2003 Ford Mustang

In 2003, the Mach 1 returned with a bang. It can be noticed anywhere with the return of the shaker hood scoop, while underneath the ram air scoop channels fresh air to the intake, increasing power and torque for the Mach 1. Just above the rocker moldings runs a low gloss black stripe also identifying the Mach 1. The interior features increased lateral support and comfort weave black leather seating, also reminiscent of past Mach 1s. Standard is the Mach 460 six-disc in-dash CD changer audio system.
Under the hood is a 4.6L, 32 valve dual-overhead-cam V-8, which exceeds more than 300 horsepower.

The Mach 1 is lowered a half of an inch and has firmer suspension, creating smoother handling. Also as a reminder of the Mach 1's heritage, 17-inch Magnum 500s are standard.

Added to the color options are Dark Shadow Grey and Redfire. Mineral Grey and Laser Tint Red were deleted from the color options list. Azure Blue was also added, but was only available for the Mach 1.

In June of 2002, 2003 Cobras were available with a supercharged 4.6L DOHC V-8 with 390 horsepower. Heat from the engine was discarded through two inverted hood scoops. Both bumpers were redesigned on the Cobra, and GT side scoops as well as a new spoiler were added.
