Chevrolet Camaro IROC-Z
The third-generation Camaro was famous. But after a while, the buyers wanted more performance and power. So Chevrolet delivered that in the legendary IROC-Z version in 1985. The IROC-Z was a tribute to the Chevrolet-sponsored International Race of Champions racing series (via Car Gurus).

However, it was more than an appearance package and a cool name. Under the hood was a 350 V8 with 225 HP and in later versions, 245 HP. Buyers could opt for manual or automatic and tuned suspensions and steering. Chevrolet even offered a cool-looking convertible: the first Camaro ragtop in 18 years. The IROC-Z proved to be a popular and influential muscle car that finally brought some actual performance to buyers.
