The faster you go the more energy you'll need.
So I have been driving to barabra a couple times a week and did a little test on the MPG
Couple things I noticed...now let me remind you that the times of the drive and the weather conditions were pretty much the same for all trials...there were no stops or presses on the breaks and the MPG averages were started once the car was on the freeway and on cruise control till the off ramp at my destination
I noticed that @ 65MPH I got 31.1 MPG but interesting enough at 75MPH I got only 26.3MPG
now this might be no biggie but I found it rather interesting how only an increase 10MPH can decrease fuel consumption by some much
The faster you go the more energy you'll need.
Its a BMW who cares about fuel consumption . I drive my Honda if I want to get there cheap. I drive my Bimmer for image........
our cars are about as aerodynamic as a brick.
All cars runs optimally at certain speed have you tried to see what your fuel mileage is at 55MPH? I am wondering if you might get 35MPG at 55MPH.
On a long run I did long ago... I got 24.4MPG average on a 800 miles run... but that got stops... and went into city a bit and back out... could have been about 25 or so if all highway and this is on a 540l. I guess the average speed for the trip was around 70 MPH.

My EAT chipped 525i with autotrans has done between 35 and 36 US MPG at 55mph before. I don't remember if it was because I had put 87octane in, but wouldn't be surprised if that was the case.
"our cars are about as aerodynamic as a brick"
This is the case. The drag coefficient of an e34 is 0.30 or 0.32 (can't remember which), that is damn low, as they have a decent tail-design, flush windows and the rest is very neatly done to meet the wind tunnel tests when they were the main vogue.
