Following realignment of the two Xfinity Series races, the Arizona 200 took over the November slot.

Whelen Engineering Company served as the title sponsor of the race in 2018.

[2] Desert Diamond Casinos and Entertainment served as the title sponsor of the race in 2019 and 2020.

[3] When they did not return in 2021, NASCAR did not set out to find a replacement title sponsor and instead named the race the NASCAR Xfinity Series Championship Race (in previous years, many fans would refer to the last race of the season by that name anyway regardless of what the official name of the race was).

In its four years as the last race of the Xfinity Series season, the driver who won the championship also won the race: Austin Cindric in 2020, Daniel Hemric in 2021, Ty Gibbs in 2022 and Cole Custer in 2023.
