One of the star attractions at the Geneva motor show is Porsche’s 918 Spyder hybrid concept. The sportscar concept is powered by a mid-engined, 373 kW V8 engine, with two electric motors driving each axle to supply an additional 160 kW.
Power is distributed to the wheels via Porsche’s seven-speed PDK double clutch transmission. The 918 Spyder hybrid can accelerate from 0 – 100 km/h in just under 3.2 seconds, it has a top speed of 320 km/h and boasts a Nürburgring Nordschleife lap time of less than 7:30 minutes – faster than the Porsche Carrera GT.
Michael Macht, president and chief executive officer of Porsche, stated during the unveiling of this sports car, that Porsche has never shown a concept car that it hasn’t put into production. So that more or less tells us that we will be seeing this car in showrooms in the near future.
The 918 Spyder is one of three Porsche models with hybrid drive making their world debut at the 2010 Geneva Motor Show. This trio is made up of the new Cayenne S Hybrid SUV with parallel full-hybrid drive, the 911 GT3 R Hybrid racing car with electric drive on the front axle and a flywheel mass battery, and the two-seater high-performance 918 Spyder mid-engined sports car with plug-in hybrid technology.
Porsche Press Release
The 918 Spyder prototype combines high-tech racing features and electro-mobility to offer a fascinating range of qualities: An emission level of just 70 g/km of CO2 on fuel consumption of 3 l/100km is 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.
The 918 Spyder is one of three Porsche models with hybrid drive making their world debut at the 2010 Geneva Motor Show. This trio – made up of Porsche’s new Cayenne S Hybrid SUV with parallel full-hybrid drive, the 911 GT3 R Hybrid racing car with electric drive on the front axle and a flywheel mass battery, and the two-seater high-performance 918 Spyder mid-engined sports car with plug-in hybrid – clearly demonstrates not only the great bandwidth of this new drive technology, but also the innovative power of Porsche as a genuine pioneer in hybrid drive.
This open two-seater is powered by a high-speed V8 already featured in the RS Spyder racing car, 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).
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.
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 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 Sport Hybrid mode uses both drive systems, but with the focus on performance. Most of the drive power goes to the rear wheels, with Torque Vectoring serving to additionally improve the car’s driving dynamics.
In the Race Hybrid mode the drive systems are focused on pure performance with the highest standard of driving dynamics on the track, running at the limit to their power and dynamic output. With the battery sufficiently charged, a push-to-pass button feeds in additional electrical power (E-Boost), for example when overtaking or for even better performance.
Reminiscent of highly successful, legendary racing cars such as the Porsche 917 Le Mans and the current Porsche RS Spyder, the 918 Spyder with its design concept so typical of Porsche arouses powerful emotions. The combination of racing car dimensions, clearly structured design with perfectly balanced surfaces, and innovative details all round creates an overall pattern of aesthetic, perfectly balanced harmony in design full of power and dynamics.
The control units relevant to the driver are concentrated in particular on the three-spoke multifunction sports steering wheel, while the variable driving modes, again so typical of Porsche, are supplemented by a map switch enabling the driver to call up various drive programs and serving as the push-to-pass button for E-boosting, for example when overtaking.
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.
