During the 2015 Frankfurt Motor Show, Porsche introduced a concept version of Mission E - the first all-electrically powered four-seat in Porsche's history. What does that mean for the Tesla S' future?
According to Porsche, the concept sports car displays their unmistakable emotional design paired with excellent performance and the forwardthinking practicality of the first 800-volt drive system.
This fascinating sports car with four doors and four single seats is powered by two permanently-excited synchronous motors (PSM) – similar to those used in this year's Le Mans victor, the 919 hybrid – accelerate the sports car and recover braking energy. Together the two motors produce over 600 hp, and they propel the Mission E to a speed of 100 km/h in less than 3.5 seconds and to 200 km/h in under twelve seconds. Unlike today's electric drive systems, they can develop their full power even after multiple accelerations at short intervals.
The need-based all-wheel drive system with Porsche Torque Vectoring – which automatically distributes torque to the individual wheels – transfers the drive system's power to the road, and all-wheel steering gives precise, sporty steering in the desired direction. This makes the Mission E fit for the circuit race track; its lap time on the North Loop of the Nürburgring is under the eight-minute mark.
Significantly boosting performance and a sports car feeling was achieved by developing a lightweight concept with optimal weight distribution and a low centre of gravity. The lithium-ion battery mounted in the car's underbody runs the whole length between the front and rear axles, which distributes its weight to the two drive axles uniformly, resulting in exceptionally good balance. The body as a whole is made up of a functional mix of aluminium, steel and carbon fibre reinforced polymer.
The driving range of the Mission E with a fully charged ion-lithium battery is estimated at over 500 kilometers, but in just 15 minutes you will be able to provide enough charge from a quick charge station to ensure a further 80 per cent of the total range. Reducing charging time is the innovative 800-volts battery charging system Porsche Turbo Charging, which is twice as more effective as today's electric vehicles that operate at 400 volts. You can also charge your battery by connecting it to a conventional 400-volt quick-charging station, or it can be replenished at home via an inductive wireless charging device in your garage.
Porsche says Emission E paves the way to future models. The interior emphasizes the benefits of a deeply generous driver's space with OLED technology and 3D displays. The driver as well as his wingman can enjoy the holographic display and control the infotainment systems (media, navigation, climate control, contacts and vehicle) completely touch-free.
