The season will end with the Folds of Honor QuikTrip 400 at Atlanta Motor Speedway on December 14, 2020. Adam Petty enters as the defending series champion.

This is the final season for part-timer Brendan Gaughan, veterans Blaise Alexander and Jimmie Johnson, as well as the Strictly Stock Car II, as a new car, dubbed the Strictly Stock Car III, is slated to debut in 2021.

Manufacturer changes

 * Mercury, Oldsmobile, and Studebaker will re-enter NASCAR competition, fielding the Sable, Cutlass, and Commander, respectively.
 * JTG Daugherty Racing and Premium Motorsports will switch to Dodge, marking the return of the Charger to the Cup Series; the Charger last ran in the Cup Series in 2012, and had been running in the Grand National Series (without factory support until 2017), as well as being the primary Dodge model in the K&N Pro Series and ARCA Racing Series.
 * Chevrolet upgraded the Camaro ZL1 to the ZL1 1LE model. The change was made primarily due to the pointed nose of the base ZL1 causing large multicar wrecks at Daytona and Talladega when attempting to push.

Changes due to the coronavirus (COVID-19) pandemic

 * On March 16, 2020, NASCAR announced all race events through May 3 have been postponed due to the coronavirus (COVID-19) pandemic. CEO Trevor J. Simpson ultimately decided to run doubleheaders later in the season. To facilitate this, he ordered Talladega Superspeedway to install a lighting system so the GEICO 500 could be run after the Sugarland Shine 250 SuperTruck race, then run the 1000Bulbs.com 500 the next day.
