From 1950–1960, the Indianapolis 500 also counted toward the World Drivers' Championship (now synonymous with Formula One), although most of the racers did not compete in the other races in the Championship. Ruttman was the first Indianapolis 500 winner to participate in a Formula One event beyond Indy and his 1952 Indy 500 win earned him the distinction of being the youngest driver to win a round of the World Championship, an honor he held until Fernando Alonso won the 2003 Hungarian Grand Prix.
