Sam Mayer entered the 2026 season with a singular goal: to add a third consecutive victory at Iowa Speedway. The defending champion has never lost on the 0.875‑mile oval, posting a 100% win rate after taking the checkered flag in both 2024 and 2025. His perfect record has made him the first driver to secure a win for the newly formed Haas Factory Racing program in 2025, a milestone that adds extra intrigue to his upcoming attempt.
A Perfect Record at Iowa
Mayer’s dominance is not an accident. The track’s unique combination of short‑track grit and strategic pit work suits his aggressive yet calculated style. After claiming the 2025 victory, he became the first driver to win the race for Haas Factory Racing, a team that has quickly risen to prominence in the series. His confidence is bolstered by a career‑long affinity for the venue, where he has never finished outside the top three.
The competition, however, remains fierce. Christopher Bell has won all four of his New Hampshire starts in the series, while Connor Zilisch has taken all three of his Watkins Glen victories. Shane van Gisbergen, a multiple‑time winner on the Chicago Street Course, and Chandler Smith, who has repeatedly excelled at Richmond, round out a field of drivers who each possess a track where they have historically thrived. Their presence ensures that Mayer’s perfect record will be challenged from the moment the green flag drops.
Chase Implications and Upcoming Races
The points battle adds another layer of drama. Three Joe Gibbs Racing drivers — Brent Crews, Taylor Gray, and William Sawalich — currently occupy the top spots, with Sawalich trailing Gray by seven points. Allgaier, a former Iowa winner in 2018, is returning to the track and has secured top seeding in the NASCAR Cup Series Chase, which kicks off at Darlington Raceway on September 5. The stakes are high, as a strong performance at Iowa could reshape the playoff picture.
Adding to the narrative, Rajah Caruth is set to return to the No. 88 JRM ride after a stint with Jordan Anderson Racing. Caruth expressed excitement about the track’s recent changes, noting that the updated layout could favor a different strategic approach. The 23rd race of the O’Reilly Auto Parts Series at Iowa Speedway marks the event’s return after a four‑year absence, promising a weekend steeped in tradition and anticipation.
