The Indy Racing League (IRL) is an American-based open-wheel auto racing sanctioning body. The League sanctions three racing series. The premier IZOD IndyCar Series (ICS),[1] the two developmental series; Firestone Indy Lights and the U.S. F2000 National Championship. ICS is sometimes considered the same as the Indy Racing League. The Indy Racing League's centerpiece race is the Indianapolis 500.
The IRL is owned by Hulman and Co., which also owns the Indianapolis Motor Speedway complex and the Clabber Girl brand.
On September 10, 2010, the IRL announced that effective January 1, 2011, the Indy Racing League will simply be known as IndyCar.[2]
