The first-generation Chevrolet Camaro appeared in Chevrolet dealerships in September 1966, for the 1967 model year on a brand-new rear-wheel drive GM F-body platform and was available as a 2-door, 2+2 seat, hardtop (no "B" or center pillar) or convertible with a choice of six-cylinder and V8 power plants. The first-generation Camaro was built through the 1969 model year. The 1st generation Camaro's standard drive train was either a 230 cu in (3.8 L) straight-6 engine rated at 140 hp (104 kW) or a 327 cu in (5.4 L) (307 cu in (5.0 L) later in 1969) V8 engine, with a standard three-speed manual transmission. There were 8 (in 1967), 10 (in 1968), and 12 (in 1969) different engines available in 1967-1969 Camaros. The two-speed "Powerglide" automatic transmission was optional. The three-speed "Turbo Hydra-Matic 350" automatic became available starting in 1969. The larger Turbo 400 three-speed automatic was an option on SS396 cars. A four-speed manual was optional.
