2010 Ford Edge AWD w/ 70,000 miles
Interstate trip between Washiington DC and New Haven, CT.......on I-95 doing about 70mph (not using cruise control). Average reading from trip computer was 27.2
I would no doubt achieved 28mpg if it weren't for 3 hours of nightmare traffic at certain parts. This is a replacement vehicle for a 1997 Oldsmobile Bravada AWD which never achieved anything better than 22 mpg on the highway. Couldn't be happier with the highway mileage.
