The Top 10 Moments of the 2025 NASCAR Cup Series Season

The 2025 NASCAR Cup Series delivered a thrilling mix of dominance, heartbreak, international expansion, and playoff chaos, culminating in Kyle Larson’s second career championship. Larson overcame a challenging season to edge out Denny Hamlin in a dramatic Phoenix finale, becoming the 18th multi-time champion while denying Hamlin his elusive first title.

With road-course mastery from Shane van Gisbergen, repeat Daytona glory for William Byron, and record-setting finishes, here are the top 10 most unforgettable moments of the year.

1. Kyle Larson’s Dramatic Championship Win at Phoenix
In a heart-stopping finale, Larson claimed his second Cup title without leading a single lap in the race. A late caution caused by William Byron’s flat tire flipped the script, allowing Larson’s two-tire strategy to propel him to third behind race winner Ryan Blaney—enough to seal the championship over a devastated Denny Hamlin, who had dominated until the final laps.
