All three national series follow an elimination-style postseason format. Each round is made up of three races, with the final race of each round acting as a playoff elimination race, where a number of drivers (four in most cases) are eliminated from the postseason. This culminates with the Championship 4 title race, where the highest-finishing playoff driver among the Championship 4 in each series is crowned the champion. This year’s Championship Weekend is Oct. 31-Nov. 2 at Phoenix Raceway.
Sixteen drivers qualify for the NASCAR Cup Series postseason, 12 for the Xfinity Series and 10 for the Craftsman Truck Series.
The simplest way to qualify for the NASCAR Playoffs is to win a race, which clinches a postseason spot. At the end of the regular season when the field is set, series winners advance into the postseason. Any remaining positions are filled based on regular-season points.
