NASCAR Xfinity to be rebranded as the O’Reilly Auto Parts Series

Xfinity has held the naming rights to NASCAR’s No. 2 division since 2015, but next year, it will be known officially as the NASCAR O’Reilly Auto Parts Series. The company will be the fourth brand to hold the naming rights to the popular series, which is the final stepping stone before the Cup level. The 33-race season is broadcasted exclusively on The CW, and has seen a notable rise in viewership this year (up 17 percent from 2024).

When the division first launched in 1982, it was originally called the Budweiser Late Model Sportsman Series before evolving into the NASCAR Busch Grand National Series. It was known as such from 1984 through 2002, when the name was shortened to the NASCAR Busch Series. In 2008, Nationwide took over as the entitlement sponsor until the end of the 2014 season.

“Like the great sport of NASCAR, O’Reilly Auto Parts was born in America and built on the hard work and drive of passionate people,” said NASCAR President Steve O’Donnell. “This new partnership allows us to continue to fuel that passion for the next generation of NASCAR’s stars and fans while celebrating the journey we’ve been on together for decades.”

This is a  multi-year deal with O’Reilly Auto Parts, and Xfinity will stay within the sport as a premier partner.

“Our company is rooted in the same values that define NASCAR—teamwork, enthusiasm, and dedication,” said O’Reilly Auto Parts President Brent Kirby. “You’ll see those in action when our customers walk through our doors. We know they need fast service, and Team O’Reilly will get them the parts they need quickly, with excellent customer service. We welcome all fans to stop by our stores and see how our team can help keep them running.” 

Xfinity released their own statement on social media, saying: “Congratulations to O’Reilly Auto Parts on becoming the next Xfinity Series sponsor in 2026. We’ve had an amazing 11 years & will always be fans of the series where names are made & look forward to watching what they do with this incredible sport. Thank you to the fans for their support.”
