For just under 17000 miles, I have averaged 35.3 using Fuelly. I just returned from a 5100 mile trip from NC, driving the byways of Vermont, Acadia NP in Maine, Quebec City in Canada, Sault Ste. Marie, Canada, upper Michigan, 3 days in Wisconsin, 2 days in Iowa, 8 days in Nebraska, and back to NC. Most interstate was 65MPH, much of the byways were in lower gears due to the sharp curves, and hills, and there was in-town driving in all the places I stayed more than 1 day. For the 5100 mile trip, using my gas receipts, not my trip computer, I averaged 39.02MPG. Driving 65MPH on the interstate, I get 41-43MPG, the same as I got in my Mazda2! I am thrilled with my mileage. The biggest dropoff has been in-town driving with the AC on, which is to be expected. The seats are so comfortable, that I was never uncomfortable during the 5100 mile trip, even during the 810 mile/14.5 hour first day. The handling on the byways was great(my other car is a Miata). This is the best road car I have ever had.
