2021 Mustang Mach 1 revealed as limited-edition model
The first-generation Ford Mustang had many variations after it debuted more than half a decade ago. One of the iterations was the fastback coupe that debuted in the late-1960s, and available in hopped-up Mach 1 form. The latter now returns as a trim level for the current Mustang, with a naturally aspirated 5.0-litre V8.
