Del Roy was an American racing car constructor best known for making a single appearance at the Indianapolis 500 during the 1953 season. At the time, the Indianapolis 500 counted towards both the FIA World Drivers’ Championship and the Formula One World Championship, giving the small American constructor its place in Formula One history.

Although its World Championship involvement lasted for just one race, Del Roy was well admired within American motorsport for producing competitive sprint cars and dirt-track machinery in the years following the Second World War.
History
Founded in the post-war boom of American oval racing, Del Roy concentrated on building lightweight racing cars designed specifically for dirt tracks and sprint car competition. Rather than pursuing the expanding world of Grand Prix racing, the company focused on the uniquely American discipline of oval racing, where reliability and mechanical simplicity were just as important as outright speed.
The Del Roy name became closely associated with Frank “Frankie” DelRoy, one of the most respected mechanics and engineers in American motorsport. DelRoy earned an outstanding reputation as a chief mechanic before later serving as Technical Director of the United States Auto Club (USAC), where he helped shape technical standards for American open-wheel racing.
Indianapolis 500
Del Roy’s only appearance on the Formula One World Championship stage came at the 1953 Indianapolis 500.
The team entered a Del Roy-Offenhauser for experienced American driver Johnny Thomson, who successfully qualified for the race in 33rd position, the final spot on the starting grid.
Despite beginning at the back of the field, Thomson took the green flag and completed the opening stages of the race before mechanical trouble struck. An ignition failure forced the Del Roy into retirement after just six laps, bringing its Indianapolis—and Formula One—career to an early conclusion.
