Chassis

The body

The monocoque body is made of carbon and presents a truly closed structure, contrary to the 905, which was a "racing car" with a detachable tubular rollover bar.
This type of structure offers strong natural rigidity (the “eggshell” effect) and allows the weight of the monocoque body to be optimised.

Body and aerodynamics

Created from scratch at the beginning of 2006, Peugeot Sport’s aerodynamics department had the difficult task of designing in just a few weeks an exterior body that was both original and aerodynamically efficient.Three months after the appointment of the aerodynamics project team leader,
a model of the car was undergoing the first tests in the wind tunnel!The car's profile results not only from the necessary compromise between
aerodynamic efficiency and drag, but also the need to provide optimum airflow to the different radiators and intercoolers located within the generously dimensioned bodywork.

Suspension, steering, brakesGiven the challenge of designing a complete car in record time and the particular constraints of the HDi DPFS engine, the Peugeot Sport team relied on proven solutions for the front and rear suspension design, the electric power steering and the brakes.

The gearbox This is positioned longitudinally and will allow the fitment of up to 6 gear ratios, the limit laid down by the regulations. It has been designed to withstand the enormous torque of the engine, while ensuring optimum weight and size characteristics. The gearbox is controlled electro-pneumatically.

Electronics

The 908 will benefit fully from Peugeot Sport’s considerable expertise and knowledge in electronics, acquired as a result of its extensive experience with WRC cars – which are generously equipped with electronic systems – and in particular with respect to their experience of electronically controlled differentials.Peugeot Sport will also benefit from the experience of the main supplier Bosch, who will be supplying and developing the “car system” on the basis of specifications provided by Peugeot Sport.

A high level of performance is therefore expected in terms of “traction control”,
a key function for controlling engine torque in a race track environment, whilst also ensuring optimum performance of the Michelin tyres.
