I've been in Germany now for over a month. (Sorry for my delayed replies, I still don't have dsl at home yet) I haven't done any major measurements but I must say I don't see any really big change in mpg by driving fast. I switched my scangauge to metric so I have litres/100KMs. This is a good thing to do in any case because it stops fluctuating all over the place when set to mpg. (My mpg also improved going from RC3 to RC5.)
What I see on the scanguage is that when I am cruising at 80mph it shows 3.5L/100KMs, at 100mph 3.8L/100KMs and at 130mph 4.3L/100Kms. There is a slight increase obviously for the faster speed, but not enough to break the bank. (Obvioulsy there is more wind resistance but you are also clocking the kms in no time and cut short your travel time by half hour before you know it.) What I find that burns up fuel is the constant acceleration and braking. In that sense if you drive it like you stole it in the US on hwy, you have to constantly keep decelerating/braking because folks are moving into the left lane at 55mph when you are doing 90mph (ever driven in Florida? lol) or if you go far enough you get copped. Here the traffic really flows, most times the left lane is clear if there is not too much traffic. The end result is despite all the high speed driving I'm not seeing any overall mpg loss by driving in the >100mph speed range. I think I was burning more in Northeast due to different driving conditions. Of course in the midwest things would be different if you pulse and glide with nobody on the road, can't beat that.
