Electric racing has always been about progress—each generation of redefining what’s possible for battery-powered performance. From the original Gen1 car that barely completed a race on a single battery to the sleek, aerodynamically advanced Gen3 that pushed 200 mph, every leap has mirrored the rapid evolution of itself. Now, the newly unveiled Gen4 signals another turning point; one that blends raw speed, cutting-edge control systems, and true sustainability into a single statement of intent for the sport’s future.
Set to debut in the 2026–27 ABB FIA Formula E World Championship, the Gen4 car represents a substantial step forward in both engineering and purpose. It delivers 450 kW (around 603 hp) in race trim and up to 600 kW (over 800 hp) in Attack Mode, nearly 200 hp more than the outgoing Gen3 machine. The boost is complemented by a new permanent all-wheel-drive system, which, unlike the Gen3’s limited use of front-axle regeneration, remains active throughout the race. This not only improves acceleration and grip but also introduces an unlimited traction control system and anti-lock braking for sharper, more consistent handling.

Energy recovery has also been significantly enhanced. The Gen4’s regenerative braking now peaks at 700 kW compared to Gen3’s 600 kW, allowing for faster recharge during races and fewer compromises on pace. Its usable battery capacity rises to 55 kWh from 51 kWh, enabling teams to adopt more flexible strategies while sustaining higher outputs for longer durations. Combined with new aero options, high-downforce for qualifying and low-downforce for race conditions, the car offers tunable performance that better suits diverse circuits and race formats.
Visually and structurally, the Gen4 is sleeker yet more responsible. Built from 100 percent recyclable composites and containing at least 20 %percent recycled material, it reinforces Formula E’s environmental focus. The design is a collaboration between the FIA and Spark Racing Technology, refined with input from manufacturers such as Porsche, Nissan, Jaguar, Stellantis, and Lola, all of whom are integrating lessons from the track into road-going EV programs.
When compared to its predecessor, the Gen4 is more than just a performance upgrade; it’s a philosophical evolution. The Gen3 prioritized efficiency and lightweight engineering, but the Gen4 couples that efficiency with unprecedented power delivery and stability. It bridges the gap between electric precision and traditional motorsport spectacle, pushing top speeds beyond 209 mph while maintaining a smaller carbon footprint than ever before.
As Formula E enters this new era, the Gen4 car embodies the championship’s original promise – to make electric racing not only sustainable but thrilling. The sport is no longer proving that EVs can perform; it’s demonstrating how they can outperform. For fans and engineers alike, the Gen4 marks the moment electric racing stops chasing its combustion past and starts shaping motorsport’s electric future!
