German Autobahn and Diesel = im impressed !
Discussion
Coming from a Subaru Impreza WRX i just added a 330d to my fleet.
However the point that makes the big difference is the MPG:
If i accelerated my WRX to 140mph+ the engine was starting to get 11-12 MPG.
However in the diesel i still get 29 mpg at those speeds !
Im very impressed so far. I think no Prius could match my MPG at 140 mph.

)I drive a 2 year old 335d coupe, have to say it's the perfect 'everything car', resonably quick, gets 38mpg on the average motorway journey and if you keep off the big turbo you'll easily get 42-45 on a nice gentle run. Quick enough and handles well enough to have a enjoyable cross country drive.
I do miss the revs of a nice petrol engine though.....

I'm pretty sure that a 330d isn't doing 29mpg at a steady 140mph on a flat road (well, mine certainly doesnt get anywhere near that number at those sorts of speeds.....)However the point that makes the big difference is the MPG:

You don't get 29 mpg at 140mph in a BMW 330d. (Max Torque +1) However in the diesel i still get 29 mpg at those speeds !
Auto Bild tested the fuel consumption of 16 cars at speeds up to the maximum each vehicle was capable of and a selection of the results are plotted here
One of the most startling things that Auto Bild noticed was how inaccurate the consumption figures quoted by the on-board computers were. At maximum speed the Porsche Cayenne Turbo was indicating that it was using a modest 29.9 litres /100km (9.55mpg), where as the actual consumption was 67 litres /100km (4.21 mpg).
The AB article also plotted consumption in a Prius vs a couple of Beemers - very interesting to see that at speeds of above about 90mph the 535d Touring was more economical than the Toyota! Here
The Auto Bild test was done ages ago (2006) - but if anyone has some more accurate figures (NOT video of your on-board computer!) of 100mph plus economy figures it would be interesting to see them.

Fuel economy at 0.8-1.0 leptons is very important to me...

At an indicated 80mph on the flat, my 330cd sits at 50mpg. It does much the same at 90mph. At 130mph it sits at 30mpg. All these figures done on cruise control and using normal Shell diesel. Its a manual, so slightly more economical than the auto. Never fail to get less than 500 miles from the tank and it's usually somewhere between 550 and 600 from 60litres as I spend most of my time on the motorway.

Sure, using the mpg needle. At an indicated 70 on the flat my 530i often sits at between 45 and 50mpg but of course it never averages anything like this - because no trip ever involves just 'the flat' and no external influences.Edit: I must say though just checked your profile and what an absolutely epic car history you have!

One thing I've certainly noticed with BMW's (and other german cars) is that they appear to work well at high speed. Many cars seem to not perform well at 'extended' speeds, but BMW's tend to have a natural gait at 90+ and real composure at those speeds. It's obvious that they're tested and tweeked to be a sound companion on the autobahn, not UK motoways.
It's interesting to read 'The Driver' By the guy who runs the Team Politzei M5 in the Gumball. He takes his high speed driving pretty seriously, having crossed the US in 32 hours and 7 minutes, an average speed of over 90Mph. He calculates the trade offf between running at higher speeds Vs. Having to make more fuel stops, and with that 4.4 V8 the economy falls off a cliff as soon as you push past 100Mph and run at higher revs. I've no doubt he'd have been better off in a 330d - smaller, less frontal area, lighter, and far more economical, whilst still capable of all day cruising at the cusp of the tonne.

In a recent trip through France in my f10 520d I experimented with mpg at different speeds, putting the cruise on and calculating average over 20 min. I got:
65mph : 60mpg
70mph : 55mpg
80mph : 50mpg
90mph : 45mpg
100mph : 38mpg
Speeds over 100 and mpg started to fall off a cliff. So 30mpg at 130mph is well impressive.
Those speeds are all indicated, so slower than gps verified.

70mph : 55mpg

As aerodynamic drag increases with the square of velocity, and fuel consumption is broadly equivalent to power output, it's not suprising that fuel economy increases non linearily with speed. That is also why pretty low powered cars can still go say 120mph, but you need something relatively pokey to get to a genuine 150mph.
