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. How did the four-ringed automaker fare? According to the commercial posted after the jump, the engineering team did a pretty good job.
