Porsche 918 RSR Coupe combines forms submitted last year and 918 Spyder technology supersportista 911 GT3 R Hybrid.

Presented a few hours before the Detroit car is part of the "Porsche Intelligent Performance" (Intelligent efficiency) and uses a hybrid system of F1 cars of Williams, combining a powerful petrol engine and two electric motors.

These engines assist in positioning the rear gasoline engine with 563 hp power at 10 300 rpm, which drives the rear wheels. By Porsche has not yet reported details on this engine, but we can be almost sure that it is a V8 engine with 3.4 liters volume, known from the 918 Spyder.
