Ok, I gotta chime in here. I have owned a 2009 335i X-Drive and recently traded that for a 2011 335is. The 335is is quite a bit more responsive than the 335i. If the F30 is based on the N55 engine (I'm unsure of this), there is no way it would be "faster" than a N54 with overboost. Just not possible. My 335is still surprises me at times when accelerating. Can anyone say for sure if the F30 335i will be using the N55 engine?
