The star of the 30-second TV commercial for Audi ultra lightweight technology is a masterful victor of the 24 Hours of Le Mans: the Audi R18 TDI. This lightning-fast vehicle travels elegantly along the track and concludes the race in the pit lane. Here, a mechanic ensures that the vehicle is spruced up. He ends up discovering a bit of fluff on the spoiler of the powerhouse and blows it off. The Audi is so light that it gently rolls forwards.
