1 FAMILY OWNER 36K ORIGINAL MILES V8

A major facelift for 1981 gave the Regal a much more aerodynamic profile, helping make it possible for the car to compete on the NASCAR racing circuit. The sloping hood and nose of the car made it the favorite of several NASCAR teams. Richard Petty drove one to victory in the 1981 Daytona 500, and the car won a majority of the 1981 and 1982 seasons races and won the NASCAR manufacturers title in 1981 and 1982.

V8s for street use were still available, but had shrunk to 265 cu in (4.3 L) (1980 and 1981 only, Pontiac built), and the V6 was rapidly gaining popularity. From 1986 to 1987, the 307 cu in (5.0 L) V8 was available as an option. The 3,791 cc (3.8 L; 231.3 cu in) 2-bbl V6 was standard. The 200-4R overdrive transmission was an option with either engine.

For 1980, the Regal was offered in a special Somerset Limited Edition trim which featured unique tan and dark blue designer exterior paint, wire wheel covers, sport mirrors, and chrome Somerset badging. The interior had tan and blue plush velour upholstery, brushed chrome trim, and additional Somerset badging. A Somerset Limited Edition model was also offered on the restyled 1981 Regal. It had unique dark sandstone and camel exterior paint, sport mirrors, and turbine wheels. The interior plush velour upholstery was camel with dark brown piping.
