Chase Briscoe (23.676), Kyle Busch (23.697), Tyler Reddick (23.707), Chase Elliott (23.749), and Christopher Bell (23.884) were the five fastest drivers from Group A qualifying. Bell will have to start from the rear of the field after crashing in practice and going to a backup car.

With rainfall delaying Cup qualifying by nearly one hour, NASCAR altered the session. The drivers still went out in two separate groups, but there was no final round.

The fastest five drivers from Group A and Group B formed the top 10 of the starting lineup. The rest of Group A formed the outside lane. The rest of Group B formed the inside lane.

The track was green, which resulted in some close calls for multiple drivers. Erik Jones, Corey LaJoie, Bubba Wallace, Martin Truex Jr., and others began to lose control at various points in their laps. This impacted their lap times.

Austin Dillon had the slowest lap in the session at 24.891 seconds and 126.552 mph. He was the first driver out on the green track, and he gave the other drivers an idea as to what they could and could not do while racing for the pole.

The first stage of Sunday's race will be 70 laps. The second stage will be 140 laps. The final stage will be 140 laps.

The green flag for Sunday's inaugural Cup Series race at Iowa Speedway will wave at 7:05 p.m. ET. The command to fire engines will be at 6:58 p.m. ET. USA Network will provide coverage for the first time this season with Rick Allen, Steve Letarte, and Jeff Burton in the booth.
