2008 Peugeot 908 HY

(from Peugeot Press Release) THE PEUGEOT 908 HDi FAP HYBRID

Peugeot Sport presented a 908 HDi FAP equipped with a hybrid power plant at the final round of the 2008 Le Mans Series at Silverstone, this weekend.

Peugeot Sport profited from the final round of the 2008 Le Mans Series at Silverstone to unveil a 908 HDi FAP equipped with a hybrid power plant, featuring a kinetic energy recovery system. The 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. 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:
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

The 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. This energy reserve can be used for:
--Either 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)
