The latest reliable details show that the 2025 Supercars Championship introduced a Finals Series with an elimination-style format, plus expanded calendar and new event formats, culminating in a season finale at Adelaide where the champion was decided after a multi-race weekend. The changes were announced in October 2024 and implemented for the 2025 season.[3][5][7]
Key points
- Finals Series: The championship used a two- or three-stage knockout style culminating in Adelaide, with automatic qualification for the top point-scorers plus Sprint and Enduro Cup winners.[2][3]
- Calendar expansion: The 2025 schedule expanded to 13 rounds, adding a new Perth street race and reconfiguring Sandown and other venues; Sandown remained a pivotal final weekend venue.[1][6]
- Event formats: The Finals featured high-stakes formats at Gold Coast, Sandown, and Adelaide, with point resets and elimination rounds to determine the champion.[2][3]
Illustrative example
- Adelaide hosted the final round in which the champion was crowned from the remaining contenders after eliminations across the preceding rounds, consistent with the new Finals structure.[5][7]
