Frank Biela and Marco Werner of Germany and Emanuele Pirro of Italy drove the Shell diesel-powered Audi No. 1 car to victory, proving that last years diesel win for Audi was not a one off. The R10 TDI has an all-aluminium, 5.5-litre, twelve-cylinder bi-turbo TDI engine producing over 650 bhp!
As the TDI technology filters down to the road cars I will be trading up to a road going Audi R10 next year… well maybe not.

Proves green motoring isn’t just about Toyota hybrids, either.
