Porsche unveils 975 RSE Gen4 Formula E racing car

Porsche has revealed details regarding its Gen4 Formula E racing car, the 975 RSE, which is scheduled for competition in the 2026/2027 season. Named in honor of Porsche Motorsport’s 75th anniversary, the vehicle features a system maximum output of 816 ps (600 kW) and can accelerate from 0 to 100 km/h in 1.8 seconds.
