The vaunted Z28 was superseded as the top performance offering by the IROC-Z, which got its name from the specially prepared Camaros used in the International Race of Champions racing series.
In addition to a stiffer suspension and special wheels and tires, the IROC had exclusive use of the L69 190-horsepower carbureted 5.0-liter V-8 that came only with a five-speed manual transmission.
Optional on the IROC was a 215-horsepower Tuned Port Injected 5.0-liter V-8, which came only with a four-speed automatic. The latter was optional on the Z28, which came standard with a 165-horsepower version of the 5.0-liter V-8 that was optional on lesser Camaros.
Other engines included a 135-horsepower 2.8-liter V-6 (standard in the Berlinetta) and the base 2.5-liter four with 88 horsepower.
The Berlinetta's "video game" dash still drew some barbs, but overall, the Camaro -- at least in hotter Z28 or IROC-Z form -- was applauded as a bargain among high-performance sports coupes.
Sales reflected this view: Though lower than the year before, nearly 180,000 units were nothing to sneeze at, even at Chevrolet.
The IROC-Z had 16-inch aluminum wheels
and beefier tires, among other upgrades.
