The 15th International 500-Mile Sweepstakes Race was held at the Indianapolis Motor Speedway on Monday, May 30, 1927.

[4] After Lockhart's retirement, Pete DePaolo took the lead, driving in relief for Bob McDonogh after his own car dropped out.

But a supercharger problem required an extended, unscheduled pit stop to repair.

He steadily pulled away from Babe Stapp, both in Duesenbergs, and cruised to victory by over 12 minutes.

Stapp (driving relief for Benny Shoaff), seemingly on his way to second place, broke a rear axle with a lap and a half to go, and the car finished out of the top ten.
