A restyled Firebird (and similar Chevy Camaro) went on sale in spring 1990 as an early 1991 model. The new rear-drive Firebird was mechanically unchanged, but sported new front and rear fascias, smaller retractable headlamps, and a restyled rear spoiler. Firebird was available in both 2-door hatchback and convertible form with four engines. They included a 140-horsepower 3.1-liter V6, a 170-horsepower 5.0-liter V8, a 200-horsepower 5.0-liter V8, and a 235-horsepower 5.7-liter V8. The 5.7 V8 came only with an automatic transmission, while the other engines offered both an automatic and a 5-speed manual gearbox. A driver-side airbag was standard on all Firebirds, but antilock brakes were not offered.
