Both Lincoln and Lancia came to the race highly organized and both factories swept 1-2-3 finishes in their respective categories. The Mercedes team did not return because of its focus on Formula One. The Europeans dominated the sports categories, and the Americans the stock. Large Sports Cars was won by Juan Manuel Fangio of Argentina in a Lancia, Small Sports Cars by José Herrarte from Guatemala in a Porsche. Large Stock Cars was won by Chuck Stevenson of the United States in a Lincoln and Small Stock Cars by C.D. Evans (again of the U.S.) in an ordinary six cylinder Chevrolet. Stevenson has the distinction of being the only person to ever win twice in the same category in the original race.
