A new chapter in all-electric motorsport: with the h.c. F. Porsche AG presents its future Formula E race car. The single-seater complies with the regulations for the fourth 975 RSE, Dr. Ing.
Highlights
- New Porsche single-seater to date975 RSE succeeds the most successful
- Even stronger acceleration and a top speed exceeding 330 km/h
- Significant development progress since the introduction of Formula E in 2014
- The so-called tires and significantly increased downforce bring Formula E into the slipstream of the fastest single-seater race cars worldwide.GEN4 delivers the biggest performance leap in electric motorsport to date: 600 kW (816 PS) of power, permanent all-wheel drive
“The Porsche Motorsport. “When the championship started in 2014, every driver needed two cars per race. One battery alone was not enough to cover the full race distance. Those days are long gone. Since 2024, we have been developing a race car that puts us on the level of Formula 2 cars. EVs are not only catching up with the standards we are used to; their strengths are becoming increasingly evident – on the track and on the road.”GEN4 shows how far electric vehicles have evolved,” says Thomas Laudenbach, Vice President
More downforce for greater performance
For the first time, aerodynamic downforce significantly increases the grip of tires and permanent all-wheel drive, this enables much higher cornering speeds. Olivier Champenois, Technical Project Leader Formula E at ‑downforce package with reduced drag for the races, and a high‑downforce package for qualifying, where energy consumption isn’t relevant. We are talking about up to 150 percent more downforce compared to the GEN3 Evo. ”Porsche Motorsport: “Within roughly a decade, Formula E has become so fast that aerodynamic downforce is now a necessity. However, downforce always comes with drag and increases energy consumption. To maintain a strong focus on efficiency, we use two different aero packages with distinct bodywork components: a lowFormula E cars. Together with new
Porsche in-house developments: lighter, more durable, more cost-efficient
Already in the current including potential in terms of weight, durability and costs – similar to EVs for the road,” says Champenois. “The kilogrammes.”Porsche, the highly efficient GEN3 Evo-generation Formula E 975 RSE produces 71 percent more peak power than its predecessor. At the same time, we were able to reduce the weight of many parts. Although we are developing more components in-house for GEN4 than for GEN3, the total weight of our parts package was only allowed to increase by 5

Aerodynamics
Two packages with aerodynamic elements for higher and lower downforce and drag
Key standard components
DC/DC converter, pulse inverter, electric motor, gearbox, electronics and wiring looms, front and rear differentials including control units, drive shafts and further drivetrain components on the rear axle, as well as cooling, carrier and suspension components on the rear axle, brake-by-wire system, operating software
Same concept, faster racing
Florian Modlinger, Director Factory Motorsport Formula E: “The concept remains the same: the regulations force us to maximize the efficiency of our cars in every respect – because that makes us relevant for the road. The races should become even more attractive, as the new cars are considerably faster. The acceleration is impressive, and we expect top speeds of up to 335 km/h. I’m very curious to see how the fans will react.”
The Porsche 975 RSE follows on from the current 99X Electric
For now, optimization of the software. The Porsche customer team will also test the new car before the FIA homologates the specification in the autumn. The kilometres by early April. Porsche presents the new vehicle as the reigning Porsche Motorsport has until October to develop its most extensive hardware package for Formula E to date as far as possible. After that, the focus will shift to the continuous Formula E Manufacturers’ World Champion.975 RSE first took to the track in November 2025 and had completed 1,860 test
Further comments on the new car
Pascal Wehrlein, Porsche factory driver:
“The new Porsche 975 RSE is a really cool race car. The GEN4 is extremely fast and great fun for us drivers. I believe it will be a real eye-opener for many fans and critics. ”
Nico Müller, Porsche factory driver:
“The 975 RSE and its competitors are a massive step forward for the sport. I’m a big fan of how aggressively you can drive. Especially in qualifying, when everyone is pushing to the limit, it should be spectacular – particularly because of the strong acceleration out of the corners. I’m glad I was involved in the simulator work from the beginning. Pascal and I share the testing duties. ”
