12. 1985 Holden Commodore HDK VK SS Group A
The 1980s marked the absence of proper muscle cars in America, but in Australia, the trend lived on in a different form. Those cool-looking coupes were gone, so car manufacturers turned to performance versions of regular sedans. The muscle cars they produced in this period were all homologation models for Australian racing championships. The 1985 Holden Commodore SS Group A was the perfect example of such a car.
Holden built the SS Group A to comply with a new set of FIA rules. This made it eligible to race in Europe, as well. Under the hood was a high-performance version of the 5.0-liter V8. It delivered 260 HP, which was a high number if you consider that the 1985 Corvette had only 245 HP on tap.
