First, let me say that I didn't but my2024 GT Vert Premium for the gas mileage, But I am interested in hearing from the community on their experience with mileage. I started out stock and added a bunch of Steeda suspension parts which I love. Using mostly Normal mode and Sport mode, usually around town and on local freeways, I was averaging about 17.5 mpg always on 93 Sunoco Gas. Along about January of this year, that suddenly dropped to about 15.8 MPG average in all the same conditions. In May, I had a Whipple stage 2 installed along with Kooks long tube headers and Kooks high temp green cats. I did this knowing full well mileage would take a hit, but again, I didn't do any of this to get mileage. After Whipple and header install, I'm now averaging about 13.5 MPG. I don't track it and don't do any hard pulls. Just curious what others are seeing in the GT Premium configurations.

It's sad that we have to start with the first sentence, just because we have to defend ourselves first from the people who we expect to react like "You have a GT and you care about gas mileage? Go drive a Prius".

My average is about 11.7L/100km

16.5 mpg currently. With a manual Coyote you have to keep the revs up so you are always ready to roll :rockon:

Seriously, I can get into the looow 20's on a highway cruise.

I think I am sitting at 10.2 or so. That's it. Have not gone on a long trip or done a lot of highway miles. Lol, maybe it's all the downshifting and rev matching.

I get about 17 mpg (going by the dash counter).
Mixture of around town/highways, Tampa area.
I drive with Sport always on.
On each drive I usually get on it a few times.

Premium, 6 sp, active exhaust.

On my '26 GT vert, 6spd, PP, I average 16-17 around town & as high as 24 on freeways

As I tell my Tesla/Prius friends "the only way this car could be less friendly to the environment is if it ran on dolphin fins" :cwl:

I bought a Mustang GT. I never check MPG. :wink:

Most of my driving is local about the village and surrounding area; mileage can't be much to write about. I have seen 22/23 MPG on the few highway (cruise controlled 60 MPH) trips I've taken recently. Best I've gotten was a hair over 28 MPG right after purchase; during sme extended 60 MPH highway cruising.
