Description

The INDYCAR Series is an Open-Wheel racing sporting event. The INDYCAR Series is an American-based auto racing sanctioning body for Indy car racing and other disciplines of open wheel car racing. 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 ACCUS. 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 itself, also historically referred to as Championship Car racing or Indy racing, traces its roots to as early as 1905. It is the fifth major sanctioning body to govern the sport of Indy car racing, following AAA, USAC, CART, and Champ Car.
