There were two generations of the Phoenix, both based on popular Chevrolet models, and both using the GM X platform designation.

[1] The Phoenix differed from the Ventura in only minor details such as the grille and its square headlights and yellow rear turn signals.

For 1980, the Phoenix was downsized and moved to the front-wheel drive X platform, and was available as a 2-door coupe or a 5-door hatchback.

Available engines were a 2.5 L Iron Duke 4-cylinder, carried over from the previous Phoenix, and a new 2.8 L LE2 V6, both of which were mated to a standard 4-speed manual transmission or optional 3-speed automatic.

As with its sister cars (the Chevrolet Citation, Buick Skylark and Oldsmobile Omega), the Phoenix's image suffered because of poor workmanship,[1] two recalls for 1981,[3] and a dangerous tendency for the car to lock the rear wheels upon emergency braking (1980 models only).
