NASCAR O'Reilly Auto Parts Series at Charlotte Motor Speedway

The Charbroil 300 is an annual 300 miles (480 km) NASCAR O'Reilly Auto Parts Series race held at the Charlotte Motor Speedway in Concord, North Carolina that takes place during Memorial Day weekend as a support race for the NASCAR Cup Series' Coca-Cola 600.

Ross Chastain is the defending race winner, having won the event in 2026.

History

The race's origins trace back to 1978, when a NASCAR Late Model Sportsman Series race was held the day before the World 600. In 1982, it then became a Busch Series race.

From its inception through 2004, the race was scheduled for Saturday afternoon. In 1985 only, it was held the same day as The Winston. Lights were installed at Charlotte in 1993, and from 2005 to 2009, the race was a Saturday night race. In 2010, the race was moved back to the afternoon. Eastern in response to fans wanting an afternoon race and allowing for ABC coverage. In 2015, the race's broadcast was transferred to NASCAR on Fox after the departure of the NASCAR on ESPN content, allowing both of the races in Charlotte (the 300 on Saturday and the 600 on Sunday) to air on Fox.

In 2018, Alsco, a linen and uniform rental services company, became the entitlement sponsor for the race, dubbing it the Alsco 300. The name was tweaked in 2021 to become the Alsco Uniforms 300.

In 2024, BetMGM, a sports betting and online gaming platform jointly owned by MGM Resorts International and Entain, became the new title sponsor of the race.

In 2026, Charbroil took over the naming rights for the event.
