17. Chevrolet Camaro IROC-Z
The third-generation Camaro was a well-received and popular car. But after a while, the buyers wanted more performance and power. So, Chevrolet delivered it in the form of the legendary IROC-Z version. Debuting in 1985, the IROC-Z was a tribute model to the 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 a 350 V8 that produced 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 the steering. Chevrolet even offered a cool-looking convertible, which was the first Camaro ragtop in 18 years.
