What You'll Learn
Indy cars use E85 fuel
E85 fuel offers a more environmentally friendly option for IndyCar racing, with the potential for increased sustainability in the sport. The use of ethanol-based fuel is a step towards more eco-conscious practices, and with the planned introduction of fully renewable fuel, IndyCar is taking further steps to reduce its environmental impact.
E85 is a unique fuel choice, and its use in IndyCar racing sets it apart from other motorsports. The decision to adopt E85 fuel likely involves careful consideration of the fuel's performance characteristics and how they align with the demands of IndyCar racing.
The low mpg of IndyCars means that efficient fuel usage is crucial. The average cost of E85 gas is $2.49, and during a race, the pit crew plays a vital role in refueling the car. The crew must work swiftly and efficiently to refuel the car, ensuring that the driver can get back on the track as quickly as possible.
The use of E85 fuel in IndyCar racing showcases the sport's commitment to both performance and environmental considerations. With the upcoming introduction of 100% renewable fuel, IndyCar continues to strive for sustainability without compromising the thrill and excitement of the race. This balance between speed and eco-friendliness is a unique challenge that IndyCar has embraced, pushing the boundaries of what is possible in motorsports.

E85 is an ethanol-based fuel
The percentage of ethanol in E85 may vary, typically ranging from 51% to 85%. This variation depends on the season, with lower levels of ethanol during colder months to produce the vapor pressure necessary for starting in cold temperatures. It also depends on the geographical location, with more ethanol added in warmer climates such as Brazil, where FFVs run on pure ethanol (E100).
E85 is a popular choice for motor racing clubs and sports car enthusiasts, especially in Australia. The motor racing industry often prefers ethanol- or methanol-based fuels as they give performance vehicles more thermal efficiency and increased torque. E85 can improve the engine's fuel consumption in advanced engines.
In the United States, the government has encouraged the production and sale of E85 through subsidies, particularly for corn producers in the Midwest. E85 costs less per gallon than regular gasoline, but vehicles using it generally travel fewer miles per gallon. However, proponents of higher ethanol-gasoline blends argue that ethanol-based fuel can be more efficient than gasoline. For example, an ethanol engine that can reach up to 22% more miles per gallon than a gasoline engine already exists.
It is important to note that E85 should not be used in vehicles not designed for flexible fuel, as it can cause damage. FFVs have sensors that detect the ethanol-gasoline ratio and make adjustments for optimal performance.

Ethanol is blended with 15% high-octane racing fuel
Indy cars use E85, an ethanol-based fuel. This fuel is a blend of ethanol and 15% high-octane racing fuel. This blend provides a high-performance fuel with a high octane rating, which is necessary for the powerful engines used in IndyCar racing.
Ethanol, also known as ethyl alcohol, is a renewable fuel source that can be produced from various plant materials, including corn, sugar cane, and cellulose. It is a clear, colourless liquid with a distinct smell, and it has a high octane number, which makes it suitable as a fuel for internal combustion engines. The high octane rating of ethanol helps to prevent engine knocking and improves the performance of the fuel.
When blended with 15% high-octane racing fuel, the ethanol-based fuel, E85, provides several benefits for IndyCar racing. Firstly, it offers a more complete combustion, which results in improved engine performance and increased horsepower. This is due to the higher compression ratios that can be achieved with E85, allowing for a more efficient burn and, consequently, increased power output.
Additionally, E85 is a renewable and environmentally friendly fuel option. The use of ethanol-based fuels can help reduce the dependence on fossil fuels and decrease the environmental impact of IndyCar racing. This is particularly significant given the high fuel consumption and low miles per gallon (mpg) of Indy cars. On average, an IndyCar achieves less than 2 mpg, which is extremely low compared to standard vehicles.
The introduction of E85 as the fuel for Indy cars is a positive step towards sustainability and environmental consciousness in motorsports. With the planned implementation of 100% renewable race fuel by Shell and IndyCar in 2023, the sport is taking further steps to reduce its carbon footprint and promote the use of eco-friendly alternatives.

IndyCar fuel tanks hold 18.5 gallons of gas
Indy cars made the switch from pure methanol to ethanol in 2007 to improve safety. The fuel formula is closely monitored by IndyCar officials, and each team draws its fuel from the same common fuel tank to ensure that no illegal additives are used. The fuel tanks are bolted to the ground to prevent teams from gaining an advantage by tipping the gravity-fed tanks.
IndyCar fuel tanks are made of rubber and are covered with a Kevlar-fitted blanket for additional protection against side impacts. The average cost of E85 gas is $2.49, and the mpg for IndyCars is less than 2. 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.
IndyCar fuel is closely monitored to ensure it has not been adulterated in any way. PerkinElmer, the official analytical instrumentation and fuel certification sponsor of IndyCar, has a Mobile Fuel Analysis Team that analyzes fuel at every race. They use the Clarus GC to test the fuel within 5 minutes, providing immediate findings to league officials.

IndyCar will introduce 100% renewable race fuel in 2023
IndyCar currently uses E85, an ethanol-based fuel blended with 15% high-octane racing fuel. However, in 2023, IndyCar will introduce a new fuel developed by Shell, becoming the first United States-based motorsports series to power its cars with 100% renewable race fuel. This fuel will be sourced from Raízen, a Brazilian joint venture between Shell and Cosan, which is one of the largest sugarcane ethanol producers in the world.
The new fuel is second-generation ethanol, an upgrade from the first-generation ethanol previously used. Second-generation ethanol is produced from waste feedstock rather than competing with the food chain. This means that it can be sourced from waste rather than corn or sugar, which are used for food and livestock feed. The use of this renewable fuel will enable a significant reduction in greenhouse gas emissions, with at least a 60% decrease compared to fossil-based gasoline.
The introduction of 100% renewable race fuel is a significant step towards sustainability in motorsports. IndyCar and the Indianapolis Motor Speedway have already made strides in this direction, such as using fully electric Penske Truck Leasing trucks to deliver Firestone Tires for the Indianapolis 500. The adoption of renewable fuel for the races themselves is a further commitment to reducing the carbon footprint of the sport.
The new fuel has been met with enthusiasm by those involved, with dyno-tests described as "terrific" and expectations that the fuel will perform well on the track. The switch to renewable fuel is also expected to have a positive impact beyond motorsports, with the potential for the fuel to be adopted in the automotive marketplace and contribute to reducing carbon emissions on a larger scale.
This initiative by IndyCar and Shell showcases how sustainability and performance can go hand in hand. By utilising food waste and waste feedstock to produce renewable fuel, IndyCar is not only reducing its environmental impact but also highlighting the potential for innovative and sustainable solutions in the racing industry and beyond. It will be exciting to see the continued advancements and adoption of renewable fuels in the future.
