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.

The consumer-relevant engines, which are supplied by Chevrolet and Honda, utilize Speedway E85R fuel.
