The test vehicle is an intermediate stage on the road to the Mission R study car unveiled in 2021: Porsche installed the purely electric powertrain components in the chassis of the 718 Cayman GT4 Clubsport racing car for testing.

Initial experience shows that in terms of lap time and top speed, the electric model is at the same level as the current (992) Porsche 911 GT3 Cup.

Porsche, which aims to make its entire business carbon-neutral by 2030 and to equip 80 percent of its cars with a purely electric powertrain, will want to launch its electric racing car in the first round in a brand cup.

Both axles of the 718 Cayman GT4 ePerformance, like the 2021 Mission R study car, are powered by a separate electric motor. The oil-cooled electric motors have a total output of up to 800 kW (1088 hp) and, although this is only available for a short time (eg timing circuit), 612 hp can be maintained for up to 30 minutes – ie a complete run – thanks to optimal heat management. The 900 V battery can be charged from 5 to 80 percent in 15 minutes.

The 718 Cayman GT4 ePerformance is 14 inches wider than the underlying 718 Cayman GT4 Clubsport; the wider wheel drums spin 18-inch Michelin racing tires made largely of recycled materials.

About 6,000 brand new parts have been developed for the prototype. The body is made of composite elements made of natural fibers; they can be manufactured more clearly than composites with similar properties but containing synthetic fibers. Porsche is also experimenting with recycled carbon fiber material.

The Porsche 718 Cayman GT4 ePerformance prototype will first be seen live at the Goodwood Speed ​​Festival in late June and will be unveiled at a ceremony to mark the 20th anniversary of Porsche’s Leipzig plant a month later. The two 718 Cayman GT4 ePerformance prototypes will then travel around Europe for potential customers to learn about the technology, followed by North America from 2023 and Asia from 2024 onwards.
