Presenting a high-performance mid-engined concept sports car with ultra-efficient, low-emission drive technology, Dr. Ing. h.c. F. Porsche AG, Stuttgart, is further increasing the Company’s competence in hybrid technology.
The Porsche 918 Spyder concept combines high-tech racing features and electro-mobility to offer a fascinating range of qualities: An emission level of just 70 grams CO2 per kilometre on fuel consumption of three litres/100 kilometres (equal to 94 mpg imp) truly outstanding even for an ultra-compact city car, on the one hand, combined with the performance of a super sports car and acceleration from a standstill to 100 km/h in just under 3.2 seconds, top speed of 320 km/h (198 mph) plus, and a lap time on the Nordschleife of Nürburgring in less than 7:30 minutes, faster than even the Porsche Carrera GT, on the other.
Porsche 918 Spyder - FeaturesEngine Power
This open two-seater is powered by a high-speed V8 developing more than 500 bhp and running at maximum speed engine of 9,200 rpm as well as electric motors on the front and rear axle with overall mechanical output of 218 bhp (160 kW).
The V8 combustion engine is a further development of the highly successful 3.4-litre power unit already featured in the RS Spyder racing car and positioned midship in front of the rear axle, giving the car the right set-up for supreme performance on the race track through its good balance.
Power is transmitted to the wheels by a seven-speed Porsche-Doppelkupplungs-getriebe also feeding the power of the electric drive system to the rear axle. The front-wheel electric drive powers the wheels through a firm 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 Porsche 918 Spyder kinetic energy is converted into electrical energy fed into the battery when applying the brakes, thus providing additional energy for fast and dynamic acceleration.
A button on the steering wheel allows the driver to choose among four different running modes: The E-Drive mode is for running the car under electric power alone, with a range of up to 25 km or 16 miles. In the Hybrid mode the Porsche 918 Spyder uses both the electric motors and the combustion engine as a function of driving conditions and requirements, offering a range from particularly fuel-efficient all the way to extra-powerful.
The Porsche 918 Spyder also comes with further innovative functions such as the Range Manager. After being activated in the Center Display, the Range Manager uses the map in the navigation system to present the remaining range the car is able to cover, naturally allowing the driver to influence that range through the appropriate choice of power and performance. In cities with environmental alert areas the Range Manager also states whether the driver is able to reach a certain destination on electric power alone.
Applying this information and using further info on the availability and location of special energy filling stations, the driver is then able to choose his personal style of driving as well as the right battery charge and filling strategy.
Offering a unique combination of extremely low fuel consumption, supreme performance and long electric range, the Porsche 918 Spyder represents an essential milestone in Porsche’s strategy on the way to genuine electro-mobility.
