Lots of rumour with the B9 chassis, and what powerplant it'll have, if there is one at all.
Don't believe they'll leave the run at just RS5 though. What comes after the RS5?
Wont be the 6, won't ever be a 3 or an 8... The R8/R10 wont affect the RS models either.
There is a market for 4-door RS models, so got to be an RS4 surely?
