IndyCar Series (Johnsonverse)

The IndyCar Series, currently known as the NTT IndyCar Series under sponsorship, is the premier level of open-wheel racing in North America. Its parent company began in 1996 as the Indy Racing League (IRL), which was created by then Indianapolis Motor Speedway owner Tony George as a competitor to CART. In 2008, the IndyCar Series merged with CART's successor, the Champ Car World Series. The series is self-sanctioned by its parent company, INDYCAR, LLC., which is owned by Johnson Industries.

The series' premier event is the Indianapolis 500.
