IndyCar.

IndyCar is the trade name of an American-based open-wheel auto racing sanctioning body. IndyCar sanctions three racing series, the premier IZOD IndyCar Series with its centerpiece Indianapolis 500, and developmental series Firestone Indy Lights and the U.S. F2000 National Championship, which are both a part of The Road To Indy.

The trade name INDYCAR was officially adopted on January 1, 2011, as the trade name of racing operations of Indy Racing League LLC.
IndyCar is owned by Hulman and Co., which also owns the Indianapolis Motor Speedway complex and the Clabber Girl brand.The IndyCar Series is the name adopted in 2003 for the premier series sanctioned by IndyCar. The series was known as the Indy Racing League until the beginning of the 2003 season. Izod was announced as the IndyCar Series title sponsor in 2010, a deal expected to run for at least five years.USF2000 is a series IndyCar started sanctioning in 2010. Originally started in 1991 and folded in 2006, it was restarted in 2010 as part of the "Road to Indy" ladder series. The series runs with Star Mazda at every event, though it doesn't run at a few races Star Mazda does.IndyCar was also the first racing series to adopt the SAFER soft wall safety system, which debuted at the Indianapolis 500 and has now been installed at almost all major oval racing circuits. Recognized as one of the most significant improvements in racing safety, the SAFER system research and design was supported and funded in large part by the Hulman-George family and the Indianapolis Motor Speedway. The system's full name, Steel And Foam Energy Reduction, accurately explains the method used to attenuate high-G impacts that in the past led to serious driver injuries.
