The rivalry between the Chevrolet Camaro and the Ford Mustang intensified
the early 1980s as muscle cars. After the oil crises of the preceding decade
consumer demand for automobiles with higher fuel efficiency surged.
Chevy decided to lighten the Camaro by 500 pounds as a consequence.
Additionally, the carmaker sweetened the pot by introducing the IROC-Z performance
package in 1985. The 350 cu. in. V8 Corvette option went on sale in 1987.
