Considered by many to be the
next-worse year in performance history next to the introduction of emissions. In
1975 Catalytic Converters were now federally mandated on every car, totally
killing any semblance of performance seen before. Chevrolet performed what was
arguably a smart move, dropping the Z28 from the lineup, rather than offering
the performance legacy with an anemic excuse for an engine.
The only significant change was the addition of the new wrap-around rear window
to increase visibility, and a new two-tone paint scheme on the returning RS
model (replacing the Z28).
