We finally caught the first glimpse of the 2018 Mustang prototype last month and in the few weeks since then Ford has been actively testing the S550 mid-cycle refresh all over Michigan.
These latest photos come courtesy of the quick hands at Ford Authority who spotted this 2018 Mustang prototype rolling through the town of Ann Arbor, Michigan.
Unlike the first sighting, this prototype is wearing quad exhaust tips which we’ve seen before in an S550 Mustang mule and lending proof that the prototype is hiding the upcoming Mustang GT or even Mach 1 variant under the fully camouflaged disguise.
Although the front fascia is heavily covered, we also see a hint of a revised lower grille poking out from behind the front cover.
