A race car concept is present at 2011 Detroit Auto Show, is a two-seat mid-engined coupe, and according to Porsche, it demonstrates what happens when the technology fitted in the 911 GT3 R Hybrid race car and the design of the 918 Spyder concept are combined together.

It based motorsports version of the 918 Spyder concept car gets a V8 engine based on the RS Spyder race car’s 3.4-liter unit tuned to deliver 563HP at 10,300 rpm, and is linked to a six-speed racing transmission with shift paddles that feeds the rear wheels.

Powertrain by A pair of electrics motors mounted on the two front wheels each contribute 75 kW (102 hp), or a total of 204HP, lifting the combined output to 767HP. The German maker notes that the extra power from the electric motors is available for around eight seconds when the system is fully charged.

In the 2011 Porsche 918 RSR, the two electric motors offer a torque vectoring function with variable torque distribution to the front axle. This additionally increases agility and improves steering response. Mounted upstream of the rear axle, the mid-engine is integrated with a racing transmission also based on the RS Spyder race car.
