Peugeot 908 HYbrid4

From Peugeot press: The new 908 was designed to comply with endurance racing's latest regulations and will play a part in the 2011 offensive of the Brand whose commitment in favour of the environment represents a major part of its activity. Indeed, the combination of driving excitement with environmentally- respectful performance at the very highest level is dialled into Peugeot's brand identity. This commitment will now also be championed by its Hybrid4 technology which combines diesel and electric power, two fields in which the Brand has forged a solid reputation for excellence.

Since the unveiling of the team's demonstration hybrid car at Silverstone, in 2008, Peugeot Sport has continued to work on this technology in extremely close collaboration with the Group's engineers.

The system employed by the 908 HYbrid4 recovers and stores the kinetic energy generated under braking before feeding it back into the driveline during acceleration. Using this recovered energy in this way significantly improves the efficiency of the powertrain.

The system provides a power boost of 60kW (80hp) during the seconds that follow its redelivery. Recovered energy (500kJ between two braking phases) is stored in lithium-ion batteries before being automatically fed to the rear wheels under acceleration (no "push to pass" function). It will be possible to run in electric mode only along the pit-lane, and it is this mode that will be used for the car's homologation.
