Dale Earnhardt Jr.'s JR Motorsports is making its NASCAR Cup Series debut at the 2025 Daytona 500 with Justin Allgaier behind the wheel of the No. 40 Chevrolet.

For the first time in JR Motorsports history, the team co-owned by two-time Daytona 500 winner Dale Earnhardt Jr. and his sister Kelley Earnhardt Miller will field an entry in the Daytona 500 with NASCAR Xfinity Series champion Justin Allgaier as the driver.

JR Motorsports has run in the second-tier Xfinity Series since 2006, but a Daytona 500 attempt with Justin Allgaier marks the team's first-ever Cup Series entry.
