The NASCAR Xfinity Series will become the NASCAR O’Reilly Auto Parts Series in 2026, NASCAR announced Aug. 18.
NASCAR and O’Reilly Auto Parts have entered into an agreement for the company to replace Xfinity as the entitlement sponsor of the sanctioning body’s second-tier national series after this season.
The sponsorship is for multiple years, though the exact length was not disclosed. This will put O’Reilly as the sponsor through at least the end of 2027.
“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,” NASCAR President Steve O’Donnell said in a release. “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.”
“Our company is rooted in the same values that define NASCAR — teamwork, enthusiasm and dedication,” O’Reilly Auto Parts President Brent Kirby added. “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.”
The change follows an 11-year tenure for Xfinity as the series’ sponsor, having taken over from Nationwide, which was preceded by Busch.
The status of the Xfinity Fastest Lap award, which stretches across all three national series, is unclear.
Kevin Rutherford is the executive editor of Frontstretch, a position he gained in 2025 after being the managing editor since 2015, and serving on the editing staff since 2013.
At his day job, he's a journalist covering music and rock charts at Billboard. He lives in New York City, but his heart is in Ohio -- you know, like that Hawthorne Heights song.
People who give old school/former fans heck for still calling them Busch cars better make sure they have their labels all memorized. Wouldn’t want to be seen as not being “with it.”
Yeah, I’ll respond to Xfinity, Grand National, Busch, and now, O’Reilly. Not quite old enough to have been around for when it was the Sportsman series.
Hopefully, O’Reilly stops putting some sort of perk on using a series catchphrase. I cringe every time I hear “my car was as fast as Xfinity internet today” during a driver interview.
Ya wanna drink a Coke during an interview to get perks, have at it. At least it doesn’t take up interview time.
Don’t forget Late Model Sportsman!
You can’t drink a Coke if the event is sponsored by Pepsi!
Remember that nonsense they went thru putting Gatorade signage and the chaos that ensued when HMS cars won?
Was it Jeff Gordon who had the pop knocked off the roof of his car in VL?
New slogan: O’Really. Faster than I can drink a six pack.
The drivers will have to sing O O O’Reilly
The name was changed to protect the guilty!
Who’s guilty?
NA$CAR for having to get new series sponsors when the ROI isn’t what was promised by NA$CAR’s numbers.
I hated hearing the drivers say my car was faster than Xfinity 5g
Oh.really? No! O’Reilly!
