Motor racing at the Summer Olympics
Motor racing has been featured at the Summer Olympics twice, though neither time as a full medal event. In 1900, it was a sport at the 1900 World's Fair like all other Olympic events, but has generally not been considered official. In 1936, an unofficial "Olympic Rally" was held, with prizes awarded.
