In both cases, we're getting slightly more than the EPA hwy figure with our old cars and way below the EPA hwy figure with the Impreza. Same commute routes. Same drivers.
I'm in the same boat & pissed about it. I guess I have no choice but to see what warmer temps/gas blends do for me... but this is ridiculous! No way my mpg is gonna go up by 10+ mpg this way. Right now I'm at 20/25. My older Acura that I beat EPA didn't take this kind of hit in the winter. No PZEV or AWD on that, but still.

People should probably relax about the MPGs until they get 3,000 - 5,000 miles on the odo.

Clearly, half of the posters here won't do that. Guess it's more fun for them to piss and moan.

I'm kinda surprised because, for the CVT, because I thought the front wheels are doing all the work until the rears are needed. So essentially you have a front wheel drive vehicle most of the time.

The most entertaining ones are the "I drive "feather footed" @ 85mph on the interstate. Why am I not getting 40mpg?"

I'm pretty sure from what I've read that Subaru's AWD system doesn't work this way. It is always on and delivering power to all wheels all of the time (some people have said it is 50/50 for the manuals and 60/40 for the auto/CVT transmissions), and that it can divert additional power when needed to a particular wheel if the car slips.

I can definitely tell the difference from my Honda element (having finally had some snow here), there is significantly less slip even with the stock all-season tires (I had general grabber A/T tires on the element which, while still all-season, had a more aggressive tread). I can tell that the AWD is always engaged vs at least the Honda system where front wheel slip needs to happen to engage the rear wheels.

The CVT system sends about 90% of the power to the front wheels when cruising. The other 10% is supposed to give better fuel economy than just dragging the rears along for the ride.

I've taken every opportunity to spin the tires, and I can't feel any lag in the system. When I do it in my driveway, all four tires spin at the same time.

No, it's not that way. It's a 60/40 split that can be managed by the multi-plate clutch. Here's the reference:

"Active torque split AWD
(Legacy, Outback, Impreza and Forester 4AT/Lineartronic models)

An AWD system developed exclusively for 4-speed automatic transmission, E-4AT (with manual mode) and Lineartronic models to maximise the reliable driving performance of AWD models under any driving conditions. The system usually distributes torque 60:40 front and rear. Sensors constantly monitor the vehicle's condition in areas such as changes in grip of the front and rear tyres or vehicle speed. The electronically controlled MP-T (Multi Plate Transfer) adjusts torque distribution to the front and rear tyres in real-time to suit driving conditions. This further increases the stability of the AWD system to deliver a safe and agile driving experience"

3rd tank fillup average was 24.6mpg, total average since 0 miles of 25.9, just over 700 miles on the odometer. It was a very cold week here in MN, windy too, so nothing unexpected. We went driving out to go tubing about 50 miles away, I refilled it on the way home. With the engine warmed up over the last 15.8 (after fillup) I managed to get the average up to 34.2, avg trip speed for the section just over 40mph over rather hilly roads, so once again, I'm still optimistic about the future for this car, have to say it!

FWIW I ran my handheld GPS (WPS, 3-d lock) against the odometer to see if there is much difference between what the odometer reads vs actual distance (this can vary based on tire size, in my case I'm running the stock tires on the sport premium 17" rims).

According to the GPS, the distance covered was 44.06 miles. According to the odometer the car traveled 43 miles (while I closely matched the start to a tenth on the odometer, I did reset when refueling and didn't watch to match the final tenth, so could be off +/- 2 tenths of a mile). Based on the straight numbers the odometer appears to be under reporting speed by about 2.4%, or actual miles traveled per 100 miles is 102.4 (possibly as much as 102.9 or as low as 102). No car is exactly correct and I am sure this is statistically within normal tolerances. This also means that my total mpg could be multiplied by 1.024 to arrive at a true mpg of 26.52. Again, FWIW, definitely not a scientific study, just some numbers to geek out over.

Just replaced my 09 Outback wagon with a 2012 Impreza Sport. I had been averaging 20-21 mpg with the Outback, so I'll be pretty happy if I can get in the upper 20s or low 30s with the Impreza after it breaks in.

We had 50* F temps here, yesterday, and my mileage jumped up. Where I'm normally at 30-35 at 60 mph, I was at 45-50! I think alot of the drag is caused by cold CVT oil-there's something like 10 quarts of it? That would also explain why the city-drivers are much lower than the long-distance drivers (whose oil has a chance to warm up).

I'm talking about this year's CVT. I think the above would apply to the manual transmission in the 2012.

Still on the first tank of fuel but right now the car is showing 29.6 mpg average with a 20/80 city/highway commute on a ISP/CVT.

It seems like almost everyone complaining about their mileage has the cvt. I've been gettingg 25-29 city and 30-34 highway with my 5speed hatch. And that is me not "feather footing" it at all. I drive like a 16 year old with a brand new corvette.

Just filled up my gas tank for the first time, after buying our Sport Premium CVT last Monday. With 330 miles of mixed driving, mostly city, it returned 30.5 mpg actual (miles driven/gallons pumped), not the computer. I'm pretty happy with that, given that my 09 Outback averaged 20-22 for similar driving.

First tank of fuel......1/4 tank left when I filled up. Lie-o-meter in the dash was saying 27.4. My math computed 24.8. Big difference if ya ask me.

I have noticed that mine is severely influenced by the cold & I've played around to test it a bit. I expect it to improve after break-in, first oil change but especially when the winter blend gas goes away & with warmer temps.

If I fill up when the car is warm & get on a highway, my trip gauge can get up to 34.5 mpg (which I know it's a 1-2 mpg generous based on my actual calculations). Then when I got off the highway, my city streets to home (about 10 blocks) brought it down to 31.8. I had figured & been told using the remote starter would idle the car, eat gas & lower mpg. True. Gauge drops to 29.5 MPG just from the 2 minute warm up. But here's where my tests have come up.... I've watched this on last 2 tanks to test my theories. So, when I try to give the car only 2 minutes or so warm up, or none at all, after being parked in 30 degree weather overnight (not very cold for our normal, but still cold for the engine) & I get in the car to drive away, the blue temp gauge is still lit, but it takes me 10 blocks city to get back to the highway, so it warms up the rest of those blocks' drive. This brings the avg MPG those same city blocks down to as low as 18 MPG on the gauge. By the time I get to work the highway drive brings it up to just under 21 MPG on the gauge. So, after seeing this cold drive bringing the MPGs down so much & my average down so low, I decided to do the remote start for a good 5-6 minutes so the temp gauge is no longer lit when I pull away & the car is warmed up. This trip then brings my average MPG up more than the last. Each time I do this it brings my ave MPG up more instead of leveling off between 20-21 MPG if I try to avoid the longer warm up. So I've tested it & I think the longer warm up & pulling away with the car warmed up eats less gas during that idle than driving away with the car cold. Just my theory... think what you will & don't mind the repetitiveness because I'm about to copy & paste this to the other 2 MPG threads.

2nd tank of gas. average temp of maybe 35 F. 33%city by time, but 20%city by mileage. That's generally conservative driving. Avg highway speed: 55-65.
MPG for 2nd tank: 30.5
oh - and that's miles driven divided by gallons, as read on pump method.

Okay, I sucked it up and drove miss daisy no more than 60mph (65 very brief periods to pass) 95% hwy, and got 31mpg avg on trip comp, 29mpg when i divided trip miles by gas used. not too bad but it was tough to drive like that. I have 4k miles on this thing. Gonna try 55 mph this week.

Default Model weight differences impact?

New user here. Just ordered a Sport Limited due in April. Buying the car to be our primary city commuter. Our '06 Pilot at 14 mpg just isn't cutting it anymore!

Anyway has anyone noticed any difference in the stated mpg of the IMP model by model? According to the reviews I've read they cut 110 pounds off the '11 model which is part of the reason for the mpg gain. It's obviously not the only reason for the improvement but I would be curious if Sport Limited's at 3,086 pounds don't get near the 28/36 while the 110 pound lighter base models do.

Does Subaru get to just submit one of the models from the lineup for testing and EPA validation or do they have to submit all models in the Impreza line?

I have a sport premium, and while I would not expect it to be 36 I would still expect an improvement overall. So far, I am disappointed in the mileage. Everything else makes me happy, but I am not happy about the mileage.
