Radical Cup Australia is a national racing series featuring purpose-built sports prototype machinery. Sanctioned by Motorsport Australia, the category offers a pathway for drivers transitioning from karting or club racing into professional GT and endurance competitions. The series often shares the bill with major national championships like the Shannons SpeedSeries. The competition is defined by its use of the Radical SR3, a car renowned for its high power-to-weight ratio and significant aerodynamic downforce. Because the series operates as a one-make championship, all competitors use identical equipment, placing a heavy emphasis on setup knowledge and driver ability rather than budget-driven technical advantages. This parity creates tight, action-packed racing throughout the field, from the front-running professionals to the dedicated privateers in the Am class. Now entering a new era with naming rights partner First Focus, the series continues to grow its footprint in the Australian motorsport landscape. Beyond the sprint format, the inclusion of endurance rounds requires teams to manage pit stop strategy and driver changes, mimicking the demands of international sports car racing. It remains a vital component of the local racing scene, providing a unique platform for high-performance open-cockpit racing that is rare in the region.
