Chevrolet completed the sweep of the manufacturers’ championship in all three NASCAR national series by clinching the Cup series honor at Martinsville Speedway.

It is the third consecutive year Chevrolet has won the manufacturers’ championship in the Cup Series and their 42nd overall. Chevrolet previously clinched in both the Craftsman Truck series and Xfinity series Oct. 21 at Homestead-Miami Speedway.

“Chevrolet is honored to win the 2023 NASCAR Cup series manufacturer championship for the third consecutive year and the 42nd time overall,” said Jim Campbell, General Motors U.S. vice president of performance and motorsports. “This title is the result of great teamwork by the Chevrolet drivers, crew chiefs, and teams working tirelessly throughout the season.”

Chevrolet has won 17 races with seven different drivers and started the year winning the Daytona 500 with Ricky Stenhouse Jr. It was their first win in the Daytona 500 since 2018 with Austin Dillon.

William Byron has a series-leading six victories in the No. 24 Hendrick Motorsports Chevrolet.

“Winning the Manufacturer Championship in the NASCAR Cup Series is a remarkable achievement,” said Megan Brobeck, GM Racing program manager for the NASCAR Cup series. “We are very proud of the dedication and cooperation among Chevrolet’s teams and engineers, and their efforts all season long paid off with this special honor. Congratulations to all who contributed to the championship for this much-deserved accomplishment.”

Chevrolet will have two drivers racing for a championship in the finale at Phoenix Raceway. Byron and teammate Kyle Larson both advanced for Hendrick Motorsports.
