Peugeot unveil 908 HDi FAP Hybrid  
Peugeot Sport waited for the final round of the 2008 Le Mans Series at Silverstone to unveil a car equipped with a hybrid power plant, featuring a kinetic energy recovery system. The Peugeot 908HY was presented in a new, specific silver-grey livery and will provide a foretaste of what Peugeot's next endurance racing challenger could resemble, although its use will depend on the regulations that will govern LMP 1 cars from 2009.

The Peugeot 908HY's technology enables a proportion of the kinetic energy produced under braking to be either recovered or stored. In the case of a non-hybrid car, this energy is lost and simply dissipated in the form of heat via the brakes. However, when harnessed, it enables the vehicle's efficiency to be improved in one of two ways:

  • Enhanced performance with no increase in the amount of energy consumed, thanks to the combination of the stored mechanical energy and the energy produced by the internal combustion engine
  • Reduced fuel consumption for the same level of performance, thanks to the availability of stored mechanical energy

The system featured on this demonstrator comprises three key elements:

  • A 60 kW gear-driven electric motor-generator which takes the place of the conventional starter motor
  • Batteries which permit recovered energy to be stored in 600 lithium-ion cells divided into 10 battery packs (six in the cockpit instead of the conventional battery and four on the left-hand side of the floor pan)
  • An electronic power converter (located in the rear part of the front left wing) 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 (e.g. in the pit-lane)
Internal combustion engine only
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.

Michel Barge (Peugeot Sport, Director): 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."
