts. Should the driver release the Start button before the engine starts, the system will start the vehicle. Simply push the Start button (with a foot on the brake pedal and the key fob in the vehicle) and the engine will automatically start up.

100,000+/- Mile Tune-up Intervals

The Acura TLX’s engines require no scheduled maintenance for 100,000+/- miles or more, other than periodic inspections and normal fluid and filter replacements. The first tune-up includes water pump inspection, valve adjustment, installation of new spark plugs, and in V6 models, replacement of the camshaft timing belt.

Maintenance Minder™ System

To eliminate unnecessary service stops while ensuring that the vehicle is properly maintained, the TLX has an owner-resettable Maintenance Minder™ system that continually monitors the vehicle’s operating condition and all normal service parts and systems, including oil and filter, tire rotation, air-cleaner, automatic transmission fluid, spark plugs, timing belt, coolant, brake pads and more. When maintenance is required, the driver is alerted via a message on the Multi-Information Display (MID).

Sequential SportShift 8-Speed Dual-Clutch Transmission (DCT) with Torque Converter

To maximize performance and fuel efficiency, the 2.4-liter Acura TLX has a standard 8-speed Dual-Clutch Transmission (DCT), which was the world’s first transmission of this type to be paired with a torque converter. For 2018, the transmission has been retuned for a more refined feel. In the 8-speed DCT, one clutch controls the odd gears while the other clutch controls the even gears. This arrangement allows gear changes with a much smaller interruption in power to the wheels, resulting in millisecond-quick shifts.

Compared to a conventional manual transmission, the operation of the clutches and shifting mechanisms are electronically controlled, eliminating the need for a clutch pedal or manual shift lever. The DCT with its closely spaced ratios, ultra-quick shifts and automatic downshift rev-matching, gives the TLX 4-cylinder an exhilarating and sporty feel. The DCT transmission in the TLX also features a steering wheel-mounted paddle shifter system that lets the driver take manual control of transmission gear selection, further heightening the driving experience.

The ultra-thin torque converter complements the efficient operation of the DCT by providing exceptionally smooth operation in stop-and-go situations, plus it offers off-the-line torque multiplication for improved initial acceleration that a DCT alone can’t equal. In an aggressive standing-start launch, the torque converter substantially improves acceleration in the first 1.4 seconds, or about the first 60 feet (compared to a DCT alone).

Sequential SportShift 9-Speed Automatic Transmission

TLX V6 models are equipped with a 9-speed automatic transmission featuring Sequential SportShift. For 2018, the transmission has been retuned for a more refined feel. The transmission features a fully electronic, shift-by-wire gear selector. Park, Neutral and Drive are selected with the push of a button. Reverse is selected by pulling back a dedicated switch. Indicator lights near the buttons indicate the mode selected. As an added safety feature, if the vehicle is brought to a stop in Drive, the system will automatically select Park if the driver’s seatbelt is unbuckled and the driver’s door is opened. As with the DCT, a steering wheel-mounted paddle shifter system lets the driver take manual control of transmission gear selection.

Cooperative Transmission Control

Both shift performance and smoothness are improved by cooperative control between the Drive-by-Wire™ throttle system and the two available transmissions. The engine is throttled by the engine management system during upshifts and downshifts; thus the function of the engine and transmission can be closely choreographed for faster, smoother shifting. As a result, the peak g-forces (or “shift shock”) are reduced significantly during upshifts and downshifts.

Automatic Modes

Both Acura TLX transmissions can be operated in two different, fully automatic modes, which are controlled by the Integrated Dynamics System (IDS). In Econ, Normal and Sport IDS modes, the transmission combines fuel efficiency with smooth operation and responsive power when needed. When the IDS is placed in Sport+ mode, the transmission switches to more aggressive mapping that puts the emphasis on performance-oriented driving, with higher engine rpm for greater acceleration and response.

Smart Transmission Logic

Both transmissions incorporate an advanced Grade Logic Control System, Shift Hold Control and Cornering G Shift Control – all of which reduce unwanted shifting and gear hunting. The result is smart transmission operation that optimizes fuel efficiency and keeps the transmission in the appropriate gear for driving conditions, generating excellent performance and smooth operation.

Grade Logic Control alters the transmission’s shift schedule during ascents to hold the transmission in lower gears to boost climbing power, and during descents to provide greater engine braking.

Shift Hold Control keeps the transmission in its current (lower) gear ratio during aggressive driving, as in the case of decelerating at a corner entry, leaving the chassis undisturbed by eliminating excess shifting and ensures that power will be immediately available at the corner exit.

Cornering G Shift Control monitors the vehicle lateral acceleration to suppress any unwanted upshifts which could upset the chassis balance thus requiring downshifting again when the throttle is applied at the corner exit.

Paddle Shifter Operation in Econ, Normal and Sport Integrated Dynamic System (IDS) Modes

While in Econ, Normal or Sport IDS modes, special transmission logic programming allows the use of the steering-wheel-mounted paddle shifters. When the driver operates the paddle shifters, the transmission responds to the driver’s shift command and then returns to its normal fully automatic mode if further paddle shift inputs are not made within a given time. This special logic makes it easy for the driver to command a quick downshift without leaving the convenience of Drive mode.

Paddle Shifter Operation in Sport+ Mode

When the Integrated Dynamics System is switched to the Sport+ mode, a pull on either paddle shifter places the transmission in fully manual mode until another mode of operation is selected. A digital display in the instrument cluster indicates which gear the transmission is in.

A double-kick-down feature lets the driver command a sport-minded double downshift – such as from Fifth to Third gear. By pulling on the left downshift paddle twice in rapid succession, the transmission will drop directly to the chosen lower gear ratio. The Drive-by-Wire™ throttle system also creates a “blip” of the throttle to help match gear speeds while downshifting.

To prevent harm to the powertrain when the transmission is paddle shifted by the driver (including during double-kick-down shifts), the system will inhibit potentially damaging shifts. As an added safety measure, the Electronic Control Unit (ECU) can also cut off fuel to the engine to prevent over-revving. If fuel cut-off is insufficient to prevent engine over-revving, as may be possible when the vehicle is on a steep downhill, the transmission will automatically upshift to prevent damage. On downshifts, the transmission will not execute a driver command that will over-rev the engine.

Front-Wheel Drive

The TLX offers front-wheel drive, paired with either the 4-cylinder or V6 engine. With its efficient and lightweight design, the TLX front-wheel drive system makes a significant contribution to overall fuel efficiency.

The latest version of Acura Precision All-Wheel Steer® (P-AWS) is standard on all front-wheel drive TLX models, and helps give the TLX best-in-class dynamic performance at all speeds.

The system is complemented by Agile Handling Assist (AHA), which selectively uses the vehicle’s brakes to improve initial turning response and overall cornering ability. AHA applies braking force to the inside wheels during high G cornering to improve corner traceability and provide a confident handling feel.

Super-Handling All-Wheel Drive™ (SH-AWD®)

Available on all V6 equipped models, the Acura TLX SH-AWD features a hydraulically controlled iteration of Acura’s acclaimed Super Handling All-Wheel Drive system, which progressively distributes optimum torque not only between the front and rear axles, but also between the left and right rear wheels. SH-AWD is complemented by Agile Handling Assist to further improve cornering characteristics of the TLX.

The benefits of SH-AWD are superior all-weather handling and neutral, accurate steering under power that is unmatched by front-drive, rear-drive or conventional all-wheel-drive systems.

By rotating the outside rear wheel faster than the front axle while cornering, SH-AWD creates a yaw moment to help turn the vehicle through the corner – reducing understeer and improving controllability. With cornering forces more evenly distributed between front and rear tires, overall cornering power is increased – on wet or dry roads.

Vehicles with high power ratings using conventional front or rear drive systems often employ a limited-slip differential to help maintain traction when under power. By linking inside and outside drive wheels, these systems tend to resist turning and can increase understeer. Conventional AWD systems similarly work to link the inboard and outboard tires as well as the front and rear axles, which can create resistance to turning. Using torque vectoring to help turn the vehicle, SH-AWD delivers more responsive, neutral and predictable handling performance while providing outstanding all-weather handling and control.

Electronic Controls and Parameters

SH-AWD works in cooperation with Vehicle Stability Assist™ (VSA®) system and Agile Handling Assist (AHA) to optimize the TLX’s torque distribution for superior handling and traction utilization. The Electronic Control Unit (ECU) provides information on engine torque, airflow and transmission gear-ratio selection, while the VSA ECU provides wheel-speed data. The SH-AWD system’s ECU also monitors steering angle, steering angle rate of change, lateral G-forces, vehicle yaw rate and hydraulic clutch pressure for the right and left rear axle shafts. Drive torque is calculated from ECU information, and then the acceleration situation, wheel spin, lateral G-force, steering angle and steering angle rate-of-change are used to determine the front-to-rear torque distribution and the torque split between right and left rear wheels.

SH-AWD operating parameters include:

  • Up to 90 percent of available torque can be transferred to the front wheels during normal cruising.
  • In hard cornering and under acceleration, up to 70 percent of available torque can be directed to the rear wheels to enhance vehicle dynamics.
  • Up to 100 percent of the torque sent to the rear axle can be applied to either the left or right rear wheel, depending on conditions.

SH-AWD System Layout – The TLX SH-AWD is a full-time all-wheel-drive system that requires no driver interaction or monitoring, thanks to a torque-transfer unit that is bolted directly to the front-mounted transaxle. The torque-transfer unit receives torque from a helical gear that is attached to the front differential’s ring gear, and a short horizontal shaft and hypoid gear set within the torque-transfer unit’s case send power to the rear propeller shaft, which in turn transfers power to the rear drive unit.

The Acura TLX’s SH-AWD rear drive unit is constantly overdriven by 2.7 percent. The resulting overdrive effect is regulated by left- and right-side clutch packs (located in the rear differential) that independently control the power delivered to each rear wheel. The high overdrive percentage in the TLX means that the torque vectoring effect is pronounced and effective even in corners with a radius of as little as 49.2 feet (15 meters). This means that torque vectoring can be felt often, such as when accelerating aggressively through a standard corner. Up to 885 lb.-ft. of torque can be delivered to either rear wheel, which gives the system the unique ability to yaw the TLX into turns for superior handling.

Hydraulically operated clutch systems mounted on either side of the hypoid gear that drives the rear axles control the amount of torque sent to each rear wheel and provide a limited-slip differential function when needed. The clutches can be controlled as a pair to alter front/rear torque split or they can be controlled independently to allow 100 percent of available rear axle torque to go to just one rear wheel.

In this iteration of SH-AWD, a single electric motor powers a pair of hydraulic pumps – one for each clutch pack. An Electronic Control Unit (ECU) controlled linear solenoid valve selectively sends pressure to the clutch packs, which in turn control the amount of power sent to each rear wheel.

The clutch packs and their friction material are carefully designed to withstand the small amount of continuous slip between front and rear axles created by the 2.7 percent speed differential – all while delivering the durability expected of an Acura product.


Redesigned and significantly enhanced, the 2018 TLX represents the new face of Acura. Inspired by the Acura Precision Concept, the new look is more aggressive, sporty and alluring, creating fresh visual appeal from any angle. Subtle changes to stance, proportion, wheels and sheet metal effectively boost the TLX’s emotion and character.

Front-end styling is completely new forward of the A-pillars, including the diamond pentagon grille, bumper and lower fascia, lighting, hood and fenders. The sculptured fenders and modern, strong hood are defined by crisp character lines that are confident and captivating, matching the TLX’s strong dynamic characteristics and imbuing the redesigned TLX with Acura’s Precision Crafted Performance DNA.

Wheel and tire choices are expanded to four distinct offerings ranging in diameter from 17 to 19 inches. Redesigned side sills direct attention to the rear, where the 2018 TLX showcases one of three unique rear fascia, bumper and exhaust treatments, all boosting the sporty and emotional appeal of the new TLX.

Acura TLX and TLX with Technology Package

Following the recently introduced MDX, the 2018 TLX is the second model to feature Acura’s signature diamond pentagon grille, finished in gloss black with a bright surround and displaying a large 6.4-inch Acura bright badge in the center. Flanking the grille are redesigned Jewel-Eye™ LED headlight arrays using five LEDs per side and surrounded by wing-shaped LED DRLs. Below the distinctive grille, the bumper and lower fascia take on sporty new shapes, with aerodynamic diaplanes at the outer corners of the lower fascia mimicking the look of a racing prototype. Large openings at the corners of the fascia continue the hexagonal grille motif. The new hood is more multidimensional than the previous TLX, with three decisive character lines creating a “power bulge” at the center and giving the TLX front end a bold appearance in a wide range of lighting conditions.

The standard wheels are a new 17×7.5J thin 10-spoke aluminum alloy with a Pewter paint and machined finish on the 4-cylinder TLX, and 18-inch split 5-spoke aluminum alloy with Shark Gray paint and machined finish on the V6 TLX. At the rear of the TLX are redesigned LED taillights with bright trim, a unique new bumper and fascia with hidden dual exhaust tips, an Acura badge at the center of the trunk lid, and a TLX badge on the right side. Safety reflectors are located on the outside edges of the lower fascia. All V6 equipped TLX models have exposed dual exhaust outlets and a sport-inspired four-vane rear diffuser.

Acura TLX V6 A-Spec

Broadening the appeal of the V6 powered TLX for enthusiasts, the exclusive new A-Spec injects even more of Acura’s Precision Crafted Performance DNA. The aggressive styling upgrades start with a unique grille finished with a dark chrome surround and a broad additional opening beneath the bumper that evokes a racecar’s engine air intake. Adding to the A-Spec’s bold presentation is a unique lower fascia with large outer openings featuring round 2.75-inch diameter LED fog lights, likewise highlighted by dark chrome trim. The redesigned Jewel-Eye™ LED headlights use a dark housing for added character.

Unique A-Spec badges are located on the front fenders, while the side windows are surrounded in matte black trim, further distinguishing the A-Spec. The lower side sill garnish is aerodynamically shaped, and the wheels are 19×8.0J split 5-spoke aluminum alloy with Shark Gray paint married to wide 245/40R tires that create a more aggressive stance while sharpening the handling experience.

In back, darker “smoked” taillights, a decklid mounted gloss-black spoiler, and a rear bumper and fascia that are body color above and black below all help to distinguish the TLX A-Spec at a glance. An A-Spec badge is also positioned on the lower left of trunk lid, along with an SH-AWD (when the vehicle is so equipped) badge on the right side. Beneath the rear fascia is an exclusively styled aerodynamic diffuser. Additional unique rear design elements of the bold A-Spec include exposed dual-exhaust outlets with 4-inch round bright finishers, and air vent features finished with black hexagonal grilles at the fascia corners.

Acura TLX V6 Advance Package

The technologically advanced look of the TLX with Advance Package starts at the front with the addition of trapezoidal LED fog lights. On the sides of the vehicle, streamlined lower sills feature bright trim for a sophisticated appearance. The Advance Package also gets unique 18×7.5J split 15-spoke aluminum alloy wheels with Shark Gray paint and a machined finish.

At the rear of the Advance Package is a body-color decklid spoiler similar to that on the A-Spec. Also included on the Advance Package is a rear bumper and fascia that uniquely adds bright finishers at the outer edges, molded in a wing design to mimic the vehicle’s front LED DRLs. Further increasing the sporty character, the Advance Package has unique trapezoidal shaped dual exhausts outlets mirroring the front fog lights and an A-Spec-like rear diffuser.

Overall Design Philosophy

Since its original introduction in 2015, the TLX has been designed to support the twin goals expressed in the car’s “Red Carpet Athlete” theme:

  • Major luxury appeal, represented as cabin quietness, ride comfort and styling refinement.
  • Exhilarating and athletic sports-sedan performance combined with class-leading safety features and ratings.

To achieve these sometimes-competing goals, Acura engineers utilized advanced materials, including ultra-high-strength steel grades, aluminum and magnesium for rigidity, collision performance and weight savings. Special attention was paid to local body rigidity in areas where the body joins the suspension, engine and subframes, and to improvements in body sealing and noise insulation.

The body also is designed to provide a high level of occupant crash protection incorporating Acura’s latest thinking in advanced body design, including the next-generation of the Advanced Compatibility Engineering (ACE) front body structure and one-piece hot-stamped-steel door ring.

Dynamic and Athletic Proportions

With its low and wide stance, the 2018 TLX possesses a lithe exterior form and taut body surfaces befitting a sports sedan. This sporting character is further defined by short front and rear overhangs, dynamically sculpted fender arches, and purposeful character lines. Even the newly re-sculptured hood, with its sharply creased bilateral and central ridgelines, denotes the performance capabilities of the powertrains it conceals. Meanwhile, the open and airy greenhouse provides commanding sight lines, with slim A-pillars providing the excellent visibility necessary for driving enjoyment and safety.

“Just Right” Dimensions

The TLX’s “just right” body dimensions result from a methodical pursuit of aerodynamic efficiency, interior roominess, dynamic performance, quietness and refinement, and of course artistic expression. The redesign of the 2018 model yields minimal dimensional changes compared to the 2017 model. The new TLX has the same 109.3-inch wheelbase, perfectly positioning it between the smaller ILX sports sedan and RLX premium, luxury sedan.

All 2018 Acura TLX share the same 73.0 inch overall width and 57.0-inch overall height with the 2017 model while overall length increases slightly to 191.7 inches (191.5 for A-Spec).

In comparison to its key competitors, the 2018 TLX boasts an overall length greater than the Audi A4, BMW 3-Series, Infiniti Q50, Lexus IS and Mercedes-Benz C-Class sedans. It is also significantly wider than the Lexus ES and Cadillac ATS sedans.

Rigid Lightweight Body

Light weight and rigidity are the twin foundations for TLX comfort, handling and safety performance. Low mass is achieved by a combination of advanced engineering and the use of high-strength steel, magnesium and aluminum unit-body components, while body rigidity is enhanced by precise engineering – particularly in optimizing key component fitting points, bending stiffness and torsional rigidity in the unit-body structure.

Aerodynamic Efficiency

In order to balance performance, fuel efficiency and low emissions, Acura designers blended the TLX’s dynamic styling with aerodynamic detailing. The revised front fascia, hood, fenders and rear fascia on all 2018 TLX trims were tested and proven through the use of sophisticated computational fluid dynamics (CFD), as well as in a scale wind tunnel and in high-precision coast-down testing. Together, these processes help minimize the running resistance (the amount of energy that is lost as the TLX moves along the road and through the air).

Hemmed Rear Wheel Arch

The rear wheel arches use a special roll-hemming process that results in an especially clean edge and smooth appearance. In simple terms, the wheel-arch “hems” are the curved sheet-metal edges that surround the rear tires. In the TLX, a special hemming process is used instead of spot welds to join the inner and outer fender sheet-metal on the inside of the fender opening. The result is a reduced tire-to-fender gap which improves aerodynamics, elimination of visible spot-welds and a cleaner appearance.

High Strength Steel

To achieve the high rigidity that promotes a smooth and quiet ride, crisp steering and handling, safety performance and long-term durability, the TLX utilizes six different grades of high-strength steel (HSS) in 52 percent of its body structure by weight. This high-grade, high-tensile strength steel adds the required rigidity for these positive traits without adding excessive weight, which in turn enhances fuel efficiency and lowers emissions. Altogether, 59 percent of the TLX body is created from a combination of high-strength steel, aluminum and magnesium.

High strength steel uses include:

  • USIBOR – USIBOR is a boron-alloyed steel with an aluminum-silicon coating that protects against oxidation during the heating, forming and hardening process. This high-strength hot-stamp steel is used for the TLX’s door opening rings, for 5 percent of the unit body.
  • 980 grade HSS – Used in certain key structural points such as the front edges of the door sills, and in the A-pillars and B-pillars, for 2 percent of the unit body.
  • 780 grade HSS – Used for most structural load paths for ACE™, including the side sills and forward spars of unit body, for 2 percent of the unit body.
  • 590 grade HSS – Used for the front frame spars, floor and roof supports, for 35 percent of the unit body.
  • 440 grade HSS – Used in the front bulkhead, and in front and rear energy-absorbing structures, for 5 percent of the unit body.
  • 340 grade HSS – Sheet steel is used in the roof, for 3 percent of the unit body.

Aluminum Components

Aluminum stampings are used in certain key locations to reduce the Acura TLX’s curb weight, which provides benefits in handling, fuel efficiency and emissions reductions. Altogether, the aluminum components comprise 6 percent of the TLX’s body weight, a savings of 27.8 pounds compared to comparable steel components.

Among the aluminum body components are:

  • Hood
  • Front bumper beam
  • Rear bumper beam
  • Front subframe (hybrid aluminum/steel)

Magnesium Steering Hanger Beam

Located inside the instrument panel, a 3-piece magnesium steering-hanger beam serves as a structural attachment point for the steering column, pedals and instrument panel, as well as a structural element that helps the passenger cabin retain its shape in certain collisions. This single robust magnesium component makes up 2 percent of the TLX’s body weight.

The steering-hanger beam offers several advantages:

  • Simple construction – Created from just three parts instead of multiple extrusions and stampings, the magnesium steering hanger brace improves construction precision.
  • Light weight – The magnesium steering hanger beam saves 2.7 pounds compared to a comparable aluminum and steel assembly, helping to advance the TLX’s ride and handling, improve fuel efficiency and lower emissions.
  • Exacting fit and finish – The accurate tolerances of the magnesium steering hanger brace allow precise instrument panel fit, improving overall interior quality.

LED Lighting

The newly restyled Acura TLX makes extensive use of versatile, reliable, efficient and effective LED lighting. From the dramatic Jewel Eye™ headlights to the convenient puddle lights and back to the taillights, the LED lighting provides crisp, bright, energy-efficient and long-lasting illumination that directly improves the driving and ownership experience. A summary of exterior lighting includes:

  • Forward Lighting
    • LED headlights and new turn signals
    • LED parking and new side marker lights
    • LED under-mirror puddle lights (Advance Package)
    • LED front fog lights (A-Spec and Advance Package)
  • Rear Lighting
    • LED tail lights
    • LED new side marker lights and trunk-lid lights with incandescent-bulb backup lights
    • LED Center High Mount Stop Lights (CHMSL) with integrated cover
    • LED license-plate lights

Jewel Eye™ LED Headlights

Acura’s redesigned Jewel Eye™ LED headlights give the TLX an advanced appearance while producing superior down-the-road illumination. The headlights utilize an array of high-intensity LED lamps to deliver outstanding light distribution, distant irradiation performance and light characteristics with a wavelength close to the human eye’s luminosity curve. With five “Jewel Eye” lights per side, the LED lights provide improved down-the-road visibility compared to HID and halogen headlights.

On each side of the TLX, the low beams consist of three LED lights, while the innermost LED lights are utilized for high beams. The daytime running light (DRL) function utilizes all five lenses illuminated by LED’s that are clearly and dramatically visible even in bright sunlight. Altogether, they create a dramatic and distinctive appearance with superior lighting capability.

Light distribution

Both the low- and separate high-beam LED headlights offer outstanding performance in all nighttime driving conditions, including highway, winding roads, intersections, and in inclement weather conditions. The result is that the driver can see farther ahead with uniformity, making high-speed nighttime driving easier and less fatiguing.

A summary of LED benefits include:

  • Outstanding light distribution
  • Excellent distant illumination performance
  • Clear illumination of the road surface and white lines
  • High visibility of the entire visible color spectrum (white, red, green, blue and yellow) compared to HID and halogen headlights
  • Response time when switching between low and high beam is shortened
  • Light congruity is improved between low and high beams
  • Reduced power requirement – TLX’s LED headlights use 41 percent less power than traditional halogen headlights, contributing to the TLX’s overall operating efficiency.
  • With an estimated life expectancy of 10,000 hours, the LED headlights are projected to last five times longer than HID headlights and 10 times longer than traditional halogen headlight bulbs.

LED Fog Lights

Included on the A-Spec and Advance Package TLX, LED fog lights are positioned at the lower corners of the front fascia for maximum effectiveness and a bold appearance. The fog lights are trapezoidal on the Advance Package and round on the A-Spec.

LED Taillights

LED taillights are part of the TLX’s comprehensive exterior lighting array. Highly stylized to compliment the TLX body design, they are also brighter than traditional incandescent-bulb taillights, with a longer projected lifespan. Use of LEDs allows the addition of a “light pipe” styling element extending across the top of the lenses, contributing to the TLX’s unique blend of design and engineering.

LED Puddle Lights

Included in the Smart Entry system, LED puddle lights positioned on the undersides of both side mirror housings enhance convenience when entering or leaving the vehicle. The LEDs automatically illuminate when the TLX detects the key fob approaching, in concert with the automatic interior illumination. The puddle lights also illuminate when the driver puts the TLX in Park and leaves the vehicle, fading off after about two seconds after locking the doors, or 30 seconds if the doors are not locked.

LED Side Mirror Lights

Stylistically keying off the Jewel Eye™ LED headlights, each TLX mirror has LED lights fused into the mirror housing. The LEDs illuminate when the turn indictors are activated, providing extra visibility and a high-tech appearance.

Auto-Dimming Side Mirrors

Included in the Advance Package, auto-dimming side mirrors use the same activation sensor as the TLX’s auto-dimming inside rearview mirror. The auto-dimming function of all three mirrors helps reduce glare during nighttime driving, especially from the headlights of following vehicles.

Power Folding Side Mirrors

New for the 2018 TLX, a power-folding feature in the Advance Package allows the outside mirrors to be folded against the body sides when the vehicle is parked, reducing the chance of damage to the mirror housing in tight parking areas. The power-folding feature can be activated by pressing a switch on the driver’s door armrest when the transmission is in Park or Neutral and the ignition switch is in the Accessory or On mode.

Acoustic Glass

To reduce noise in the cabin, the TLX utilizes a 4.5-mm thick, 3-layer acoustic windshield that consists of two layers of safety glass, separated by a thin acoustic resin center. The windshield reduces wind noise on in the higher-frequency ranges, contributing to a luxurious feeling of isolation in the cabin. Also helping to mitigate wind, road and traffic noise in the cabin is 5.0-mm thick front door glass.

Auto Up-Down Side Windows

The 2018 Acura TLX has power front and rear side windows with an auto-open and auto-close feature with anti-pinch.

Advanced Windshield Wiper System

The sleek, flat design of the wiper blades adds to the TLX’s visual appeal. The flat blade design improves aerodynamic performance and reduces wind noise. The driver’s side windshield wiper blade is 26 inches long to efficiently sweep rain from the windshield ahead of the driver. The passenger side wiper is 17 inches long, effectively clearing the right side of the windshield.

Headlights On With Wipers

Laws in some states require drivers to turn on the headlights when the wipers are operating in the rain. The TLX helps its driver comply with these laws by automatically illuminating the headlights when the wipers are activated for five cycles or more (with headlight switch in AUTO).

Rain Sensing Wipers

Included in the Technology, A-Spec and Advance Packages, rain-sensing wipers automatically activate if water is detected on the windshield.

Noise Mitigation

The TLX was designed to deliver vault-like quietness in all driving conditions, with major improvements achieved through enhancements in body stiffness, body and door sealing, and widespread sound insulation.

Acoustic Spray Foam

Applied to the unit body in 10 crucial locations around the door openings, acoustic spray foam helps create a solid foundation for a quieter cabin. The application process is automated and computer controlled, with the foam curing in 7 to 11 seconds after application for a highly precise and effective process.

Additional Materials and Sealing

Additional sound-absorptive materials are used throughout the unit body and interior, each dedicated to blocking a particular noise type and frequency. The materials include Thinsulate insulation, body sealers, noise-absorbing carpeting, and high-density and dual density melt sheets. Liquid Applied Sound Deadening (LASD) is used in the trunk. Key areas of attention include the TLX’s dashboard lower and floor area. The end result is reduced road noise and drumming on both concrete and asphalt surfaces, along with lower engine noise, for a more relaxing and pleasant driving experience.

Wind Noise

Significant reductions in both high-frequency and mid-frequency noise heard in the cabin were achieved by lowering the windshield-wiper height and optimizing the shape of the side mirrors. Special sealing methods in the B-pillars and C-pillars, and between the door gaps, further reduce audible wind noise.

Door Sealing

The TLX has 360-degree double seals that surround each passenger door. In addition, the TLX uses a third set of gap seals, positioned at the front, center, and bottom edges of each door (and the trailing edge of the rear doors) that help eliminate potential noise source caused by turbulent airflow in the cavities around the door hinges and latches. The doors’ internal steel stampings receive further sound insulation in the form of large acoustic hole seals, internal foam sound barriers, and specially targeted B-pillar plugs.

Electric Trunk Lid Release

There are four ways to open the trunk: 1) by pressing the trunk opener switch located on the driver side instrument panel; 2) with the key fob; 3) with the trunk opener switch located in the middle of the trunk, underneath the trunk lid overhang; and 4) if the electric trunk release is inoperative, by using the key stored in the key fob. The trunk’s emergency key cylinder is located beneath a cover near the head restraint on the driver’s side rear seatback.

Trunk Storage

For 2018, all TLX models feature a molded cargo bin (previously only offered on the Advance Package) increasing cargo volume to 14.3 cu. ft. (up from 13.2 cu. ft.). There is no difference in storage capacity for the TLX 2-wheel-drive models and TLX SH-AWD.

The trunk features an easy 27.5-inch load-in height, a broad 44-inch wide opening, and a flat, wide interior floor that makes loading and unloading cargo easier. The flat floor extends from the rear bumper area, forward to the rear seatback for maximum usability. The trunk hinges are fully hidden for a better visual appearance and to eliminate the possibility of catching on stored items. The 60/40 split-folding rear seatbacks allow storage of large or bulky items such as bicycles, skis or boards, or flat-screen televisions.

Cargo Bin System

All TLX models now include a versatile trunk underfloor storage system that provides convenient storage for such items as groceries, emergency tools and other small items. The flip-up floor reveals a 25-inch wide x 11-inch long x 9-inch deep storage bin. This bin is ideal for everyday items such as groceries, shoes, etc. Flipping the floor panel again reveals an additional storage area designed for emergency tools, jumper cables, etc. A molded carrier holding the TLX’s towing eyebolt and tire-inflator kit is also located in this area. Finally, a reversible floor panel — carpeted on one side, plastic on the backside — can be used when wet or messy items like raincoats, umbrellas or beach towels need to be carried in the trunk.

Exterior Colors

The 2018 Acura TLX is offered in eight desirable exterior colors, including one solid, two metallic and five pearl. All colors have a strong character, offering expressive contrasts that complement the 2018 TLX’s new body-panel curves and angles, while also exhibiting a smart luxury appearance. The acid-resistant epoxy clear-coat paint is superior to typical clear-coat paints for increased resistance to urban pollutants.

Comfort and Convenience

The TLX is replete with a wide range of standard and available comfort and convenience features. A Multi-Angle Rearview Camera is standard, and a newly available Surround-View Camera System comes standard with the Advance Package. A-Spec and Advance Packages also include a wireless charging pad in the front console that can charge compatible devices.

The Smart Entry Keyless Access System with front door and trunk access is standard on all TLX models, and on the Technology Package and above, Smart Entry access is expanded to include the rear doors. The 2018 TLX with Advance Package also adds remote engine start that can be activated with a range of at least 300 feet from the vehicle, allowing the vehicle to be pre-heated or pre-cooled and defrosted/defogged based on the customer’s preselected settings.

Smart Entry and Push Button Start/Stop

All 2018 TLX models offer the upscale convenience of Smart Entry and Push Button Start/Stop.

Smart Entry

The Smart Entry system simplifies approaching, entering and operating the TLX – especially when the driver has his or her hands full. To gain entry to vehicle, the driver simply pulls one of the two front door handles (or rear on Tech Package and above) while the remote is in his or her possession.

Push Button Start/Stop

Once the driver has opened the door and is seated, the driver simply pushes the START/STOP button positioned on the instrument panel while pressing the brake pedal to start the vehicle. For accessory mode the driver simply presses the START/STOP button without pressing the brake pedal.

Remote Engine Start

The Acura TLX with Advance Package provides the ability to start the vehicle’s engine remotely, thereby activating the climate control system before they get to the vehicle. The remote is designed to have a range of operation of at least 300 feet.

To start the engine remotely, the owner presses the LOCK button and then holds the ENGINE button for a few seconds. When the engine is started remotely, the wipers, lighting and audio systems remain off, and the security system remains set. The engine will run for up to 10 minutes after remote starting, and then shut off automatically if the owner doesn’t reach the vehicle within that time. This system also provides feedback to the owner to confirm whether the engine is running or the vehicle is locked via the remote’s three LED indicators.

Walk Away Auto Lock®

The new Walk Away Auto Lock feature automatically locks the TLX when the driver leaves the vehicle. This hands-free locking capability adds everyday convenience that’s especially useful when the driver has his or her hands full or is distracted. In typical use, when all doors are closed and the driver walks away, the TLX will automatically lock when the key holder’s distance from the vehicle exceeds 6.5 feet for two seconds or more and when no other key is detected inside the vehicle. An audible buzzer sounds and the hazard lights flash to confirm that the vehicle has locked. The Walk Away Auto Lock feature is programmable, and may be turned on or off as the driver prefers.

Leather-Wrapped Steering Wheel

The leather-wrapped steering wheel incorporates the most commonly used controls, allowing the driver to keep their hands on the wheel. Phone and audio controls are on the left side; cruise control and multi-info display controls are on the right side, along with the switches for Lane Keeping Assist System (LKAS) and Adaptive Cruise Control with Low-Speed Follow. Tucked out of view but within fingertip reach is a pair of paddle shifters that allow for manual operation of the Sequential SportShift transmission. The TLX A-Spec has a special steering wheel with a thicker rim and an A-Spec badge.

Heated Steering Wheel

The TLX with Advance Package offers the comfort and luxury of a heated steering wheel. A switch on the lower left side of the steering wheel can be activated when the ignition is switched on, and is also integrated to the Remote Engine Start System for automated heating when appropriate. Acura Genuine Accessories also offers an optional heated steering wheel for other TLX models.


Seating in the TLX is designed for all-day comfort, combined good lateral support for aggressive cornering. The TLX with Technology Package enjoys perforated premium Milano leather seating while V6 equipped models add contrasting stitching and piping. The TLX V6 A-Spec features specially contoured front seats with enhanced lateral support.

New for 2018, the TLX V6 with Technology Package, A-Spec and Advance Package add a standard driver’s seat power thigh extension. The front passenger seat offers 4-way power adjustment on 4-cylinder models, and 8-way power adjustment on V6 equipped cars.

Heated front seats are standard in the TLX. Electronic control allows for three temperature settings, along with fast warm-up and smooth, precise temperature control. Ventilated and heated front seats are standard in the A-Spec and Advance Packages. The Advance Package also includes heated rear outboard seats.

The driver’s seat has a 2-position memory and an easy entry/exit function that moves the seat rearward when the front door is open to increase room for entry and exit. Additionally, specially sculpted front seat seatbacks offer extra legroom for rear seat passengers.

A 60/40 split-folding rear seatback allows the TLX to accommodate long cargo, or to combine one or two rear seat passengers with long cargo.

Wireless Device Charger

New for 2018, TLX A-Spec and Advance Package models have a standard wireless charging pad positioned at the front of the center console. It’s compatible with a wide range of devices, and provides convenient recharging without the hassle of a wired connection.

HomeLink® Remote System

All Acura TLX models feature a HomeLink® universal remote system, located in the overhead control panel, which works with nearly all garage door openers and gates systems, and an ever-growing list of other radio frequency (RF)-controlled devices.

Driver Preferences

All TLX models come with two keyless remotes with unique identifiers. Each remote can be set with unique profiles to accommodate the individual preferences of two different drivers. The available preferences include driver seat and mirror positions, along with select HVAC functions. Other preferences include turning entry lights on or off, audio system pre-sets, air conditioning preferences, and navigation system settings.

Capless Fueling System

The TLX features a capless fueling system that eliminates the traditional fuel cap, meaning that fueling the vehicle simply requires opening the fuel lid, refueling, and then closing the lid. This smart and easy-to-use design eliminates the need to touch a dirty fuel cap, reduces the possibility of damaging the vehicle’s paint with the fuel cap or tether, or forgetting the fuel cap at the gas station. It also eliminates the possibility of activating an emissions warning by failing to properly reinstall the fuel cap.

Hill Start Assist

The Hill Start Assist function helps to prevent the vehicle from rolling backwards when the driver switches from the brake pedal to the accelerator pedal while the vehicle is stopped on a hill. Hill Start Assist automatically activates when the vehicle senses a certain incline and is fully stopped in any forward gear when facing up hill or reverse gear when facing downhill. Hill Start Assist, when activated, will release the brakes when the driver depresses the throttle or if the driver doesn’t press the accelerator after a few seconds.

Multi-Angle Rearview Camera

A multi-angle rearview camera is standard on the TLX. It offers three viewing angles (wide view, normal view and top view). The rearview image is displayed on the 8-inch color upper display. On-screen guidelines help the driver better judge distances, and predictive guidelines help make maneuvering in reverse easier.

Surround-View Camera System

New for 2018, the TLX V6 with Advance Package features four exterior cameras providing a 360 view of the space immediately around the vehicle through the navigation display. A camera button among the display controls changes camera views.

One-Touch Power Moonroof with Tilt Feature

The Acura TLX features a power tilting and sliding moonroof with a manual sunshade. To tilt or slide the moonroof, the driver or front passenger needs only to fully press the ceiling-mounted switch once (instead of pressing and holding it for several seconds). The moonroof fully opens or closes automatically.

Dual-Zone Automatic Climate Control – GPS-Linked

The TLX has a GPS-linked (when equipped with navigation system) temperature control, dual-zone automatic climate control system that lets the driver and front passenger set temperatures to their individual liking.

Easy-to-read buttons and controls are positioned within convenient reach. The HVAC system can also be controlled by voice command, and additional custom settings can be accessed through the 7-inch On-Demand Multi-Use Display™ interface.

With its position-sensing ability, the GPS navigation system (standard on Technology Package and above) contributes to overall passenger comfort with a 3D solar sensing feature. Based on continuously updated vehicle position information, the navigation system determines the position of the sun relative to the driver and passenger. Combining this information with input from a solar sensor located on top of the instrument panel, the climate control system automatically adjusts the temperature from side to side as needed to compensate for asymmetrical solar heating. On the A-Spec and Advance Package, the heated and ventilated front seats are electronically linked to the climate control system.

Active Noise Control (ANC) and Active Sound Control (ASC)

Key contributors to the Acura TLX’s quiet, refined interior are Active Noise Control (ANC) and Active Sound Control (ASC). The two systems are comprised of dual overhead microphones, an ANC/ASC electronic processor, and the audio system’s speakers. ASC/ANC operates whenever the engine is running, even if the audio system is turned off.

ANC is designed to reduce low frequency sound in the cabin caused mainly by the roughness of the road surface. The overhead microphones pick up sound waves and send them to the ANC/ASC processor, which creates and sends a precisely timed “reverse phase” audio signal to a special amplifier. In turn, the amplifier drives the door speakers to cancel the original noise signal.

ASC is a related technology designed to improve the engine sound quality by making the sound pressure level more linear as the engine revs increase. Typically, engine noise doesn’t increase in a linear way with rising revs; instead there can be many resonances that create peaks and valleys in the sound pressure level and an uneven sound. ASC helps smooth out the engine sound by creating a same-phase or reverse-phase sound signal as needed and sending it to the speakers. Though the system offers benefits from idle to redline, it makes the largest difference in the range between 1,400 and 2,400 rpm (V6) and 1,000 and 1,800 rpm (4-cyl.), where it lowers the sound pressure level with a reverse-phase audio signal.

ASC is part of the Integrated Dynamics System (IDS). When the IDS is in ECON or Normal mode, the ASC system is tuned for a smooth, unobtrusive engine sound. When the IDS is switched to Sport or Sport+, using the Dynamic Mode switch positioned on the center console, the TLX’s interior engine sound takes on a more aggressive note.

ASC is further enhanced on A-Spec models, increasing engine noise in the cabin by as much as 4 dB at engine speeds above 4,000 rpm contributing to a sporty and fulfilling driving experience.

In addition to a traditional auxiliary source input, the TLX is fitted with a USB port in the front center console that allows for easy connectivity to items such as an iPod® or iPhone®, or a removable flash drive storage device containing WMA, MP3 or AAC format music. The 2.5-amp port can be used for data and/or charging.


The Acura TLX chassis incorporates the latest versions of two pinnacle Acura handling technologies – Precision All-Wheel Steer™ (P-AWS) standard on the front-wheel drive TLX models, and Super Handling All-Wheel Drive™ (SH-AWD®) on the V6 powered all-wheel-drive models. Both systems are engineered to deliver intuitive and precise dynamic capabilities in a vehicle that responds directly and accurately to the will of the driver.

These technologies are anchored by the TLX’s rigid unit-body structure and its MacPherson strut front and multi-link rear suspension with Amplitude Reactive Dampers (ARD). Stable and responsive vehicle dynamic behavior is further aided by Acura’s Agile Handling Assist (AHA) technology and, in more severe maneuvers, by Vehicle Stability Assist™ (VSA®).

These chassis features define the most advanced Acura TLX to date from a dynamic standpoint, a vehicle that supports the needs of the driver in almost any condition: quick and responsive in sporty driving environments; stable and sure-footed in emergency maneuvers; calm and quiet during long-distance cruising.

The Acura TLX also allows a substantial degree of customization through its Integrated Dynamics System (IDS) with four modes – ECON, Normal, Sport and Sport+ settings – that take the TLX from relaxing to racy all at the touch of a button.

Unique A-Spec Features

Components that help the new TLX A-Spec surpass all previous TLX models in steering and handling are low-profile 245/40R 19-inch tires and sport-tuned suspension, including dampers and revised electric power steering (EPS); springs and rear stabilizer bar on SH-AWD models; and Precision All-Wheel Steer™ (P-AWS) algorithms on front-wheel drive models. These changes markedly improve steering response, handling, feedback and grip with minimal compromise in ride comfort. This furthers the updated 2018 TLX’s appeal as a sport sedan, while still maintaining the ride quality and low noise levels expected of a luxury sedan.

The A-Spec’s revised electric power steering (EPS) results in greater responsiveness at vehicle speeds above 42 mph, compared to other 2018 TLX models. The specially tuned A-Spec steering system also contributes to greater on-center steering feel.

In addition, wider wheels (8.0 inches instead of 7.5 inches as on other TLX models) and low-profile 245/40R19 Michelin Primacy MXM4 tires, which provide 20 mm greater width and a stiffer sidewall, help improve steering response and overall grip.

Front Cast-Aluminum and Steel Subframe

The TLX employs a cast-aluminum and steel “hybrid” front subframe to reduce road surface vibration and shock inputs for a smooth, quiet ride. The subframe supports the engine, transmission, front suspension and steering system. The front section of the subframe is steel, and the rear section is cast aluminum. The sections are joined with a friction-stir-welding process to form a single high-strength, lightweight unit that provides ideal ride and handling properties. Altogether, the front subframe, along with a lower arm hydro-bushing, reduces vertical and fore/aft forces felt at the front seats.

MacPherson Strut Front Suspension

MacPherson strut front suspension with Amplitude Reactive Dampers provides precise and engaging handling performance, a responsive feel for the driver, and luxurious ride quality. Specially tuned hydro-compliance bushings improve resistance to shimmy and also reduce the potential for brake judder, further boosting the TLX’s refinement and driving character. SH-AWD models have an increased spring rate compared to front-wheel drive models.

Rear Steel Subframe

Constructed of high-tensile steel, the rear subframe uses hydraulic mounts, along with high fitting-point stiffness, to reduce road surface vibration and shock inputs for a smooth ride and low noise. The rear subframe reduces vertical and fore/aft forces felt at front seats. In addition, on TLX models with Super-Handling All Wheel Drive (SH-AWD), the rear subframe features a 4-point differential mounting system. Its bushing rates are specially calibrated to reduce the transmission of driveline noise and vibration into the vehicle body, while also helping to maintain ride quality.

Multi-Link Rear Suspension

Multi-link rear suspension with Amplitude Reactive Dampers provides optimal handling agility, driver confidence and ride sophistication. Geometry, including rear toe control, is optimized for handling competence, stability and a sophisticated ride in a variety of urban, highway and open-road driving scenarios. The system includes multi-link control arms, control-arm bushings that are optimized for the best blend of noise, vibration and harshness (NVH) isolation and handling precision, and Amplitude Reactive Dampers.

Acura TLX SH-AWD models have an increased spring rate as compared to front-wheel drive TLX models. Both the 4-cylinder TLX and V6 SH-AWD models have a 24.7-mm diameter rear stabilizer bar, while the front-wheel drive V6 has a 25.4-mm diameter rear stabilizer bar. The TLX A-Spec SH-AWD has a larger 25.4 mm rear stabilizer bar that further enhances turn-in and reduced body roll during cornering.

Amplitude Reactive Dampers (ARD)

Acura’s Amplitude Reactive Dampers provide both superior ride comfort and sporty handling, helping the TLX provide a truly engaging driving experience in all driving situations. Two separate damping mechanisms are utilized, with one tuned for maximum efficiency on smoother roads with small inputs and the other tuned to handle large inputs such as rough roads, potholes, and sudden steering and braking action. Front triple-path damper mounts further improve ride comfort without sacrificing handling. The result is a vehicle that remains composed and comfortable in a wide range of conditions.

Amplitude Reactive Dampers have two separate damping pistons. To improve overall ride comfort, when smaller inputs occur during normal driving conditions, only the main piston works to provide the ideal damping characteristics. To improve the TLX’s ride and handling during more severe conditions, a second piston operates to provide additional damping force.

Amplitude Reactive Dampers operate on a purely mechanical/hydraulic basis and do not require electronic controls.

Vehicle Stability Assist™ (VSA®)

The Acura TLX’s Vehicle Stability Assist™ (VSA®) works in conjunction with the Drive-by-Wire throttle system and ABS to enhance vehicle stability when cornering: If vehicle understeer or oversteer is detected, the system selectively reduces power and/or applies braking force to individual wheels to help correct the condition and stabilize the vehicle.

VSA also supports the operation of available driver-assistive technologies such as Adaptive Cruise Control (ACC) with Low-Speed Follow, Collision Mitigation Braking System™ (CMBS) and Road Departure Mitigation (RDM). The advantages of the TLX’s VSA system include quick response with smooth activation, highly accurate control and brake-pedal feel, and low operating noise, vibration and harshness (NVH).

In addition, VSA monitors wheel slippage, such as when starting on slick surfaces or patches of ice. If slippage is detected, VSA activates one or more brake calipers and reduces engine torque to slow the spinning wheel(s) so traction can be regained. VSA is included on all front-wheel drive and SH-AWD models.

Integrated Dynamic System (IDS)

ECON, Normal, Sport and Sport+ modes allow the driver to customize their driving experience. The modes are driver-selectable via a console-mounted button (labeled “Dynamic Mode”) and are displayed on the Multi-Information Display located between the tachometer and speedometer. ECON, Normal and Sport are selectable as default, or last-used modes, while Sport + defaults to Sport at ignition off, and must be reselected after a restart. ECON mode favors high fuel efficiency, while Normal mode is for everyday driving. Sport mode enhances throttle, EPS and P-AWS response or SH-AWD rear-wheel torque-vectoring control to sharpen vehicle dynamics, while Sport+ mode enhances transmission shift mapping, maximizing performance.

Motion-Adaptive Electric Power Steering (MA-EPS)

The TLX’s Motion-Adaptive Electric Power Steering offers precise direct feel, high energy-efficiency, tunable response and robust active safety. MA-EPS responds instantly to steering input and automatically changes the amount of power assist appropriate to the vehicle’s speed. Its idealized steering effort and linearity, excellent on-center feel, minimal torque steer and maximum parking ease provides a satisfying driving experience under all conditions.

Additional features and benefits include:

  • Quick steering ratio helps provide a sharp, sporty dynamic response.
  • High-stiffness bushings improve steering precision and feel.
  • Next-generation control logic provides smoother feel on rough roads.

Motion-Adaptive Function

The Motion-Adaptive EPS system consists of a rack-and-pinion steering gear with an electric motor installed concentrically around the steering rack. To control the level of assist the Powertrain Control Module receives signals from a speed sensor and, coupled with a steering sensor for torque and rotation, then calculates the optimal amount of assist and sends a signal to the electric motor.

When compared to the operation of a conventional hydraulic pump power steering system, the simpler MA-EPS increases efficiency because it does not draw a continuous amount of power directly from the engine. Other advantages of electric power-assisted steering include simplicity, and compactness.

Vehicle Stability Assist™ (VSA®) Integration

MA-EPS and Vehicle Stability Assist™ (VSA®) work together as one sophisticated system to significantly enhance active safety. The stability technology initiates steering inputs that prompt the driver to steer in the correct direction when the limits of traction are approached.

Using vehicle speed and steering angle data, MA-EPS works with VSA to detect instability in low traction conditions (both during cornering and under braking) and automatically initiates steering inputs aimed at prompting the driver to steer in the correct direction. This advanced technology supports the driver’s action in operating the vehicle more safely and comfortably.

Below are three examples of how MA-EPS works as part of VSA.

  • Mitigates Understeer – Helps correct steering inputs to mitigate understeer and help the driver trace the curve of the road.
  • Mitigates Oversteer – Helps correct steering inputs to mitigate oversteer and help the driver trace the curve of the road.
  • Stabilizes Braking – Helps correct steering input to reduce vehicle instability when braking hard on road surfaces with varying friction coefficients (such as pavement that is only partially covered with dirt or snow).

Integrated Dynamics System (IDS) Integration

MA-EPS also integrates with the TLX’s standard Integrated Dynamics System (IDS). At the driver’s discretion, the steering response can be switched between two distinct steering settings (Normal: when in Normal or ECON, and Sport: when in Sport or Sport+).

Precision All-Wheel Steer™ (P-AWS)

Standard on all front-wheel drive TLX models, Precision All-Wheel Steer™ (P-AWS) helps the Acura TLX driver smoothly and easily trace the desired line with smaller steering-wheel inputs. The result is outstanding dynamic performance at all speeds, providing the TLX driver with the most engaging driving experience possible.

P-AWS provides independent electronic control of rear-wheel toe angles. Benefits of the system include:

  • Minimized turning radius with neater execution of sharp low-speed turns
  • Improved response for quick steering maneuvers such as lane changes
  • Enhanced agility and nimbleness in tight, urban conditions
  • More confidence and control on curved highway on- and off-ramps
  • Greater agility on winding roads
  • Quicker and more effective emergency steering response
  • Increased straight-line highway stability
  • Confident braking stability
  • Improved high speed response and stability in winter driving and when Vehicle Stability Assist™ (VSA®) is activated

P-AWS Operation

Key components of P-AWS include independent electrically assisted left/right toe-control actuators, special control arms and suspension uprights and an electronic control unit that is linked via a dedicated Control Area Network (CAN) to the Electric Power Steering (EPS), Vehicle Stability Assist™ (VSA®), braking and engine control systems.

In operation, P-AWS continuously monitors and calculates the correct amount of rear-toe angle input necessary for the conditions, analyzing steering input, engine and road speed, transmission, throttle position, brake pressure, yaw rate, lateral acceleration and other factors. The maximum amount of rear-wheel toe angle adjustment is 1.8 degrees in either direction (positive or negative) for a total range of 3.6 degrees.

P-AWS automatically and continually adjusts the toe angle of each rear wheel to match driving situations such as turning at an intersection, driving on windy roads, merging or exiting a highway, high-speed maneuvers or snowy conditions. The P-AWS system provides confidence-building cornering capability through improved responsiveness and vehicle control. Examples include:

  • Secure Highway Cruising – When the driver initiates a lane-change maneuver requiring that the TLX neatly move into the next lane, the P-AWS system adjusts the rear wheel toe angles in phase (the same direction) with the front wheels enabling quick, clean and stable maneuvering.
  • City Agility and Easy Parking – For sharp low-speed turns, such as on city streets or in parking lots, the P-AWS system adjusts the rear wheel toe angles out of phase (the opposite direction) with the front wheels. This results in a tighter turning radius and reduces driver effort.
  • Fun to Drive on Winding Roads – When tracing the lines of a twisty road (or helping the TLX track confidently in snowy conditions) the P-AWS system counteracts understeer by helping introduce yaw – the necessary rotational effect – through the corner.

Agile Handling Assist (AHA)

Agile Handling Assist (AHA) extends the P-AWS function by using the brakes in cornering to create yaw, or turning motion, helping the driver smoothly and easily trace the desired line with smaller steering-wheel inputs. AHA stabilizes the car earlier than conventional vehicle stability assist systems, resulting in more agile and engaging dynamic performance in everyday driving conditions.

Super Handling All-Wheel Drive™ (SH-AWD®)

The TLX SH-AWD features a hydraulically-controlled iteration of Acura’s acclaimed Super Handling All-Wheel Drive (SH-AWD), which progressively distributes optimum torque not only between the front and rear axles, but also between the left and right rear wheels. Like its P-AWS counterpart, the TLX SH-AWD system is complemented by the brake torque effect of Agile Handling Assist.

The benefits of the SH-AWD system are superior all-weather handling and neutral, accurate steering under power. By rotating the outside rear wheel faster than the front axle while cornering, SH-AWD uses torque vectoring to create a yaw moment to help turn the vehicle through the corner – reducing understeer and improving controllability. With cornering forces more evenly distributed between front and rear tires, overall cornering power is increased – on wet or dry roads.

4-Wheel Disc Brakes with ABS and Brake Assist

The Acura TLX is equipped with 4-wheel disc brakes with a 4-channel anti-lock braking system (ABS). The pedal feel is smooth and easy to modulate in light braking, and linear and pleasantly low-effort during medium and hard braking. The result is short, confident stops – with excellent pedal feel – under all conditions.

The front discs measure 12.6 inches in diameter, while the rear discs measure 12.2 inches in diameter. Optimizing the mass of the rotors and calipers helps improve ride quality, handling capability and fuel efficiency, while also delivering outstanding braking performance.

6-Piston Brake Modulator

The TLX employs a 6-piston brake modulator that provides the ultra-quick braking response required for Vehicle Stability Assist™ (VSA®), Active Handling Assist (AHA), low-speed follow operation, Road Departure Mitigation (RDM), and Collision Mitigation Braking System (CMBS). The brake modulator utilizes six pistons to build braking pressure almost instantaneously, delivering quick braking response.

Electric Parking Brake (EPB) and Automatic Brake Hold

The combination of Electric Parking Brake (EPB) and Automatic Brake Hold meaningfully reduce the effort of driving the vehicle, thereby raising overall enjoyment and comfort for the driver.

Electric Parking Brake

The Electric Parking Brake (EPB) on the Acura TLX makes using the parking brake easier and more comfortable, requiring only a pull on a button on the center console to activate. To release the parking brake, the driver simply presses on the accelerator pedal (while the seatbelt is buckled) or pushes on the parking brake switch. In addition to being simpler, more convenient and more comfortable to use than a traditional parking brake, the Electric Parking Brake makes hill starts easier when the TLX is parked on a grade.

The one-touch operation also promotes the use of the parking brake. As with a traditional manually activated parking brake, EPB functions on the rear wheels only. As an additional benefit, EPB weighs 9.7 pounds less than a traditional mechanical parking brake, helping to improve the TLX’s overall performance and fuel economy.

Automatic Brake Hold

The EPB also features Automatic Brake Hold, which retains brake pressure when the vehicle is stopped, simplifying driving in heavy traffic or hills. This frees the driver from continually pressing the brake pedal to maintain the vehicle in a stopped position, a significant improvement in driving enjoyment in difficult conditions.

Operating the system requires two simple actions from the driver:

  • Activating/deactivating the system via a switch on the center console
  • Pressing on the brake pedal when the vehicle comes to a stop

Aluminum Alloy Wheels

The 2018 TLX 4-cylinder features an all-new thin 10-spoke aluminum alloy 17×7.5J wheels with a Pewter paint and machined finish. Standard on V6 equipped models is a sporty split 5-spoke aluminum alloy 18×7.5J wheels with a Shark Gray paint and machined finish. Included with the V6 Advance Package are luxurious 15-spoke, 18×7.5J aluminum-alloy wheels. Finally, the new TLX A-Spec gains additional performance appeal with 19×8.0J wheels sporting a split 5-spoke design and finished in Shark Gray paint. In addition, 19-inch aluminum-alloy wheels are available as an accessory for all TLX grades.

The wheel bearings are engineered with special low-drag seals that contribute to a 4.4 percent decrease in rolling resistance compared to traditional wheel bearing seals.

High-Performance All-Season Tires

All TLX models feature high-performance all-season tires that help deliver an ideal balance of ride and handling, high fuel efficiency, and low noise, vibration and harshness (NVH). Four-cylinder TLX models have 225/55R17 97H high-performance all-season tires, while the TLX V6 has lower-profile 245/50R18 95H high-performance all-season tires for enhanced driving performance. The new TLX A-Spec has 245/40R19 94V M+S tires for further performance gains. All tires offer precise steering feel, high levels of grip in all-season driving conditions, and low rolling resistance for greater fuel efficiency.

In the TLX A-Spec, the wide and lower profile 19-inch performance tires, together with the revised suspension tuning, offer significant performance benefits with only a slight compromise in mid-frequency road noise. And impressively, high-frequency cabin noise levels are reduced from previous TLX models.

Tire Pressure Monitoring System (TPMS)

A standard Tire Pressure Monitoring System (TPMS) helps the driver maintain proper air pressure to improve driving safety and fuel efficiency, as well as reduce wear and tear on the vehicle’s tires. Located in the Multi Information Display (MID), the TPMS graphic indicates the pressure in all four tires on a real-time basis. A TPMS icon illuminates to alert the driver whenever any of the tires has a significantly low-pressure reading that requires the driver’s attention.

Fill Assist

All TLX models include Fill Assist, a feature that helps the driver inflate tire pressures to the correct level without using a pressure gauge. Instead, during inflation, Fill Assist sounds an audible alert when the tire reaches the required pressure.

Tire Repair Kit

The TLX features an easy-to-use tire repair kit in lieu of a spare tire. This reduces weight and increases trunk volume, and simplifies temporary repairs in the event of a flat tire. Acura Roadside Assistance supports tire repairs. In addition, a temporary spare wheel and tire are available as a Genuine Acura Accessory.

Capless Fueling System

The Acura TLX’s capless fueling eliminates the fuel cap, meaning that fueling the vehicle simply requires opening the fuel lid, refueling, and then closing the lid. This smart and easy-to-use design eliminates the need to touch a dirty fuel cap, reduces the possibility of damaging the vehicle’s paint with the fuel cap or tether, or forgetting the fuel cap at the gas station. It also eliminates the possibility of activating an emissions warning by failing to properly re-install the fuel cap. And finally, the capless fueling system allows the use of a smaller fuel-cap door, which cleans up the lines of the vehicle.

17.2-Gallon Fuel Capacity

The Acura TLX’s plastic fuel tank capacity of 17.2 gallons gives the TLX ample cruising range. The fuel tank is made of high-impact plastic for weight reduction and durability. The fuel tank is located in a protected area in front of the rear suspension.

Safety and Driver Assistance

The 2018 Acura TLX offers the highest level of standard safety and driver-assistive features in model history, positioning it as the only Entry Premium Sedan with both crash avoidance and active driving assist features standard.

A vehicle’s safety performance starts with its dynamic capabilities. Acura engineers targeted a high level of predictability, precision and stability in the TLX’s steering, braking and emergency handling capabilities. In the event of a collision, the many integrated active and passive safety features help to mitigate the potential for injury. These features include the newest generation of Acura’s Advanced Compatibility Engineering™ (ACE™) body structure and a new one-piece, high-strength steel door stiffener ring, along with advanced airbag and seatbelt restraint systems. Acura engineers also targeted the highest available safety ratings from the National Highway Traffic Safety Administration (NHTSA) and the Insurance Institute for Highway Safety (IIHS).

Further, for the first time, all 2018 TLX trims are equipped with the AcuraWatch™ suite of driver-assistive technologies that help to improve the driver’s situational awareness and, in certain circumstances, intervene to help avoid a collision or mitigate its severity.

Next-Generation Advanced Compatibility Engineering™ (ACE™) Body Structure

The TLX utilizes the latest version of Acura’s Advanced Compatibility Engineering™ (ACE™) body-structure to enhance occupant protection and crash compatibility in frontal collisions. The ACE body structure uses a network of interconnected structural elements – now using an even greater amount of high-tensile steel – to absorb and distribute crash energy away from the passenger compartment. The enhanced frontal crash energy management can also help to more evenly disperse the forces transferred to other vehicles in a crash. Additionally, ACE helps minimize the potential for under-ride or over-ride situations that can happen during frontal impacts with a larger or smaller vehicle.

Collision Safety Ratings

The ACE body design helps the 2018 TLX target the highest available crash safety ratings. In federal National Highway Traffic Safety Administration (NHTSA) testing, the TLX targets a 5-Star Overall Vehicle Score. In Insurance Institute for Highway Safety (IIHS) testing, the TLX targets a SUPERIOR rating in the front crash prevention on all trims thanks to standard application of AcuraWatch™ with Collision Mitigating Braking System™ (CMBS®).

Crash Energy “Pathways”

Unlike most conventional designs that direct frontal crash energy only to the lower load-bearing structures in the front end, the next-generation ACE body actively channels frontal crash energy to both upper and lower structural elements, including the floor frame rails, side sills and A-pillars. By creating specifically engineered “pathways” that help distribute these frontal impact forces through a greater percentage of the vehicle’s total structure, the ACE body can more effectively route crash energy around and away from the passenger compartment to help limit cabin deformation and further improve occupant protection.

Structural Safety

Meeting the TLX’s crash-safety rating targets required numerous structural engineering advancements including side collision-load pathways and the use of hot-stamped high-strength steel – including a one-piece door opening stiffener ring – helping improve occupant protection in side impact collisions.

Hot-Stamped Stiffener Ring

The TLX uses a hot-stamped stiffener ring around both door openings. There are three major advantages of this construction method: (1) The one-piece door-opening ring has no joints, so crash loads are transferred more efficiently; (2) the single-piece construction improves the fit and finish of the door opening; and (3) weight is reduce by 9.0 pounds compared to a conventional multi-part ring.

To form the ring, a single steel blank is loaded into an oven and heated to 940º Centigrade, then formed and quenched in a single stamping and tempering process.

Airbag System

The Acura TLX is equipped with seven airbags, including advanced front airbags, front side airbags, side-curtain airbags with rollover sensor, and a driver’s side knee airbag.

Driver’s Side Knee Airbag – The driver’s knee airbag is designed to better position the driver in the event of a frontal collision, to take greater advantage of the protection provided by the front airbag and seatbelt. The knee airbag is contained beneath a panel on the underside of the instrument panel. For improved knee clearance, the panel is contoured away from the driver’s knees.

Advanced Front Airbags (SRS) – Every TLX is equipped with advanced front airbags (SRS). Front airbags are designed to supplement the seat belts to help reduce the likelihood of head and upper body injuries in frontal crashes.

Driver and Front Passenger Side Airbags – Driver and front passenger side airbags mounted in the outboard area of each front seatback are designed to help provide pelvis and thorax protection in the event of a severe side impact.

Side Curtain Airbags with Rollover Sensor – All outboard seating positions include a side curtain airbag system. In the event of a sufficient side impact or rollover, the side curtain airbags deploy from the ceiling, providing a significant level of head protection in the window area. Compared to previous systems, the TLX’s new side curtain airbags have a wider deployment profile, and remain fully deployed for an extended time to further mitigate the possibility of an occupant being ejected from the vehicle.

Adjustable Head Restraints

All five front and rear seating positions feature individually adjustable head restraints while the TLX’s front head restraints feature the latest generation of neck protection performance.

Child Safety Features

Two Lower Anchors and Tethers for CHildren (LATCH) child seat-mounting positions are built into the outboard rear seats. The LATCH system utilizes both an upper child-seat tether anchor and dedicated lower-anchor points that are built into the body of the vehicle. These help ensure correct mounting of a compatible child seat. A third upper tether is located in the rear center position. The TLX also features childproof rear door locks. When engaged, they permit the rear doors to be opened only from the outside, thereby helping to prevent accidental opening by a child.

Adaptive Cruise Control (ACC) with Low-Speed Follow

Now included in all TLX models, Adaptive Cruise Control (ACC) allows the driver to set a desired speed and following interval behind a vehicle detected ahead, allowing the use of cruise control in light highway traffic conditions. This significantly reduces the driver stress of driving in traffic. The system uses Millimeter Wave Radar and a Monocular Camera to continually track the distance to the vehicle ahead, and then adjusts the TLX’s speed to maintain the driver selected following interval. A short, medium, long, or extra-long interval can be selected. When required, the TLX automatically brakes using the Vehicle Stability Assist™ (VSA®) modulator to maintain the set interval.

Integrated Low-Speed Follow, which uses the same Millimeter Wave Radar, Monocular Camera, and VSA modulator, extends the automatic following capability to stop-and-go traffic situations (down to 0 mph). ACC with Low-Speed Follow functions include the following:

  • A preceding vehicle is detected in the lane ahead – Decelerates automatically, if required, and then controls the following interval.
  • The preceding vehicle slows to a stop – Stops automatically and remains stationary.
  • The preceding vehicle accelerates from a stop – Resumes following when the SET or RES switch or accelerator pedal is operated.
  • Another vehicle is detected merging in between the TLX and the preceding vehicle – Automatically switches “targets” to the nearest detected vehicle.
  • The preceding vehicle exits the lane – ACC with LSF system continues at cruise-control speed previously selected by driver (25 to 90 mph).

A Multi Information Display (MID) message and audible warning alert the driver when either ACC or Low-Speed Follow functions are activated.

Collision Mitigation Braking System™ (CMBS™)

Included in all Acura TLX models for the first time, Acura’s latest version of its Collision Mitigation Braking System™ (CMBS™) is one of the most sophisticated driver-assist technologies available. It continually scans traffic conditions ahead of the TLX, alerts the driver when it determines there is potential for a collision, and then applies automatic emergency braking to help reduce the severity of a collision if drivers don’t take corrective action on their own.

When CMBS determines there is a potential for collision, visual and audible alerts prompt the driver to take corrective actions. The visual alerts appear on the Multi-Information Display (MID), with another visual warning on the windshield via the head-up warning display. If the system determines that a collision is imminent, it applies the brakes to help reduce vehicle speed and eventual collision forces.

Further assisting TLX drivers, CMBS also recognizes shapes, and can differentiate between a vehicle and a pedestrian, warning the driver when either is detected. A Millimeter Wave Radar unit located behind the front grille and a Monocular Camera mounted at the upper portion of the windshield are used to detect vehicles and pedestrians. The radar unit and camera work simultaneously and cooperatively to control the VSA modulator, which provides any required braking. This “fusion” of radar and camera allows the system to more quickly determine a whether there’s a potential for a collision, significantly increasing the likelihood of bringing the car to a complete stop and avoiding impact.

It is important to note that CMBS cannot detect all objects ahead, nor is it intended to replace the driver’s assessment of traffic conditions and control of the vehicle. The driver must intervene in certain situations, and must always be attentive when using the system. Although in many cases CMBS will stop the car, it is not intended to apply enough braking force to prevent all collisions. Based on the conditions, the system also may not perform all visual-, audible- and tactile-alert stages, and may instead automatically engage the brakes if the system deems it necessary.

Forward Collision Warning (FCW)

Now included in all TLX models, Forward Collision Warning (FCW) uses a camera mounted in the upper portion of the windshield to detect vehicles and pedestrians ahead and to determine whether a collision is imminent. If the FCW system detects a vehicle or pedestrian in front of the TLX and then determines that a collision may occur (due to a speed differential between the TLX and the object), it will trigger a “BRAKE” message on the Multi-Information Display (MID) and an audible alert. If the CMBS system is activated and the driver fails to respond to the FCW system, the vehicle’s brakes will be automatically applied if the system determines a collision is imminent.

Drivers may adjust the distance at which FCW alerts occur and may choose between “Long,” “Normal,” or “Short.” Drivers may also select “Off” to disable the FCW system entirely.

Note that the FCW system cannot detect all objects ahead; accuracy will vary based on weather, speed and other factors.

Lane Keeping Assist System (LKAS)

Now included in all TLX models, the Lane Keeping Assist System (LKAS) provides a less stressful driving experience by reducing steering correction movements and driving effort on the highway. LKAS uses a camera to read lane markings and uses EPS to assist the driver in keeping in the middle of the lane.

Designed for the U.S. road structure, the system uses a Monocular Camera mounted on the upper portion of the windshield to identify painted lanes, Botts’ dots and cats eye markers at speeds between 45 mph and 90 mph. When LKAS senses that the driver is drifting from the middle of a detected lane, the system generates corrective steering torque to assist the driver in maintaining lane position.

Road Departure Mitigation (RDM)

Included in all TLX models for 2018, Road Departure Mitigation (RDM) uses a Monocular Camera (mounted on the upper portion of the windshield) to identify solid or dashed painted lane lines, Botts’ dots and cats eye markers. RDM uses both steering force, via EPS, and braking force, via VSA, to help the TLX stay in its lane.

The Monocular Camera recognizes lane features and identifies the lane. If the RDM system detects that the TLX is about to leave the detected lane, it will provide steering assist (primary) and in rare occasions when steering is not sufficient, braking assist, to help the driver stay on the road. Only lane departure is activated if the driver is passing over a dashed line, Botts’ dots or cats eye, while deceleration support is disabled. In this case, TLX uses active steering force to return to the lane. RDM is integrated with the Vehicle Stability Assist™ (VSA®) system to provide moderate braking, and with the Electric Power Steering (EPS) system to provide steering input.

Multiple visual and audible warnings alert the driver when the RDM system is taking corrective action. These include a lane departure warning on the driver’s Multi Information Display (MID) along with an audible warning.

RDM also has a customizable initial warning of either a steering wheel shake/vibration, or an audible alert. This can be customized in the vehicle settings.

Multi-Angle Rearview Camera

A multi-angle rearview camera is standard on the TLX. It offers three viewing angles (wide view, normal view and top view). Drivers may select the preferred view according to driving conditions. The rearview image is displayed on the 8-inch color upper information display. On-screen guidelines help the driver better judge distances, and predictive guidelines help make maneuvering in reverse easier.

Surround View Camera System (Advance Package)

In the Acura TLX with Advance Package, four exterior cameras provide a 360-degree view of the space immediately around the vehicle through the navigation display. A camera button among the upper display controls changes camera views.

When Reverse is selected, the rear camera view appears on screen along with an overhead 360- degree view. Guidelines appear in each view, which correspond with the angle of the front wheel’s angle to show the vehicle’s predicted rearward path. A press of either camera button switches to show the rear view alone, and another press shows a wide-angle rear view.

Pressing either “Camera” button when not in reverse shows the 360-degree view combined with a front view that is ideal for putting the vehicle in the ideal position in the garage. Another button press provides a front wide-angle view that is useful for helping spot an approaching vehicle or person when nosing out a tight spot with a blocked side view. Additional views include looking ahead from both sides and just the passenger side view alone.

Blind Spot Information (BSI)

Included in the Technology Package, Advance Package and A-Spec, the blind spot information (BSI) system uses two radar sensors to continually monitor conditions behind the TLX and alert the driver if another vehicle is detected in close proximity – especially in the blind spot of the driver. The BSI system uses the LED indicators (mounted on the A-pillar) and an audible warning to alert the driver.

There are two warning levels: 1) If a vehicle is detected in the driver’s blind spot then the LED indicator on the incoming side illuminates; and 2) If a vehicle is detected and the TLX turn signal is activated, the LED indicator on the incoming side blinks and a buzzer sounds three times.

To prevent false alarms while maneuvering at low speed, the BSI system is disabled below approximately 20 mph.

Rear Cross Traffic Monitor

Included in the Technology Package, A-Spec and Advance Package, the Rear Cross Traffic Monitor works in conjunction with the TLX’s BSI radar sensors to enhance driver confidence and safety when backing up. The system is especially useful when reversing in congested parking lots with an obstructed view from driver’s seat.

The system utilizes a pair of blind-spot radar units located in the rear bumper corners. When Reverse is selected and an approaching vehicle is detected, arrows indicating the approaching vehicles direction are shown on the 8-inch upper display’s rear camera image. Simultaneously, an audible warning is emitted if cross-traffic is approaching from either side.

Pedestrian Injury Mitigation

The Acura TLX has an impact-absorbing front body design to help reduce injury in the event of a frontal collision with a pedestrian. Research shows that the following features can dramatically improve a pedestrian’s chance of survival if struck by a moving vehicle:

  • Impact-energy absorbing hood – Space is provided between the underside of the hood and key powertrain components, allowing the hood to bend and deform if contact is made with either an adult or a child pedestrian.
  • Energy-absorbing fender mounts and supports – Front fender mounts and brackets are designed to deform easily to help absorb impact energy.
  • Deformable windshield wiper pivots – Wiper pivots are designed to deform and break away easily.
