The Ford Mustang adds a new trim level to the popular lineup in 2021. This year you can now get the Mach 1 trim level, a special edition that brings more power than before and adds some luxuries such as a bigger 12.3-inch infotainment screen. More safety technology is also included on the Ford Mustang, which now gets Ford's CoPilot360 safety amenities as its standard safety tools on any trim level. With the Mach 1, you have six trims to choose from in the Mustang.
