Porsche 918 Spyder Concept

The 918 Spyder will feature a high revving 500-plus horsepower V8 engine assisted by two electric motors with a total of at least 218 horsepower, yet Porsche estimates it will consume only 3.0 L/100 km based on the New European Driving Cycle (NEDC). Official EPA fuel economy figures or estimates will be announced just before the first customer cars begin arriving in the United States near the end of 2013.

To ensure the 918 Spyder’s worldwide exclusivity, Porsche will produce no more than 918 examples. Start of production at Porsche’s famed factory in Stuttgart-Zuffenhausen is planned for Sept. 18, 2013 (9/18), and the U.S. base manufacturer’s suggested retail price is $845,000 (excluding destination and handling charges).

The 918 Spyder will be powered by a unique plug-in hybrid system that will include a high-revving, mid-mounted V8 engine with capacity of more than 4.0 liters and producing at least 500 horsepower. The engine will be based on the Porsche RS Spyder racing engine that demonstrated its impressive performance and efficiency through multiple Michelin Green X Challenge victories in the American Le Mans Series, the Le Mans Series and the 24 Hours of Le Mans. Power will be transferred to the rear wheels via Porsche’s compact, seven-speed Porsche-Doppelkupplung (PDK) double-clutch gearbox.

Two electric motors – one each on the front and rear axles – together will provide approximately 218 additional horsepower. This configuration also will offer an innovative, variable all-wheel drive system with independent control of the drive forces on both axles. Electrical energy will be stored in a liquid- cooled lithium-ion battery that can be recharged from a standard household outlet. Electric-only driving range is expected to be more than 16 miles on the NEDC. Recharge time will depend on each country’s electrical power network, but charging is expected to take about seven hours at 110V/10A in the United States. A quick-charge option is being evaluated to further reduce charging times.
