Peugeot 908 HDi FAP Hybrid
Peugeot Sport has unveiled the 908 HDi FAP Hybrid powered race car in the final round of the 2008 Le Mans Series at Silverstone over the weekend.
Sporting a new silver-grey livery, the Peugeot 908 HDi FAP Hybrid features a 60 kW gear-driven electric motor-generator in lieu of the conventional starter motor; 10 battery packs of 600 lithium-ion cells and an electronic power converter which controls the flow of energy between the batteries and the motor-generator.
The 908 HDi FAP’s “HY” technology also enables a proportion of the kinetic energy produced under braking to be either recovered or stored rather than dissipiated.
The 908HY can be powered in one of three exclusive ways: electric mode only (e.g. in the pit-lane), delivering extra power thanks to an additional boost of 60 kW (80 bhp) for approximately 20 seconds per lap, either automatically when re-accelerating or when the driver chooses to make use of it (‘push to pass’) or to reduce fuel consumption for the equivalent level of performance thanks to the mechanical energy recovered (between three and five per cent).
The system featured on this demonstrator comprises three key elements:
1) A 60 kW gear-driven electric motor-generator which takes the place of the conventional starter motor
2) 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)
3) 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
Michel Barge (Peugeot Sport, Director): “This hybrid 908 HDi FAP is in perfect keeping with the overall mission of our endurance racing programme which covers not only the challenge of competing, of course, but also the fact that as a car manufacturer we can use motor sport as a research and development tool for the Peugeot brand as a whole. 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.”
