Porsche have showcased an electric vehicle concept at the Electric Vehicle Symposium in Stuttgart. The Cayman e-volution is a research vehicle with a charging voltage of 800 volts that accelerates from zero to 100 km/h in 3.3 seconds and offers a range of 200 kilometres. Unfortunately, no powertrain details have been released. The vehicle will not go into series production, but does give an early indication of just how sporty Porsche believes e-mobility can be.

The Cayman e-volution also hints at what is to come in 2019, when Porsche will bring its first purely electric sports car, the Mission E, into production. The Mission E will be capable of covering a range of over 500 kilometres, and will be able to charge its batteries to 80 per cent within just 15 minutes.

With Porsche Turbo Charging, the sports car manufacturer is also showcasing its first ever accumulator-based fast charging system, which is capable of achieving a charging capacity of up to 320 kW per vehicle or twice 160 kW. The system is a collaborative development between Porsche Engineering and ADS-TEC, and is particularly suitable for use in areas where the distribution system is subject to power limitations.

The system is to be used as a supplement to high-power fast charging network with medium voltage connection. One of these networks will be built on major European traffic routes by 2020 in a joint venture between Porsche, Audi, BMW, Daimler and Ford.
