37 Cars On Entry List In Final Race of Cup Series Playoffs Round of 8

Six drivers are set to battle it out for the final two spots available in the 2025 NASCAR Cup Series Championship 4 in Sunday's Xfinity 500 at Martinsville Speedway.

While Chase Briscoe, who won last weekend at Talladega Superspeedway, and Denny Hamlin, who won two weeks ago at Las Vegas Motor Speedway, know they are going to battle for the title in Phoenix, Kyle Larson, Christopher Bell, William Byron, Joey Logano, Ryan Blaney, and Chase Elliott will have one last chance to secure their place to fight for the Bill France Cup.

Heading into the race, Bell sits 37 points above the Playoff cutline, while Larson is 36 points to the good. However, a win by any of the other four drivers below the cutline would result in the elimination of either Bell or Larson. So, it'll be anxiety for both drivers throughout the entirety of the race.

As those six drivers attempt to lock into the Championship 4, they will have to navigate through a field of 37 cars in Sunday's 500-lap race around the 0.526-mile paperclip.

The lone unexpected entry on the entry list this week is Casey Mears, who will reprise his role as the driver of the No. 66 Garage 66 Ford Mustang Dark Horse, which will carry sponsorship from SI Yachts.

Mears, who will notch his fourth start of the season, is attempting to get his career starts total to 500 in NASCAR Cup Series competition. With a start at Martinsville on Sunday, the 2007 Coca-Cola 600 race winner, will be just seven starts shy of the milestone.

Here is the complete entry list for the 2025 NASCAR Cup Series Xfinity 500 at Martinsville Speedway (Race 35 of 36):
