It was said before that Audi would produce a diesel version of it’s flagship, the R8. Thanks to the phantastic race technology they use on circuit, it would not be hard for the Audi guys to fix it into the R8. Rumours say it’s planned for 2009, but according to the Germancarblog the first new version of the R8, will be a Targa! So the diesel will probably stay out a little bit longer.
