The 1974 Camaro had one major change to the body: a new, more durable, impact-absorbing aluminum bumper created to meet government safety regulations. The Rally Sport option was cancelled from the package list and the Z28 dropped in horsepower to 245, again due to government regulations.
In 1975, the Camaro Z28 was eliminated but the Rally Sport was brought back for production. At this time the most powerful engine was the 155-horsepower, 350-cubic-inch V8, which was nowhere near the amount of horsepower in the first generation of the Camaro.
Leather was offered as an interior addition in ’75.
Although the only change to the Camaro in 1976 was a newly designed grille, 1977 offered the resurrection of the Z28. Even though the new Z28 only provided 185-horsepower, people loved the new decals, badges and stripes. Sales went out the roof compared to the past years with 218,853 Camaros, all models, sold.
