List of American Championship Car winners

The following is a list compiling the total number of career victories in open wheel American Championship car racing.

The list recognizes IndyCar or Champ Car victories under the following auspices: Colton Herta is the youngest winner of a major American open-wheel car race; he was 18 years, 11 months and 25 days old when he won the 2019 IndyCar Classic.

[1] Louis Unser is the oldest winner of a major American open-wheel car race; he was 57 years, 5 months and 22 days when he won the 1953 Pikes Peak International Hill Climb.

Individual events from 1904, 1906–1915, and 1917–1919 are specifically excluded from the table below, due to the fact that they were not part of an official "championship" season.

Retroactively awarded titles for the other years were later researched, although most historians consider them to be revisionist, and do not deem them as suitable for official record.

For 1996–1997, victories in the Indianapolis 500 and Indy Racing League are listed solely under the heading of IndyCar.
