At last weekend’s Le Mans Series race meeting at Silverstone Peugeot Sport unveiled a version of its 908 LMP1 car equipped with a hybrid power train, featuring a diesel engine and a kinetic energy recovery system.

The Peugeot 908HY’s hybrid technology enables a proportion of the kinetic energy generated by braking to be either recovered or stored. The system comprises a 60 kW gear-driven electric motor-generator, which takes the

place of the conventional starter motor, batteries which permit the recovered energy to be stored in 600 lithium-ion cells divided into 10 battery packs and an electronic power converter which controls the flow of energy between the batteries and the motor-generator.

The Peugeot 908HY can be powered in one of three ways: electric mode only, internal combustion engine only or a combination of the two. In the course of a lap of Le Mans, for example, the system will recuperate energy for between 20 and 30 seconds.

Peugeot Sport director Michel Barge said, “After innovating through the use of our HDi FAP technology in competition, running a hybrid car in endurance racing would give Peugeot a chance to gain extremely valuable experience that would benefit the development of production cars. Whether we use this technology or not in 2009 will obviously depend on the details of the new regulations published by the Automobile Club de l'Ouest."
