“In simulated racing, a steady 450 kW (612 PS) is available for 30 minutes, i.e. the duration of a Carrera Cup race. In terms of lap times and top speed, the 718 Cayman GT4 ePerformance is on par with the performance of the current 992-generation 911 GT3 Cup,” Porsche’s announcement said.
“The 718 Cayman GT4 ePerformance now demonstrates that this vision works impressively on the racetrack,” said Porsche GT racing vehicle project manager Matthias Scholz. “We’re very excited about the response, because a one-make cup with electric racing cars would be an important addition to our existing customer racing program.”
Apart from employing all-wheel drive rather than the standard GT4’s RWD setup, the GT4 ePerformance has quite a bit in common with the existing 718 Cayman GT4 Clubsport. The powertrain was lifted in its entirety from the Mission R (shown above), which can produce upwards of 1,000 horsepower in its most performance-friendly setting. The GT4 ePerformance prototype is about 5½ inches (14 centimeters) wider than the Clubsport, Porsche says, and required the fabrication of approximately 6,000 unique new parts.
