Bitauto Original At the 2021 Munich International Auto Show, the Porsche Mission R concept car is a pure electric racing car, demonstrating its vision of providing customers with pure electric GT racing cars in the future. Since its public debut at this year’s Goodwood Festival of Speed, its test prototype 718 Cayman GT4 e-Performance has embarked on a global journey, participating in racing events around the world to test a series of innovative technology ideas.

The appearance of the 718 Cayman GT4 e-Performance retains many design elements of the Mission Rconcept concept car. The team from the Porsche Style department designed the appearance of the new car. The overall width of the car is 14 cm wider than the 718 Cayman GT4 Clubsport.

Compared with the 718 Cayman GT4 Clubsport, the 718 Cayman GT4 ePerformance has more expanded wheel arches. The increased space is conducive to installing wider 18-inch Michelin racing tires. In addition, the body eliminates the exterior rearview mirrors to better reduce air resistance for the vehicle.

The 718 Cayman GT4 e-Performance also adopts a window sealing design based on the 718 Cayman, and also has a new front enclosure and a huge fixed spoiler. It is worth noting that the body material of the new car is made of natural fiber composite materials.

Continuing the sustainable material features of the Mission R concept car, the natural fiber composite material used in the doors is made of flax, and recycled carbon fiber materials were also used for testing purposes. The tires are specially made by Michelin and contain 53% recycled materials. In addition, studded tires and tires suitable for hill climb racing are also available in sustainable versions.

The chassis of the vehicle comes from the 718 Cayman GT4 Clubsport, but as a brand-new electric racing car, approximately 6,000 components in the entire vehicle are newly designed. The entire motor and battery technology comes from the Porsche Mission R concept car, and has multiple mode options.

Porsche is committed to making the value chain and life cycle of all new cars on the market carbon neutral by 2030, by which time the proportion of pure electric new cars is expected to exceed 80%. Like the Mission R, the pure electric drive system of the 718 Cayman GT4 ePerformance uses permanent magnet synchronous motors located on the front and rear axles respectively, turning it into a full-time four-wheel-drive racing car that can output up to 800kW (1088PS).

In simulation races, 450 kW (612 PS) of power can be sustained30 minutes, equivalent to the main match of the Carrera Cup. Porsche has developed a direct oil cooling system for the electric motor and battery pack, which greatly improves heat dissipation efficiency and effectively avoids system heat exhaustion. In terms of lap times and top speed, the GT4 e-Performance is roughly on par with the current 992-generation 911 GT3 Cup.

As a racing car, the 718 Cayman GT4 e-Performance follows the same regulations and rules as Porsche production cars. Based on the standards of Formula E, high-voltage safety and collision management are strictly managed. Even in the event of a collision, the connection between the battery and the vehicle and high-voltage consumers will be automatically disconnected to ensure that there is no voltage.

In addition to the powerful power, the application of 900 V technology allows the battery to be charged at full power, charging the battery from 5% to 80% in only 15 minutes. The full-time adjustable four-wheel drive equipped with the 718 Cayman GT4 e-Performance can recuperate energy on both axles with a rate of up to 50%, further improving overall energy efficiency.

Oliver Schwab, project manager for the 718 Cayman GT4 e-Performance Test Tour, said: “It is very important to make motorsport relevant to the future, so we want to introduce electrification into customer racing and continue to develop it.” Porsche All this is done not only to develop a successful racing car, but also to develop a successful racing entertainment platform for customers. ”

With the help of the test trip, 718 Cayman GT4 ePerformance will create a new pure electric racing path for Porsche customer racing. At the same time, it will also collect extensive global information along the way to explore and explore the possibilities of related racing activities, bringing together all parties.
