Yesterday at the 2011 NAIAS Detroit Auto Show, Porsche took the covers off their latest concept car, the 918 RSR Racing Lab. It looks magnificent but it’s really what makes it move and punch it’s packing that’s got our attention. The supercar is built on a stiff carbon fiber plastic monocoque and is gets power from a direct-injected V8 that dishes out 563-hp, the same found in the RS Spyder. There are actually two electric motors on the front wheels which contribute a burst of 150 kW bringing overall output to peak drive power of 767-hp. This additional spark is generated during braking and is stored in an optimized flywheel accumulator and is available for roughly 8 seconds when the system is fully charged.
