Lloyd Ruby was one of the top USAC series drivers in the USA in the late 1950s and 1960s . A victory at the Indy 500 , however, was denied him. His best result was third in 1964. The closest he came to victory was in 1969 when he fell far behind while in the lead due to a completely botched last regular pit stop.
He celebrated his greatest successes in the sports car. In 1965 he won the Daytona Continental (a 4-hour race that was part of the Manufacturers' World Championship) and in 1966, each with Ken Miles as co-pilot, the 24 Hours of Daytona . In 1966 he also won the Sebring 12 Hours . He was part of the Ford works team at the Le Mans 24 Hours in 1967 . For Ruby, however, the race was over after just 86 laps, after an accident in which the Ford GT 40 MK IV was irreparably damaged. The co-pilot was Denis Hulme .
These statistics include all of the driver's participations in the World Automobile Championship, which is now known as the Formula 1 World Championship .
