|The series went on hiatus from 1942-1945 due to World War II.|
The 1946 season was the first season back after World War II, the AAA Contest Board, in fear of having low car counts, decided to count the 6 events of the 1946 AAA Champ Car Series as part of the season. Thus making the event count 77 races for the season. The car counts did not suffer as expected, so in December of 1946 the Contest Board decided to only count the initial 71 races scheduled. Official records only count these 71 races and therefore we will only count those races for the 1946 season.
Following the closure of the AAA Contest Board after the 1955 season, the United States Auto Club was formed and took over the series. Thus starting the, statistically separate, USAC Sprint Car Series.
