I just refilled the gas and reset the trip odometer/MPG monitor. Have driven maybe 5 miles since and it's saying I am now down to about 11 MPG. Before the reset I had dropped to about 18.5 MPG, mostly city and short trips and with AC on (I live in the south). I am going to take a long trip in a couple weeks, mostly on highway, and will be curious to see what kind of MPG I get. Then I will be back to the dealer to talk to them about this. If MPG doesn't improve, I am going to have a serious chat with Subaru. I sold my 97 Civic that got 38 MPG on the highway and decent city MPG too and bought this car, which I wouldn't have done if the MPG was disclosed with numbers like I am getting. Other than the MPG, I like the car.

AC on will not help your highway gas mileage. AC may not hurt as much as having the windows wide open. Just running the vent and windows up is the best if the temperature allows it.

I hope you get better MPG with the highway trip. Many new cars today don't get good mileage with short trips (under 5miles). In the Prius forums one person was in the 25?? MPG range with their Prius just because of short trips. The engine never warms up and in the Prius case the battery doesn't have enough time to charge. Just because the blue light goes off doesn't mean everything is up to ideal perforamnce temperature.
#21 of 139 Poor mpg and dealer or corporate does nothing

i made a mistake of buying a 2012 subaru impreza and after many emails and calls nothing is being done.
My car has around 3600 on the clock and i drive mainly in the city, i get an average of 20 to 21 mpg if im lucky and i drive 10 miles to work and 10 miles back.
I also do some highway trips and decided to let my wife borrow the car for a week to commute to work about 1 hour driving on the parkway to and 1 hour back.
The most we got out of the car is 27mpg which is 8 mpg lower than the estimate mpg for highway driving. The sad thing is my 2002 for focus which was old tired and had 115,000 on the clock was getting better mpg than my new car.
I honestly wish i had kept it now. Anyone have any suggestions or tricks or anyone having similar problems please feel free to post.

Consumer Reports tested a 2012 Impreza hatchback in the June 2012 issue and got 19mpg city, 33 mpg highway and overall average of 26mpg. How fast do you drive on highway? The EPA numbers are generally what can be expected if one follows the speed limit. Air conditioning will decrease mpg about 10%. Driver habits have the most effect on mpg.

Im usually driving around the 65 to 70 mpg on the parkway and around town im always at the speed limit due to the amount of police in the area. I also tested without the ac and it made a little improvement but no where near the epa estimates. Im glad its not just me with the poor millage and that its been tested by people who know what they are doing.
I got a freephone number to see what the buy out is on my lease and also if i can trade in my lease with someone else so they can take it over because im getting less mpg than my previous car and the reason i got this was for more mpg.

26mpg is good in that context. The Elantra only got 27mpg despite the 40mpg highway they tout.

Pay attention to the MPG gauge below the speedometer. You will then get a feel for how you need to drive the car to get the best MPG and you will also see that even a slight incline or press of the accelerator "kills" the MPG.
Before I bought my Sport Limited, I didn't realize there were so many hills in my area.
I've taken two 700+ mile round trips from Philly area to Boston area.
1st trip (2 people) - started with 1100 miles; PA/NJ turnpike, GW bridge, various NY parkways to Merritt Parkway to I-84. Drive up MPG = 36+ until the GW bridge, then continued to drop and ended at ~32 MPG (hills on the NY/CT parkways kill MPG). Return trip average = ~33 MPG. IIRC, A/C was on the entire trip.
2nd trip (1 person) - started with 5100 miles; mix of back roads, highway, back roads to I-84. Drive up MPG = 36+. Moonroof flipped up for 1/2 trip, A/C on other 1/2 trip. Return trip average = ~35 MPG. Heavier traffic, higher speed, A/C on more, back seats and cargo area full.
Normal commute = congested highway = ~30-32 MPG.
For comparison, my 2003 Outback 2.5L 4EAT averaged 28-30 MPG on highway trips and 22-24 on my commute.

There's no doubt the numbers are starkly improved over previous generations. In city driving, the start/stop behavior makes a big difference, especially with the AWD car for some reason. I notice that when I drive my Escort vs. my Forester, the relative impact on fuel economy in the Escort is lower when I'm a little quicker off the line (about 5-6%) versus my Forester, which is 10% or more. I really have to shift into "chill mode" when I'm driving the Forester if I want to eek out reasonable fuel economy. With a manual transmission, though, that isn't too hard to do.
I'm sorry that the original poster's fuel economy is so much lower than expected. I think he said a Focus was replaced by the Impreza... ? If so, it is entirely unrealistic to expect the Impreza to perform better on fuel economy in city driving. Heck, if it did better in the highway in identical conditions, I'd be quite surprised. You gave up some FE for the AWD. If you don't want or need the AWD, as in that was not a major consideration when deciding on the car, you did indeed lease the wrong car for your needs. The good news, though, is that you leased it.
