Well the secret is out! We now have a 2015 Mustang GT in our possession and the second it rolled into our parking lot we started tearing into it! The new S550 Mustang platform brings plenty of new and big changes. Most of these big changes have all been rumors and secrets held closely by Ford.
Our Triple Yellow 2015 Mustang will be a test mule for all the latest performance parts for the new S550 platform. In order to do this properly we have to get solid baseline; therefore, the second it rolled off the trailer we took it straight to the dyno!
The 2015 Mustang GT features a newly redesigned 5.0L V8 Coyote engine. That features a host of engine improvements over the previous generation. These include improved cylinder heads, camshafts, intake manifold and other modifications. These performance improvements netted us a solid 375 horsepower on the dyno. With most factory 2011-14 Mustangs dynoing around 350-360 horsepower, this was roughly a 5-10% improvement in horsepower over out-going S197 Mustang models.
Our 2015 Mustang GT Premium is pretty much fully loaded. Below is a list of factory-installed options so you can get a better idea of exactly what was on the dyno.
