1920

It was another unlucky 500 for Ralph DePalma, but a good day for the Chevrolet brothers (though Arthur Chevrolet had been badly injured earlier during practice). Gaston Chevrolet was driving a car built by brother Louis. It was a Frontenac, but was listed as a Monroe because an Indianapolis Monroe distributor financed the car.

DePalma was in the lead at lap 187 when his car caught on fire. He kept driving while his on-board mechanic, crawled out on the hood with a fire extinguisher. They finally had to stop, but the delay was costly. DePalma finished fifth that year.

Arthur Chevrolet recovered from his injuries, but gave up driving. Gaston Chevrolet died seven months later from injuries in a Pennsylvania race.
