Audi has released a great commercial for the Audi R18 TDI quattro, focussing on the Ultra lightweight construction of it. A must see!
Audi loves talking about the lightweight technology used to build its mighty turbodiesel LMP racers. While the last-generation R15 utilized a 590-horsepower twin-turbo 10-cylinder diesel engine, revisions to the rulebook forced Audi to alter the oil-chugging powertrain. The newer R18 TDI is powered by 3.7-liter V6 turbodiesel that pumps out around 575 horsepower, yet weighs 25-percent less than the previous mill and drinks fuel at a slower rate.
Besides the engine, Audi has employed aluminum and carbon fiber in an effort to keep the weight of the R18 TDI as low as possible.
