You are in the Subaru Impreza
What is this discussion about?

Wow, the numbers are so different for ex: 08-09 Impreza vs Legacy. I have an 08 Legacy auto my first highway trip w/ 200 miles on odometer was 33.5mpg. That's doing the calculations myself, not trip computer. This was not summer and I've even consistently had 32-33 on highway trip in winter w/ snow tires. Cruise set at 65mph at all times. City driving not so good though, avg. 22 mpg. in all weather. I'm wondering if I can still get good numbers w/ the 2010 Impreza 2.5 auto? I'm optimistic. I do agree, Subaru needs to make more fuel efficient vehicles. I've looked at others prius, versa, yaris,fit but they don't do anything for me. I'll take a hit for gas mileage, cause I love the fun of scoobie's.

They're improving. Look at the EPA numbers for the 2010 Legacy 2.5i.
Not just EPA, either. In Consumer Reports both the 4 cylinder and H6 models actually got BETTER mileage than the similar Honda Accord.

I'm getting better mileage without the CVT in my 2008 Legacy. My concern that I see posted is with the Impreza mileage as I'm considering purchasing the 2010 model. Hoping to get equal or better than my Legacy.

No; I wish! If they offered a manual version of the XT, I would have considered it.
The mileage on mine goes all over the place given the duality of our using it. It seems like it either sees extended periods of short trips (yielding poor mileage as cited above) or mostly highway driving with very little of the short trips / stop & go mixed in. I am in Palmer right now, and we averaged ~25.5 coming down from Fairbanks today. I think that is okay given the winter fuel blend and snowy/slushy roads we encountered over much of the 330 miles. This was driving mostly 65-70 save for curves and other prudent places to slow down.

Just to clarify, I can get 33-34 mpg on a highway trip too. The numbers I am reporting for my OBS are mixed suburban driving. I mostly don't sit in stop and go traffic as I don't commute in it, but apart from that it is used for lots of shorter trips and 65 mph driving on the freeway for 10 and 20 miles at a stretch.
The 5-speed OBS used to be rated 22/29 prior to the 2008 dumbing-down of the EPA ratings, and so I just assumed I would be able to average 29 mpg in this car in my normal driving, as that has always been the case in the past.
And I am close at 28, but no cigar.
OTOH, I DID make 29 mpg in the latest tank: 356 miles, 12.3 gallons. Now if only I could keep it up on a regular basis....

I've looked thorough all the postings and couldn't get an accurate idea of what the mpg's were. It's listed as 20 city/27hgwy. Could you please post separate city and hgwy miles. This is greatly appreciated! I'm trying to see if the Impreza is better than my 08 Legacy auto before I make the purchase.

last night: 355 miles, 12.6 gallons. Just can't break those 28 blues. :-/
'09 OBS 5-speed
rebel: isn't it essentially the identical powertrain, except the new Impreza makes 5 more horses from the same engine? And the two models are within 100 pounds of each other weight-wise, and it's the same 4EAT you already have in your Legacy. Any improvements in mpg you experienced would be in the fractions of an mpg, I would think.

Really, given the driving conditions, your economy sounds pretty good. A close friend of mine just purchased a '10 Impreza 5-speed. She lives a ways "out in the country," so much of her drive is highway miles and her trips tend to be long (~30 miles or more one way). She said that her average fuel economy thus far (about 1500 miles on the car) is 30. I suspect that during the summer she may see as good as 34, but who knows?
I have been nursing my '10 Forester the last few days (since I got to fill it and drive it on consecutive trips) and it is reading 27 mpg after 70 miles. After the first trip upon the refill, when the engine was still warm, it was reading 31.9. Cold starts (when cold = 5 degrees!) really hammer the fuel economy, even when it is not allowed to idle! I would say the driving is, like yours, "suburban."

75-80 mph on the highway will definitely kill your mileage in a stick-shift Impreza... All my 30 mpg tanks have been commuting to work, where the interstate speed limit is 55 (which means 60-70, mostly..).
When I get the chance to put real highway miles on it, where the speed limits are 65-70 (real speed 75-80), my mileage starts dropping quickly.. 27 mpg is about the best I can do at those speeds...

have made me feel better, so thanks!
I rarely take it over 70, on the freeway I'm a speed limit guy exactly BECAUSE of the fuel economy gains that brings.
But I do have plenty of cold starts in each tank of gas, and I heartily agree that in this car (and I guess in most) they are a fuel economy killer, even during the warmer parts of the year.
My MPG readout always starts out like yours, xwesx: reading 32 or more after the first trip or two. But by the time 10 days have gone by and the tank is well below half full, it has dropped into the high 20s.
And the dashboard readout is still reading 1.5 mpg too high. 29.4 is one of its favorite numbers, and the actual mpg is very reliably 28 on the nose.
