2026 GT4 America Calendar

Pirelli GT4 America is the premier North American sprint racing series for GT4-spec machinery. The championship is designed to provide a cost-effective yet highly competitive platform for both professional and amateur drivers, featuring a massive variety of manufacturers including Porsche, BMW, Aston Martin, and McLaren. The series follows a two-driver format consisting of two 60-minute sprint races per weekend, with a mandatory mid-race pit stop and driver change. Competition is split into three primary classes based on driver categorization: Silver, Pro-Am, and Am. With a schedule that visits North America's most iconic road courses such as Sonoma, Road America, and Indianapolis, GT4 America serves as a vital stepping stone in the GT racing ladder, emphasizing driver development and intense, manufacturer-backed wheel-to-wheel competition.
