Default STi Gas Mileage?

Hey everyone,
I'm considering purchasing an STi and I was considering what kind of gas mileage it gets? Or for any other Impreza for that matter. Miles per gallon or miles per full tank? Mainly city or highway?
Thanks in advance.

That's so dependent on how a person drives, honestly. With my Wagon (lightly modded) , if you keep your foot in it, you can almost see the fuel needle moving. I know I get anywhere from 250-325 miles per tank.

It does depend on driving style.

I don't drive my car too harsh on a regular basis and I commute 13 miles each way, mostly on the highway. I average about 240 miles before it drops below 1/4 tank. I also commute pretty early in the day, so full on traffic jams are rare during my commute. I am sure it would get much worse if you experience stop and go traffic on a regular basis. I have gotten as much as 340 miles off of a full tank, but that was on a road trip with 99% highway driving and it was just about on the empty before I refueled. The light did not come on, but I am sure it would have in a few more miles.

I usually get around 24-25 miles per gallon. My commute is 40 miles a day mostly highway. I drive with the cruise on a lot, and I usually set it at around 65. I only drive fast on Sundays anymore.

if you're considering the STi and you've got concerns w/ gas mileage than you're buying the wrong car. I'd say you'd be lucky to get 19 mpg on mixed driving. City's around 17 and highway is pushing 21.

I have a daily commute of 18 miles, all city driving, with at least 2 miles of it in a downtown area with a stoplight every single block.

I rarely get above 50mph, and usually am doing good to hold 40mph. I cross 12 RR tracks going each way to work (that's a total of 24!) and it isn't at all unusual for me to sit for several minutes at least at one of them each and every day.

It's not unusual for me to use WOT on a sprint to 50mph at least 5 times a day, particularly if I'm first in line after the RR gates go up and I'm pissed. In traffic, in particular in the downtown area, I hold around 2500-3000RPM in a lower gear for several minutes at a time when I'm jockeying for position in traffic. All other times, I shift no later than 3000RPM, if not lower. And I typically use the A/C at least in the afternoon, if not all day.

If I'm in steady state traffic, not accelerating or decelerating or changing lanes, I typically try to hold the RPM's at 1500, but no lower or the engine bogs. I always rev-match (to the best of my ability) on downshifts unless I know I'm going to come to a complete stop.

All those factors considered, I typically see about 22-23 mpg. I have, on a couple of occasions, gotten 25 mpg, but I suspect I drove extremely conservatively those weeks.

At one point, I experimented with lowering my normal shift schedule such that I shifted as follows:

20mph > shift to 2nd
30mph > shift to 3rd
40mph > shift to 4th
50mph > shift to 5th
60mph > shift to 6th

That yielded an abyssmal 19mpg.

One of my co-workers also has an STi, and is a much more skilled driver than I. He has a much shorter commute, with mixed city/rural driving. He claims to shift no higher than 3000 RPM, yet he never averages any better than 19mpg.

I noted on Popular Mechanics recent article on the long term test of their STi (prior to it being stolen), they averaged 17mpg with a max of 21mpg. I assume they drove it like they stole it.

I think EPA estimates are 18 city and 24 hwy.

Dude, if you are gonna buy an Sti and are worried about mileage, might I suggest you get a Toyota Echo instead?

Just kiddin'

I've been keeping track of my mileage and it averages about 21 -23 mpg, I do mostly city driving...fairly aggressively. But yeah, if you floor it, you can see the needle heading south.

Well regarding gas mileage there are two things going against the STI. First it is performance car and secondly it is all wheel drive. I averaged 20 mpg with my STI. In comparison with my normally aspirated RS I get 29 mpg. The STI uses premium gas and the RS regular.
The STI can do better if you drive like a little old lady. Shifting at 3K and never passing anyone and staying at no faster then 55 I was able to get 25 mpg. But that is torture in an STI.

I have a WRX not the STi, manual tranny and I get 18.5mpg. Everytime I fill up it's pretty much the same....18-19mpg city. Highway I'm lucky to get 27mpg...more like 25-26mpg. Almost all of my driving is in city, short trips, and I don't pay much attention to gas conservation, fairly agressive driving but I would hardly say I wail on it. I'm impressed with all of your gas mileages, especially with the STi.

I know a couple people with the new Legacies with auto trannies (3.0 liter six and 2.5 liter turbo four) and they're lucky to get 15mpg with those in the city....consumer reports got 11mpg in city driving with the new legacy 2.5GT. Subaru's are not very gas friendly and I wouldn't be surprised if this hurts their sales for awhile with all the energy price jitters.

All things considered, for a car that puts out 300hp and 0-60 in under 5 seconds, these mpg numbers are pretty good. If we are comparing cars, maybe we should not compare a WRX or STi to regular cars. When compared with similiar preformance cars, Subarus average mpg in the very low 20's with most of the other performance tuned cars like 350z's, Evo's, Corvettes, etc.

I live in Seattle and work with people who pay about $5.00 a day for coffee drinks from Starbucks. Over the course of a year that runs them about $1,200.00 bucks! They could have brewed their own Java at home for about a dollar a day! Compared to that, I don't mind paying an extra $300.00 a year on gas for a car that gives me the same feeling and can get me from point A to point B as well. It all depends on what your prefrences in life are.

Yes, I believe it's 28 highway VS 24 highway for the STi. But the average for combined driving is 22 for the Corvette VS 20 for the STi, per the www.fueleconomy.gov website. (The very low 20's)

Mileage varies depending on your driving style. I've seen anywhere from 330 miles to a tank(light driving with short shifts) to a horrible 160 miles when driving hard. My Mustang 5.0 is the same way. It is possible to get good gas mileage, but these cars beg to be driven!

Default I jost got a record tank on my STI

I've had my STI since June. I've got just over 4,000 miles. Normally, I fill up at about 240 miles and it takes about 14 gallons which equates to 17.1 mpg. Then, a couple of weeks ago, I had disconected my battery and that next tank only got me 210 miles while sucking 13-1/2 gallons which is 15.5 mpg. (maybe caused by the ECU being reset?) My latest fill-up took 14 gallons and the odometer was at 260! I was happy to get an all-time high of 18.5 mpg! I do drive at a brisk pace and I bought the car becuase it performs. Maybe I'll be able to resist some day and get 20 mpg out of it?
