Formula E Gen4


Article by Tobias Selerit

4th generation Formula E cars take a big step in power and speed. Compared to Gen 3 Evo cars, the Gen4 cars are at least 5 seconds per lap faster on street tracks. In qualifying mode, even 10 seconds faster. That is a huge jump. Top speed reaches 208 mph / 335 km/h.

Gen3 pre-Evo cars already had two motors, but the front motor was used only for electricity generation under braking. Gen3 Evo and Gen4 cars have 4-wheel-drive.

With Gen4 car, it is possible to use two aerodynamic setups: for efficiency reasons low drag setup is used in the race, and high downforce setup in the qualifying session. With Gen4 came a 150% downforce increase!

The capacity of the battery is 51 kWh. Charging power peaks at 600 kW. During the 34 seconds mandatory pit stop, around 4 kWh is charged into the battery. Under braking, each motor can recover up to 350 kW. In theory, that is 700 kW of energy going back into the battery. Up to 50% of the energy needed in the race is generated during braking.

The Gen4 car is very long at 218″ / 5.54 m. This racing car is 6″ / 15 cm longer than the BMW i7 luxury limousine with its long wheelbase!

Development rules are strict. All teams get the chassis and body from Spark Racing Technology. Podium Advanced Technologies supplies the battery. It contains no rare earth minerals.

Manufacturers build key performance parts. This includes the electric motor, electronics, brake-by-wire system, software, gearbox, differential, drive shafts, and cooling.

The Formula E grid is strong thanks to brands like Porsche, Jaguar, Mahindra, Nissan, Lola, and the Stellantis group.

Formula E series was created already in 2014. Gen4 cars were built for the 13th season starting in December 2026.
