Formula E Gen‑4 specs revealed
Formula E’s Gen‑4 cars are a step change: they’ll pack 815 hp in Attack Mode, hit roughly 200 mph, run all‑wheel drive, use a 55 kWh battery, deliver ~700 kW regen braking that can harvest about half the race’s energy, and support 600 kW fast charging — plus organizers say the cars use 100% recyclable materials and motors will be over 90% efficient.

Electric racing cars do not win by carrying giant batteries. Formula E cars win by using a relatively small battery and then clawing energy back every time the driver slows down, like a shopping cart that recharges itself when you squeeze the handle. (fiaformulae.com) That energy clawback is called regenerative braking, which means the motor works in reverse under braking and turns the car’s motion back into electricity instead of dumping it all as heat into the brakes. Formula E says its current cars already recover nearly half the energy they use during a race. (fiaformulae.com) Now the series has shown what comes next: the Gen4 car will arrive in Season 13 in 2026/27, and Formula E says it will be the fastest car in the championship’s history. The governing body, the Fédération Internationale de l’Automobile, says the new car is designed to push electric racing closer to top-tier single-seater performance. (fia.com) (fiaformulae.com) The headline number is power. Formula E says Gen4 will produce up to 600 kilowatts in race trim and about 600 horsepower, with Attack Mode lifting that to 700 kilowatts, or roughly 815 horsepower. (fiaformulae.com) (fia.com) Top speed rises to about 210 miles per hour, which is roughly 338 kilometers per hour. That is a big jump for a series built around tight street circuits where short bursts of acceleration matter more than long straight-line runs. (fiaformulae.com) (fia.com) The other big change is all-wheel drive, which means the front and rear wheels can both put power to the road instead of only the rear axle doing the work. Formula E calls Gen4 the first open-wheel race car with active all-wheel drive running through every phase of the race. (fiaformulae.com 1) (fiaformulae.com 2) That matters most when the car launches out of slow corners on dusty city streets. More driven wheels means more grip, and Formula E says the system is meant to improve traction, agility, and overtaking rather than just add headline speed. (fiaformulae.com) The battery is still small by road-car standards at 55 kilowatt-hours, which is about the size of a modest family electric car pack, not a giant luxury sedan pack. The trick is that Gen4 is supposed to pair that battery with up to 700 kilowatts of regenerative braking, which Formula E says can recover around half the energy needed for a race. (fiaformulae.com) (fia.com) Charging is getting a big step up too. Formula E says Gen4 will support 600 kilowatts of fast charging, which is far beyond the rate most public road-car chargers can deliver today and points to much shorter pit charging windows if the format uses them. (fiaformulae.com) (fia.com) The series is also pitching Gen4 as a sustainability showcase, not just a speed machine. The Fédération Internationale de l’Automobile says the car uses 100 percent recyclable bodywork materials and motors that are more than 90 percent efficient, with Formula E describing the package as almost 100 percent motor efficiency and 100 percent recyclable. (fia.com) (fiaformulae.com) Put together, Gen4 looks like Formula E’s clearest bet yet that electric performance will come from using energy smarter, not just carrying more of it. A 55 kilowatt-hour battery, 700 kilowatts of braking recovery, and permanent all-wheel drive add up to a car built less like a battery on wheels and more like a sprint machine that keeps refilling itself lap after lap.
