While the introduction of the third generation of Formula E cars will be delayed a year due to Coronavirus, the new specs provide an indication the sport is driving towards. Starting in 2023, Gen 3 Formula E cars promise to be lighter, deliver more power from smaller batteries, more regenerative braking, and, if the technology is advanced enough, 600kW ultra fast charging (UFC) during pitstops. And there are other technological advancements the sport is pushing towards.

First off, the Gen3 spec car will have a qualifying output of 350kw, that’s 100kw more than the current race car, a gain of 134hp to 469hp. This pushes the car power output well up the FIA ladder, more than F3 cars, not quite at the level of F2. Although the FE car’s weight is higher.

For the battery partner, the task will be to build a new battery, slightly smaller in capacity to the current spec, but with a much-reduced weight. The FE rules set out the maximum weight for the cells inside the battery, in the current Gen2 battery this is 284kg, but will reduce to 180kg, with the related parts around the cells also slimmed, the battery aims to be 120kg lighter, forming most of the weight loss from the new car.

As mentioned above, the battery loses a few kwh from its capacity which will help reduce the weight, but this is only a 5.5% reduction in capacity to 51kwh. But Formula E has an exciting way to add that lost energy back into the car during the race, mid race recharging pitstops!

Plans are set for a 30 second recharge pitstop mid-race, at a rate of 600kw which would top up the battery and replace the lost 4kwh from its spec…
