E36 in Europe = 280 something and 321bhp compared to 250bhp S4
E46 in Europe = 343bhp compared to 344bhp S4
E92 in Europe = 420bhp compared to 414bhp RS4?
Seems likely us Europeans will get a higher output than the RS4, because M don't want to have lost that battle with this generation and at some point during its lifespan, the next RS4 with 450bhp+...
And that's the crux, this M3 has to compete with the next RS4 as well and unless they bring out an EVO model, going for less than the current RS4 would leave them with a massive marketing disadvantage and that doesn't sell cars to the non-hardcore drivers set.
