About the Car
2020 Renault Megane RS Trophy-R
Over the last 15 years, the Megane-based Renault Sport versions have set the hot hatch standard for ultimate performance and driving thrills. In that time the most radical versions of the Megane RS have successively beaten the front-wheel drive production car lap record for the hugely challenging Nürburgring, a circuit that’s recognised around the world as the ultimate proving ground for a car’s performance.
The New Renault Megane RS Trophy-R is no exception, setting a new record of 7 minutes 40.1 seconds around the tortuous track famously known as the ‘Green Hell’. Yet unlike competitors that simply focus on delivering ever higher power outputs, the engineers at Renault Sport have concentrated on three distinct performance pillars: weight reduction, the maximisation of aerodynamic efficiency and more radical suspension systems. This approach is a Renault Sport trademark, an approach that priorities speed through the corners rather than outright performance in a straight line.
Featuring an impressive weight reduction of 130kg, a totally redesigned suspension set-up and modified aerodynamics the New Megane RS Trophy-R is the most extreme Renault Sport model yet. It also boasts some innovations that are normally the preserve of high end supercars, such as the optional carbon ceramic brakes and carbon fibre wheels. And in its pursuit of undiluted driving pleasure it removes items such as the rear seats, while the composite Sabelt seats can be ordered with six-point racing harnesses – this is a car that puts the driver front and centre.
Identified by its unique mother-of-pearl paint finish and red highlights (front blade, side stripes, double lateral diamonds graphics and the spokes of the Fuji-Light wheels), its Trophy-R monograms, its carbon components in the bonnet and rear diffuse and its “shark fin” aerial. Inside, the racing atmosphere is underlined by the Alcantara® racing seats, a material that also adorns the racing steering wheel and handbrake lever. A numbered plaque on the door sill emphasizes the exclusiveness of this limited production model.
Of course, New Renault Megane RS Trophy-R is also a car developed using Renault Sport’s extensive motorsport expertise. As a result, the New Megane RS Trophy-R is a hot hatch ready for the racetrack. With greater traction, speed through corners and braking endurance, it is capable of bringing intense pleasure to expert drivers that want to make the most of its incredible potential. Such is the level of the Megane RS Trophy-R that it can easily compete with models that feature four-wheel drive and well in excess of 300 bhp.
This exceptional car will be made available as a limited series of just 500 numbered vehicles globally.
WEIGHT-SAVING
The New Renault Megane RS Trophy-R benefits from a truly remarkable weight reduction of 130kg, when configured with its lightest equipment and compared to the standard Trophy version without options. As a result it tips the scales at just 1,306 kg, representing a power to weight ratio of 230 PS/per ton compared to 209 PS/per ton for the Trophy, despite both sharing the same impressive 300 PS turbocharged 1.8-litre engine. As a result, the 0-62mph sprint now takes just 5.4 seconds – a full three-tenths faster than the Trophy.
This incredible reduction in mass is achieved in a number of ways, each one designed with the expressed intention of squeezing more performance from an already potent package. For instance, the exterior and mechanicals of the New Megane RS Trophy-R benefit from the following enhancements:
- Carbon composite bonnet: at 8kg this panel is half the weight of the standard car’s steel item. Carbon fibre is used for the distinctive NACA air intake and the bonnet lining, while the rest of the louvered panel is fibreglass. As a further touch, New Megane RS Trophy-R uses the lighter opaque and hollow Renault grille badge usually reserved for models equipped with adaptive cruise control.
- Entirely carbon rear diffuser: not only lighter than the standard unit it helps generate extra aerodynamic downforce.
- Wheels: the design of the Fuji Light 19″ alloy wheel (optional on the Trophy) creates a weight saving of 2kg per corner, while the optional Carbon Revolution carbon wheel slices a further 2kg per wheel and is a world first in this sector.
- Akrapovi titanium exhaust: not only does this contribute to a weight saving of over 6kg, it also delivers a more authentic Developed to meet road and track noise regulations it has also been designed to integrate perfectly with the aerodynamics of the rear diffuser, plus it continues a Akrapovi’s working relationship with Renault Sport that goes back to the Megane RS 275 Trophy.
- Bespoke lighter rear axle: this unit brings a significant 32kg saving over the Trophy, which is largely down to the decision not to use 4CONTROL steering for New Renault Megane RS Trophy-R. With the improved front axle and lighter weight, the required improvements in agility could be gained with a non-directional rear axle, while the need for the standard car’s high speed stability was not something that was demanded by expert drivers.
- Optional air intake to replace the R.S. Vision driving lamps: available as an option, this extra unit fits into the nearside lower trim panel normally occupied by the R.S. Vision driving lamps. Using an accessory pipe it feeds directly into the engine air intake. In combination with an identical looking but blanked off insert on the offside this option results in a 2kg saving in weight and slightly reduced overhanging mass, subtly reducing the polar moment of inertia for improved agility.
- High performance DESS lead battery: standard fit is a Dual Energy Storage System (DESS) battery that delivers increased performance for its size, while an optional lithium DESS battery offers a 4.5kg weight saving and is available from the online store as an accessory (R.S.com).
The inside of the New Megane RS Trophy-R hasn’t escaped the engineers’ forensic pursuit of weight-saving. Almost the entire interior has been reworked in an effort to minimise mass and increase performance, with the following changes:
- Sabelt composite monocoque racing seats: Finished in grippy and hard-wearing Alcantara® these figure-hugging one-piece seats offer a weight saving of approximately 7kg per seat. Both seats can be set at three different heights using the lightweight subframe, while a Sabelt six-point harness is available as an accessory. Specific Renault Sport trim colours mean they integrate seamlessly with the rest of the cabin.
- Removal of rear seats: By ditching the rear bench an impressive 3 kg has been stripped from the kerbweight. On cars with the optional carbon fibre wheels there are four separate storage bags, straps, netting and a cradle for the wheels. These can be accessed using the rear doors, which remain operational, and the tailgate. Furthermore, there is a thinner boot floor that saves 1.3kg and is marked with an R logo.
- Thinner glazing, sealed rear door windows and deletion of rear wiper: the front and rear side windows get thinner and lighter glazing, saving 1kg, while the rear doors get fixed glass panes, which allows the removal of the electric window mechanisms and motors. In a similar vein, the rear wiper, its motor and wiring loom have been deleted, resulting in a 3kg saving.
- 7.0-inch infotainment screen: the obsessive pursuit of weight reduction is highlighted by the use of the smaller 7.0-inch infotainment system, which saves 250g compared to the standard Trophy’s 8.7-inch screen. However, the reversing camera is carried over, helping to avoid any risk of damaging the carbon diffuser when manoeuvring!
SUSPENSION
With the same engine power as the standard Trophy, the New Megane RS Trophy-R has been developed to deliver its increased performance through the corners. Not only has the axle geometry been revised to increase speed through the bends and traction on the exit, there are also many options for fine-tuning adjustments by the driver, essentially making the new New Renault Megane RS Trophy-R a true racing car for the road. In their pursuit of maximum suspension performance on road and track Renault Sport’s engineers have undertaken the following changes:
- Revised front suspension: the New Megane RS Trophy-R benefits from a heavily revised suspension with its own geometry. Just like a racing car, the front axle keeps its independent pivot and has the negative camber increased by 1° compared to that of the Megane RS Trophy, taking the figure to -2.05° in total. As a result the tyre contact patch is maintained during high cornering loads, allowing higher speeds through bends and better traction on the exits.
- Torsen® limited slip differential: carried over from the Trophy is the limited slip differential that improves traction both in a straight line and out of corners, allowing drivers to use more of the engine’s power for a faster exit speed.
- Lightened H rear axle: the New Megane RS Trophy-R features a bespoke rear axle, which saves 32kg. Crucially, the new set-up does not use the 4CONTROL four-wheel steering, the resulting weight-saving being much more appreciated by expert drivers than the fractional loss in high-speed stability.
- Öhlins dampers: engineered in collaboration with Swedish suspension specialists Ohlins, these dual flow dampers make a major contribution to the dynamic efficiency of the New Renault Megane RS Trophy-R. At both the front and rear these units can be adjusted for body height (lowering the ride by up to 16mm) and compression/rebound, while further tuning is offered by the adjustable bump stops.
- Rear strut brace: by removing the rear seats it has been possible to add a strut brace that improves the torsional rigidity of the bodyshell.
- Bridgestone Potenza S007 tyres: Developed specifically for Renault Sport, the Potenza S007 is standard on the New Megane RS Trophy-R (and optional on the Trophy). Delivering remarkable response in terms of steering and optimum grip for extreme driving, the tyres are the first to get a specific R.S. marking on the wall. This is a high performance tyre that can be used every day yet is capable of enabling a record-breaking run on the Nordschleife.
- Standard Brembo brakes: braking efficiency is naturally improved by the weight reduction measures on the New Megane RS Trophy-R, yet tthe dual material 355 mm front brake discs from Megane RS Trophy are combined with new Brembo four piston callipers that feature larger 42mm pistons (the Trophy’s have a 40mm diameter).
- Carbon ceramic brake upgrade: the optional carbon ceramic discs feature an even larger 390mm diameter to virtually take up all the available space behind the 19″ wheel. These are clamped by a Gold finished Brembo four piston (44mm top and 42mm bottom) callipers embossed with the Renault Sport logo. Due to the increased braking performance revised ABS and ESP calibrations were necessary, ensuring consistent pedal pressure and bite during extreme driving. This gives New Renault Megane RS Trophy-R the ultimate braking performance and unbeatable endurance, even during extended track work. In addition, the disc’s carbon-ceramic material considerably lengthens operational
- Multi-Sense: as on the Trophy, the Multi-Sense set-up allows drivers to tailor the steering, throttle and ambient lighting to suit the situation and mood.
AERODYNAMICS
As with the rest of the car, the aerodynamic performance of the New Megane RS Trophy-R was put under the microscope. Any design choices made were done so with the sole aim of optimising performance. As a result, engineers were able to deliver greater front and rear downforce while limiting aerodynamic drag. All changes made were verified both using CFD (computational fluid dynamics) and results gained in the wind tunnel.
At the front the New Megane RS Trophy-R benefits from a new bonnet with NACA intake, which combines with a similar vent under the engine to improve the air flow by seven percent and optimise cooling of the engine compartment during extreme hard driving. When at a standstill the new lateral louvres set into the bonnet work in combination with the NACA duct to provide a natural escape for engine heat build-up.
The bottom blade under the front bumper has been also been redesigned to provide better aerodynamic balance between the front and rear, while the new fairings under the front bumper and under the floor smooth air flow to optimise supply to the rear diffuser.
This entirely carbon fibre rear diffuser is equipped with thinner, F1-type curved blades that feature an even larger effective surface area in the central section in particular. Furthermore, the twin exit Akrapovi titanium exhaust features tailpipes that are cut to follow the profile of the diffuser, helping to minimise any disruption in the central airstream. By maximising the airflow in this way engineers have delivered increased downforce compared to the Megane RS Trophy. achieve this same objective,
A further enhancement is the optional dynamic air intake that replaces the R.S. Vision driving lamps, normally set low in the front bumper, which helps lower air intake temperatures. Available as an accessory is a ducting pipe that extends this intake straight into the engine air filter unit.
On top of all this, new brake scoops double the air flow to the front discs, further improving braking endurance in severe conditions.
ENGINE AND GEARBOX
Given the high specific power rating already achieved by the the Megane RS Trophy’s MR18 engine (with 300 PS it delivers an extremely impressive 167 PS per litre), Renault Sport concluded that it had more than enough performance for the lighter and even more focused New Renault Megane RS Trophy-R.
To recap, however, the 1.8-litre direct injection turbo four-cylinder unit develops 300 PS at 6,000 rpm and delivers a muscular of 400 Nm of torque. Its turbocharger makes use of a technology originating directly from Formula 1, the ceramic ball bearing coating both reducing response time and easily coping with the heat and stresses of spinning at up to 200,000rpm.
Underlining the unit’s robustness is the fact that it was chosen by Renault Sport Racing as the basis for the engine used in the latest generation of Formula Renault single seat racer used in the demanding Formula Renault Eurocup championship.
Renault Sport engineers chose the six-speed manual gearbox for the New Megane RS Trophy-Ras it is lighter than the dual clutch EDC transmission, plus it is more in keeping with the car’s focus on expert drivers.
In combination with the significant weight-savings the new engine delivers impressive performance:
- Max speed: 163mph
- Acceleration 0-62 mph: 5.4 seconds
- Acceleration 31-75mph in 3rd gear: 2.9 seconds
- Standing kilometre: 24.5 seconds
Furthermore, the engine is equipped with a petrol particle filter and meets the Euro 6d temp standards.
