Porsche has begun real-world testing of know-how from its Mission R electrical race automobile idea in a Cayman-based prototype.
The Porsche 718 Cayman GT4 ePerformance combines the physique shell from the 718 Cayman GT4 Clubsport racer with the Mission R’s powertrain and battery tech, Porsche defined Monday in a press launch.
Meaning the Cayman GT4 ePerformance has an electrical motor powering every axle, with the identical 1,073-hp most output because the Mission R. Nonetheless, engineers plan to dial that again a bit for many use instances. Porsche says the electrical Cayman produces 985 hp in simulated qualifying trim, and 603 hp in simulated race trim.

On the decrease race energy degree, the automobile has sufficient battery cost to run for half-hour, the identical size as a Carrera Cup race, Porsche claims. The automaker additionally says the Cayman GT4 ePerformance can match a present 911 GT3 Cup automobile in lap instances and velocity.
An oil-cooling system for the battery pack and motors helps tackle heat-related efficiency losses so energy stays fixed for the focused half-hour racing stint, in line with Porsche. When it is time to recharge, a 900-volt electrical structure permits for a 5% to 80% cost in about quarter-hour, the automaker claims.
A design workforce led by Grant Larson—designer of the unique Porsche Boxster idea—additionally made some modifications to the bodywork. The electrical racer is 5.5 inches wider than an ordinary 718 Cayman GT4 Clubsport, due to wider fender flares that cowl 18-inch Michelin racing tires. The physique panels and the tires incorporate renewable supplies, together with natural-fiber composites and recycled carbon fiber for the bodywork.

The Cayman GT4 ePerformance will make its public debut on the 2022 Goodwood Competition of Velocity, scheduled for June 23-26. It can then head to Porsche’s Leipzig, Germany, manufacturing unit in August for that facility’s twentieth anniversary, adopted by a tour of European nations. A pair of the prototypes will then journey to North America in 2023 and Asia in 2024.
By that point, Porsche could also be prepared to point out a manufacturing electrical 718, in line with a 2021 Automobile and Driver report. The automaker estimates that by 2030 greater than 80% of its gross sales will probably be EVs. It is investing in battery tech and manufacturing to arrange for that.
