The Hankook Australian Drivers' Championship represents the premier tier of open-wheel competition in Australia, centered on the historic Gold Star title. Established in 1957, the championship has a long-standing legacy of identifying the fastest drivers in the region, with a roll of honor that includes local legends and international stars. The Australian Drivers' Championship has been contested since 1957 — the third oldest title in Australian motorsport. In 2024, stewardship passed to AASA, and the X1 was selected as the car to contest the prestigious title — bringing premier open-wheeler performance to the serious competitor for the first time. Today the ADC fields 20-plus cars each round. Professional and amateur alike. One car. One champion.
