Is Audi making the model TT in 2007?

Yes they are and they have already the 2008 TT in 4 versions. The 2.0 coupe and roadster as well as the 3.2 coupe and roadster.
I had the rare opportunity to drive the pre released 3.2 Quattro coupe in Germany this year. 245km/h was what I reached on the Autobahn between Ingolstadt and Stuttgart. It was solid. The ultimate fun came in Boxberg with the R8...WOW!!!
