After years of dominating Le Mans with the R8 (the racing prototype, not the street-legal supercar), Audi took on a new challenge with the diesel-powered R10 TDI. Peugeot joined the race both literally and figuratively with the 908 HDi FAP, so Audi fired back with the R15 TDI. This season, Audi is upping its game yet again with the R15 TDI Plus, but while the 908 soldiers on, don't think for one minute that the French team doesn't have a trick up its sleeve.
That trick comes in the form of the 90X, the next-generation Le Mans Prototype from Peugeot Sport. Designed to meet the 2011 regulations being set out by race organizers ACO, the 90X has been undergoing testing at undisclosed tracks in Europe. Peugeot's only released limited information on the car's development, saying little more than that it incorporates a new "shark fin" over the engine cover designed to keep it on the ground in case of a crash.
