What Engines Do Indy Cars Have?

Introduction

Indy cars are the pinnacle of open-wheel racing, and their engines are a major part of what makes them so fast and exciting. These engines are incredibly powerful and sophisticated, and they are constantly being developed to improve performance.

Engine Specifications

Indy car engines are all V6 turbocharged engines with a displacement of 2.2 liters. They are limited to a maximum of 12,000 RPM and must produce a minimum of 700 horsepower. The engines are also required to run on a specific blend of ethanol fuel.

Engine Manufacturers

There are currently two manufacturers that supply engines to the IndyCar Series: Chevrolet and Honda. Both manufacturers have a long history of success in the sport, and their engines are very competitive.

Chevrolet

Chevrolet has been supplying engines to the IndyCar Series since 1986. The company’s current engine is the IndyCar V6, which was introduced in 2012. The IndyCar V6 is a 2.2-liter, twin-turbocharged V6 engine that produces over 700 horsepower.

Honda

Honda has been supplying engines to the IndyCar Series since 1994. The company’s current engine is the Honda HR06E, which was introduced in 2017. The Honda HR06E is a 2.2-liter, twin-turbocharged V6 engine that produces over 700 horsepower.

Engine Development

The engines used in Indy cars are constantly being developed to improve performance. This development is often driven by new technologies that can make the engines more powerful and efficient.

One of the most significant developments in recent years has been the introduction of turbochargers. Turbochargers allow engines to produce more power without increasing their displacement. This has led to a significant increase in the horsepower of Indy car engines.

Another important development has been the introduction of direct injection. Direct injection allows fuel to be injected directly into the cylinders, which improves combustion efficiency and reduces emissions.

Conclusion

The engines used in Indy cars are some of the most powerful and sophisticated in the world. They are constantly being developed to improve performance, and they are a major part of what makes Indy car racing so exciting.
