The 2.3 liter EcoBoost engine found in the 2015 Mustang is one of the most talked-about motors of the past two years, and we finally have some hard numbers attached to it. The official ratings are 310 horsepower and 320 ft-lbs of torque, which is comparable to the Mustang’s V8 engines of just a decade ago. Now we’re getting the first reports on fuel economy, and it ain’t too shabby.
A post over on reddit from u/noname87scr claims to work at a Ford dealer, where a 2015 Mustang EcoBoost just showed up. He posted the above shot of the engine bay, and says that the Ford rep claimed he was getting 31 MPG on the highway. 310 horsepower and 31 MPG? I’m still set on getting a Tesla, but those are the kinds of numbers that make it a good time to be a Mustang fan, especially after hearing this torquey EcoBoost engine gettin’ it on at the track.
Just wait until the aftermarket gets its hands on this engine too. 400 horsepower shouldn’t take much more than an ECO reflash, a bigger exhaust, and a small shot of nitrous. The tiny turbocharger could also do with an upgrade, pushing well into Mustang GT territory. The EcoBoost engine comes at a $1,500 premium to the base V6, but is some $7,000 cheaper than the heavier V8-powered GT model, adding to my argument that the V8 muscle car is on its way out.
Ford still hasn’t revealed the official fuel economy figures, but could Ford land numbers as high as 35 MPG on the highway? If a Ford rep was really managing 31 MPG on the highway, and was driving it with any sort of gusto, 35 MPG wouldn’t be too much of a stretch.
