Don't expect to get the listed fuel mileage ever, that is under ideal conditions, and in the real world ideal never happens. The fuel mileage should get better after the first oil change. I would expect that vehicle to be 22 in city and about 32 on the highway.

I usually get pretty close to the highway mpg number when driving with a very light foot. Our Infiniti will actually beat the highway number by 2 mpg. Subaru might need some break-in time. Maybe it will improve for you soon.

I owned a Honda Insight before this and always obtained the mileage the company told me it would get--so, never say never. 22/32 is the best I have obtained from the Subaru with very light foot driving. Thanks for the input. I did not expect the exact specified MPG but I did rather expect closer than this.

It is interesting than the closest iteration of the larger 2.5i, the Legacy Sedan w/ CVT, gets the same real world mpg as the smaller Imp's 2.0. My guess is that it's partially because the larger Leg's body actually has lower high speed drag. Conversely, the smaller Imp's 2.0 needs to rev up more to generate enough torque to overcome inertia at lower speeds. Another hint of this loss of efficiency (?) is that the 5speed manual Imp nearly matches the CVT efficiency, whereas this is definitely NOT the case with the manual trans 2.5i. Interesting, with one result that Subie's choice to use the underpowered 2.0 in the heavier CrossTrek version of the Imp is especially imprudent.
