The 2001 Ford Mustang Bullitt, like the movie car, was simply a "S-95 New Edge" Mustang GT with some styling changes on the inside and outside along with a slight increase in power due to a different intake manifold.
The exterior of the Mustang Bullitt featured a brushed fuel door,
blacked-out "coral" around the pony on the front grille section, power
coated red brake calipers with a silver "pony" emblem, more aerodynamic
rear body scoops, BULLITT badge on the left rear of the vehicle, and an
altered C-pillar. The C-pillar on the other 2001 Mustangs followed the
same line on the top and bottom; on the Bullitt, the side of the
C-pillar against the rear quarter window angled back in towards the
bottom, giving them a similar shape to that found on the 1968 Mustang
GT. And in keeping with the exterior cues of the 1968 Bullitt car, the
2001 units offered no fog lights or rear spoiler. The 2001 Bullitt was
offered in three colors: True Blue (723), Black (1,818), and Highland
Green (3041).
