The Indy 500 is one of the greatest car races in the world, showcasing innovative engineering and sleek car designs. The race is held annually on Memorial Day weekend on a 2.5-mile oval track known as The Brickyard. The Indy cars are known for their speed and power, with engines that produce between 550 and 700 horsepower, capable of accelerating from 0 to 100 mph in about 3 seconds. With such high-performance engines, it is important to understand the fuel requirements and capacity of these cars. So, how much fuel does an Indy 500 car hold, and what type of fuel do they use?

What You'll Learn
IndyCars use E85, an ethanol-based fuel blend
The Indy 500 is an annual race where sleek cars compete to be the first to complete 200 laps of the famous oval at speeds of up to 240 mph. Each car in the race will consume about 0.6 gallons of fuel per lap, or 125 gallons if they complete the race.
IndyCars use an 85% ethanol fuel blend, or E85. This has been the case since 2018, when the blend was changed from 98% ethanol. Before that, methanol was used as fuel. The switch to ethanol was made for several reasons, including safety and fuel economy. Ethanol is much safer than methanol, and it gives better mileage. It is also a popular fuel worldwide due to its fuel economy and renewability—it can be made from crops like corn, making it a more environmentally friendly option than gasoline.
The Indy Racing League first used ethanol in 2006, and in 2007, the IndyCar series shifted from natural gas-based methanol to pure corn ethanol. The adoption of E85 ethanol has worked better for IndyCar than the fuel gambles of other race series, and it has kept costs stable. Despite being 25% less efficient than gas, E85 can be used in familiar V-6 racing engines with some technical tweaks.
The fuel blend also has good PR value for IndyCar, allowing the series to answer critics who decry auto racing as a waste of fuel. The Indy 500 takes place in the Midwest farm belt, so the use of corn ethanol as a fuel makes sense for the race.

Indy 500 cars consume 0.6 gallons per lap
The Indy 500 is one of the greatest car races in the world, showcasing innovative engineering and the skill, stamina, teamwork, and guts of drivers. The race is held on a 2.5-mile oval track known as The Brickyard, and each car must complete 200 laps to finish the race.
Indy 500 cars consume 0.6 gallons of fuel per lap. This works out to an average of 4 miles per gallon, with an average mpg of less than 2, which is considered crazy low. The fuel used is E85, an ethanol-based blend with 15% high-octane racing fuel.
The low mpg of Indy 500 cars is due to their powerful engines, which produce between 550 and 700 horsepower, allowing them to accelerate to 100 mph in about 3 seconds. The cars can reach top speeds of over 230 mph on the straights.
To ensure fair competition, all team fuel tanks are bolted to the ground and filled before the race. The fuel is carefully analysed by the Mobile Fuel Analysis Team to ensure it has not been adulterated in any way, as modifying the fuel is against race regulations.

Fuel tanks are bolted to the ground
The Indy 500 is one of the greatest car races in the world, showcasing innovative engineering and the skill, stamina, teamwork, and guts of drivers. The race takes place on a 2.5-mile oval track known as The Brickyard, and cars can reach speeds of up to 240 mph.
IndyCars use E85, an ethanol-based fuel blended with 15% high-octane racing fuel. The fuel cells for these cars have a capacity of 18.5 gallons (70 litres), though this has changed over the years, with capacities of 22 gallons (2007-2011), 30 gallons (2004-2006), and 35 gallons (1997-2003) in the past.
The fuel tanks for the Indy 500 are bolted to the ground to ensure fairness and prevent any team from gaining an advantage by tipping the gravity-fed tanks. This is just one of the ways in which the race organisers ensure that the focus is on the drivers and their skills rather than the cars or fuel.
To prevent teams from modifying the fuel, PerkinElmer's Mobile Fuel Analysis Team analyses fuel samples from up to 20 cars per event using a mobile lab set up in the back of an INDYCAR semi-tractor trailer. This is the only company that provides findings to league officials right on the track, allowing them to take immediate action if necessary.
With such high speeds and performance, the Indy 500 cars consume a significant amount of fuel. On average, these cars get less than 2 miles per gallon, and during the race, they can consume about 0.6 gallons per lap or 125 gallons if they complete the race.

Indy 500 fuel cells have a capacity of 18.5 gallons
The Indy 500 is one of the greatest car races in the world, showcasing innovative engineering and the skill, stamina, teamwork, and guts of drivers. The fuel used in these racing cars is just as important as horsepower and performance.
IndyCars use E85, an ethanol-based fuel blended with 15% high-octane racing fuel. The average cost of E85 gas is $2.49. The mpg (miles per gallon) for IndyCars is less than 2, which is considered low. It takes the pit crew an average of 7 seconds to refuel at each stop, and the driver an average of 40 seconds to complete each lap.
The Indy 500 cars are sleek and fast, accelerating to 100 mph in about 3 seconds. Chevrolet and Honda are the current suppliers of racing engines, with 2.2-liter twin-turbocharged, direct-injected V6 engines that run at 12,000 rpm during the race. The cars are also designed with aerodynamics in mind, with right-side tires that are larger in diameter to help push the car to the left in the turns.

Indy 500 cars average under 2 mpg
The Indy 500 is an annual race held every Memorial Day weekend on a 2.5-mile oval track known as The Brickyard. It features 33 of the world's fastest cars, reaching speeds of up to 240 mph. The Indy 500 cars have 700 horsepower and accelerate to 100 mph in about 3 seconds.
These cars use E85, an ethanol-based fuel blended with 15% high-octane racing fuel. The fuel is optimized for performance, and the cars average under 2 mpg (miles per gallon). In 1987, the engines with around 720 HP had a maximum mpg of 1.8, and in 2011, the average mpg was 1.92.
The low mpg of the Indy 500 cars results in a high fuel consumption rate. Each car can consume about 0.6 gallons per lap or 125 gallons if they complete the 200-lap race. The fuel tanks of the IndyCars can hold 18.5 gallons of gas, and it takes the pit crew around 7 seconds to refuel at each stop.
The high fuel consumption and frequent refueling stops are a trade-off for the incredible speed and performance of these racing cars. The Indy 500 is a showcase of both driving skill and the importance of fuel strategy in racing.
