Autocar are now stating that the R8 will be the first Audi ever to break tradition with the 155mph restriction but also break the 200mph barrier with a claimed top speed of 205mph. It's not sure if they are talking about the 4.2L v8 or the v10 but as that is no release date for the v10 would lead me to believe that it is the v8 they are talking about.

This would put it not only ahead of the Gallardo, F430, 997Turbo and Z06 but miles ahead of the M5 and M6 as well as in touching distance of the 599 and Murcielago.
