1989 Camaro

1989 signified the return of the RS designation (last used in 1980). The Rally Sport was now the base model featuring body ground effects mimicking the IROC and the previous Z28. They had the 2.8 V6 fuel injected motor as standard with the 5.0 305 TBI as an option. The raised rear spoiler that became available in 1988 on the base coupes was short-lived and done away with for this year. The IROC-Zs were still available with the 170 hp (127 kW) TBI 305, 215 hp (160 kW) TPI 305, or the 235 hp (175 kW) TPI 350. IROCs had a new dual-converter option that boosted hp to 240 that was available only with the TPI 350 (and mandatory 700-R4 automatic). Also during this year all camaros were outfitted with the vats/passkey security system.
