IndyCar, LLC (stylized as INDYCAR), is an auto racing sanctioning body for American open-wheel car racing headquartered in Indianapolis, Indiana. The organization sanctions two racing series: the premier IndyCar Series with the Indianapolis 500 as its centerpiece, and the developmental series Indy NXT. IndyCar is recognized as a member organization of the FIA through the Automobile Competition Committee for the United States.
The sanctioning body was formed in 1994 under the name Indy Racing League by Hulman & Company, which also owned the Indianapolis Motor Speedway complex, and began competition in 1996. The trademark name INDYCAR was officially adopted on January 1, 2011. The sport of open-wheel car racing, also historically referred to as championship car racing or Indy car racing, traces its roots to as early as 1905. It is the fourth major sanctioning body to govern the sport of Indy car racing, following the American Automobile Association's Contest Board, the United States Auto Club (USAC), and Championship Auto Racing Teams (CART), and operated alongside the Champ Car World Series before acquiring the latter.
