The S550 Mustang features large upper and lower grille openings for maximum cooling capabilities. The interior completely changed in 2015-17, Ford used real world materials to build the bulk of the interior – aluminum, leather and stitching. Ford also debuted a whole new engine to its line up, while keeping to the heritage of the 5.0L V8 and 3.7L V6, the 4-cylinder 2.3L turbo made a comeback. Ford ditched the live axle and joined the modern world with an aluminum IRS for improved handling and strength!
