44. Chevrolet Camaro IROC
The third-generation Camaro was a well-received and popular car. Still, after a while, buyers wanted more power. So Chevrolet delivered it in the form of the legendary IROC-Z version. Introduced in 1985, the IROC-Z was a tribute model to the Chevrolet-sponsored International Race of Champions (IROC) racing series (via Motor Trend).
Under the hood was a 350 V8 with 225 HP in early versions and 245 HP in later versions. Buyers could opt for manual or automatic, and the suspension was tuned as well as steering. Chevrolet even offered a cool-looking convertible, the first Camaro ragtop in 18 years.
