The list of "Indy car" or "Champ car" rookies under the following auspices:
The AAA Contest Board began sanctioning races as early as 1904. In the early years of the sport, only two seasons (1905 and 1916) an official national championship was recognized and awarded. The 1946 season is a source of a statistical anomaly. The AAA Contest Board included a substantial number of "Big Car" races in the national championship for 1946, swelling the season to 77 events (6 Champ Car races and 71 Big Car races). Some later texts chose to dismiss the 71 Big Car races from record, but reliable records and historians contend that the season should be regarded as the full 77-race schedule.
