IRL

The Indy Racing League, better known as IRL, is an American based open-wheel racing series sanctioning body.
The League sanctions two series, the premier IndyCar Series (abbreviated ICS; sometimes considered synonymous with the Indy Racing League), whose centerpiece is the Indianapolis 500, and Firestone Indy Lights, the official developmental series of the Indy Racing League.
The IRL is owned by Hulman and Co., which also owns the Indianapolis Motor Speedway complex and the Clabber Girl brand.
