Yep, drag is proportional to speed squared. So when you figure the power neccesary to overcome that, you multiply by velocity again. So drag horsepower is a cubed funtion of speed.

So...theoreticaly, wind drag is 45% higher if you travel at 85mph rather than at 75mph

I suggest thinking of g-forces as returns on a gasoline based investment

I tried shifting at 3... but when all I do is city driving it takes me twice as long to get anywhere... lol. But then again when I spool at 2k and max at 3k I'm kinda screwed anyway huh.

After my recent second vehicle purchase (see profile at left) I have new appreciation for the relative economy of the WRX.
It's not an econobox and there really isn't any way to make it one. The low compression makes it less efficient off-boost, and we know what happens on-boost. Plus the added weight and drag from AWD.
If this concerns you that much you truly bought the wrong car.

I heard the toyota prius electric gets great mileage or maybe the volkswagon turbo diesel.

I've heard the GM/Saturn EV1 gets great gas mileage, and they're just crunching them right now.

Already been crunched. They were only allowed to be leased out for two to three years.

Been inside one, definately has that Saturn feel but a very funky interior.

What performance car gets good milage? If you really want to try and get milage off it try getting an AP and using the fuel economy map. Be warned though you can't step on it as it makes the engine run leaner. But seriously- who gets a performance car then cries about fuel economy? Go buy an 86/87 bmw 325es as your beater car if you want a cheap econo car(i swear that thing gives ~40mpg at 70mph- it's completely nuts) and keep the WRX as your joy car. This way you keep the high miles off it, get the milage you seek and beat up a cheap car. It's pretty much win win for you that way.

I am seriously considering selling my car... even though I love my car...

why do you have a wrx to begin with? a cheap bastard like you should be driving a POS prius and leave that car for someone more enthusiastic about cars/their car.

you're both sad and a disgrace. you're the kind of wuss person that people look at and throw stereotypes that sti/evo/wrx drivers are short skinny nerdy
fruits who can't drive. grow up and get in a civic, where you belong.

First and foremost, all you folks giving advice on how this guy can improve mileage need to understand a couple things:
CA gas sucks in terms of gas mileage, and the guy lives in San Francisco. Driving off boost is not an option on the hills around here. The hills are too steep and the traffic is too crazy. Hell, my Civic only got about 26 mpg in the city.

Finally, and probably most importantly, did you really expect a 227 horsepower, awd car to get great mileage?

In all seriousness, consider the relatively small amount you'll save on fuel compared to the cost of getting rid of your Subaru and buying a TDi or Prius...

ROFL. I'm lucky to get 230 miles out of a tank, even if I exercise some control over my lead foot. But it's worth every penny.

As others have stated, fuel cost isn't that much (currently) and the depreciation hit you'll take means saving a LOT of fuel... not happening unless you get a totally boring car, which probably isn't your bag if you bought a WRX.

I'm getting about 27.5mpg right now, and my 4cyl camry used to get about 31 or so. It's not great, but I wouldn't call it a guzzler.

I average 30 mpg with all highway miles. But most of the time, I turn into Lead Foot so my gas milage goes down the drain. Don't buy a performance car and complain about MPG!

30 highway ~23 city with a moderatly heavy foot. Please do the math before complaining about premium gas..... if you fill the tank when it's completely empty your paying $2.50 to $3.00 more than using the low grade.

My wrx has been able to get 300 miles per tank before the orange light comes on. It's a mixture of 60% freeway and 40% driving. Of course that is I actually went through a full tank of gas without gunning it. All I have for performance is an hks uppipe and no spare tire.

Almost 230 mi a tank before the empty light comes on so about 260 mi minimum in wrx so far and that was with a boost controller set to 15.2 psi.

Cant wait to start counting with real EM and a little more foot to the pedal.
