I am getting the impression that the respectable, if not EPA rating, freeway gas mileage is masking just how bad this car is for around the town gas mileage.
I see lots of discussion of rolling out some decent gas mileage under ideal Freeway conditions on a nice sunny day, but I am not seeing ANY mention of scrutinizing JUST city driving without a boost in the numbers from highway. The Impreza with CVT is rated at 27mpg CITY. How many people, if any, have gotten better than 20mpg CITY without boosting the number with some freeway driving? Thats 25% under EPA rating, which should not be hard to hit with sloppy driving, pre-break-in, winter gas....you would think. My CVT PZEV hatchback is showing 14-15 mpg city. Thats 48% UNDER EPA RATING. Hard to believe a bit of break in and summer gas is going to bring that up anywhere close. I am REALLY hoping to be proved wrong, but its hard to imagine. I am getting roughly 28mpg freeway, which I suspect will come up a MPG or two over time to maybe 30mpg or so, which is "only" 17% under EPA, but is something I can live with. Unfortunately this is my wife's car and she does mostly city driving.

Thom, you keep posting the same thing, but I think you're missing the definition of 'city' driving as outlined by the EPA. It is a strict test, defined here:
http://www.fueleconomy.gov/feg/fe_test_schedules.shtml The city MPG is arrived at by driving a specific route, 11 miles, from a cold start, over a 30 minute period with an average speed of 22MPH with 22 stops/starts. If all of your trips are shorter than this, and all from a cold start, you can't expect 27mpg, especially not when the car isn't broken in either. Also note that the city test doesn't consider the engine fully warmed until the last 10 minutes of the 'city' drive. I do think if you are taking extremely short trips in colder weather, the cold will have a more severe impact on your MPG in particular, and that with the engine starting at 85-90 degrees in the summer it will have a significant impact on mpgs for your particular scenario. Most see a 10-15% drop in the winter, I've experienced this with a dozen cars since I've owned one, but I wouldn't be surprised if those numbers are doubled or more if your driving scenarios are as you've described. |

quick update....about to rool 7K on the car....in for its 7500 mile oil change..(2d one) on the 16th....consistently rolling 30.x to 31 MPG per tank on 100 mile commute...80/20 hwy to city........would concur this little car gets low MPGs in short around town runs........but as my daily commuter......quite happy with it.......around my neck of the woods....MD outside of DC.....there are no short runs.....where I am at....any run is min 15-20 miles to get to places.......so no problem with warm up or short trips.....
fully expecting 31+ as we enter spring summer for the commute mileage |

In other words...NO, YOU are not doing better than even 20mpg city? which is 25% below EPA
![]() I never said I EXPECTED To get EPA. But getting 48% BELOW EPA seems to be aiming low UNDER ANY CONDITIONS. If this car is only going to get decent gas mileage in 85-90degF weather, thats about 2 days out of the year in the Northwest and seems to be an odd requirement for a car whose selling point is AWD good fuel economy. and 10-15% still doesn't add up to 25-48% shortfall. I keep posting the "same thing" because I am TRYING to figure out the seeming discrepancy in fuel economy numbers I am hearing. And I seem to be narrowing it down to this car being a little piggie when going to market. And I think if a car company is going to so grossly overstate one end of the spectrum of its selling point, people should be aware of that going into it. I just killed a sale for someone work, who would be mainly doing around town driving and was hoping to get significantly better mileage AROUND TOWN than his gas guzzling current SUV....not just up it a mile or two per gallon, buying a new much smaller car. People need to know what this will do REAL WORLD, so they can make an informed decision and not be bummed out later. If you want a freeway commuter, this is an AWESOME car, apparently especially if you want AWD in Florida or Arizona or South CA. Quote:

Have you talked with your dealer about this issue? I mean, cold starts and short trips are mpg killers, but to get 14-15 in Washington or Oregon is...surprising to me, since it's not that cold there, comparatively. |

First fill up this morning.
Majority of my driving is in city, some short trips, not too much highway driving (probably 75 total freeway miles at 60mph.) The weather in Seattle has been cooler the past week since I have had the car. 281.9 miles this tank 12.459 gallons Avg: 22.62 The trip computer said 22.5 when I filled up so the trip computer for me seems pretty accurate. Total mileage on car right now is 293 miles. |

The caps aren't really helping get your point across. Either something is wrong with your car, or you're simply the bottom of the bell curve - someone has to be. I know during the 1st 2-3 miles of my drive the pzev (not sure if you've got that or not) severely limits the effectiveness of the engine and appears to use significantly more gas as a result; after that it gets significantly better. If it is barely being driven past the cold engine light turning off, your mpgs are going to suck, plain and simple.
So you lost a sale to a co-worker because you aren't experiencing what you expected...why not point them to fuelly and say I'm not doing great, but it looks like the average is about 27mpg (on a bunch of mostly new vehicles that aren't broken in, during the winter) which is pretty damn good for an awd vehicle. |

I'm with the guys finding better mileage in the warmer weather. Strictly by trip computer, I've found 2-3 mpg better at least when the temp is over 45.

A couple comments before I ask a question. The EPA ratings for a CVT are city 27 and highway 36. The manual gets 2 miles less in each category I believe. Outside of a hybrid car, those are excellent numbers. There are people on the forum saying that the highway mileage masks the city mileage. They are two different numbers measuring two different things. They are not combined so stating that the highway masks the city mileage isn’t entirely true. Even if it was true, 27 city is extremely good. Let’s also keep in mind that this is an AWD vehicle which makes this is even more amazing. The CVT Impreza is the most fuel efficient car in the US so good luck finding a more efficient AWD vehicle. With that said also realize that it will be damn near impossible to get to the EPA ratings in most cars. Driving styles and real life driving make this impossible. Anyone on this forum live in NYC or drive through roads covered in potholes? You will probably have a hard time getting 27 mpg in the city. Now I am not saying that you need to drive like a grandma, but if you are getting 24ish mpg in the city, can you really complain? Chart your progress I know I am (you can find that in the thread called 2012 impreza gas mileage), and if you are finding that you are getting something out of the ordinary don’t worry about it.
I see people in this thread are saying that because of the winter, they are getting worse gas mileage. Some say it’s the gas and some say its driving on a cold engine. I do know that when I start my car everyday my car idles at around 2,000 rpms. If I drive for about a quarter mile, the car will start to idle at a normal speed. I heard this is normal, I am not sure why. They say it’s better to let the car naturally warm up for gas mileage. That high idle tends to make me worry though. My question is why are people finding worse gas mileage when it’s around 30 out in the winter then when it would be 80 in the summer? Cars are designed to run better on colder air. Colder air makes more power. Shouldn’t the car respond better to the colder air then the hotter air. I thought that methodology is part of the reason why the intakes usually take the air from the bottom of the engine, versus the top of the engine where it is colder. |

Colder air to a certain degree I am sure is a good thing, but it is the colder engine that is the major factor on trips under 10-15 miles in the winter. You can tell when the engine is settling into proper operating temperatures with most cars - the Impreza seems to take about 10-12 minutes on my commute, warming up around 8 miles into my 13 mile drive. Our Mercedes (which my wife usually drives) is barely warmed up when I get to work, every car is different.
Part of the problem with the EPA ratings is the assumption that if I drive in the city, I should get 27mpg. The reality is that the 'city' number is arrived at using a very specific defined test - while it does account for a cold start, it is an 11 mile drive averaging 22mph...the kind of city driving you'd achieve maybe in fargo, nd (been there, done that, haha), but definitely not a major urban area. The higher revs from experience (the Impreza is our 12th car in almost as many years) I would attribute to the cold engine - it won't do that in the summer (at least, not for nearly as long a period). The CVT I think might make it appear to be higher than a normal transmission because with a regular geared transmission you can force the car to rev lower by changing gears (at least with a stick you can). |

you are sounding like you are from the subaru Marketing dept.
![]() you entirely missed the point..... yes, city and highway are two different numbers. that was specifically my point. everyone seems to be focussing on the highway numbers and ignoring the city numbers, and using the mixed numbers to imply that its doing fine in the city. yes, 27mpg would be a very good mileage for an awd car in the city. heck, I was just hoping for 22-25 range in the city with that rating. the fact is, so far, no one seems to even be able to get above 20mpg city, which is 25% below the rated city number, and many people seem to be getting significantly less than even that....unless they jack up the numbers with "a little bit of highway driving" mixed in. imho, once you start mixing in freeway mileage, you should be comparing it to the epa mixed number of 30mpg. now maybe this car is going to jump up that 25%-48% difference once break-in, toasty weather and winter gas kick in. for the 2 weeks of toasy weather we get in the seattle area, that would be fantastic mileage. i am just finding it hard to believe it will come up that much and a couple of people that have 7000+ miles already seem to confirm we are talking a couple mpg with break in, not almost doubling. and by the way, my car sits in a relatively warm garage all night and seattle is hardly cold enough to be major impact. i am hoping i am wrong and it gets close to epa rating with "grandma" driving...eventually, because I hang onto cars a very long time and the die has been cast for me already.

Please don't say no one is getting even 20mpg city - on fuelly there are 48 cars, only 6 of them are under 24mpg and at least half of those haven't even had 5 fillups (one of which isn't properly calculated...they left off their miles traveled on 2 of 4 listed fillups). Of those 6, none are under 20mpg. If your numbers are true I would be completely 100% frustrated too - keep the data handy and if you're upto 2-3K miles without improvement take it to subaru. I briefly owned a hyundai accent a couple years ago (maybe 8-10 months), could barely get it above 30mpg even on road trips - took a massive dump on that trade in, won't make that mistake again. All I can reiterate is that I hope I am right about a coming change with break-in and warmer weather having a bigger impact on your driving scenario than most of us. |

This thread has over 140 posts. I am sorry if my post did not exactly relate to your post completely. It wasn't meant or intended to, so I am not sure if you can say that I "entirely missed the point." I do however think it is the other way around, and that you in fact missed the point. There have only been a handful of people who have actually posted their city mileage. What I consider city mileage might be different than what you consider mileage. I have never been to the west coast so I cant actually speak to what your city driving is like. Since I lived in NY my entire life, I can say that NYC city driving is different than Westchester city driving and Westchester city driving is different than Upstate New York city driving. People here are comparing apples to oranges. It is probably nearly impossible to say how many miles anyone is averaging in the city or highway. While I do understand your point that highway may skew the total numbers, but for what car isn't that the case. Here's one thing to also consider. According to the city EPA city test, the car is driven at 22mph. That is below most of the speed limits in NY. Alot of roads around me have a 35mph limit. Can you really expect to get 27mpg on the same test they use if you are driving at least 10mph faster? At the end of the day, the CVT combined mileage is about 29mpg. I have 700 miles on my car and if right now my car is averaging about 28 mpg, I am not going to cry. I wouldn't even be upset if I was getting 25mpg. I just hope it keeps improving just like anyone else. Last edited by jparker070; 03-10-2012 at 08:09 AM. |

Yes, I have been referred to Fuelly. Yes I have looked carefully at those numbers. I am an engineer. I am used to reading and interpreting data. Note that ALL those cars include a significant portion of highway driving in their estimated percentage loading. Depending on how you look at it, driving city really hammers your overall mileage, or driving freeway really brings up your overall mileage. None of those summaries are pure city driving or even close to it. and that is what I am referencing. Most people seem to be focussed on freewheeling highway numbers. since you brought up fuelly.... has anyone noticed the trends on the graphs that show the trend curves for each car with this very preliminary data? Besides swinging pretty wildly, I notice a weird slight trend of the gas mileage going down after the initial fillup. Way too early to put much weight in that. And it probably puts fuelly as a data source in question more than anything. Other people have already pointed out how a couple of "bad" entries have messed up the overall trends on other brands/models of cars on fuelly. You have to look at the fuelly numbers and graphs and individual charts very carefully for it to be of any use. I sure hope I start getting 10 mpg better fuel economy after break in, to at least get me to within striking distance of the EPA numbers. |

I'm curious if you've been keeping track of your average mph? Mine is in the low 30s, and I think that is the best general indicator of where your overall driving patterns fall. Other than that nobody can really say I drive all city or all highway, because everyone's interpretation is different.

You'll be surprised, and begin to understand why you're getting less mileage. Then look at comparible (well-there aren't any, but look at similar weight and engine size) cars on fuelly, and see how low -their- mileage is, too. Regarding the drop in mileage on later fuel-ups, it's obviously due to people starting to hammer on the car, instead of hypermiling it on the first couple drives. Same thing happened to me. In fact, I dropped avg MPG tonight from 32.2 to 28.1 by going from 55-85 at WOT, and then from 0-80 WOT on the drive home. I'm at a half-tank, so that's a huge jump (err-drop). In fact, it's the kind of drop I'm used to seeing from my turbo cars, where they go super-rich under high boost. On the plus side, the car is accelerating hard (for a heavy 2.0 NA), and I'm really loving it. Now if I can only get fixed/work past the TC lockup taking place at 35mph under normal accel, and instead, have it lockup at 20ish, I'll be thrilled. |

Thom52, what kind of average MPH is displayed on your wifes car? My last tank was 21 mph avg resulting in 25.2 mpg.
I notice when the car is cold (but blue temp light is off) rpms will always be 2000+ at city/suburban speeds. Once warm (which takes maybe 2-3 miles), those same speeds yield 1500 rpm and mpg jumps noticeably. Maybe this is attributed to emissions-focused programming where the CVT forces lower ratios and richer running until engine temp produces happy exhaust. I know that a 1.5 mile drive to the grocery and back never gets the car warm and mpg is a dismal 14-17. The sticker from my car says: EPA Fuel Economy Estimates City MPG 27, expected range for most drivers 22 to 32 mpg. Highway MPG 36, expected range for most drivers 29 to 43 mpg. |

When I went to order my Impreza 2 weeks ago, I took one out on a 20 minute test drive. One was on a 8 mile highway drive at 62mph and I achieved 42.1 mpg(that was according to the trip computer). After that I reset it and I got off the highway to head back to the dealership. That was a 2.9 mile trek. Trip computer said 29.7. I was very happy with that and that is another thing that sold me on the car. I obviously don't expect to get those number all the time, but it was impressive nonetheless. The car had 7 miles on it.
As far as the 2000k rpms when you start the car, that's normal. I had a 2011 Outback and it did the same thing. When I questioned the dealership, they said it was due to something with the PZEV emissions. There were quite a few people on the Outback forum that confirmed that. My mom has a 2012 Elantra that was bought back in November. It only has 900 miles on it as she really only goes to the store and very local trips. She is quick on the gas and hard on the brakes. For those of you that have considered the Elantra know it's rated at 29/40. Her average is 21.6. When I drive it in the city, I can eek out 26.9 and 35 on the highway. It seems that newer cars are very sensitive to how they are driven. Last edited by carlvr87; 03-10-2012 at 08:28 AM. |

I've driven 1000 miles 50% city (maximum speed 50 kph lots of traffic lights) and 50% highway (maximum speed 110 kph country side and Trans Canada) 5 spd- Average is 32 MPG. Weather temperature between minus 15 Celsius to plus 10 Celsius. I think the MPG will go up once summer is here.

I usually run a Thule roof rack on my 2.0 Sport manual PZEV. I took the rack off last week as I had to make 2 trips to Greensboro and wasn't going to have time to ride
. I haven't put it back on yet. I filled up Wed. night. My low fuel light came on this morning heading to work. It was the furthest distance I had ever traveled before it tripped on. So I decided to push it on my way home. I drove 1 exit past the point when the HUD went from 30mi DTE to "---". This was my normal commute that consists of 70% interstate and the rest consisting of city traffic and rolling back roads.![]() I haven't seen many other people posting pictures so I believe the gaunlet has been thrown! |
