After a 17-year dormancy, the Mustang Mach 1 returns for the 2021 model year with a whopping 480 horsepower from its 5.0L V8, as well as a mind for the track. Tweaked parts from the GT500 and GT350 get bequeathed to the Mach 1, making it the most track-focused in the ‘Stang stable. The Mach 1 gets special aerodynamics to increase downforce by 22% over the Mustang GT and by 150% with the optional Handling Package, making it more adherent to the tarmac. The Mach 1 also gets the Mustang’s first rev-matching system for either the Tremec 3160 6-speed manual transmission (with the iconic white cueball shifter) from Ford Performance or the 10-speed automatic. Staggered rubber (9.5-inch front, 10-inch rear) on 19-inch wheels, combined with the unique spoiler, twin hood scoops, and special graphics help set the Mach 1 apart. All fender badges, mirror caps, and the Mustang emblem in the grille all get a low-gloss Magnetic Gray treatment for even more distinctiveness The interior also gets gussied up with a Dark Spindrift 12.3-inch digital instrument cluster, a large as well as special badging denoting its chassis number. The Mach 1 will go on sale in the spring of 2021.
