14. 2000 HSV GTS 300
The late 1990s brought a rise in power levels, and new technologies and materials. This created a bump in performance and a new lease in life for Australian and American muscle cars. One of the best Aussie performance machines from that period was the HSV GTS 300. Despite being limited to only 100 copies, the HSV GTS 300 was a big milestone for the Australian muscle car scene.
The engine was a Callaway with an LS1 5.7-liter V8 producing 400 HP. They packed this engine in a sedan body with a beefed-up suspension and brakes. The GTS 300 could accelerate from 0 to 60 mph in just 5.1 seconds, making it one of the fastest sedans in the world.
