Ontario Motor Speedway, located in Ontario, California, 40 miles (64 km) east of Los Angeles, was the first and only automobile racing facility built to accommodate major races sanctioned by all of the four dominant racing sanctioning bodies: USAC (and now IndyCar Series) for open-wheel oval car races; NASCAR for a 500-mile (800 km) oval stock car races; NHRA for drag races; and FIA for Formula One road course races.
