Where West Coast Open Wheel Championships Converge:
Mark your calendars for May 15-17, 2026, as Thunderhill Raceway Park hosts a motorsports experience unlike any other. This three-day festival brings together the West Coast's top open-wheel formula talent alongside a thriving car culture showcase.
Far from a traditional race weekend, The Thunderhill Open offers a unique mix of road racing, drift competitions, and entertainment. Described as a "chaotic, fun mix" of speed and humor, the event features heat races, judged drift battles, and our signature "Caddyshack-style" awards ceremony—where champions are honored not with trophies, but with our coveted Green Jackets.
