Audi R8 V12 TDI concept (2008)
Launched at the 2008 North American International Auto Show in Detroit, the R8 V12 TDI Le Mans paired Audi's 6.0-liter V12 TDI of the European market Q7 with the sportscar chassis of the R8 Mk1 as a measure to show a road car that could authentically pay tribute to Audi's Le Mans dominant R10 TDI with its own V12.
