The 2025 NASCAR Cup Series Championship race at Phoenix Raceway marked the conclusion of the sport’s controversial playoff format, which has shaped title battles for over a decade. The event, won by Ryan Blaney, crowned Kyle Larson as the season champion.
Introduced in 2014, the playoff system featured a 16-driver elimination bracket leading to a winner-take-all final race between four contenders. While it created exciting, high-stakes moments and increased late-season viewership, it also sparked criticism for prioritizing short-term performance instead of season-long consistency.
The race exemplified these concerns when Denny Hamlin—who led the series in wins and was dominant throughout the season—lost the championship due to a late caution and a strategic pit decision.
“The outcome reignited long-standing debates about the fairness and integrity of the system.”
