Porsche 918 Spyder supercar

It accelerates from a standing start to 100 km/h in 3.2 seconds and has a top speed of more than 320km/h. That means the Spyder will be able to lap the Nurburgring Nordschleife in less than seven minutes and 30 seconds - ahead of the Porsche Carrera GT at seven minutes and 32 seconds. The top speed on purely electric power is 150 km/h. A unique type of plug-in hybrid system drives the 918 Spyder. It comprises a high-revving V8 engine with a displacement exceeding 4.0-litres and an output of more than 500 hp. The mid-engine power unit is based on the racing engine of the successful Porsche RS Spyder.

Power transmission to the rear wheels is via a compact, seven-speed transmission. This is complemented by two electric motors - one each on the front and rear axle - with a joint mechanical output of at least 160 kW (218 hp). This configuration offers an innovative, variable all-wheel drive with independent control of the propulsion force on both axles. The energy storage unit is a liquid-cooled lithium-ion battery that can be charged from a conventional domestic power socket, delivering a range of just 25km on purely electric power.
