The commute in the GLA is ~8 miles on 35mph highway with 200ft elevation change, then another 8 miles on interstate. We're pretty happy with the mpg... much better than the 15mpg Touareg in the garage.Hey thank you for posting on Fuelly. The CLA numbers on there are what made me go ahead and order a GLA. Mine is supposed to be in tomorrow. I noticed on Fuelly you do not list the percent of driving city vs. highway. I lived in Corvallis and commuted to Eugene for a couple of years in the 80's. I am hoping for 30 mpg on my mostly 2 lane state highway commute. In my test drive I saw the mpg indicator go up to 47 briefly. What kind of roads do you drive?
