The Audi R10 TDI is dead. Long live the R15. That's the moniker given to the next-generation Le Mans prototype set to wear the interlocking rings. The car will make its race debut in March at the 12 Hours of Sebring, and by the time the 24 Hours of Le Mans rolls around in June, Audi will have three of the cars ready to defend the trophy won by the R10 earlier this year. Details on the new car are very limited at the moment. All that's known is that it'll have a smaller, lighter, more efficient TDI motor, will once again be a roadster, and is a more significant change than Audi undertook when it went from the R8 to the R10.

The car will be publicly revealed closer to the Sebring race. According to the ALMS website, Audi Motorsport honcho Wolfgang Ullrich was quoted as saying, "It was clear to us that we must develop a new car if we wanted to continue to be successful in Le Mans." We read that as code for, "Those Peugeots were f**king fast this year. Here's our answer." By the time the cars hit the grid at Circuit de la Sarthe, the hype's going to be at a fever pitch. Bring it. Thanks to Ashutosh for the tip!
