MPG: Mustang V6 vs STI ?

[Mechoption]

Couldn't a stock 305 hp STI driving around at 43.9 mph get better mileage than this Mustang? http://green.autoblog.com/2010/06/24...-48-5-mpg-w-v/

Yes it can. These tests are always made in a way to make the company's car look the best. Obviously it wasn't using 305 horses. Going at a constant speed that is the most fuel efficient for a certain vehicle then yeah you will get a real good MPG. Any car can do that.

if you did that in a STi just like that you may crack 33mpg.

I have a 2009 wrx non STI... One thing is for sure i didn't buy my subby to get 48 MPG at 43 MPH. I am lucky if i get 15 MPG the way i drive. i don't really speed, i just like getting to the speed limit quickly.

The few times i have tried to get good MPG i realized i had to keep the PSI at -20 to -10... and any time i got in to the positives my MPG dropped. The best i could do was 28-32 MPG.

Sweet, that's reassuring. I'm getting a 2011 WRX and I didn't want to lose my Civic Si's gas mileage.

What sort of mileage do Si's get in real world driving? We have many members here with standard WRX's who struggle to get better than 20mpg.

Unless you keep the RPM's around 2500 in the Subie, you're not going to match the Si's MPG. My '02 Si, averaged high 20's low 30's. My WRX, albeit an '04, averages around 25 mpg...and I'm lightfooted. Wait until you feel the torque in that '11. You won't want to keep it under 3k.

I'm sure this car wasn't all stock. They probably messed with the ecu at the very least. They don't just randomly do a test like this without having the upper edge.

[mangostick]

like all american cars its probably also geared stupid tall too.. so its barely turning over at lower speeds like that.

low rpm = good fuel mileage.


Keep in mind too for real world, you'd be hard pressed to get same from a awd that you would from a f or rwd car.. again though, given that the stang is a heavy PIG.. it might balance out.

I'm not really a fan of any Mustangs made after 1970, but I love the glass roof on the 2011s.

OH lol you will trust me.

The ONLY way i get 28-29 MPG in my 09 WRX is on a 100% interstate freeway trip at 65-70 mph right after a fill up and no boost at all with the cruise control set.

You will be so addicted to boost you most likely wont see much over 25 mpg no matter how easy you think you are driving the car.

From the first time you ever took a WRX for a test drive would you really buy one for its fuel economy or because it is one of the most exciting cars you have ever driven. Be it in a straight line or the twistiest hilly roads, tarmac, gravel, dirt, a WRX can do it all.

They are addictive and like any addiction you need more.

Or is it just me ?

My name is not Lance Armstrong but you my friends can call me **** Legweak "can't you push that gas pedal any harder"
Don't be soft ****, harder, faster, more revs 4000rpm drop the clutch 5500 into 2nd 6000 into 3rd 6500 into 4th 7000 into 5th 180 kph bloody speed limiter Damn that Shelby Cobra was fast, i'll take you next time Muzzy.

They are truly addictive cars.

I have a 2008 Civic Si and I usually get 30-32mpg mostly highway driving. Spirited driving once in awhile included

I get 24-26 city:highway 80%:20%.
And I get 30-32 highway (70-75 mph).

I love my Si but some things changed so I got a 2011 WRX. My dad has it on his car lot but I can't drive it yet because he ****ed the front bumper loading it on a trailer. So I live 4 hours away from my parents and he calls me to tell me to drive down Friday and that the bumper would be ready... Well I get down there and he tells me the SWP paint didn't match.. So I leave my Si with my dad to keep the miles off it and drive my mom's Camry back up to school..

I feel like an old lady driving an automatic... The steering wheel is so big, it feels like I'm driving a sea-going vessel. The suspension is soft and the body roll is retarded. The seats are flat and non-bolstered so I feel like I could just slide into the passengers seat if I turn hard enough to the left. This experience has made me realize that I never want a non-sporty car. I would never give up my stiff suspension and overall connection with the car for something like a Camry. Sport>Luxury.

That being said; I will be getting my car this weekend. And what's even better is that my family is driving the WRX up to Tuscaloosa, AL and I'm meeting them from Starkville, MS then we're driving up to Cookville, TN to see some family friends. So I'll have 700+ miles on the car - already broken in - and Cookville is 2 hours from The Dragon. So I'll have a pretty fun Saturday.
