USAC

The United States Auto Club (USAC), established in 1956, is a leading sanctioning body for auto racing in the United States, renowned for its open-wheel racing series such as sprint cars, midgets, and silver crown cars. These series, often held on short tracks, have been a proving ground for many drivers who later achieved success in IndyCar and NASCAR. USAC's history includes sanctioning the prestigious Indianapolis 500 for over four decades, cementing its place in motorsports lore. Beyond open-wheel racing, USAC also oversees a variety of other racing disciplines, reflecting its broad influence in the sport. Through its diverse series and commitment to driver development, USAC remains a cornerstone of American racing culture.
