The 2016 Mustang receives a few new optional packages for the second model year of the S550 generation Mustang. One of those that has yet to be seen until now is the new Interior and Wheel Package (601) available for both the 2016 Mustang GT and EcoBoost models.
This new package adds 19″ x 8.5″ low gloss black painted machined-aluminum wheels, embroidered pony logo outline on the seat back, and premium carpeted floor mats with embroidered pony logo.
