Format Changes for 2026 Season
As previously announced, SRO America will also introduce a series of format evolutions across its major championships, aimed at enhancing competition:

For 2026, GT World Challenge America is set to debut a new three-hour race format at each round, replacing the traditional pair of 90-minute races. This change emphasizes strategy, teamwork, and race craft. As in previous years, the season will conclude with the marquee Indianapolis 8 Hour, remaining as the American championship’s crown jewel.

GT America will officially welcome Cup cars to its grids for the 2026 season. Race-prepped Porsche Cup, Lamborghini Super Trofeo, and Ferrari Challenge entries will join the series. Additionally, the Masters Award will return, celebrating the highest-finishing driver aged 55 and older at every event weekend.
TC America Powered by Skip Barber
TC America will see a refined schedule, shifting to a two-race, 35-minute sprint format per weekend. This adjustment aims to deliver fast-paced, action-packed racing while maintaining accessibility and affordability for teams and drivers.
Pirelli GT4 America
As the gold standard in GT4 competition, the series continues to maintain its consistent 60-minute doubleheader format at every round, preserving its reputation for creating close battles in multi-class racing. However, the popular three-hour Lone Star Enduro at Circuit of The Americas remains the exception, as the standout event makes a return for the third time.
