DAYTONA BEACH, Fla. – On Saturday afternoon at Daytona International Speedway , a new era begins at Hendrick Motorsports as Corey Day kicks off the first full-time season in the NASCAR O’Reilly Series for the organization since 2006.

The 2026 NASCAR O’Reilly Auto Parts Series will begin on Saturday with the United Rentals 300. It’ll serve as an appetizer for Sunday’s Daytona 500, featuring the sport’s brightest young stars competing for a win this evening.

The United Rentals 300 runs as part of the NASCAR O'Reilly Auto Parts Series, formerly the Xfinity Series, ahead of the 2026 Daytona 500.

The No. 43 Inter Europol Competition Oreca will lead the LMP2 pack. The No. 3 Corvette and the No. 27 Heart of Racing Team Aston Martin will start first in the GTP Pro and GTD classes, respectively. Saturday's green flag will fly at 1:40 p.m. Here's the full grid.

After multiple postponements due to a winter storm, the NASCAR Clash is set for Wednesday night at Bowman Gray Stadium in Winston-Salem, N.C. Kyle Larson will be on the pole after setting the fastest time in qualifying this afternoon.

NASCAR Cup Series rookie Connor Zilisch goes from grandstands in 2022 to asphalt as a 19-year-old making his debut at Sunday’s Daytona 500.

NASCAR has moved the start of Sunday's 68th running of the Daytona 500 up an hour due to potential uncooperative weather.

The wait is finally over. The air in Florida is thick with anticipation and the scent of high-octane fuel because the 2026 NASCAR Cup Series season has officially arrived.
