Formula E revealed its new “GEN4” vehicle for next season, with a huge step up in performance – the series’ biggest advancement yet.
Formula E is the FIA’s biggest top-level racing series, having started all the way back in 2014 and hosting open-wheel all-electric races all around the world.
It started with somewhat modest performing vehicles, with around 250hp and a top speed of 140mph. The cars also had relatively small 28kWh batteries, which meant they couldn’t complete a full race – drivers would actually get out and swap into a new car with a fully charged battery halfway through, then continue the race.
In Gen 2, things got a little less silly, and batteries got better enough to allow for a full race distance. Power went up and the cars got faster around the track.
Gen 3 was another improvement, with a more angular look and an innovative braking system which removed the front friction brakes entirely, instead using a front motor for more regenerative braking. Later on in the car’s lifecycle, that motor was activated for drive power, not just regen, and it became the only all-wheel drive open-wheel racecar. But, it could only be used in qualifying or specific circumstances within a race.
Now, with the Gen 4 car, Formula E is throwing caution to the wind and going all-time all-wheel drive, which no other open-wheel racing series does (it’s been tried a few times, but never stuck). There are other types of vehicles that race with all-wheel drive, but no other open-wheel single-seaters.
But that’s not all, there have also been a lot of spec improvements from the new vehicle.
Max power improves from 350kW to a whopping 600kW (805hp) – a near doubling. The Gen 3 cars were limited to 300kW in race mode, but the Gen 4 will have that boosted to 450kW (603hp). Max 600kW will be available in qualifying and in “attack mode,” a temporary boost that drivers can activate during the race.
With the higher performance, Formula E will offer new downforce packages. In the beginning, Formula E cars didn’t quite travel fast enough for downforce to matter a whole lot (especially since it also harms efficiency), but now that the series is getting more powerful, there will be more options available to optimize bodywork for certain racetracks.
All that fits into a package thats just 1,012kg (2,230lbs), and accelerates from 0-60 in 1.8 seconds. That’s about 30% faster than an F1 car can make the same sprint – though, admittedly, racecars only go 0-60 one time per race. But it’s still useful to zip out of a turn real quick.
All-wheel drive will also help corner exit speed, as it allows drivers to put the power down earlier without spinning out. Another new feature on the Gen 4 cars which will enhance driveability is the addition of anti-lock brakes and traction control – features that aren’t seen on most racecars (and, to be quite honest, I’m not a fan of this – makes the car too easy to drive, and numbs the racing).
More importantly, in initial testing, a Gen 4 car was clocked at 211mph, which is, uh, fast as hell:
Regenerative braking capacity is boosted to 700kW from the previous 600kW, so more energy will be recaptured throughout the race, enhancing efficiency. That might also translate into faster mid-race charging speeds, as Formula E finally got its mid-race charging plans working this last season with a feature it calls “pit boost.”
Formula E says that the goal of this car was to build “the world’s most sustainable race car”, and says that 100% of the materials used in its construction are recyclable, and at least 20% of the materials used in it are recycled content, which is double the amount of the outgoing generation.
The car will start racing next season, in late 2026. Formula E’s 12th season, the last season of the Gen 3 cars, starts on December 6 in São Paulo.
Electrek’s Take
It’s exciting to see the advancements in electric racing, and having such a huge jump in power from one generation to another is quite impressive. Remember, the first FE cars in 2014 had just 250hp, and now we’re here at 805hp – more than three times as much as where we started. For comparison, today’s F1 cars have around 1,000 horsepower.
I’m less enthused about the addition of driver’s aids. Traction control and anti-lock braking take a lot of the skill out of driving, make races less unpredictable, and restrict performance of the vehicles as compared to a perfectly-driven car (well, traction control does at least – because it cuts motor power when it detects wheel slippage).
These aids are great for road cars and unpracticed drivers, but for professional drivers seeking to extract every tiny bit of performance, and to do so in an exciting way that is entertaining to watch, I think these are a big step down. We hope they reconsider this, or add some sort of restriction on the use of the systems.
Nevertheless, it’s always exciting to see what these new cars can do after each upgrade, and this one seems like more of a doozy than ever. We’re looking forward to seeing it all at the end of 2026.
