A prototype for what could be an S550-based Ford Mustang Mach 1 has been spotted running around Michigan. Our spy photographer managed to get several shots of the car, and a video posted to YouTube by Mustang6G has clear audio of the exhaust note.
The changes that will really draw the eye, of course, are the aerodynamic ones. Ford added a big front splitter that looks like it might be adjustable as well as a larger spoiler on the rear deck. That rear diffuser has been hacked away to fit the quad exhaust, so expect a new piece to sit in its place on the production car. Aside from those parts and a couple of red hash marks on the left front fender, this particular prototype looks just like a normal Mustang GT coupe. The stylistic changes we’d expect on a Mach 1 – a shaker hood, perhaps? – are conspicuous by their absence.
Really, all that is missing from this Ford Mustang to make it a lock for the new Mach 1 is a Shaker-style hood scoop, but with the Chrysler Group offering the Shaker as a trimline for the Challenger, Ford might need to come up with a more trademark-friendly hood design for the new Mach 1.
Although Ford has indicated that it will offer special editions of the current-generation Mustang, it is possible that the automaker could be using the mule to test mid-cycle performance upgrades for the Mustang GT to compete with the more powerful and lighter Chevrolet Camaro SS/1LE.
