[8] This ended up being the last Clash race in its traditional form; the event moved to the road course for 2021 (originally planned as the last race for the Generation 6 car; the car was used for the entire season instead) and then to the Los Angeles Memorial Coliseum in 2022.

The 2020 Busch Clash will not be a predetermined number of cars; rather, the field is limited to drivers who meet more exclusive criteria.

Although Daniel Hemric and Daniel Suárez were eligible to run the event, they chose not to run with Hemric moving back to the NASCAR Xfinity Series and Suarez focusing in preparing for the 2020 Daytona 500.

[9] Erik Jones was the fastest in the final practice session with a time of 45.055 seconds and a speed of 199.756 mph (321.476 km/h).

FS1 covered the race on the television side; Mike Joy and Jeff Gordon handled the call in the booth for the race; Michael Waltrip, Vince Welch and Matt Yocum handled pit road for the television side.
