1976–1980

The 1979 engine options included 301-V8,305-V8,350-V8,400-V8,403-V8, 3.8L-V6 and an 2.5L-I4. Body options included Firebird Redbird Package, Sunbird Formula Package, and sunroof. Air conditioning was available as was 4 Speed manual transmission or 3 speed automatic transmission.

1980 was the final production year of the H-bodied Sunbird. By this time the wagon body style and the optional V8 engine were discontinued. The year featured an unusually long production run in order to provide sufficient inventory to carry dealers into the 1981 model year, in anticipation of the Sunbird's replacement.

A total 479,967 H-body Sunbirds were produced in five model years.

1982–1988

For 1982, the rear-wheel-drive Sunbird was replaced by a new front-wheel-drive compact called the J2000. Appearing as a sedan, coupe, wagon or hatchback, the J2000 was powered by either a 1.8L or 2.0L four cylinder engine. The J2000 shared GM's internationally used J-Body

, which had a similar appearance. Both engines were replaced by a new SOHC 1.8L four, imported from GM of Brazil. This engine used throttle-body electronic fuel injection, in contrast to the carburetor that was used in the 1982 engines, making 84 hp. A 5-speed manual was newly optional. A convertible called the 2000 Sunbird was also new for 1983.

1984 brought a new front fascia for a smoother, less angular look. Also, the lineup was renamed "2000 Sunbird", a title used only on the convertible the previous year. A new turbocharged four-cylinder was available. Based on the standard 1.8L inline-four that powered other 2000 Sunbirds, it used multi-port fuel injection, for a total output of 150 hp. This engine was popular, and more powerful than many V6 engines in competing brands. 1985 was a carryover year, except for the "2000" prefix being dropped. A GT model arrived in 1986. It featured fender flares, hidden headlamps, and the Turbo engine standard. It was available in sedan, coupe or convertible. The GT sedan is very rare, with less than 5000 sold. The GT convertible is the rarest variant, with fewer than 1,300 sold.
A redesigned gauge cluster and new engines made news for the 1987 model year. The gauge cluster featured different graphics, and featured a 120 mi/h speedometer on Turbo equipped models, where 1984-86 Turbo models had just an 85 mi/h speedometer. The new engines were "punched out" versions of the 1.8L, displacing 2.0L. The base engine still used throttle-body injection, for a new total of 96 hp, and the turbo still used port-injection, for a new total of 165 hp. Also, the convertible could only be ordered in GT trim. The rear fascia was redesigned in 1988, and the 4-speed manual was discontinued.

1988.5–1994

Production under the Sunbird name was continued until 1994. The trim levels on both the sedan and coupe were base, SE and GT. The Sunbird SE coupe, SE sedan and the GT coupe

, that gave the appearance of "raised eyebrows" when the headlights were on. The base model initially had the 1984-87 front fascia with exposed sealed beam headlamps. The engines were both the carryover 2.0L 96 hp I4 and the turbocharged 165 horsepower 2.0L four.

In 1989, the base model received a smoother, more aerodynamic front fascia and the model was renamed "LE". An LE coupe joined the lineup also, with the same features as the LE sedan, but for a slightly lower price. The SE sedan was discontinued. In all models, however, a new dashboard was added. It somewhat resembled that of the Pontiac Grand Prix, redesigned for 1988. The most notable change from the previous dashboard is the placement of the stereo. A redesigned AM/FM stereo unit was placed high in the dash. If a cassette player or compact disc player

 (new for 1989) were ordered, they were relocated at the bottom of the dash. The Safari wagon was dropped.

For 1990, the GT and SE coupes received a smoother front fascia with hidden headlamps. The GT convertible is discontinued, replaced by a turbocharged LE convertible, which also retains the GT suspension and steering. In all models, GM's passive seatbelt system was introduced. The seatbelts were mounted on the doors and would stretch out when latched.

, it produced 140 hp at 5200 rpm, and 185 lbft of torque at 4800 rpm. Although there was less horsepower under the hood, power came much quicker and smoother than the Turbo, with about the same fuel economy. The V6 engine could be ordered in any model, save the new-for 1991 base value model. The SE coupe received the LE coupe front fascia, but the GT's fascia could still be ordered with a sport package exclusive to SE coupes.

The largest change for the '92 model year was a revision of the base engine. The 2.0 L SOHC TBI four was replaced with the 2.0 L SOHC MPFI four resulting in a fuel economy increase and power increase. Power was increased from 96 hp to 110 hp and torque increased from 118 to 124 lbft. An SE sedan was once again available, and the base models were dropped and the convertible moved from LE to SE.
The only change for 1993 was the addition of a glass rear window with defroster on convertibles.

As the Sunbird came to a close, the trims were pared down. The SE sedan, SE convertible and GT coupe were dropped for 1994. The LE sedan, LE coupe and LE convertible (moved from SE to LE), and SE coupe stood pat for one more year. The SE coupe was essentially the '93 GT coupe with a lower price.

All GTs featured semi-concealed headlamps and fender flares and "Turbo GT" badges replacing "Sunbird" badges, except on the turbo delete cars where the "Sunbird" badges were replaced by "Sunbird GT" badges. The sedan was dropped for 1988 and the interior was redesigned for 1989. The convertible was dropped for 1990 and the turbo was gone for 1991.
