Difference between xxx35d and xxx40d?
Discussion
From BMW's site today:
X5 30d = 245bhp
X5 40d = 306bhp
530d = 245bhp
535d = 299bhp
330d = 245bhp
335d = 286bhp
The 30d all seem to be the same output, so I guess they're identical engines. However the next diesel up is a different output on each model. And on the X5 it's called a 40d instead of 35d, but only a marginal increase in power on the 535d.
Does anyone know the differences?

As far as I know the 40d engine is a 3.0 Single Turbo unit while the 35d engine is the more familiar 3.0 twin turbo unit.
Interesting... so the 40d is the 30d with a remap?Dave

Just checked the BMW site, and it states: "Twin turbochargers with variable turbine geometry"
So the 40d is a twin tubby unit.
I did think it was a twin turbo to start with but he told me otherwise - apologies OP
EDIT: I'll go and tell him what a st mechanic he is

The 4.0D is a twin turbo with variable geometry turbos and is 3.0 litre capacity. Badged as a 4.0 as a marketing ploy against Audi and Mercedes with their big capacity diesels but with lower emissions and better fuel economy.
Power differences between models is almost certainly down to management programming to give driving characteristics appropriate for the application.
