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.


The engine

The chosen engine architecture is a 100 degrees V12 with a capacity of 5.5 litres. This is the maximum capacity permitted by the regulations and was chosen due to its greater internal airflow at low engine speeds. It also gives potential future development opportunities to use different grade fuels.

The choice of a twelve 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 vibrations to a minimum.

The 100 degrees V angle, like the V12 architecture, makes it possible to lower the height of the 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.

The two exhaust systems are as short as possible. On each side a 6 into 1 exhaust manifold is connected to a Garrett turbocharger, then to a very compact diesel particulate filter before ending in a side exhaust pipe, located in front of the rear wheel.

The expected level of performance - a power of more than 515 kW (700 bhp) and a torque in excess of 1200 Nm, which is unprecedented for a diesel engine - is a direct results of Peugeot's diesel engine expertise, combined with the mechanical specification of the V12 engine.


Electronics

Peugeot 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.
