What is the difference between Formula 1 and Indy cars? The difference between F1 and Indy in terms of the engine is that F1 uses a 1.6-liter V-6 whereas the Indy car comes with a 2.2-liter V-6.
The term "Indy Car" began as a nickname for the cars that competed in USAC's "Championship" division of open-wheel auto racing in the United States, deriving from the sport's most popular competition, the Indianapolis 500.
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.
