The 1915 AAA Championship Car season consisted of 27 races, beginning in San Diego, California on January 9 and concluding in San Francisco, California on November 25. AAA did not award points towards a National Championship during the 1915 season, and did not declare a National Champion. [1] Ralph DePalma was the winner of the Indianapolis 500.
The de facto National Champion as polled by the American automobile journal Motor Age, was Earl Cooper. Points were not awarded by the AAA Contest Board during the 1915 season. Cooper was named the champion by Chris G. Sinsabaugh, an editor at Motor Age, based upon merit and on track performance. A points table was created retroactively in 1927. At a later point, it was recognized by historians that these championship results should be considered unofficial.

Melvin Eugene "Tony" Bettenhausen was an American racing driver known primarily for his open-wheel career. He twice won the National Championship, doing so in 1951 and 1958. He also competed in stock cars, winning under AAA and USAC sanction.
John Ashley Thomson was an American racecar driver. Thomson was nicknamed "the Flying Scot." He won several championships in midgets and sprint cars before competing in Championship Car racing. He won the pole position for the 1959 Indianapolis 500.
John Donald Aitken was an American racing driver from Indianapolis, who was active in the years prior to World War I. Aitken competed in the Indianapolis 500 three times. He started the race twice, in 1911 and 1916. He led the first lap of the first race (1911). Aitken captured the pole position in 1916, but ended up in 15th place that year. In the 1915 Indianapolis 500, Aitken drove relief for two drivers, Gil Anderson and Earl Cooper.
The 1915 Grand Prix season saw Grand Prix motor racing continue in the United States. Racing was suspended in Europe due to the outbreak of World War I. The American Grand Prize was held in San Francisco for the first time, in conjunction with the Panama–Pacific International Exposition. Several of the latest European cars had been imported to the USA before the war started. Briton Dario Resta had a Peugeot and Ralph DePalma raced one of the Mercedes GPs. While Resta won both races at San Francisco and DePalma won the Indianapolis 500, just ahead of Resta it was Earl Cooper, running a Stutz, whose consistency gave him the unofficial AAA national championship.
The 1955 AAA Championship Car season consisted of 11 races, beginning in Speedway, Indiana on May 30 and concluding in Phoenix, Arizona on November 6. There was also one non-championship event in Mechanicsburg, Pennsylvania. The AAA National Champion and Indianapolis 500 winner was Bob Sweikert. Manny Ayulo was killed at Indianapolis while practicing for the 1955 Indianapolis 500, and Bill Vukovich, the two-time defending winner, was killed in the race itself. Jack McGrath, the two-time champion, was killed in the final race at Phoenix on lap 85. This was the last year of the AAA National Championship; USAC sanctioned the series starting the next year.
The 1909 AAA Championship Car season consisted of 24 races, beginning in Portland, Oregon on June 12 and concluding with a point-to-point race from Los Angeles, California to Phoenix, Arizona on November 6.

AAA did not award points towards a National Championship during the 1909 season, and did not declare a National Champion.
The 1910 AAA Championship Car season consisted of 19 races, beginning in Atlanta, Georgia on May 5 and concluding in Long Island, New York on October 1. AAA did not award points towards a National Championship during the 1910 season, and did not declare a National Champion.

There was also one non-championship event in Mechanicsburg, Pennsylvania. The AAA National Champion was Tony Bettenhausen, and the Indianapolis 500 winner was Lee Wallard.

After four years without racing in the United States, the AAA Contest Board was initially concerned about having enough races, enough entrants, and suitable equipment, for a 1946 season. Even the Indianapolis 500 was in doubt, as the Indianapolis Motor Speedway had been neglected during the war.
The 1921 AAA Championship Car season consisted of 20 races, beginning in Beverly Hills, California on February 27 and concluding in San Carlos, California on December 11. There was also one non-championship race. The AAA National Champion and Indianapolis 500 winner was Tommy Milton.
