GT350’s Tremec 3160 6-speed manual transmission, which features rev matching for the first time. It also comes equipped with the GT350 oil cooler system and Mustang GT’s twin-disc clutch and short-throw shifter.

A set of new 19 inch x 9.5 inch and 19 inch x 10 inch five-spoke Tarnished Dark-painted aluminum wheels are an updated version of the classic Magnum 500 style wheels.
The Handling Package, exclusively available with the 6-speed manual, also includes a larger, unique higher downforce front splitter, new front wheel lip moldings, and a low-gloss Magnetic swing spoiler with a Gurney flap and rear tire spats from Shelby GT500. To enhance track endurance, Ford added two side heat exchangers – one to cool engine oil, the other transmission oil – as well as a rear axle cooling system and lower diffuser from Shelby GT500.
The all-new Mach 1’s grille hearkens back to the original with a deep 3-D mesh, shark-nosed section, and faux lamp elements, but it’s functional, too. The two-piece upper grille, lower grille and valance, and new side grilles, are all designed to aid aero and cooling performance. Low-gloss magnetic and black accents adorn the exterior, including the grille pony badge, mirror caps, and rear spoiler.
Satin Black side and hood stripes are included with reflective accent stripes in any of three colors: Red, White and Orange on the Appearance Package only. Exterior color options include the Mach 1 exclusive Fighter Jet Gray (Appearance Package only), as well as Iconic Silver, Shadow Black, Oxford White, Velocity Blue, Twister Orange, Race Red, and Grabber Yellow.
In addition to the new front splitter and rear wing, a larger underbelly pan, underwing, and belly pan work in unison to keep the new Mach 1 glued to the road. In fact, the Mach 1 generates 22 percent more downforce than a Performance Pack 1 Mustang GT, and the downforce improvement jumps to approximately 150 percent with the Handling Package.
The interior features a unique Dark Spindrift instrument panel with aluminum accents. Other adornments include Ebony seats with an accent stripe, new door sill plates, an updated splash screen on the 12.3-inch all-LCD instrument cluster, a white cue ball shift knob, and engraved badging that displays the vehicle’s unique chassis number.
