0-250kmh for the 335i is in about 35 seconds. My N54 did that in 32/33 seconds as I recall.
There is some flat road(highway) around here where we can do that stuff (more than)sometimes.
My ex E90 M3 did that in >25/26 seconds or so, don't remember.
The N20 needs 17 seconds more than the N55 to do that, looking at that video.
