2015 Ford Mustang S550 platform name confirmed

The platform name for the 2015 Mustang has been confirmed to be the “S550“. This will be the sixth platform in the Mustang’s nearly 50 year history.

This is the first new platform since the S197, which began way back in 2005. Signifiacant updates to the S197 Mustang came in 2010, 2011 and 2013, but the changes were not substantive enough to warrant a platform designation change.

What to expect from the 2015 Mustang (S550)?


Ecoboost turbo 4-cylinder
5.0L V8 (spied here)
V6 (remains to be seen)
Independent rear suspension (spied here)
S550 Mustang to be smaller and lighter than current platform


Styling expected to be more modern and less retro, possibly taking cues from the Ford Evos Concept.
