Year	Body/Powertrain	Comment
2015	4dr Hatch 158-horsepower 2.4L I4 5-speed manual FWD	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
2011	4dr Hatch 158-horsepower 2.4L I4 5-speed manual FWD	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

2010	4dr Hatch 158-horsepower 2.4L I4 5-speed manual FWD	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
2009	4dr Hatch 158-horsepower 2.4L I4 4-speed shiftable automatic FWD	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
2008	4dr Hatch 158-horsepower 2.4L I4 4-speed shiftable automatic FWD	could be better. I avg between 25-30mpg per tank...depending on how much city driving I do. see full Scion xB review
