The event was to have been the penultimate race of the 2003 season, but it later became the final round after the 2003 King Taco 500 was canceled because of a wildfire near to the California Speedway venue. In December 2003 the CART World Series declared bankruptcy and as a result went out of business. Therefore, this race became the final completed CART sanctioned event, although the series would be reborn under new ownership as the Champ Car World Series in 2004.
