The 94mpg, 200mph, 770 hp Porsche 918 Spyder plug-in hybrid concept has made its UK public debut at the Goodwood Festival of Speed.
The Porsche 918 Spyder concept features a plug-in hybrid drivetrain with a V8 petrol engine and two electric motors and is estimated to return 94mpg based on the NEDC test.
Its V8 petrol engine delivers more than 500 hp, assisted by two electric motors with a total of at least 160 kW (218hp), with the production version due to offer over 770 hp combined.
The Porsche 918 Spyder is driven by a unique type of plug-in hybrid system. In the concept car, this 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, which won multiple victories in the Michelin Green X Challenge in the American Le Mans Series, the Le Mans Series and the 24 Hours of Le Mans.
Power transmission to the rear wheels is via a compact, seven-speed Porsche-Doppelkupplungsgetriebe (PDK). The 918 Spyder concept car complements this with 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 in excess of 16 miles in the NEDC test on purely electric power.
The 918 Spyder concept accelerates from a standing start to 62 mph in a maximum of 3.2 seconds and has a top speed of more than 199 mph. That means the Spyder will be able to lap the Nürburgring Nordschleife in less than seven minutes and 30 seconds – ahead of the Porsche Carrera GT (7 min: 32 s). The top speed on purely electric power is 94 mph. The combined total fuel consumption of the 918 Spyder in the NEDC (ECE-R 101) is anticipated to be 3.0 l/100 km (94 mpg), equating to CO 2
emissions of 70 g/km.
The design DNA of the concept car is derived from the Carrera GT and Porsche 917 race car, as well as the RS Spyder. Unlike the open top of the concept car, however, the production version of the two-seater will feature a manual roof system with removable roof panels that can be stowed in the front luggage compartment.
First prototypes of the 918 Spyder are now undergoing driving trials and the final specification is being further defined.
Production of the 918 Spyder – which will be offered in left-hand drive only – is scheduled to commence on September 18 2013 at the main Porsche factory in Stuttgart-Zuffenhausen, Germany. To ensure the exclusivity of the 918 Spyder, the two-seater is limited to no more than 918 units. Delivery of the first vehicles will commence in November 2013, priced from 645,000 Euro – subject to VAT and on-the-road charges.
