NASCAR has announced new details surrounding the format for the 2025 NASCAR All-Star Race at North Wilkesboro Speedway.

The format will again feature two heat races to set the All-Star Race starting lineup and a 100-lap All-Star Open race, plus a 250-lap main event.

In addition to a longer main event, other new aspects include a Manufacturer Showdown, a Promoter's Caution, and modifications to Open qualifying and Pit Crew Challenge eligibility.

The Manufacturer Showdown will feature all manufacturers equally represented, with the members per team determined by the least represented manufacturer and an equal number of drivers from the other two manufacturers selected based on their final All-Star grid starting positions. Teams will be scored against each other and not by their overall All-Star finish. The lowest combined total of finishing positions will be the winning manufacturer. In the event of a tie, the single best overall finishing position will determine the winner.

The NASCAR All-Star Race will be 250 laps with a competition break at or near lap100 and an optional Promoter’s Caution that must be executed prior to lap 220. If the Promoter’s Caution has not yet occurred and a natural caution flag falls after lap 200, the optional caution will no longer be in play.

Saturday’s All-Star Open will give drivers who are not guaranteed a spot in the main event a chance to lock into the All-Star Race. The 100-lap Open will have a competition break at or near lap 40 and will not only determine which drivers advance to the main event but could also change the number of drivers eligible from each manufacturer for the Manufacturer Showdown. The three Open drivers who will advance to the All-Star Race are the top two race finishers and the Fan Vote Winner.

Drivers eligible for the NASCAR All-Star Race include those who’ve won a points event in either 2024 or 2025, drivers who’ve won a NASCAR All-Star Race and compete fulltime, and drivers who’ve won a NASCAR Cup Series championship and compete fulltime.
