Porsche has begun testing the electric version of the Porsche 718 Cayman GT4 race car.
Last year at IAA MOBILITY Porsche set out a vision for the all-electric racing future of the GT with the Mission R, however the Cayman GT4 ePerformance is making this a reality by taking components from the Mission R car.
The Porsche 718 Cayman GT4 ePerformance is all-wheel drive and uses the chassis of the 718 Cayman GT4 Clubsport.
The technology of the electric motor and the battery comes from the IAA concept study, which in qualifying mode means a maximum power of 735 kW.
In simulation races, it could run up to 450 kW in 30 minutes, i.e. duration of the Carrera Cup race. In terms of lap time and top speed, the 718 Cayman GT4 ePerformance is on par with the performance of the current generation 992 911 GT3 Cup.
The 718 Cayman GT4 ePerformance is based on a synchronous machine with constant excitation (PESM) on the front and rear axles. Together, they turn the race car into an all-wheel drive and can provide peak power of up to 800 kW.
“With Mission R, we have shown how Porsche anticipates sustainable customer racing in the future,” said Matthias Scholz, GT Racing Car Project Manager.
“The 718 Cayman GT4 ePerformance now demonstrates that this vision works impressively on the racetrack.
“We are very excited about the reaction because the cup of one production with electric racing cars will be an important addition to our existing racing program for customers.”
The German sports car brand aims to ensure that the life cycle of each new car is carbon-neutral by 2030, when 80% of all cars sold are expected to be electric.
GT4 ePerformance project manager Bjorn Forster explained how cooling electronic engines and batteries developed by Porsche counteracts thermal power reduction.
“The integration of oil cooling has significantly affected the concept of the car,” Forster said. “With experts in aerodynamics and thermodynamics, as well as specialists in high-voltage and body-operated machines.
“The development team has created an architecture to use the full potential of rechargeable batteries for the first time, as there are no thermal dips. Thus, the power in racing mode remains constant for half an hour.
A race car, thanks to 900 volt technology, can charge from five to 80 percent in about 15 minutes.
The race car is 14 inches wider than the standard 718 Cayman GT4 Clubsport.
In total, about 6,000 parts were developed from scratch.
Porsche is pleased that the body is made of composite materials made of natural fibers, including that which generates fewer emissions than the production of comparable synthetic materials.
Flared wings give more room for wide 18-inch racing tires from Michelin.
The Porsche 718 Cayman GT4 ePerformance will debut at this year’s Goodwood Speed Festival, which runs June 23-26.
