Chevrolet Camaro IROC-Z
Introduced in 1985, the IROC-Z was kind of a tribute model to the Chevrolet-sponsored International Race of Champions racing series. However, it was more than an appearance package and a cool name. Under the hood was 350 V8 with 225 HP in the early years and 245 HP in later versions. The buyers could opt for manual or automatic, and the suspension was tuned, as well as steering. Chevrolet even offered a cool-looking convertible, which was the first Camaro rag top in 18 years. The IROC-Z proved to be a very popular and influential muscle car, finally giving buyers an actual performance.
