ccnelson2285 Posted May 29, 2012 Report Share Posted May 29, 2012 I purchased a beautiful 2012 Kona Blue GT500 - absolutely love the car, but not the MPG. I have kept careful manual records of MPG for several months, and I have consistently gotten just over 12 MPG with very conservative driving - mostly city, and a little highway. I have not even remotely achieved the lower end of the range advertised, which is 15 MPG in the city. I have called Ford's SVT department twice now inquiring if this seems strange, and they've told me the mileage should improve as the car ages (I have under 2k miles). What kind of mileage are others getting with their Shelby's? Can anyone confirm that my mileage of ~12MPG is out of the ordinary? Any advice? thanks!

07SGT4578 Posted May 29, 2012 Report Share Posted May 29, 2012 Who cares what the fuel economy is, it's a GT500. Drive it like you stole it. Buy a focus if you need good fuel economy. (null) Link to comment Share on other sites More sharing options...
goin2dirt Posted May 29, 2012 Report Share Posted May 29, 2012 I get in the 13's but like 07SGT said "who cares". It gets better MPG then any other supercar out there. Link to comment Share on other sites More sharing options...
verlyn12 Posted May 29, 2012 Report Share Posted May 29, 2012 Nearly all my driving is highway miles-averaging 22 with about 3500 miles on the 2012 500. This is about 75mph Link to comment Share on other sites More sharing options...
SSGT500 Posted May 29, 2012 Report Share Posted May 29, 2012 I had two problems with my 07 that adversely affected fuel mileage. My parking brake was adjusted too tight and the front end alignment had too much toe in. Link to comment Share on other sites More sharing options...
Ecrissman Posted May 29, 2012 Report Share Posted May 29, 2012 On the drive home from the dealers (all highway) I was around 22mpg. Other than that I never bothered looking. Link to comment Share on other sites More sharing options...
ccnelson2285 Posted May 30, 2012 Author Report Share Posted May 30, 2012 Thanks all. Not that I purchased a Shelby for Gas Mileage, but 12 MPG was a little alarming. It just reached over 13 (whoo hoo!) and I've been told that mileage will improve over time (still less than 2k miles). Link to comment Share on other sites More sharing options...

It just reached over 13 (whoo hoo!) and I've been told that mileage will improve over time (still less than 2k miles). If you don't reset your mileage calculator in your Drivers Information Center (DIC) it will show you the average mileage over the life of the car. So if you started with 2mpg it will take a long time to get it up past 12mpg. Try calculating your mileage "the old fashioned way", with a calculator and pump reading. You may have MUCH better gas mileage than you think. Unless you *did* reset the DIC mileage indicator already. I get pretty decent mileage both city & highway and mine is far from stock. It's ALL dependant on how far your right foot is from the floor, period, end of story, finito. Well, unless you have an ultra rich condition (stuck open injector, excessive fuel pressure, etc.).

Burning Blue Star IV Posted May 30, 2012 Report Share Posted May 30, 2012 What kind of mileage are others getting with their Shelby's? Can anyone confirm that my mileage of ~12MPG is out of the ordinary? Any advice? I average about 13.5 on the high end in all city - stop and go driving. If I get on it at all..it drops to high 12's. So I don't think it's that out of the ordinary for yours. Now, if you were doing 50 mile trips on highways...and got that - there would be a problem. I can get near 25mpg on highway trips.

sweenstang Posted May 31, 2012 Report Share Posted May 31, 2012 My milage improved a bit as the car broke in. I'm at 6K miles now. Getting 16mpg around suburbia here, low 20s on the highways, not that it would make much difference to me - I love driving this car no matter what! (Uh, unless rain is in the forecast or the temp is below freezing!) Fill 'er up and enjoy it! Good taste in color BTW. Link to comment Share on other sites More sharing options...
Kontra06 Posted May 31, 2012 Report Share Posted May 31, 2012 IF I pay attention to the shift arrow and IF I keep my foot out of the supercharger... I have gotten 21+ with a mix of some town and a lot of highway driving. If I spend time running around 'town' and making the 'charger whine... I get 14-15.

4Lights Posted May 31, 2012 Report Share Posted May 31, 2012 "Supercar"??? I think it's a pretty super car... I have 6k on the odo and currently averaging a calculated 18 mpg in mixed driving, I've even noticed the DIC mpg is pretty darn close - first car I've owned where it's not at least 1-2mpg off Link to comment Share on other sites More sharing options...
nshttpd Posted May 31, 2012 Report Share Posted May 31, 2012 I've got less than 2000 miles on my 2012 GT500 and it's been getting pretty decent mileage when not in "drive it like you stole it" mode. Being one of those "tech" people I use Fuelly to keep track of MPG's on the vehicles. Here is the Shelby : http://www.fuelly.com/driver/nshttpd/mustang The spike up to 21 MPG was highway driving (ATL to Barber Motorports Park and back) on I-20. -steve Link to comment Share on other sites More sharing options...
JeffIsHereToo Posted May 31, 2012 Report Share Posted May 31, 2012 No idea what your situation is but the big factor is your driving habits. In my case my gas mileage went WAY down from the SGT to the Boss. But after aging more attention I realized I was driving differently in the Boss. The Boss loves to rev high so you don't get the feedback to up shift. I also tend to downshift more because I love the sound. Net/net my driving has changed to where I'm doing the things that will hurt mileage without being aware. My case...and your mileage my vary!

fbbob96 Posted June 1, 2012 Report Share Posted June 1, 2012 I got 23.6 mpg on a back road rural trip,it was about a 3 hour trip, going just about the speed limit....50-65. Around town about 15 -17. Link to comment Share on other sites More sharing options...

1972mach1 Posted June 9, 2012 Report Share Posted June 9, 2012 Highway I get 9L/100km = 26 MPG. Worst City I get 18L/100km = 13 MPG. Average is 14L/100km = 16 MPG. Link to comment Share on other sites More sharing options...
backafter20 Posted June 9, 2012 Report Share Posted June 9, 2012 Woo Hoo! I finally get to out-perform the GT-500 with my n/a Shelby GT! I do all city driving and get 22mpg, taking every opportunity to rev the engine and accelerate unnecessarily in traffic, with no thought to being economical. I have no idea what I'd get on a long highway trip, but it'd have to be in the high 20's. I still have serious supercharger-envy, though. I'd happily give up some mpgs to run with the big guys.

Criminal Pilot Posted August 26, 2014 Report Share Posted August 26, 2014 Here's a link to the mileage history of my beautiful Kona Blue 2012 GT500 SVTPP! https://www.fuelly.com/car/ford/mustang/2012/CriminalPilot/249412 As you can see, she has her good days and her bad days. Depends primarily on how much I press the gas pedal that day! My best is 8.5L/100KM which is about 27MPG US (that was all highway), and my average as you can see is right on the nose of 15MPG. I drive relatively aggressively, accelerating from red lights up to the speed limit quickly, aggressive through wide open corners, etc. Low-gear, high RPM.. I like to listen to her purr loud enough to drown out the sound of my wallet crying away in my back pocket. I didn't buy it to be concerned about mileage. But I still love to make fun of my friends with "normal" cars like civics and other SUVs because my 550HP monster still gets almost 30MPG highway! Hope my data helps somewhat! I'm at about 23,000km now (just over 14,000 miles). Mileage has maybe improved marginally since new. Not enough for me or my wallet to notice, but maybe the statistics logged will reflect the improvement. Link to comment Share on other sites More sharing options...
Bill Hamilton Posted August 26, 2014 Report Share Posted August 26, 2014 I use the Fuelly website also and have tracked my last 2011 GT-500 for 22,000+ miles and my present 2014 for over 8,000 miles. I've found the in car mpg computer is usually off a bit. It normally shows slightly more fuel used than the actual pump number. You can go there and look at other cars to see their range of fuel mileages. I'm also amazed at the mpg I've gotten with both cars. Link to comment Share on other sites More sharing options...
Secondo Posted August 26, 2014 Report Share Posted August 26, 2014 +1 I'm amazed that my supercar gets 18mpg average and a best of 25mpg on a highway trip. Link to comment Share on other sites More sharing options...
David Hawkins Posted August 26, 2014 Report Share Posted August 26, 2014 If you don't reset your mileage calculator in your Drivers Information Center (DIC) it will show you the average mileage over the life of the car. So if you started with 2mpg it will take a long time to get it up past 12mpg. Phill SO......is the DIC pretty accurate? Some people say it's not, especially when I tell them the MPG's I'm getting. Going up to Charlotte for the 50th, on Interstate, averaging 80MPH most of the way up, I was getting 37-39 MPG (2012 V6, 6 Spd. Auto). I would reset the DIC often to make sure. I still reset it almost daily and I have been getting 24 to 28 around Town and I am not a slow driver. I am usually the first one out the gate when the light turns green and up to speed in just a couple of seconds. Link to comment Share on other sites More sharing options...

I am usually the first one out the gate when the light turns green and up to speed in just a couple of seconds. In my two Shelby's (2011 and 2014) I've found the onboard computer to be 5% to 8% off. I reset mine every time plus chart it online. The DIC may say I used 9.2 gallons but the pump only shows 8.8 or so. Also I don't continue to pump fuel in after it cuts off. In the old days you could put another half gallon or so in the filler neck. The owners manual and other sources say to stop as soon as the automatic cut-off stops fueling and I do.

rocky Posted August 27, 2014 Report Share Posted August 27, 2014 With mods I can get 21 to 23 mpg on the highway if I use cruise control, if I am around town it goes down to about 14 or 15. But if I get the blower kicking in I get about 0. Link to comment Share on other sites More sharing options...
SHLBY EH Posted September 6, 2014 Report Share Posted September 6, 2014 The owners manual and other sources say to stop as soon as the automatic cut-off stops fueling and I do. Bill, why is that?

David Hawkins Posted September 6, 2014 Report Share Posted September 6, 2014 Bill, why is that? Any idea? Old habits die hard and I still try to squeeze in a few more drops after the cut-off. It's because of how the Venting is set up. If you fill it past the Click Off, you will smell Gas inside the Car. Link to comment Share on other sites More sharing options...

Yeap, Ray. As said by tesgt50 plus I believe it has something to do with emissions also and keeping vapors down. Link to comment Share on other sites More sharing options...
mavisky Posted September 9, 2014 Report Share Posted September 9, 2014 That seems low. Even here in Atlanta where it takes me 45 minutes or so to cover 16 miles on the way to work and back on a mix of city street on the way into work and about 50/50 side streets and interstate on the way home I average in the low 16's with the A/C on and the top down. Prolong drives on the interstate at 80mph show about 22-23 with the factory 3.31 rear gears. Link to comment Share on other sites More sharing options...
