A. Depends on which gas grade you are using
B. Depends on how heavy of a left foot you are using
If you have a heavier foot, you'll never hit the MPG the vehicle is rated for. Also, harder to hit if your state allows for 70mph or higher. So far, in my non-turbo (NA) I've managed to hit MPG consistently going 70mph. Anything over that, the mpg drops into the mid to upper 20s. City has been OK. Nothing less than 22mpg. Overall, for its size and weight, this car does pretty well mpg wise and the range is acceptable (350-400miles regularly on 87 octane).
