First elimination
All cars may run. The slowest drivers are eliminated and take the lower grid positions, subject to penalties and any lap deletions.
Formula 1 weekends can use the standard qualifying structure or a sprint format. The biggest confusion is that sprint qualifying and the sprint race are separate from the grand prix grid procedure unless the weekend rules say otherwise.
The standard format is an elimination session: slowest cars drop out in Q1 and Q2, then Q3 decides the front of the grid.
All cars may run. The slowest drivers are eliminated and take the lower grid positions, subject to penalties and any lap deletions.
The remaining cars run again. Another group is eliminated, leaving the fastest drivers to fight for pole in Q3.
The final group decides the top qualifying positions. Pole can still be affected by grid penalties, deleted laps, or procedural offences.
