28.8mpg after a 3000 mile road trip in June. 2.0L turbo... A lot of highway miles. For what it's worth, I do use auto-stop/start and after this trip I cut off the front bumper plastic splash guards which are supposed to help with mileage.
I made a 2200 mile trip to OK and TX over the weekend, and on the return half, I was pulling a small trailer. My mileage averaged 19.7 over the 2200 miles. I just wish it had another 50 hp. In Texas hill country I spent most of my time in 4th or 5th gear. (6 spd manual)
