In a thrilling development for electric vehicle enthusiasts and racing fans alike, Formula E has officially begun testing its next-generation Gen4 race cars. A recent video shared on X (formerly Twitter) by Tesla expert Nic Cruz Patane showcases the sleek black prototype emerging from a garage and hitting the track, highlighting the cutting-edge technology set to redefine sustainable motorsports. This move comes as Formula E pushes the boundaries of EV performance, with the Gen4 cars promising unprecedented power, efficiency, and excitement on the circuit.
The footage, captured at what appears to be a high-altitude test track surrounded by mountainous terrain, shows mechanics carefully maneuvering the car out of the hangar before it accelerates onto the asphalt. The vehicle demonstrates impressive handling through corners, with its aerodynamic design and all-wheel-drive system on full display. This testing phase marks a significant milestone as Formula E prepares for the Gen4’s debut in the 2026-2027 season, building on the series’ commitment to zero-emission racing.

Breaking Down the Gen4 Specs: A Leap in Electric Racing Technology
The Gen4 race car is engineered to be the fastest and most advanced electric single-seater yet, incorporating breakthroughs in power delivery, regeneration, and charging capabilities. According to official details from the FIA and Formula E, here’s a comprehensive look at the key specifications:
| Feature | Details |
|---|---|
| Peak Race Power | 450 kW (approximately 600 hp), boosting to 600 kW (over 800 hp) in Attack Mode |
| Regenerative Braking | Up to 700 kW, allowing for energy recovery during deceleration |
| Drivetrain | All-Wheel Drive (AWD) for enhanced traction and performance |
| Battery Capacity | 55 kWh, optimized for high-efficiency racing |
| Fast Charging | 600 kW during pit stops, adding about 4.05 kWh in just 30 seconds |
| Weight | 1,012 kg (2,231 lbs) including the driver |
| Acceleration | 0-60 mph in approximately 1.8 seconds |
| Dimensions | Larger than Gen3 Evo, with aggressive aero kits in low and high downforce configurations |
These specs represent a near-doubling of power from the current Gen3 models, where maximum output tops out at 350 kW. The inclusion of AWD is a game-changer, enabling better cornering and acceleration out of turns, while the massive regenerative braking system could make races more strategic, with drivers harvesting energy to extend stints or unleash boosts.

How Gen4 Builds on Formula E’s Legacy and Compares to F1
Formula E has always been at the forefront of electric innovation, serving as a testing ground for technologies that trickle down to consumer EVs. The Gen4’s active all-wheel drive and ultra-fast charging echo advancements in road cars from manufacturers like Porsche and Nissan, who are deeply involved in the series. For instance, Stellantis Motorsport has been spotted testing Gen4 prototypes in low-downforce setups, focusing on tire development and overall handling.
Compared to Formula 1, the Gen4 could rival or even surpass F1 cars in straight-line acceleration, thanks to its electric torque delivery. While F1 hybrids emphasize hybrid efficiency, Formula E’s all-electric focus aligns with global shifts toward sustainability. As noted in development videos, the Gen4 was built from a blank slate to maximize speed and tech integration.
