The Würth 400 is a NASCAR Cup Series stock car race held annually at Dover Motor Speedway in Dover, Delaware in the spring. History The 2020 race was postponed to August due to the COVID-19 pandemic and became a doubleheader with the second race. Both events were named the Drydene 311 as their race lengths were shortened. For 2021, the race length was restored to 400 miles. 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. RelaDyne was also included in the name of the race as a presenting sponsor. As a result, in 2022, the name of the race became the DuraMAX Drydene 400 presented by RelaDyne. In 2023, Würth, which has been a sponsor on Team Penske's NASCAR Cup and Xfinity Series cars for a few races each year since 2012, became the title sponsor of the "Monster Mile" race.
