Porsche presents next gen Formula E race car

Porsche AG (Porsche) has marked a new chapter in all-electric motorsport with the presentation of its new 975 RSE, the brand's future Formula E race car.

This fourth gen car is said to deliver the biggest performance leap in electric motorsport to date, with a power output of 600kW, permanent all-wheel drive, new tyres, and a significant increase in downforce to enable much higher cornering speeds.

The 975 RSE's peak output of 600kW means that it is able to achieve a century sprint timing of 1.8 seconds

Since the 975 RSE produces 71% more peak power than its predecessor, the already highly efficient third gen powertrain saw a few tweaks. As Porsche only allowed the total weight of the parts package to increase by 5kg, and since more components for the new fourth gen drivetrain are being developed in-house. the brand managed to reduce the weight of many parts.

Said components that are being added include the DC/DC converter and the brake‑by‑wire system, further electronics and wiring looms, as well as control units for the hydraulic differentials. For cost reasons, the battery remains a standard-supplied component and may not be developed.

The 975 RSE's aerodynamic downforce significantly increases its grip on the track

The 975 RSE is expected to make its race debut in December later this year. Its name references the 75^th anniversary of Porsche Motorsport in 2026. For now, Porsche 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 optimisation of the software.

The Porsche customer team will also test the new car before the FIA homologates the specification in the Q4 2026. The 975 RSE first took to the track in November 2025 and had completed 1,860km of testing by early April 2026.
