2012 Porsche 918 RSR Concept

2012 Porsche 918 RSR Concept - Porsche unveiled the 918 RSR at the Detroit Auto Show today, a 767 horsepower hybrid race car. Porsche's concept hybrid gets an extra boost from braking, which triggers the motors to act as generators when the front wheels brake.

With the Porsche 918 RSR, the manufacturer of sporty premium vehicles is presenting a high-end synthesis of 2010's successful hybrid concepts. The two-seater mid-engine coupé 918 RSR clearly reveals what happens when the technology fitted in the 911 GT3 R hybrid and the design of the 918 Spyder are transferred to a modern, innovative super sports car.
