It all comes down to this. The Season Finale 500 at Phoenix Raceway. 312 laps of door-to-door, wheel-to-wheel action to decide who takes the glory in 2021. Defending champion Chase Elliot will be out to defend his title against championship contenders in front of a crowd up to 42,000. NASCAR Cup Series, Xfinity Series and Camping World Truck Series will all decide their victors at what will be one of the most dramatic race meetings of the year.
