Jeff, Kevin, and Sky are back behind the mics one last time this season to break down NASCAR Championship Weekend! The 2025 NASCAR Cup Series season ends with Kyle Larson taking home his second championship — despite not leading a single lap at Phoenix.

It was absolute heartbreak for Denny Hamlin, who led 208 laps, started on the pole, and was just 40 seconds away from clinching his first Cup Series title before disaster struck — a late caution from William Byron’s blown tire flipped the race upside down. Hamlin lost crucial track position on pit road, and Larson capitalized to become only the 18th multi-time Cup Champion and the third driver to win multiple titles for Hendrick Motorsports.

The crew also breaks down:
🔥 The epic Truck Series finale, where Corey Heim went seven-wide in NASCAR overtime from P10 to win the title.
⚡ Jesse Love’s shocking Xfinity Series Championship win.
🛠️ The massive offseason change ahead — the Final Four format is gone, and NASCAR is set to unveil a brand-new playoff system for 2026.

Thank you to all of our listeners, supporters, and everyone in the NASCAR community. Mash The Gas will be back stronger than ever in February 2026 to kick off the new season. Enjoy the holidays — we’ll see you at The Clash
