What's the differences currently between the 3.0 ltr diesel engines BMW have to offer.
The x40d the X35d and the X30d.

The 35d and the 40d is the same engine with twin turbos, 313hp, and used in the 335d, 535d, 640d, 740d, X5 40d.....

The 30d is a single turbo 258hp engine and used in the 330d, 530d, 730d, X5 30d....

Nice 1, didn't realise the 40d and the 35d were the same engine, thanks.

I test drove an X5 30D and then a 40D immediately after.

I couldn't tell the difference.

40d has much more low down torque and a more linear power deliver.

Key thing is 60+bhp more.

Indeed. However, the difference when actually driving the cars was barely discernible.

335d is the same as the 330d in this respect - 2000rpm at 90mph.

I haven't tried an X5 40d, but have tried 335d/330d and 535d/530d. The 30d is still a very good engine, but the performance is quite different to the 35d in my experience.

The X5 and 7 series lend themselves to a more relaxed driving style (although I haven't tried the current model X5), and become rather ungainly when pushed through corners. So perhaps if I was looking at one of those, I may consider the 30d engine. In a smaller car which handles pretty well (I have AC Schnitzer springs) the 35d engine is impressive.
