NASCAR O'Reilly Auto Parts Series, one that will make the leader in the automotive replacement parts industry the title sponsor of what is now known as the NASCAR Xfinity Series. This landmark partnership aligns two American-born powerhouses, each with a rich legacy of fueling performance and passion from the grassroots up. The multi-dimensional sponsorship also includes promotional opportunities and brand integrations in partnership with The CW Network, the exclusive broadcast home of the NASCAR O‘Reilly Auto Parts Series.
The NASCAR O‘Reilly Auto Parts Series will officially debut on Jan. 1, 2026, ushering in a bold new chapter for the series crowded with NASCAR‘s future stars. The agreement marks the fourth entitlement sponsorship in the series‘ history, following a dynamic 11-year tenure with Xfinity that elevated the series to new heights with unprecedented fan engagement, innovation and exposure. The series‘ history also includes a seven-year run with Nationwide Insurance and a foundational relationship with Anheuser-Busch, still a current NASCAR partner at the Premier level.
The NASCAR O‘Reilly Auto Parts Series will be available exclusively to race fans across the country on The CW.
