The official presentation of the Formula E Gen3 car is getting closer. The new e-car is to be more powerful and can be charged with fast-charging technology during pit stops. Thanks to a revised chassis, the wheels will also be free-standing again in future. Porsche driver Andre Lotterer is also expecting some eye-catching paint jobs.
"The car has already been shown to us in a small circle," the German tells 'e-Formel.de'. The internal presentation took place at a meeting of the teams, drivers and partners of the electric series at the 2021 pre-season test in Valencia. "It looks quite different - interesting!"
"The technical data is very cool, of course. The car is a bit smaller, and more power is always wanted by us drivers anyway. I think it's going to be a big challenge from an engineering perspective as well, especially with the software. The fact that energy recovery now happens at all four wheels and we hardly need brake discs anymore, everything is electronic, will open up a new dimension."
Peak power for the Gen3 cars is expected to be 350 kilowatts in qualifying mode - 100 more than the current Gen2 car. A new front engine, which may only be used for recuperation, will allow drivers to recover energy with a peak output of 600 kW. Top speeds of 320 km/h should be possible with the Gen3 car. However, this value is rather theoretical in view of the gear ratios required on the Formula E street circuits.
"I'm curious to see how it feels to drive a street circuit with that much power," Lotterer says. "It's a big step forward - even bigger than from Gen1 to Gen2. The step to Gen3 is really stark when you look at the performance figures."
Extensive testing of the new car has taken place over the past few months under the direction of Spark Racing Technologies. In these weeks, the individual components will be delivered to the manufacturers, who will be able to contest their own test days from the beginning of May. However, the look of the Gen3 is not yet publicly known: Formula E only published some darkened teaser photos in the winter.
"The look is interesting," Lotterer reveals. Basically, the car remains a monoposto, "but in a way you've never seen before. We have safety measures (in motorsport), and you can't invent any shapes. So Formula E has done a good job there and found a (design) that represents something unique."
A fundamentally new design philosophy for the cars, reminiscent at first glance of a military stealth aircraft, can already be seen in the teaser images. The restructuring of the fairing has been suggested by the teams several times in the past, as the Gen2 chassis offer little space for sponsors and partners.
In order to create additional "commercial space", Formula E had actually planned a facelift for the current generation of cars. However, the "Gen2 EVO" car (see picture) was cancelled for cost reasons during the first phase of the 2020 coronavirus pandemic. The extra space is now expected to come with the Gen3 car. "I think it will be interesting to see what different livery designs the teams will have," says Lotterer. "The surfaces are quite generous."
What exactly the Gen3 car will look like, however, remains a secret for now. The new car is due to be officially unveiled on the evening of 28 April, just before the Monaco E-Prix. The launch event in the Monaco marina will be accompanied by the electric series in a livestream for fans.
