Porsche 918 RSR Concept 2011
Porsche 918 RSR Concept made the world premiere at the Detroit Auto Show 2010 earlier this month. The 918 RSR concept is a high-end synthesis of Porsche’s 2010 successful hybrid concepts – the 911 GT3 R Hybrid and the 918 Spyder. It is a true ‘racing laboratory’ featuring an updated V8 engine from the successful RS Spyder race car with an output of 563 hp at 10,300 rpm. In addition, it features electric motors on the two front wheels that each contribute 75 kW, i.e. a total of 150 kW, to provide peak drive power of exactly 767 hp. This additional power, which is generated during braking, is stored in an optimized flywheel accumulator. Find more details on the way flywheel accumulator functions in the official press release after the jump.
