At the start of my 13,303 KM US road trip Computer Standing was at 10.5 L/100 KM. At the end of my road trip (Ontario, Canada ---> Flagstaff, AZ ----->Las Vegas ----> Mohave Dessert -----> Napa Valley, CA ----> Santa Cruz, CA. -----> LA, CA -----> along US 1 and 101 up the coast -----> Portland, OR. ------> Mount Ruschmore -----> then back to Ontario, Canada via Chicago, IL) the Computer readout after the trip was 8.6 L / 100 KM.
I estimate 85% driving at 75 MPH / 120 KM/Hr and 15% at lower speeds in towns and cities.
You will find that it starts to lower as you drive longer distances. In my case it went gradually to the lowest reading above after around 8,000 KM
Hope this helps.
UPDATE ... this was with my sDrive Z4 3.5is ... just to clarefy since I now drive an M3
