we average about 15 - 16 MPG with 65% hwy 35% stop-n-go. We can get 17 - 18MPG when we take road trips.

19mpg is 7.7km/l in city courses, right? I don't think so... Mine does 5.7~6.0 km/l (4.8is 360hp)

19mpg is about 8.08km/L
I get about 15mpg which is 6.38km/L

My 06 3.0i does 5.7 kilometers per liter or 16 miles per Euro gallon or 13.5 miles per U.S. gallon . To confusing with different size gallons in different continents .

06 4.8is
 

I am getting (hand or OBC) 19.74 average and have been since I've owned it. I love mine.

I am wondering what the E70's get in similar config's?

I get 21 to 23 :D on long road trips, I set the cruise at 73 to 74 and go. I have been very happy! I generally get better than most of my friends or ex-wives, or alike. I have a tednancy to be pretty mellow...!

I abuse my race car, no need to do it to my X.

I have a 3.0 and seem to get the exact same mileage from 70 to 77mph which is 22 to 23 depending on wind. 17.5 to 18 is all the better I can get in city driving. 92000 miles on her as well.

Kept the speed anywhere around 75-85mph highway. Got 140 miles on a quarter tank of gas. :thumbup:

'02 4.4i - 14mpg mixed (mostly city, aggressively), 18mpg on cruise 65mph.
