By Lorenzo Bianchi February 16, 2026
Facelifted exterior with closed grille and revised front detailing.
Pure electric variants offer up to 530 hp and 708 km range.
New range-extended version pairs 1.5L engine with 200 kW electric motor.
Facelifted Exterior with Sharper Identity
Official images of the 2026 Arcfox Alfa S5 confirm a measured but deliberate update to the mid-size sedan. As a facelift model, the car introduces revised exterior detailing while retaining its underlying proportions.
The front end now adopts a fully closed grille, a visual cue consistent with electric models. Narrow headlights flank the fascia, while double C-shaped air intakes and flat lower inlets add a more athletic expression. Multiple raised character lines on the bonnet introduce a hint of muscular tension without overwhelming the clean surface language.
In profile, the Alfa S5 maintains its fastback silhouette. Hidden door handles and new multi-spoke two-tone wheels contribute to a streamlined appearance. A two-tone body option enhances contrast, and a new green exterior colour joins the palette
At the rear, changes are minimal. A continuous taillight assembly remains, centred by an illuminated ExtremeFox brand logo.
Dimensionally, the sedan measures 4820 (or 4886) mm in length, 1930 mm in width and 1480 mm in height, riding on a 2900 mm wheelbase
The stance is wide and low, consistent with its positioning in the competitive mid-size electric segment.
Options for Pure Electricity Performance There are still single-motor and dual-motor pure electric versions of the 2026 Arcfox Alfa S5 available. With a maximum output of 252 horsepower and 320 Nm of torque, the single-motor version offers well-balanced performance for everyday use. The performance envelope is greatly enhanced by the dual-motor version. The front and rear motors' combined output is 530 horsepower and 690 Nm of torque.
Those figures place the Alfa S5 among the more powerful sedans in its class.
Battery choices include 64.8 kWh, 74.4 kWh and 79.2 kWh packs
Corresponding pure electric driving ranges are quoted at 560 km, 668 km, 630 km and up to 708 km, depending on configuration
The spread allows buyers to prioritize either extended range or higher performance.
New Range Extended Variant
In addition to the pure electric models, the 2026 Arcfox Alfa S5 introduces a range-extended powertrain to broaden its market reach
This version uses a 1.5-litre engine functioning solely as a range extender, producing a maximum power output of 77 kW
The electric motor in this configuration delivers up to 200 kW
A 27.4 kWh battery pack enables a pure electric driving range of 175 kilometres before the range extender engages
This variant was added to accommodate users who need more overall driving flexibility while still having a significant amount of electric-only capability.
