The aim is no longer to obtain give our researchers a great test bed, the maximum amount of power from the which, in the very short term will benefit engines, but to extract the maximum mobility for all. performance from a fixed amount of fuel. This energetic efficiency challenge is relevant to the preoccupations of the car Thierry de Feydeau industry and the everyday motorists.
