The second-generation debut for the 1970 model year was delayed until February 26, 1970, because of tooling and engineering problems; thus, its popular designation as a 1970½ model, while leftover 1969s were listed in early Pontiac literature without a model-year identification. This generation of Firebirds was available in coupe form only; convertibles disappeared until 1991 after the 1969 model year.

Replacing the “Coke bottle” styling was a more “swoopy” body style, while still retaining some traditional elements. The top of the rear window line going almost straight down to the lip of the trunk lid, a look that was to epitomizes F-body styling for the longest period during the Firebird’s lifetime. The new design was initially characterized with a large C-pillar, until 1975 when the rear window was enlarged.
