Featuring racing at a combination of superspeedways, short ovals, road courses, and temporary street circuits, the NTT IndyCar Series offers its international lineup of drivers the most diverse challenges in motorsports. Founded in 1994, INDYCAR serves as the sanctioning body for the NTT IndyCar Series. These stars drive single-seat, open-cockpit cars that feature a 2.2-liter, twin-turbocharged, direct-injected V-6 engine optimized to run at 12,000 RPM with an estimated 500-700 horsepower depending on the turbocharger boost setting. The consumer-relevant engines, which are supplied by Chevrolet and Honda, utilize Speedway E85R fuel.
