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

Practice and qualifying are tentatively scheduled for eight Cup Series races this year. Busch Pole Qualifying was held for the season-opening Daytona 500; the next race with time trials scheduled is the March 28 event at Bristol Motor Speedway’s dirt track.
