Peugeot wants to be environmentally-conscious automaker not only on the roadways, but also on the track. After the launch of the 908 last month, the French automaker has now unveiled a diesel-hybrid version at the 2011 Geneva Motor Show. The Peugeot 908 Hybrid4 takes advantage of the latest in diesel-hybrid technology that not only allows it to burn oil in a cleaner way, but more importantly, enables it to remain on the track for an even longer period of time.

Like many other hybrid racers, the car's electric motor uses regenerative braking technology, that essentially stores kinetic energy generated while braking. In turn, it feeds it back into the driveline during acceleration. In fact, the system provides a short few second power boost when activated. The recovered energy is stored in lithium-ion batteries before it's automatically released to power the rear wheels. The 3.7-liter diesel V8 has a total power output of 550 hp and the hybrid system produces an additional 80 hp.

Peugeot states the objective for the new car is to run it at the official pre-Le Mans 24 Hours test day at the French circuit this April. An official 24 Hours of Le Mans entry may not be too far off.
