The IROC-Z model of the Chevrolet Camaro first made its public appearance in 1985 as an add on option to the 1985 Camaro Z28 model. But its origin began long before that. IROC stands for International Race of Champions which is an automobile racing series similar to what NASCAR is.
The car shared its platform and major components with the Pontiac Firebird, also introduced for 1967. Four distinct generations of the Camaro were developed before production ended in 2002. The nameplate was revived on a concept car that evolved into the fifth-generation Camaro; production started on March 16, 2009.n addition, the Camaro was designed to fit a variety of power plants in the engine bay. The first-generation Camaro lasted until the 1969 model year and eventually inspired the design of the new retro fifth-generation Camaro.
