17. 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. So, Chevrolet delivered that in form of their legendary IROC-Z version. Introduced in 1985, the IROC-Z was a tribute model for 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 the 350 V8 with 225 HP in the early years, and 245 HP in later versions. Buyers could opt for manual or automatic and they tuned the suspension as well as the steering. Chevrolet even offered a cool-looking convertible, which was actually the first Camaro ragtop in 18 years.
