worst thing about this car - a smaller car but average is about 22-24 average. Plus with tank range of 250 miles, you will be filling up often see full Scion xB review

For a 4 cylinder vehicle, the mpg could be better. (How about a 6th gear Scion!?). I average between 24-28, have gotten over 30 at times. Gas mileage is alright if you stay under 70mph on the interstate/highways. I actually get the best mileage in town see full Scion xB review

I expect better than 30mpg for a small car like this. Needs a taller 5th gear, or a 6th gear. see full Scion xB review

Best that can be said is that fuel economy is average for car of its weight and engine displacement. Automatic transmission only available in 4sp w/OD. A 5 or 6 speed tranny would be better. see full Scion xB review
