Harvest Auto Racing Classic

The Harvest Auto Racing Classic was a series of three automobile races, held at the Indianapolis Motor Speedway on Saturday September 9, 1916, four months after the 1916 Indianapolis 500.

Race history
The Harvest Classic was a unique event in the history of the Indianapolis Motor Speedway. During 1909 and 1910, the track had held auto race weekends which consisted of from 16 to 24 races, involving several different classes of cars. Starting with 1911, a different promotional strategy was initiated, and the track held only one race annually, the Indianapolis 500. The track adhered to this plan of one race per year from 1911 to 1993, with one exception. In 1916, with the United States on the verge of entering World War I, track management foresaw the possibility that the track may have to shut down the following year. In an effort to generate some additional profits, to get through the down time, the track held an additional event in September. This consisted of three races, all for the same class of cars (the same cars as were used in the Indianapolis 500). The event was sanctioned by AAA, and the 100 mi feature race counted toward the 1916 National Championship.

The two preliminary races each paid separate prize money, and neither served as a "heat" race, or qualifying race, for the longer, 100-mile feature, nor did they pay points towards the national championship. Johnny Aitken swept all three races.

INDYCAR Harvest GP
On April 6, 2020, the IndyCar Series announced that as part of further revisions to the 2020 schedule due to the coronavirus pandemic, it would add a third race at IMS to the schedule known as the INDYCAR Harvest GP, as a road course race on October 3. Its naming pays tribute to the Harvest Auto Racing Classic, and the race will serve as a support event for the (accompanying the inaugural Indianapolis 8 Hour on the Intercontinental GT Challenge circuit). It will be the second road course race at IMS for the 2020 season, accompanying the GMR Grand Prix (which is tentatively scheduled for July 4 as part of NASCAR's Brickyard 400 weekend).
