For the 2011 Subaru Impreza 2.5i, or the non turbo version, the mpg is bad for the size of the engine. A 2.5 liter 4 cyl engine. The power that the car has is also lacking with very little modifications that may be done to the car. The car also has become quite uncomfortable to sit in. As the only driver at 6'0" 186 Lbs, the seats do not support me very well. Pros, all wheel drive. The all wheel drive is the only thing I enjoy about this car since I live in North Eastern North Dakota. It gets very cold and icy here.
