I've got a 740il and if I cruise along at 70 on a clear motorway I can get 32mpg.
I would have thought the 540i could easily match and if not beat this.

Doh.

If you wish to disagree with the BMW official numbers, then that
is entirely your choice.


I did some further sums on the official numbers. The combined
figure is usually half the urban figure and half the extra-urban.

Widening it out to 1/3 u + 2/3 e-u gives 27 mpg
and 2/3 u and 1/3 e-u gives 21 mpg.

I would have thought that most drivers, in general use,
would get between 21 and 27 mpg, unless their driving is
seriously skewed towards either town driving or motorway
driving.

I am just going on what the OBC tells me. 32mpg is average or a motorway run ast 70mph.

Thats a before & after dyno I'd like to see.

Most of the remappers quote 10% max on NA cars.

I think actually the correct answer is 'no'
