I was very close to purchasing a 2013 GT500 as a DD until I saw this. I cancelled the order for a number of other reasons and went with a 2014 Cali Special instead. This is one of the main reasons why I cancelled the order. I understand that the MPG is a trade-off for the power of the GT500, but seriously... 9.5 MPG?? Note how this fuel gauge is at 3/4 and there is only 114 miles to empty with 1155 miles on the odometer. This makes me feel better about my decision to go with a GT. Sure, I don't have the power and presence of a GT500, but my average MPG is 20-22 with M6 and 3:55 gears. I also understand that the computer can be a little inaccurate...what are you guys getting out there with your average MPG?

The car is not moving. It's just idling there. What is the mpg at cruising speeds? I believe those numbers change depending on driving conditions. But whatever makes you feel better about buying much less of a car. :\

I averaged between 16-18MPG. (before winter storage) It's all in how hard your drive it. Those horses like to be fed. 9.5mpg? The exhaust sounds great but it is important to shift once in a while.

BTW if your buying this type of car your not looking at mileage lol

I am skeptical that 9.5 mpg is based on a normal use. The number depends on the last mileage reset and the use since then i think. it's quite possible the numbers come from heavy throttle use during the last interval. That's my guess. i'm sure the 5.8 gets closer to 16-18 or better during normal use.

Does it show real time mpg or just average?

Shelby Mama

I believe it was just average MPG. There is a way to show a bar graph as to the last 10 minutes of driving for fuel mileage. I grin when I see the bar graph low

Surprised this is the only post stating this. Come on OP, you were going to buy an almost 700 hp car and was shocked to find that it wouldn't get Prius MPG?

Not knocking the GT500 at all, it is a fantastic automobile. I researched it for quite some time before making up my mind and have seen similar gauge images of used GT500's on cars.com. I wish I could own one, but even 16 average MPG for a DD is not acceptable with my commute (65 miles per day) which is why I went with the GT. I guess I threw this out there because even when I drove my new GT off the lot, I didn't see the MPG meter this low. With spirited no-holds-barred driving, I get 16 MPG with the 5.0. I just find it hard to believe that the GT500 gets close to the same MPG.

I was thinking Prius MPG also. You said before I did.

Last I checked, prius average MPG was 48

Shelby Mama

I am happy that your happy with your purchase!

I'm not pulling your leg! I believe the worst mileage I have had with the car is 15.5, and trust me I have red lined it more than a few times. That 6 speed tranny is nice for fuel economy.

I've had a few beers and just messing with you guys. I love mustangs and the GT500, just surprised at this photo is all. Wanted to see what you all were getting MPG-wise.

If you have a 65 mile commute, the GT500 may have got better gas mileage. My 2013 GT500 vs my 2013 GT/Stage 3 Roush vs my 2011 GT Vert, the GT500 gets better gas mileage on the interstate/Hwy. All are highly modded and have been within hours of purchase, so no idea how a stock car does.

Manually calculating my MPG I get 15.8 average (shows 13.5 on dash-never reset), that's modded with plenty of WoT or spirited driving. Interstate/Hwy driving I get 22-24 MPG in the Shelby, even with my mods.

I burn 1/2 tank after 3 trips down the drag strip. Figure 1/2 tank through the traps and back 3times= 1-1/2 miles per 6 or so gallons. Someone figure out the math for me.

I've taken a 120 mile trip with several stints at over 100mph and lots of passing and still gotten 19mpg so I'm happy.

The 11 thru 14 GT500's don't pay the gas guzzler tax, that should be a hint !!
.
My 2011, before I started modding it, with less than 1500 miles, got 24.2.mpg
( 3.55 gears ).................the 13/14's have 3.31's
Driving habits determine your mpg....................I think you made a poor choice.

R3troGT

The 2010 Shelby did not have a guzzler tax either.

+1...OP, if you're concerned about DD gas mileage, then you should pick a car that meets your requirements...if it's the CS and your satisfied with it, congrats!

If you have the means to drive this car as a DD, then hats off to you. I don't think I made a bad decision actually. I bought a mustang because I love them. There is no other car out there that I actually like. I bought a GT because of the better MPG/power you get for it. Even if the above photo is inaccurate, a GT will always get better MPG than a Shelby. I want to have my cake and eat it too. I also said there were other reasons why I didn't buy a Shelby. The price. I'd rather have a $300/month car payment than a $700 one. The insurance is more money in NJ (one of the highest insurance rates in the country). Also if I owned a Shelby and drove it to and from work I would always worry about the weather, bad drivers, flying rocks, bird poop, shopping carts, etc, etc. Those things are a little easier to accept when the car is half the price. I envy you guys a little for having the means to drive this fantastic car, but I am not unhappy in my decision. I can drive a mustang to work every day and that's just awesome.

I have installed long tube headers along with a racing tune and pulley swap on my '13, and the worst mileage I get (average) is roughly around 16mpg. Highway driving is up toward 20mpg if I'm not playing.

Of course a GT will always get better MPG than a Shelby; that's why one's a GT and one's a Shelby. As far as price, do your homework and find a car that isn't marked up. Put money aside when you don't have to spend it. I pay less than $300/month for mine. Talk about having your cake and eating it too...
