26. HSV GTS 300
The late ’90s brought a rise in power levels, as well as new technologies and materials. The result was a bump in performance and a new lease on life for Australian and American muscle cars. But 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 in the Australian muscle car scene.
First, there was the engine, a Callaway-produced LS1 5.7-liter V8 with 400 HP. Packed in a sedan body with beefed-up suspension and brakes, the GTS 300 could accelerate from 0 to 60 mph in just 5.1 seconds. All that made it one of the fastest sedans in the world.
