Gumpert is entering a hybrid version of its supercar, the Apollo, in the Nurburgring 24-Hour race. Instead of the normal car's Audi 4.2-liter twin-turbo with 650 HP, the racer gets a 3.3-liter V8 with something like 630-HP, in addition to a 100kW electric motor powered by a lithium-ion battery pack. The 190 kilos of batteries will be recharged by application of the brakes, but it isn't clear exactly how the electric motor will be applied -- slow speed (aka pit lane) use only, or to provide an extra boost during the race.

The car will be driven by Heinz-Harald Frentzen and Dirk Muller. The hybrid Apollo will test its fortunes against the Audi R8 and Lexus LF-A, both of which are in the same class. If the car does well, it could mean good things for the introduction of hybrid technologies into other race series like Formula 1.
