The NASCAR team owned by Hall of Famer Dale Earnhardt Jr. will attempt to make its Cup Series debut in the Daytona 500 with a champion driver and a partnership with a Grammy Award-winning artist. JR Motorsports has entered reigning Xfinity Series champion Justin Allgaier into next month’s season-opening “Great American Race” in a Chevrolet sponsored by the whiskey label created by 10-time Grammy winner Chris Stapleton. Allgaier will have to qualify for the Daytona 500 — a race his boss has won twice — on either speed in time trials or via one of the qualifying races.
