I am looking forward to a several hundred mile trip in it. I have seem posts here that 55mph seems to be the sweet spot? As I am driving in the city, I keep monitoring the AVG mileage indicator and notice if I am careful I can make it increase by a tenth or so. Once in a while I mash it and can see it go down.If 90% of your mileage is in the city, I would say that you are doing quite well. You should be able to get within the 27+mpg range on long trips. Spring and fall, when you don't have to use the A/C, will probably bring even better long trip mileage. One of the few vehicles that can beat EPA highway ratings if you try.
