10. 1977 Holden Torana A9X
After the muscle car boom in the Australian market, the conservative part of the government put a ban on the production of high-performance cars. They called this ban the “Supercar Scare.” It was a publicly announced action following several dangerous incidents involving fast driving in urban areas. It prompted many car manufacturers to stop producing muscle cars for the public. They started to concentrate on the safer, regular models.
However; in 1977, Holden produced a high-powered version of the compact two-door Torana they called the A9X. It featured a 5.0-liter V8 engine and a host of other upgrades and performance components. The car was also a homologation special for participating in the famous Bathurst race. Although the Torana A9X lost the 1977 Bathurst, it reignited the muscle car battle with Ford.
