The Ford Mustang Bullitt is set to sunset after the ’20 model year, and its replacement—the Mustang Mach 1—is supposedly set to arrive for 2021, which makes this prototype perplexing.

The prototype in question is wearing camouflage front and rear. It also appears to be wearing the Dark Highland Green exterior paint that is a signature of the current Bullitt. Given the presence of the camouflage, it would appear that the vehicle will wear some unique fascias front and back. The front end, in particular,plate backing pad looks to be slightly different than what’s currently available on the Mustang line. Meanwhile, the bright multi-spoke wheels appear more in line with what we’d see on the Mustang Pony Package. That said, the bright window trim seems to be right in line with what the Bullitt currently offers.

Little is currently known about the Mustang Mach 1, other than the fact that it will launch for the ’21 model year. It will allegedly have some performance enhancements over the traditional Mustang GT on which it will be based.
