Peugeot Supercars 908 V12 HDI


This supercar created by Peugeot uses 5.5 liter diesel V12 and turbochargers objective has more than 700hp. The selection of engine structural design has been based on a 100° twelve-cylinder V design, with a 5.5 litre cylinder power. It is the utmost cylinder capacity allowed by the regulations and was selected for its proficient operation at low speed. In the first instance, it also allows engine power to be imperfect yet also allows advance development.

Peugeot supercars has proclaimed its pronouncement to take up a new technological challenge: to win the Le Mans 24 Hours, one of the most prominent and most difficult motor races in the world, , with a vehicle powered by an HDi diesel engine, prepared with a diesel particulate filter system. With attracts more than 200.000 spectators every year, Peugeot will use this symbolic race as an opportunity to showcase their brand values: reliability, dynamic performance, style illustrated by the feline lines and, finally, innovation expressed, in the midst of other means, by the use of technology that is environmentally friendly.

The supercars Peugeot will be at Le Mans with a diesel engine because the PSA Peugeot Citroën group is now a world leader in diesel technology, which is a Common rail direct injection. In 2005, HDi technology can be found on more than 70% of vehicles sold by the brand in France and more than 60% in Europe. Peugeot established its commitment and strategic policy to lessen exhaust emissions in 2000, by fitting as standard equipment on the HDi engine in the 607 a diesel particulate filter system. And Peugeot renowned the production of the millionth vehicle fixed with a diesel particulate filter system in December 2005.

The HDi diesel particulate filter technology will be brought by the production car to the competition arena to show its qualities in tremendous conditions of endurance and performance while respecting the environment. On the one hand, the number of cylinders results from the desire to keep bore diameter extremely close to that of a production series engine. On the other hand, it could make best use of Peugeot’s diesel combustion knowledge to limit the stroke to a reasonable value. Well known for its good balance, the V12 architecture also diminishes vibration to a minimum.

Having the 100° V angle, of the V12 architecture, The Peugeot supercars allows the height of the centre of gravity to be lowered without moving the torsional inflexibility of the engine. Two diesel particulate filters are installed at the end of each of the exhaust systems. They will give a guaranteed control of exhaust emissions under all operating conditions through technology which has come directly from production cars. The numbers 1.195.520 and 1.195.521 which are the numeric production numbers of the filters in the overall production total of all filters since the introduction on to Peugeot vehicles were the two diesel particulate filters built-in to the engine being presented.

The supercar is expected to perform more than 515kW (700 bhp) of power and a torque output greater than 1.200 Nm. The level of supercars performance is without example in a diesel engine and is a direct result of Peugeot’s present level of knowledge in diesel technology, connected to the mechanical characteristics of the V12. One of Peugeot supercars Sport’s essential partners on this project is Bosch, who makes an active contribution to the specification of the fuel injection components and to the engine management system. Peugeot Sport was re-organized at the end of the 2005 World Rally Championship With the arrival of this new challenge. Under the supervision of technical manager Bruno Famin, Claude Guillois was named as manager of the engine department gratitude to his experience of race engines, supercharged engines and knowledge of production engine design. The department is based at Peugeot Sport’s Vélizy facility that comprises three engine test beds including one for simulation.
