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.
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.
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.
The specs for the first S550 GT were impressive. That's even before adding any 2015 Mustang GT performance parts.
You’re not going to see a huge difference from 2015 to 2016, although the 0-60 time did go down slightly. Some 2016 Mustang GT performance parts could take it down even lower, though.
Again, no major differences for the 2017 Mustang GT specs, but they're still likely to impress.
We've already sung the praises of the S550 design, but you can push the look of your 2015-2017 Mustang GT beyond badass with body and styling products from companies like Roush, Cervinis, TruFiber and more. Are you a fan of the carbon fiber look? You'll find a vast assortment of carbon fiber parts available from Anderson Composites, Icon and TruCarbon.
