So your Impreza has the 4-speed automatic. That's why you're not satisfied with the mileage. 20MPG in city traffic is easily achievable with my dad's '10 Impreza hatchback with the dual-range 5-speed manual and the 2.0L engine, even with the E25 gasoline used in Brazil. It's not so unusual to break the 30MPG barrier with it in highway even with the air conditioneer on.

Ground clearance and the right tires are critical in the snow. Gearing and aerodynamics are key to good fuel economy. All my Corolla/Prizm cars have been very reliable and decent in the snow with just M&S radial tires. FE was 32mpg winter and 36mpg summer with the 5 spd.

Yeah, mine is the 4AT, which absolutely sucks. Realistically my average In the city isn't horrible, (around 22 if I baby it and use slight hypermiling techniques like shifting to nuetral). Considering that most of the speed limits around where I live are 35-40mph, I can usually keep my car under about 1500rpm in the city with it being in fourth gear. But as soon as I get above 60 my mpg goes down a bit, and 70mph it's just horrible. Where it's only a four speed it struggles at about 3000rpm on the highway (~65mph) and tends to go up to about 3250-3500 when I go up some of the steeper hills around here.

I went on a small trip today (65 miles) and used a few hypermiling techniques and was able to get 26.7mpg consistently at about 55mph on back roads, but it would drop to about 24mpg on the highway.

My subie is also the 2.5L, and I use plus grade gasoline. (89 octane, I believe). When using regular, my average mpg is usually 1-2mpg less.

I wouldn't mind getting 32mpg during the winter at all. I was only getting about 17mpg this winter in my car. I've also been looking at the newer corollas (I think they look amazing, but the 132hp at the crank is kinda steering me away from them...)

Also, I had a stopped up cat/bad o2 sensors over the winter, which probably significantly decreased my mpg, I replaced everything myself when it started to warm up and I've been getting ~23 average (mostly city)

If you wouldn't mind to get rid of the AWD you won't feel really so disappointed with the Corolla, as long as you get one with the CVT.

I just broke the 30mpg barrier with my 2001 Outback 2.5 with the 4at. Done by using country roads with limits of 45 mph (I'm usually doing 35-45 or about 1500 rpm is my target) and using techniques like letting off gas a little to get auto to up shift and coasting in neutral, air up the tires too, I run mine at 42 psi (45 is max for my tire). My commute is usually during low traffic hours so I don't have to worry about other drivers all that much.

Until I can figure out what I want exactly, I'm going to focus on squeezing every bit of mpg out of the subie. I need new tires, so I'm going to try to get something that'll be decent in snow, and a little but more efficient. (Currently have firestone tires at about 30psi, would pump them up to about 40 but the roads in wv are torn to pieces from salting the roads this winter). I've also been trying the P&G technique and it works pretty well. EOC isn't something I like though, tried it and power steering gets locked up pretty easy, so I'm just gonna stick with P&G lol

I was able to get mid 30's highway and mid 20's city with a 2000 4EAT 2.5 Outback.

Here is the log:

2000 Subaru Outback Gas Mileage (Lesbaru) - EcoModder.com

The biggest improvements were LRR tires, front grill block, wheel blocks, and of course the nut behind the wheel.

If I could get 35+mpg highway I'd be satisfied with my Subaru, but that's a somewhat unrealistic goal. I've actually been looking at threads for the grill blocks, and some of them actually look pretty cool, but I'm not sure if I'm willing to do it to my car lolol. It's an average of like an extra 2% increase or so isn't it? I may have to try mocking it up with cardboard and see if it'll make a difference. Also, I'd rather do it in behind the grille (I think it'd look a bit cleaner) but from what I've read if it's behind the grill it won't make much of a difference will it?

Also, here are some pics of the Subaru (the jetta belongs to one of my friends who drives like an idiot (130 cruising on the interstate). They were taken last summer when we drove about 300miles on Route 60 through WV. He ended up averaging like 13mpg, and I got about 26 (IIRC) with some decently heavy driving at times, the speed limit was 55mph for the most part, so it was a perfect speed for mpg lol







My old Civic Si, averaged about 40mpg highway at ~67mph.







The T/A I DD'd two winters ago (~9mpg, on a good day)



Wow.. That was quite a few pictures... My bad... These are only like 3 of the 9 cars I've owned lolol.
