The Porsche 718 Cayman GT4 ePerformance is the Mission R concept made real

Porsche begins testing its all-electric racer with hopes of a one-make race series to come

Porsche has created the 718 Cayman GT4 ePerformance to further test the components of the bonkers 1,073bhp Mission R concept, with the hope of one day creating an all-electric one-make race series.

The GT4 ePerformance uses the chassis of the current 718 Cayman GT4 Clubsport, but Porsche has designed some custom bodywork using natural fibre composite materials and recycled carbon fibres. The ePerformance is 14cm wider than the GT4 Clubsport too, with the full 900 volt, 80kWh battery and 1,073bhp twin electric motor setup from the Mission R plugged in. In total there are 6,000 parts designed from scratch, apparently. That’s some effort.

Looks like Porsche really wants this to be the car that launches its one-make electric race series. “We’re very excited about the response [to the GT4 ePerformance] because a one-make cup with electric racing cars would be an important addition to our existing customer racing programme,” said Matthias Scholz, Porsche’s boss of GT racing cars.

Porsche also says that, in terms of lap times and top speed, the all-wheel drive ePerformance is already equivalent to the 992-generation 911 GT3 Cup. Thanks to its direct oil cooling of the motors and battery, it can also run in race spec with 603bhp for 30 minutes – the same as a Carrera Cup race. Impressive. 

What do we think then, Internet? Excited to see where Porsche can take the 718 Cayman GT4 ePerformance? You can read our Mission R review by clicking these blue words.
