NASCAR Cup Series at Dover Motor Speedway

The race is currently named Autotrader EchoPark Automotive 400 for sponsorship reasons, and is held in the summer.

Alex Bowman won the race in 2021 as part of a historic 1-2-3-4 finish for Hendrick Motorsports.

In September 2021, RelaDyne bought the Drydene brand which was the title sponsor of the race.

The company added another one of their brands, DuraMAX, to the title sponsor of the race.

As a result, in 2022, the name of the race became the DuraMAX Drydene 400 presented by RelaDyne.
