0-60mph is irrelevant in real world.
The F30 is only 0.3 seconds slower than the current 335i: a fine reason for BMW saying sayonara once and for all to a new 335i.
5-60mph is 7.1s for a 3400lbs N20 car and 5.5s for a 335i. Still a BIG difference. And the F10 335i will have probably 320HP and an engine note not to be ashamed of.
