The 320D is a great car, but it is amazing how much more grown up the F30 330D feels in comparison.
Weird how an engine can completely transform the feel of a car. 330D feels heavier and more planted (that's probably because it is heavier
), but has constant thrust all the way to red line, and never feels 'thrashed' like the 320D.
The 320D is quite eager and 'zingy' by comparison though, nice......and as you say, very rapid in the lower rev range.
