Sam Mayer returns for the 2025 season as driver of the No. 41 Haas Factory Ford Mustang in the NASCAR Xfinity Series. The 21-year-old Mayer capped his third full-time season with JRM in 2024 with three victories, 8 top-five and 13 top-10 finishes. The 2024 season marked Mayer’s third straight as a NASCAR Xfinity Series Playoff participant.
Long noted as a road-course ace, Mayer was a force on the twisty tracks in 2023. He captured his first career NXS victory at Road America, not far from his hometown of Franklin, Wis. Mayer battled near the front all day and survived a wild ending sequence, taking the lead for the final time off the last corner and out-dragging Parker Kligerman to the checkered flag.
Mayer leveraged his Late Model prowess into a place on national stage when he joined GMS Racing to compete in the NASCAR K&N Pro Series, ARCA Series and NASCAR Craftsman Truck Series. Running the full 2019 schedule in the K&N Pro Series East, Mayer scored four wins, 11 top fives and 11 top 10s en route to a championship that made him the youngest champion in any NASCAR series at the age of 16 years, three months and eight days.
In 2020, Mayer turned even more heads when he drove to his first career NCTS victory at Bristol Motor Speedway in only his sixth series start. Add in a combined 11 wins across all three ARCA Menards Series’ en route to the Sioux Chief Showdown championship and the ARCA Menards Series East championship, and Mayer was poised for a robust return to JRM in 2021. He ran 17 races in the team’s No. 8 Chevrolet, splitting time with teammate Berry in the car.
In 2022, Mayer, in his first full-time season with JRM, added a Dash 4 Cash win to his list of accomplishments at Richmond Raceway in the spring and scored a runner-up finish at Talladega Superspeedway in the fall.
