IndyCar is the highest class of American open-wheel racing, founded in 1920. The series runs single-seater sprint racing with solo drivers. The field is elite professional; it includes multiple drivers rated among the world's best, led by Alex Palou and Pato O'Ward, with Christian Lundgaard and Kyle Kirkwood among the next tier. Most drivers hold gold or platinum FIA grades reflecting experience at the sport's top levels. IndyCar sits above major feeder series, drawing drivers from Formula 3 Macau and Indy NXT while sending them to international sports car racing in IMSA WeatherTech and the WEC. It also receives drivers from Formula 1, where the calibre is stronger, and trades with International Formula 3000 at comparable strength.
