Here’s a slick new commercial from Audi featuring its R18 TDI racer. The R18 TDI has been created by Audi in an effort to add to its string of Le Mans 24 Hours victories, and is the first closed coupé design to be used by the Ingolstadt giants since 1999. Power comes from a 3.7L V6 TDI unit.http://www.youtube.com/watch?v=mPIENo6PCF4
