3. Chevrolet Camaro IROC-Z
The third-generation Camaro was a well-received and popular car but after a while, buyers wanted more performance and power and Chevrolet delivered in form of the legendary IROC-Z version. Introduced in 1985, the IROC-Z was kind of a tribute model to Chevrolet-sponsored International Race of Champions racing series. However, it was much more than just 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 ragtop in 18 years. The IROC-Z proved very popular and influential muscle car which finally brought some real performance to the buyers.
