As NASCAR adapted to COVID-19 protocols last season, practice and qualifying were eliminated at a majority of national-series events to limit at-track time, exposure and to cut race weekend costs. To determine starting lineups, competition officials used grouped draws, added inversions for weekend doubleheaders, and eventually adopted a performance-metrics formula. That metrics format remains in place this season, drawing on performance from both individual races and season-long results.

NASCAR’s metrics formula for 2021 weighs:

• 25 percent: Driver’s finishing position from the previous race

• 25 percent: Car owner’s finishing position from the previous race

• 35 percent: Team owner points ranking

• 15 percent: Fastest lap from the previous race

See the full lineup for Sunday’s Cup Series race below.

Practice and qualifying are tentatively scheduled for eight Cup Series races this year. Just one race remains with Busch Pole Qualifying on the schedule — the season-ending championship race Nov. 7 at Phoenix Raceway.
