What's the difference in performance and mpg?

Also how is it different, engine design, software, turbo etc?

[F31-340i]

I went from an 184ps E46 330d to a 231ps E91 330d.

I went to a dealer to get a 320d - and test drove that first - I was very impressed at how the E91 320d felt as quick (if not quite as refined) as my old 330d.

I then tried a E91 330d and was very impressed at how much extra poke it had over the old 330d.

I'd say mpg is slightly better for given performance, but as its a quicker car I find I give it more beans, more often, than the old one so hard to compare and I end doing about the same. On a longer run, cruising at 80, the E91 is better - 43-45mpg easily achiveable.

In short, going from a E46 to a E91 330d was in my opinion a massive leap in performance and everything else.

Is there a 200bhp 3.0d as I've driven a 330cd auto

IIRC the 2004 onwards e46 330cd had 204ps (200bhp) compared to the earlier models 184bhp....

What made the difference, new engine block, map etc?

New block I think, as there is a slight capacity difference....
the 184 was 2926cc, the 204 was 2993cc

How about the 204 compared to the pre lci e90

E90 330d got an all new Aluminium Block engine with a variable geometry turbo.....
