My normal daily driving has very little freeway miles, and I tend to be in sport mode most the time and a little heavy footed (well ok, a lot heavy footed). I?ve been getting 17 to 18 mpg. However, I?ve taken a couple mostly all freeway long trips recently and dang, I got 28 mpg in comfort mode and 32 mpg in eco. Btw, what a great comfortable car on long trips.
