Aha, so it seems the info I was told today has some truth in it: 5-door = Sportback
In a way, a Sportback RS3 is like a smaller Avant RS4 or RS6.
I think we all have some idea about what the front of a RS3 will look like (slightly TT-RS) but hopefully Audi will make the rear more stylishly individual than they have with their other 3-series. We'll see.
Also, will the RS3 have the Sports Differential which the current S4 quattro has an option for? It's a feature which makes it more fun to drive.
