2015 to 2017 Mustang GT — Performance Parts, Specs and More

By the time the 2015 Mustang GT was released, the Coyote 5.0L engine had made the Ford Mustang one of the most popular — and FASTEST — cars on the road. Then, the 2015 model year brought a brand new retro-meets-euro design: the S550.

While the Mustang already had one of the top-performing powerplant setups on the market, the sixth-generation S550 body and chassis provided a more ergonomic shape. Additionally, every model now came with independent rear suspension (IRS), along with improved steering and handling, which made a big impact on the track and racing prospects for the 2015 Mustang GT.

Quality Suspension Makes A Difference

The S550's IRS initially made some people wary of the 2015 Mustang GT's straight-line performance. However, leaders in aftermarket suspension products, like BMR Suspension and UPR Products, quickly began dominating both the street and strip. They set records for 60-foot times and 1/4 mile times, proving the difference that high-quality suspension and other performance parts can make to an already-strong platform.

What Makes The Coyote Engine So Special?

We're tempted to say, "Dumb question, moving on." But, in an effort to be a little less arrogant, we'll explain. Introduced on the 2011 Mustang GT, the Coyote engine has stuck around for a reason. It. Is. A. Beast. It's powerful, loud and shockingly efficient. In 2015, the Coyote got a good horsepower bump, and it stuck around on the 2016 and 2017 Mustang GT. Hell, it's still in the 2020 models! Some maniacs (our favorite kind) have even taken to "Coyote Swapping," putting Coyotes in old Fox Body and New Edge Mustangs. It's just a damn fine engine. That said, part of what we love about it is how easily modified it is — a few engine upgrades can really unleash the beast.
