Engine Development
The engines used in Indy cars have evolved significantly over the years. In the early days of the sport, naturally aspirated engines were the norm. However, in the late 1970s, turbocharged engines began to be introduced. Turbochargers allow engines to produce more power by increasing the amount of air that is forced into the cylinders.
The first turbocharged Indy car engine was developed by Cosworth in 1976. This engine was used by Mario Andretti to win the Indianapolis 500 in 1977. Turbocharged engines quickly became the standard in Indy cars, and they have been used ever since.
In recent years, the engines used in Indy cars have become even more powerful. In 2012, the NTT IndyCar Series introduced a new engine formula that allowed for engines to produce up to 700 horsepower. This new formula has resulted in even faster and more exciting racing.
Engine Manufacturers
There are currently two engine manufacturers that supply engines to the NTT IndyCar Series: Chevrolet and Honda. Chevrolet has been involved in Indy car racing since the early days of the sport, and they have won more Indianapolis 500s than any other engine manufacturer. Honda entered the NTT IndyCar Series in 2012, and they have quickly become one of the top engine manufacturers in the sport.
Both Chevrolet and Honda have developed very competitive engines for the NTT IndyCar Series. The engines are extremely powerful and reliable, and they allow the drivers to push their cars to the limit.
Conclusion
The engines used in Indy cars are some of the most powerful and advanced racing engines in the world. They are capable of producing up to 700 horsepower and they allow the drivers to achieve speeds of over 200 mph.
