SRO America has revealed its provisional 2027 calendar, featuring seven race weekends located across North America's premier circuits, including the return of a legendary venue and a marquee event change. The three-hour regular season race format, which was introduced in the 2026 season, will continue for the upcoming year as well, with the exception of one eight-hour spectacle.  

As in previous years, the season will begin on the West Coast at Sonoma Raceway before heading to Circuit of The Americas, where competitors will contest the inaugural Texas 8 Hour. The event replaces the long-running season-finale Indianapolis 8 Hour and marks an exciting new chapter for GT World Challenge America and Intercontinental GT World Challenge competition.  

Following COTA, the championship will return to Watkins Glen International in upstate New York. One of the most iconic road courses in North America, Watkins Glen joins the schedule for the first time since 2022. 

Road Atlanta returns to the calendar after the series came back to the Georgia track this year for the first time since 2011, enjoying a successful return before the series takes its traditional summer break. Competition resumes at Road America with the fan-favorite full field parade through Elkhart Lake, followed by Barber Motorsports Park as the penultimate event on the schedule. 

The season finale will take place at Indianapolis Motor Speedway in October, bringing the championship battles to a close at one of the world's most renowned and historic venues. 

The 2027 schedule continues SRO America's commitment to delivering world-class GT racing across the country while introducing fresh, new opportunities for teams, drivers, and fans.
