10 Amazing Facts About IndyCar

Indycars are open-wheel cars that participate in the famous 500-mile race known as the Indianapolis 500. The name was derived from the race, which is under the management of the Indy Racing League LLC. Here are some interesting facts that you should know about these cars:

1. Engine
The current generation of an Indycar is powered by a 2.2-liter twin turbo V-6 engine. This kind of an engine has a maximum bore diameter of 95 millimeters and produces an output of 550-750 horsepower, depending on the turbo boost used. It operates at a maximum RPM of 12,000. The turbocharging of the engine is enabled by the Twin BorgWarner turbochargers. It uses direct injection, which injects the fuel directly into the combustion chamber.

2. Engine Weight
The engine of an Indycar must have a minimum weight of 248 pounds. All the racing teams put all the required efforts to ensure that their cars don’t have an additional ounce to remain competitive in the race.

3. Number of Cylinders
The twin-turbo V6 engine of an Indycar has 6 cylinders. Each cylinder has 4 valves.

4. Gearbox
An Indycar has six forward gears and one reverse gear. The gearbox is supplied by Xtrac and uses a Mega-Line Assisted gear shift technology.

4. Fuel
One of the things that separate Indycars from other racing cars such as Formula One is the type of fuel used. Indycars are powered by methanol instead of gasoline. The main reason for using methanol is that it doesn’t explode.

5. Weight
An Indycar weighs approximately 1620Ibs on the streets and 1590lbs on the speedways. The figures do not include the weight of the driver and other accessories such as water bottles. The tires, engine and the chassis are included in this weight.

6. Wheels and Tires
The wheelbase of an Indycar is 121.5″. The front wheel is 15″ in diameter and 10″ wide. The rear wheel has a diameter of 15″ and a 14″ width. Indycars use Firestone Firehawk tires.

7. Construction
The chassis of an Indycar is made of carbon fiber, Kevlar, aluminum and other composite materials. The car’s monocoque is made of a cockpit, front suspension, and a fuel cell. The engine is integrated into the chassis. The rear side of the chassis consists of a gearbox, suspension components, and a bell housing.

8. Why Indycar racers drink milk
The tradition of drinking milk was introduced by the 2-time Indianapolis 500 winner Louis Meyer, who had a habit of refreshing himself with buttermilk after finishing a race. The practice which started in 1936 has become a tradition of this race.

9. Red Tires
There are two types of tires in the Indycar Series- “black tires” and “red tires.” Red tires are made of soft compounds but deliver instant and firmer grips than the black tires. However, they need to be handled with care because they tend to lose traction faster than the black tires. Red tires are rarely used.

10. Why Indycars are Dangerous
An Indycar is considered more dangerous than a Nascar. Apart from their high speeds, drivers sit in an open cockpit. In Nascar, the driver is protected by a cage. Indycars are also faster than the Nascars, mainly because they are lighter. A Nascar weighs 3200-3400 pounds while an Indycar weighs 1525 pounds.
