Peugeot decided to reveal a new model that will take up a new technological challenge. It plans to win one of the most demanding motor racers in the world, the Le Mans 24 Hours. The carmaker relies on the fact that the 908 V12 HDI model showcases their brand values like reliability, dynamic performance, style illustrated by the feline lines and environmentally friendly technologies used. The choice of engine architecture has been based on a 100 12-cylinder V design with a 5.5-liter cylinder capacity. This is the maximum cylinder capacity that regulations allow and was chosen for it efficient operations at low speed. The level of performance expected more than 700 BHP of power and a torque output greater than 1.200 Nm. On September 28th 2006 the model will have the presentation of the scale at the Paris Motor show and at the beginning of December will take place the first drive of the car by test driver Eric Hilary.
On 14 June 2005, Peugeot announced its decision to take up a new technological challenge: to win one of the most prestigious and most demanding motor races in the world, the Le Mans 24 Hours, with a car powered by an HDi diesel engine, equipped with a diesel particulate filter system.
This symbolic race, with attracts more than 200.000 spectators every year, will be used by Peugeot as an opportunity to showcase their brand values: reliability, dynamic performance, style illustrated by the feline lines and, finally, innovation expressed, amongst other means, by the use of environmentally
Why will Peugeot be at Le Mans with a diesel engine
The PSA Peugeot Citroen group is today a world leader in diesel technology. Common rail direct injection HDi technology can be found on more than 60% of vehicles sold by the brand in Europe in 2005 and more than 70% in France. In 2000, Peugeot confirmed its commitment and strategic policy to reduce exhaust emissions, by fitting as standard equipment on the HDi engine in the 607 a diesel particulate filter system. In December 2005, Peugeot celebrated the production of the millionth
vehicle fitted with a diesel particulate filter system.
Today, it is the production car which brings its HDi diesel particulate filter technology to the competition arena, in order to show its qualities in extreme conditions of endurance and performance, all the while respecting the environment.
The Peugeot HDi diesel DPFS:
The choice of engine architecture has been based on a 100 twelve-cylinder V design, with a 5.5 litre cylinder capacity.
This is the maximum cylinder capacity that regulations allow and was chosen for it efficient operation at low speed. It also enables engine power to be limited in the first instance, but also enables further development.
The number of cylinders results, on the one hand, from the wish to keep bore diameter very close to that of a production series engine, in order to make best use of Peugeots diesel combustion knowledge and, on the other hand, to limit the stroke to a reasonable value. The V12 architecture, well known for its good balance, also reduces vibration to a minimum.
The 100 V angle, of the V12 architecture, allows the height of the centre of gravity to be lowered without affecting the torsional rigidity of the engine.
Two diesel particulate filters are mounted at the end of each of the exhaust systems. Through technology which has come directly from production cars, they will provide a guaranteed control of exhaust emissions under all operating conditions.
The two diesel particulate filters fitted to the engine being presented, carry 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.
The level of performance expected more than 515kW (700 bhp) of power and a torque output greater than 1.200 Nm is without precedent in a diesel engine and is a direct result of Peugeots current level of know-how in diesel technology, linked to the mechanical characteristics of the V12.
Bosch is one of Peugeot Sports essential partners on this project, making an active contribution to the specification of the fuel injection components and to the engine management system.
Peugeot Sports engine department:
With the arrival of this new challenge, Peugeot Sport was re-organised at the end of the 2005 World Rally Championship.
Claude Guillois, under the supervision of technical manager Bruno Famin, was named as manager of the engine department thanks to his experience of race engines, supercharged engines and knowledge of production engine design. The department is based at Peugeot Sports Vulizy facility, which includes three engine test beds, including one for simulation.
The next important dates:
* 28 September 2006: presentation of the scale model at the Paris Motor
* 30 September 2006: Peugeot V12 HDi DPFS engine to be run on engine
* Beginning December 2006: first drive of the car by test driver Eric Hilary.
In addition to Peugeots three main technical partners, Total, Michelin and Bosch,
Eurodatacar will be working with them on the Le Mans Series programme.
