I've had my '15 GT for almost two weeks now and I am getting 24.4 mpg. It's about 70% highway/30% local roads. And I do step on it when I get the itch to! My '14 V6 got 23-24mpg mpg with similar driving style.....I couldn't be happier!
A recent Cars.com report found that during a 200 mile drive on the highway, the EcoBoost Mustang posted highway fuel economy numbers in the mid-30s mpg range while driving at 60-70 mph highway speeds. Add in heavy bumper-to-bumper traffic during a busy holiday weekend, and the turbocharged four-banger averaged 27.2 mpg and 27.6 mpg during a 70-mile ride from Chicago, Illinois to Michigan City, Indiana, and back.
I found this to also be true on my trip from Atlanta to Ann Arbor and back I averaged 32.5 miles per gallon. And that included some time in construction traffic where it was stop and go. To give a reference, with my 2007 and 2010 Mustang V6's, I would have to work hard to make it to Georgetown, KY from Ann Arbor before I had to fill up. With my 2012 Focus, it was London, KY. With my 2015 Mustang Ecoboost, I made it to Williamsburg, KY and could have reach Caryville, TN with no problems. I filled up in Williamsburg just to be safe since there are not a lot of gas stations once you get into Tennessee on I-75.
My problem is I can not keep my foot out of it! I love to hear that Turbo spool up and the sound of my flowmaster exhaust. Which really improved the sound of the Ecoboost. I do not regret not getting a GT at all.
I have no regrets either, the fuel economy is just a plus to me. I only drive 8 miles to work each day, no hwy but the speed limit is 55 then drops to 50. I have been going two weeks before filling up on a 1/4 tank. And with the Bama tune, man this thing is quick!
Here is my Trip screen from yesterday. I filled up because I was about to hit a construction backup, but based on the fill up and what was left in my tank, I could have reached 500 miles if I could have continued without the delay.
