It’s not unusual for automakers to make mild adjustments to their cars from model year to model year. It’s a little less common, though, for them to announce changes before the car has even left the factory, as Ford has done with the Mustang Mach 1.

Returning to the Mustang lineup for the first time in 17 years, the new Mach 1 was launched in June 2020. Since then, though, Ford’s designers have been tinkering with some of the car’s finer details.

The updates are subtle, but the handy infographic below gives you all the information you need to pick apart the differences. The first, and perhaps easiest to notice, is the slight change to the “Mach 1” badge. Although the shape hasn’t changed at all, Ford’s design team has added a silver border to make it read better on darker cars.

The next change is a little subtler but still has a meaningful impact. To make the front end look a little meaner, the team changed the lower grille color from Magnetic Gray to low-gloss black. It’s the bay leaf of design changes in that you probably won’t notice the change of color on the street, but the overall improvement will be appreciated.

Finally, Ford changed the shape of the fender striping and says that this tweak was made largely to improve quality and production processes.

And that’s it. Like any artist at an easel, Ford’s designers have been tweaking and fettling to make sure that everything is just right when the Mach 1 hits the streets.

“With any program, you want everything to be perfect but when you’re bringing back a classic like Mach 1 it is imperative,” said Anthony Colard, senior advanced designer. “This team just kept pushing and pushing for perfection.”

What won’t change, though, is what’s under the hood. Powered by a 480 hp version of the 5.0-liter Coyote V8, the Mach 1 will be offered with a six-speed manual transmission as well as a whole host of handling modifications that, according to Ford, should make it nearly as quick around short tracks as the GT350.

The very first Mach 1 is set to sell at Barrett-Jackson’s Scottsdale auction in March.
