The Indy Racing League, or INDYCAR, is an American-based auto racing sanctioning body for Championship auto racing. The organization sanctions four racing series: the premier IndyCar Series (often abbreviated ICS) with its centerpiece Indianapolis 500, and developmental series Indy Lights, the Pro Mazda Championship and the U.S. F2000 National Championship, which are all a part of The Road To Indy.
Other sanctioning bodies have similarly different definitions.
A partial list of classes includes:.
The trade name INDYCAR was officially adopted on January 1, 2011.
INDYCAR is owned by Hulman & Company, which also owns the Indianapolis Motor Speedway complex and the Clabber Girl brand.
The League's premier series was named the Indy Racing League IndyCar Series in 2003. In 2013, IZOD announced that they would be leaving the series. Verizon took over as title sponsor in 2014, and the name became the Verizon IndyCar Series.
IZOD was announced as the series title sponsor beginning on November 5, 2009. Exact financial terms were not disclosed but the deal is worth at least $10 million per year and runs for at least 5 years. IZOD ended its sponsorship after the 2013 season.
The series initially raced exclusively on oval tracks, as the series was founded partly in response to the increasing prominence of road and street courses on the CART schedule. In 2005, the series abandoned its unofficial ovals-only stance, and added three road–street course events. By 2009, the series had a roughly 50/50 split of ovals and road/street courses. Presently, the series currently runs one-third of its schedule on ovals and the rest on road and street circuits.
Indy Lights is the development series for the IndyCar series. It originally started in 2002, as the IRL Infiniti Pro Series coincidentally in the same year as CART's own Indy Lights series came to an end. Since the 2008 reunification, the Indy Lights name returned. The Indy Lights run as support races to IndyCar Series races. In the past, a round during the United States Grand Prix was also apart of the schedule, and the League also added a stand-alone race as part of the Grand Prix de Trois-Rivieres. The series is now promoted by Andersen Promotions.
Indy Lights is an American developmental automobile racing series sanctioned by IndyCar, formerly known as Firestone Indy Lights for sponsorship reasons. Previously, another series named Indy Lights filled the same role for CART and ran from 1986 to 1993 as the American Racing Series and Dayton Indy Lights from 1991 to 2001. The IndyCar sanctioned current series was founded in 2002 as the Infiniti Pro Series as a way to introduce new talent to IndyCar and coincided with Infiniti's departure from IndyCar's premier IndyCar Series.
