Well this morning I commuted a nice 287 miles average speed 66mph and amazingly average mpg was .... 54.6mpg
Car 231bhp 330d auto with climate on all the time.
How some people can only get low to mid 40's from 2ltr tdi's really is beyond me. Probably something wrong with the cars or driving style hasn't adapted to get the most out of the tdi.
For me the learning is leave cruise control on whole journey.

That's after being superchipped as well. The skins of rice puddings are still not quaking through the land though
Max I have seen is 81+ over 28 miles.

I think you're forgetting that motorway work is often when a car is at it's most efficent hence why extra urban is always the highest quoted offical MPG figure.
This is especially true if you are able to leave the CC on the for the whole journey which implies you were able to stick to a nice steady speed which also helps a lot. I had a fabia diesel which used to do 45-50mpg on the motorway, even at a steady 90 leptons.
Drive your BM across London or even round the M25 on a friday afternoon and i bet you'll be back in the 40-50mpg range.

compare that figure to what you'd get out of a 320 ed (I think its ~80mpg extra urban). people get 45mpg by driving in stop/start traffic, or at higher speeds on the motorway
the 3 series is also quite a bit smaller than a lot of 2 litre cars. A mondeo for example has good room for 5, and a large boot, whereas a 3 series (especially the coupe) is compromised in the back and in the boot - the passenger\luggage dimensions are probably much closer to a focus, if not smaller

Speed (I guess drag) really comes into it on the motorway though, I noticed with mine if I eased off 15mph from my normal ideal speed I saw around 10-15 extra mpg
Absolutely. The power needed increases (at motorway speeds reasonably accurately) with the cube of the speed. So if you want to do 85mph rather than 70, you'll need 1.8 times the power.McSam said:

Id estimate c50miles of that trip was non M way but clearly still good average speed.
The other thing is music wasnt on too loud (too early really for that) engine I didnt notice it at all / couldnt hear it only the tyre noise. You'd only know it was a diesel by looking at the rpm counter and also the mpg guage.
Glad too I have the auto - twisted ankle last night - would have been 500+ gear changes possibly double that instead effortless changes.

I have seen 60mpg for a 40 mile trip from my Passat 1.9tdi 130, this was grannying it beyond belief with the aircon off etc.
I can easily see 50mpg most of the time if I am careful and do 65 - 70 on the motorway.
Even driving enthusiastically you will see 44mpg on a run.
Ive yet to have my car below 34mpg over a tank & I drive it properly else Id have got a 316d. I dont sit in London traffic but my commute is 28mph ave speed.... that averages 40-42mpg.I can easily see 50mpg most of the time if I am careful and do 65 - 70 on the motorway.
