Just to round off the discussion about Georg Kacher, new model specifications are not set in stone before production is signed-off. They can change often and even change back again! Indeed, the RS3 has been an 'off and on' project. According to the Dutch version of German magazine, Auto Motor und Sport, (Erik) the car was cancelled until someone came up with idea of narrower rear wheels.
As far as other models are concerned. When I met Michael Renz (Audi, Leiter Marketing) at Geneva in 2005, he said that the RS4 model that would follow the B7 would have a twin-turbo V8. Audi believed that TT was the way to go to provide ample power and reasonable economy in a flexible package. In fact, there was a plan to put the new 4.0 litre V8 TSFI in both RS5 and RS4. Clearly, this changed when the world economy went to hell in a hand basket. It was also planned to put the V10 in the S7. That changed to. It would be fascinating to be a fly on the wall at product planning meetings in Ingolstadt.
Besides all that, half the fun of these forums is to figure out what is coming and when. I wonder to what extent if any we inspire marketing departments to make certain products? Given that Qisha recently asked us what we wanted in future RS products and the superb feedback that came from the thread, maybe our collective thoughts do create value.
I eagerly await the RS3. I also eagerly await the Quattro concept. Audi is still making fantastic cars.
