Throughout 2021, Ford sold 52,414 Mustangs. That includes all trim levels from the base level car with its four-cylinder EcoBoost engine all the way up to the wild Shelby GT500 with its supercharged Predator V8 motor. Understandably, it does not include the all-electric Mustang Mach-E which is an entirely different model. The Mustang has always been a big sales success for Ford even in the days of the Mustang II. It wasn’t until 1991 that the car saw sales dip below 100,000 units per year. In 2020, Ford sold 61,090 Mustangs which was also an all-time low. That was only the second time in history that sales dropped below 70,000.
