The Peugeot 908 HDi FAP is a sports prototype racing car built by French automobile manufacturer Peugeot to compete in the Le Mans 24-hour endurance race, beginning in 2007 and which the company eventually won in 2009. It first competed against the Audi R10 TDI, becoming the second diesel engined sports car from a major manufacturer. This was Peugeot Sport's first Le Mans effort since the end of the Peugeot 905 project in 1993. It won 19 from the 28 races in which it raced between 2007 and 2010.The body is a carbon fibre monocoque instead of a conventional open structure. This configuration offers better rigidity and lower weight. Front and rear suspension are linked, steering is electrically powered, and the magnesium wheels are by BBS. The car measures is 4.65 meters long and and weighs 925 kg or 2,039 pounds.
The Peugeot 908 is powered by a 5.5 L (340 cu in) HDi diesel engine, the maximum size allowed by Le Mans Prototype rules. Its configuration is a 100° V12, the angle having been chosen to lower the center of gravity. Its output is over 730 horsepower and torque rating is 890 ft-lb. Oil systems are developed by technical partner Total. The electro-pneumatic controlled gearbox, designed and built by Ricardo, is longitudinal with 6 gear ratios, and the differential is self-locking.

It’s very interesting to see the impact of alternative fuels and technologies in the sport of motor racing. History has shown that these technologies eventually make it to everyday cars, where it benefits the average joe.
