The first-generation Camaro debuted in September 1966, for the 1967 model year, up to 1969 on a new rear-wheel drive GM F-body platform and was available as a two-door coupé or convertible with 2 2 seating, and a choice of 230 cu in (3.8 L), 250 cu in (4.1 L) inline-6 or 302 cu in (4.9 L), 307 cu in (5.0 L), 327 cu in (5.4 L), 350 cu in (5.7 L), and 396 cu in (6.5 L) V8 powerplants.
Concerned with the runaway success of the Ford Mustang, Chevrolet executives realized that their compact sporty car, the Corvair, would not be able to generate the sales volume of the Mustang due to its rear-engine design, as well as declining sales, partly due to the negative publicity from Ralph Nader's book, Unsafe at Any Speed.
The first-generation Camaro lasted until the 1969 model year and eventually inspired the design of the new retro fifth-generation Camaro.
The first-generation offered a standard, Super Sport, and Rally Sport editions.
It went on sale on September 29, 1966, for the 1967 model year and was designed as a competing model to the Ford Mustang.
