Suspension, steering, brakes:

Given 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.

Gearbox:

The gearbox is located longitudinally and the assembly can accommodate up to six gear ratios, the limit laid down by the regulations. It has been designed to withstand the enormous torque of the engine, while ensuring it is as lightweight and compact as possible. The gearbox is controlled electro-pneumatically.

Engine:

The Peugeot 908 will be powered by a 100° V12 HDi diesel engine with a capacity of 5.5 litres. This is the maximum capacity permitted by the regulations and was chosen due to its efficient operation at low engine speeds. It also gives potential future development opportunities to use different grade fuels.

The choice of a 12 cylinder engine helps keep the cylinder bore diameter very close to that of a production series engine. In doing so, Peugeot can call on its extensive knowledge of diesel combustion and also ensure the engine has a reasonable piston stroke. The V12 architecture, well known for its good balance, also reduces engine vibrations to a minimum. The 100° V angle, like the V12 architecture, makes it possible to lower the height of the engine’s centre of gravity without affecting the engine’s torsional rigidity.

Two diesel particulate filters are located at the end of each exhaust system and guarantee “smoke-free” operation of the engine under all conditions.
