Race details
  • For 1925, riding mechanics were optional,[5] however, no teams utilized them.
  • First alternate: none[6]
  • Ralph DePalma would be the only driver in the race who had competed in the first Indy 500 in 1911.
  • Though Pete DePaolo is widely recognized as the first driver to complete (and win) the Indianapolis 500 in under five hours (over 100 mph average speed), he was not eligible for the prestigious Champion Spark Plug 100 mph Club founded in 1935. Since DePaolo briefly received relief help from Norman Batten during the race, DePaolo failed the strict criteria for the club. He never managed to complete the full 500 miles again, and accomplish the feat solo.
