Detroit 2011 Auto Show
Porsche 918 RSR
Seth FletcherThe most extreme performance car on the showroom floor was undoubtedly the Porsche 918 RSR, a mid-engine hybrid supercar with two electric motors in front and a flywheel accumulator, which stores energy during braking and then releases it on demand. It’s an exotic sibling of the already astounding 918 Spyder hybrid concept. Altogether, the V8 racing engine (which produces 563 hp at 10,300 rpm) and the two 75 kW electric motors generate a peak 767 hp. Jalopnik has a good explainer on the flywheel technology.
