The 1981 Ford Mustang retained the same look as its fellow third generation Mustangs, but featured fewer engine choices. The 2.8-liter V6 was no longer an option. However, the 3.3-liter V6 was now rated at 91 horsepower.
Some of the aftermarket additions included installing a replica T-top from the late 70's.
