Pirelli GT4 America has firmly established itself as one of North America’s premier series for professional sports car racing, with an ultra-competitive field defined by manufacturer diversity, tight multi-class racing, and full-capacity grids at nearly every round. The championship continues to grow while also remaining a cornerstone of SRO America’s success and a global benchmark for the GT4 platform.
Few championships consistently attract the level of interest that Pirelli GT4 America does. Year after year, the series fills its entry list with a robust roster of teams and drivers ranging from emerging talents to seasoned pros.
The GT4 platform’s accessibility and global notoriety help sustain this momentum. High-quality customer and factory-supported racing programs make participation viable and competitive across the board, directly contributing to higher car counts and evolving storylines that define the championship.
It also continues to stand out as a melting pot of automotive engineering, with grids featuring a wide array of performance manufacturers, from European staples like BMW, Mercedes-AMG, and Aston Martin, alongside agile entries from Japan in Toyota, and now with an American contender joining the ranks with the likes of Ford.
This broad representation deepens the competition. Different drivetrains, chassis styles, and aerodynamic packages converge under the global GT4 banner, producing wheel-to-wheel battles where the outcome is decided on execution rather than machinery.
Operating as the gold standard in GT4 competition, the championship’s format remains one of its greatest strengths. The 60-minute doubleheader structure at every round ensures that there is no shortage of action, all while maintaining feasible race lengths that encourage sprint-style intensity. Teams must master driver changes, tire management, and close-quarters combat, mixed in with navigating traffic from multiple classes.
The season’s crown jewel, however, is the three-hour Lone Star Enduro at Circuit of The Americas. Returning in 2026 for its third edition, the event stands as a beloved exception to the sprint format. It has quickly become a fan and competitor favorite for its extended race length, adding extra strategic depth and a unique twist to the championship.
With Silver, Pro-Am, and Am classes sharing the track, the series delivers some of the tightest racing in North America. Drivers must balance risk versus reward, and the multi-class dynamic provides an element of unpredictability. The constant interplay between classes ensures that no race is ever linear as momentum can swing lap by lap.
Pirelli GT4 America continues to thrive because it delivers variety, unpredictability, and a deep field where any team can shine when they’re able to capitalize on the opportunity. With strong grids, manufacturer battles and a diverse representation of brands, and close racing that leaves virtually no margin for error, Pirelli GT4 America remains one of the best and most exciting series under the SRO America umbrella, and the competition is alive and well heading into the upcoming season.
