Ouch! The 1 to 2 mile commute is the problem for sure. Over a year ago I read in the Toyota Prius Forum the somebody there had a similar issue. The Prius returned something like 22 mpg for their 4 mile commute. The commute was too short for the engine to warm-up and for the batteries to charge.
Subaru posts numbers on the sticker based on EPA tests. These tests are a standard that all manufacturer's are supposed to use. So unless Subaru faked the tests, they aren't lying about the MPG. Should the EPA have a wider range of tests? Certainly. Maybe 4 tests like "short trip", "city", "highway", "highspeed". That way they would fit a wider range of driving styles.

I just returned from a 2200 mile road trip, and the Impreza IS capable of the epa numbers and more. The 950 mile return trip got a 41.4 average readout ( 39 actual) Trick is you have to keep it at 60 or under! The temp was mid 30's and no high winds. Conditions were mostly flat but rain and light snow.
PS, I also did some awd driving in 8 inghes of snow in a Target parking lot and had a blast!

hmmm...watch that 8" of "snow plowing" with the front spoiler. You'll get some body damage that way.

Yeah, I got my first body damage on my 2012 Impreza when the corner of the front bumper hit a snow drift that was a little taller (and harder) than I thought as I was making a right turn. Crunched the underside on that corner, but its not that obvious. The Impreza is not a very good snow plow. Handles well on ice and in the snow, though, so long as the snow isn't too deep. Glad to know the EPA rating is possible. Perhaps my abysmal numbers will start to get better as I get more miles on it and warm weather returns. I'm not driving below the speed limit though. The on-road travel I do is mostly long hauls and I don't want to make them any longer.

That long front overhang is my only gripe. Living in a hilly region, I've barked that thing about once a month on pavement when I try to turn onto a steep street. And I actually can't pull straight out of my driveway at all; I just bottom out. A VW and a Mazda never had that problem. If anyone knows a good source for a different front spoiler (and maybe a way to add about an inch to the ride?) I would love to hear about it.

I was lucky and had no damage, and won't try it again. I guess that's why they came out with the Crosstrek.

Add some clearance? No problem... it's called XV.

This winter in MN, been getting around 27 mpg combined on my 2012 Sport Premium. It's mostly highway driving. On long--200 mi road trips, best I could do was around 31 mpg at 60 mph sustained speeds. In the summer, I was able to get 38-42 mpg consistently on long road trips at 60. Cold air, a few minutes at idle to warm it up, winter gas mix, it all adds up to about a 33% reduction in mpg for me.

33%. Yeah, it sounds insane, but that's on par with what I see in my Forester: About 25-30%. It really all depends on how cold it is and how short the trips are. When I used a Subaru for commuting, it was 30% or more. My wife tends to use our Subaru now, and she does multiple things with it or shorter round trips wherein the car is "warm" the whole of the trip rather than going to work and then home ten hours later when it is stone cold again.
By comparison, my FWD cars tend to lose about 20% of fuel economy during the winter when used as commuters.

I have also kept a complete log of all my fill-ups and have zeroed out my trip odo at each so I can calculate actual mpg instead of relying on the instrumentation which I find to be higher by about 7-8%.
I've driven my 13 Sport Premium about 6000 miles now (mostly city) and have been averaging only 24.5mpg. However, I noticed that since I hit 5500 miles, my mpg has started inching upwards. The last two fill-ups have netted me 26 and 27.8 mpg. I have not changed anything except for adding 1psi to both front (33) and rear (31) tires.
Somewhere earlier on this thread, I think, somebody who complained to their Subaru dealer about poor mileage was told to wait until their car got to a certain mileage before their fuel economy started to improve.
So other than my experimentation with the increase in tire pressure, does anyone think there is something to what the Subaru dealer told the other guy? Has anyone had the same/similar experience? I find it a little difficult to believe that 1psi in tire pressure can make that much of a difference.
