Re: Porsche surprise in Geneva - concept of CGT succesor ?
Great to see the Porsche 918 Spyder's V8 motor is based on the race-developed 3.4-litre engine in the RS Spyder, generating over 500bhp with a 9,200rpm red-line...
Innovative powertrain combines race-bred V8 engine with electric drive
"This open two-seater is powered by a high-revving V8 developing more than 500 horsepower and a maximum engine speed of 9,200 rpm – as well as electric motors on the front and rear axle with overall mechanical output of 218 horsepower (160 kW).
The V8 combustion engine is the next step in the evolution of the highly successful 3.4-liter power unit already featured in the RS Spyder racing car and positioned mid-ship, in front of the rear axle, giving the car excellent balance and the right set-up for supreme performance on the race track.
Power is transmitted to the wheels by a seven-speed Porsche-Doppelkupplungsgetriebe (PDK) transmission that feeds the power of the electric drive system to the rear axle. The front-wheel electric drive powers the wheels through a fixed transmission ratio.
The energy reservoir is a fluid-cooled lithium-ion battery positioned behind the passenger cell. The big advantage of a plug-in hybrid is that the battery can be charged on the regular electrical network. A further point is that the car's kinetic energy is converted into electrical energy fed into the battery when applying the brakes, thus providing additional energy for fast and dynamic acceleration."
...look forward to seeing Chris Harris drive the new Porsche 918 Spyder!
