Using simple knowledge, I introduce your new North American engines:
A5 -slightly higher tuned 2.0t
S5 - slightly higher tuned 3.0t
RS5 - most likely a twin turbo version of 3.0.
Audi will want to save on R&D costs so A5 and S5 will carry on with the engines. Unfortunately, this will mean that the B9 platform will again not be able to fit the 4.0 v8. Only option for the RS5 will be something similar to the new M4; a very high tunned 6 cylinder forced induction engine. Discuss.
