Porsche 718 Cayman GT4 ePerformance revealed as all-electric Mission R test vehicle

Porsche has announced that it is testing new technology in its 718 Cayman GT4 ePerformance vehicle. The 718 serves as a test vehicle for Porsche's Misson R all-electric concept racing car, revealed last year at IAA Mobility.

The chassis of the 718 Cayman GT4 Clubsport is combined with an all-electric motor and battery to provide up to 735 kW (1,000 hp) output in qualification mode. The car has been tested in simulation races, which saw a 450 kW (612 hp) output for 30 minutes, which is the duration of a Carrera Cup race. The peak output of the car is 800 kW (1,088 hp).

In testing, the 718 Cayman GT4 ePerformance matched the current 992-generation 911 GT3 Cup for lap times and top speed. The EV's battery has 900 V technology and can charge from 5 to 80% in 15 minutes. The car has all-wheel drive thanks to a permanently excited synchronous machine (PESM) on the front and rear axles.

The Porsche 718 Cayman GT4 ePerformance will debut at the Goodwood Festival of Speed this June, taking part in the 1.9 km (~1.2 mile) hill-climb event. It will get another outing at Porsche's Leipzig factory to celebrate its 20th anniversary in August, with a world tour beginning in 2023.

This project is helping Porsche reach its goal of being CO2 neutral across its whole business by 2030, including the lifecycle of any new vehicles sold. At this point, the company also plans for EVs to make up over 80% of its sales.
