The possible existence of an R8 supercar has outrightly been denied by an anonymous Audi source so keep on dreaming. But instead of doing that why not feast your eyes and ears on the Audi R8 V12 TDI concept which was shown by Audi during the 2008 Detroit Auto Show. This is the first 6.0-Liter V12 diesel engine found in a sports car producing 500 horsepower and so it is expected to make something of a legend out of Audi well at least in diesel technology.
The Audi R8 V12 TDI concept has a bland color of matt Grace Silver but it has a fascinating design and superb road handling capabilities. Its engine is closely related to the two-time Le Mans winner Audi R10 making the Audi R8 V12 TDI concept a supercar that sprints from zero to 100 km/hr in a matter of 4. 2 seconds.
The V12 TDI has a subtle design but hear the car roar and you will be instantly thrilled. Years of experience were relied upon by Audi engineers in making the Audi R8 V12 TDI concept.
