From an early age, McQueen was an avid enthusiast of automobile, motorcycle, and racing, interests that he inherited from his Father, Steve. He began racing dirt bikes by age nine and, in three years, would go on to win his class in the World Mini Grand Prix. He quickly moved on to auto racing, winning his first race: the Mini Le Mans event, a children-only track created on the set of the 1971 film Le Mans, when McQueen was ten years old. Before filming was completed on that film, McQueen enjoyed racing at triple digit speeds down the straights while seated in his father's lap at the wheel of a Porsche 917. At 12, he won his class at the World Mini Grand Prix.
