Under the skin of the Mission R
It didn’t even have its striking shell when development engineer and racing driver Lars Kern started testing the future: the technology of the Mission R. The concept could be the basis of the first all-electric Porsche racer for the customer racing milieu.
It garnered a lot of attention at the International Motor Show (IAA) in Munich in early September: the Mission R. The all-electric racing car is, for now, just a vision. An idea of what the future design language might look like –demonstrated by the concept car for an all-electric customer racing vehicle from Porsche.
The Mission R, however, is already a capable racer.
Implementation of the Porsche strategy
Beneath its shell, the car represents the fulfilment of Porsche’s strategy on sustainability and social responsibility. Porsche rarely shows such futuristic concept cars. Take the Boxster: the original concept was presented in Detroit in 1993. The 918 Spyder concept car followed in 2010, this time in Geneva. “These are jobs with massive deadline pressure,” he admits, “yet at the same time they’re engineers’ dreams come true that start with a blank sheet of paper.” There’s no model for the Mission R. It is the model.
Thinking it all the way through
For Porsche’s standards, it is not enough just to build a rolling chassis that merely gives shape to a vision from the design department. The spirit of Weissach demands performance in concept cars as well. During the creation process, every step of the computer-aided design (CAD) process is carried out with the same attention to quality as if it were a pre-production vehicle.
With a target weight of less than 1,500 kilograms, the sports car should manage the sprint from 0 to 100 km/h in less than 2.5 seconds.
Direct cooling of the stator
Thanks to the direct cooling of the stator – the stationary element of the electric machine in which the rotor rotates – the units deliver exceptionally high continuous power. The futuristic racing car makes do with just one oil cooling circuit and without a single drop of water. The direct oil cooling of the high-voltage battery is based on an innovation developed for the three-time Le Mans winner, the Porsche 919 Hybrid.
“At the same time, we did our utmost to leverage the last bit of lightweight potential in every detail,” says Behr. The additional braking power during recuperation made it possible to shave 12 kg off the braking system. The composite outer skin is not just feather-light, but also sustainable: it consists mainly of natural fibre, supplemented by carbon fibre components.
Weissach is renowned for excellent engineering, and also for craftsmanship. The chassis of the secret prototype was built in Flacht, in the racing department. It later moved within Weissach to Building 100 – a high-security facility beneath the studio of Style Porsche.
