History


IndyCar name

The term "Indy car" began as a nickname for the cars that competed in the USAC's Championship Division of

Indianapolis 500 The Indianapolis 500, formally known as the Indianapolis 500-Mile Race, and commonly shortened to Indy 500, is an annual automobile race held at the Indianapolis Motor Speedway in Speedway, Indiana, United States, an enclave suburb of Indian ...
. The division's link with Indianapolis soon resulted in the term surpassing the official term "championship car" (or its short form "champ car") in common use and promotions. The term continued to be used by the USAC's replacement as the dominant governing body for open-wheel racing, CART, which called its main series the "CART PPG Indy Car World Series" despite the body not sanctioning the 500. In 1992, during an attempt by CART to broaden their board membership, the Indianapolis Motor Speedway registered the

against the Indianapolis Motor Speedway in an effort to protect their license to the ''IndyCar'' mark after the Indianapolis Motor Speedway had attempted to terminate it. In April, the Indianapolis Motor Speedway filed a separate lawsuit against CART to prevent them from further use of the mark. Eventually a settlement was reached in which CART agreed to give up the use of the ''IndyCar'' mark following the 1996 season and the IRL agreed not to use the name before the end of the 2002 season. CART returned to branding as simply CART for 1997, and resurrected the term "champ car" to describe their vehicles. Following a six-year hiatus, the Indy Racing League announced it would rename their premier series the IndyCar Series for the 2003 racing season. CART, beset by team departures and other financial issues, filed for bankruptcy that year; a trio of former CART team owners were selected by the bankruptcy court to purchase CART's assets, which they used to reorganize the

Split with CART

The dispute between CART and IRL centered on the Indianapolis 500, long considered the flagship race of the sport. From 1980 until 1995, USAC continued to sanction the Indy 500, although CART drivers predominantly competed in the race and points that drivers scored during the event counted towards the CART drivers' championship. George felt that his opinions regarding increasing costs and revenue sharing were being ignored, while CART team owners felt George used his influence over USAC to have a disproportionate impact on the general operation of the sport. After a number of attempts at a compromise board failed, IMS formed the Indy Racing League in

George blueprinted the IRL as a lower-cost open-wheel alternative to CART, which in his view had become technology-driven and dominated by a few wealthy multi-car teams.
