Currently I'm getting 42-45mpg on about 75% highway driving. In summer I can get 48-50. I'm about to try out some new low rolling resistance tires, I'm hoping for 50mpg
I've driven the car 2300 miles so far and I've gotten 35 mpg (drove like 70% city) in a tank, and as high as 41 mpg on 80% hwy driving per tank. It's my daily driver but I'm sure I can get 45 mpg on a long road trip with 99% hwy driving.
