NASCAR cars burn a lot of fuel, and the sport has historically been criticised for its negative environmental impact. However, NASCAR has been taking steps to reduce its carbon footprint, including tree-planting initiatives and the use of more environmentally-friendly fuels. The amount of fuel used by NASCAR cars varies depending on the race and the team's fuel management strategy, but the fuel tanks typically hold around 18 US gallons, and cars average around 4-5 miles per gallon.

What You'll Learn
NASCAR fuel usage and environmental concerns
NASCAR fuel usage has been a topic of discussion for many years, with concerns about the environmental impact of the sport. During a typical NASCAR race weekend, with over 40 cars running at high speeds for 500 miles (804 kilometres) and completing practice laps, the fuel usage can reach approximately 6,000 gallons (22,712 litres). This equates to about 120,000 pounds (54,431 kilograms) of carbon dioxide emissions for the race weekend. With around 35 races per year, NASCAR's annual carbon footprint can reach up to 4 million pounds (1.8 million kilograms) of CO2.
NASCAR cars have non-EPA-regulated engines, which, combined with their high speeds, contribute to the sport's significant fuel consumption and environmental impact. The standard fuel efficiency for a NASCAR car is 5 miles per gallon, far lower than the average commuter car, which can achieve 20 to 50 miles per gallon.
In the past, NASCAR has been criticised for its use of leaded gas, which releases toxic lead into the atmosphere. However, more recently, NASCAR has taken steps towards reducing its environmental footprint. For example, NASCAR has partnered with the U.S. Environmental Protection Agency to promote high-MPG vehicles at NASCAR races, encouraging fans to consider more fuel-efficient options for their daily commutes. Additionally, NASCAR teams are making efforts to offset their carbon emissions, such as purchasing carbon credits or buying acres of rainforest to compensate for their carbon footprint.
NASCAR is also planning to adopt regenerative braking, a move towards hybrid technology, although this may be met with resistance from traditional fans. Despite these initiatives, some critics argue that NASCAR needs to implement more significant technological changes to reduce its environmental impact.

NASCAR fuel tank capacity
In a single typical NASCAR race weekend, with more than 40 cars at high speeds for 500 miles (804 kilometres) — plus practice laps — at 5 mpg of gas, the cars will use about 6,000 gallons (22,712 litres) of fuel. The 2015 Daytona 500, for example, saw 43 cars use an estimated 5,375 gallons of racing fuel.
NASCAR has been labelled as wasteful and one of the least environmentally friendly sports due to its fuel usage and dangerously high speeds. In the 1970s, during a fuel shortage, NASCAR temporarily shortened one of its races from 500 miles to 450 miles as a goodwill gesture. However, NASCAR has said it plans to plant enough trees near its racetracks to offset carbon emissions for the next 40 years. The organisation is also planning to adopt regenerative braking in the near future, a move towards hybrid technology.

NASCAR's transition to unleaded fuel
NASCAR had long been criticised for its high fuel consumption and negative impact on the environment. The sport was labelled a "waste of gas" during the fuel shortage of the 1970s, and the US government exempted it from the 1970 Clean Air Act, which banned leaded fuel in automobiles. Despite attempts to test unleaded fuel in 1998, it was found to contain additives dangerous to groundwater.
In 2006, NASCAR announced its plan to transition to unleaded fuel, with a tentative timetable to implement the change by 2007 or 2008. The organisation faced pressure from environmental groups and researchers who studied the effects of lead exposure on communities near racetracks. A single NASCAR race emitted more than 10 kilograms of lead, impacting the health and academic performance of children living near racetracks.
The switch to unleaded fuel occurred in 2007, and the positive impacts were soon evident. Researchers found that children living near racetracks began performing better in school, with substantial increases in test scores. The use of unleaded fuel also reduced mortality rates in surrounding counties and improved birth weights for babies born to mothers living in those areas.

NASCAR's use of ethanol fuel blends
NASCAR has long been associated with powerful, gas-guzzling sports cars that burn a lot of fuel. In a typical NASCAR race weekend, with over 40 cars racing at high speeds for 500 miles, the cars consume about 6,000 gallons of fuel. This amounts to a carbon footprint of around 4 million pounds of CO2 annually.
However, NASCAR has taken steps towards reducing its environmental impact by adopting ethanol fuel blends. In 2011, NASCAR transitioned from using leaded fuel to Sunoco Green E15, a fuel blend containing 15% ethanol. This change resulted in a 20% reduction in emissions, equivalent to taking 124 million cars off the road. The use of ethanol blends is part of NASCAR's "Race to Green" initiative, showcasing its commitment to environmental sustainability.
The switch to ethanol blends has also improved engine performance. American Ethanol, a partner of NASCAR, promotes the benefits of ethanol as a clean-burning, renewable energy source. The ethanol used in NASCAR is derived from American corn, which is converted into a biofuel through a refining process involving enzymes. This biofuel is then blended with Sunoco Racing fuel, resulting in a high-performance product.
While the adoption of ethanol blends has been praised for its environmental benefits, some critics argue that ethanol is less efficient than gasoline, requiring more frequent refuelling stops. Nevertheless, NASCAR's decision to embrace ethanol blends has contributed to a wider trend in the United States, with the ethanol industry advocating for its broader acceptance.

Fuel management strategies in NASCAR
NASCAR racing is a fuel-intensive sport, with teams allowed to fill up with as much fuel as they want during races. The fuel cells in NASCAR cars typically hold around 18 US gallons, but teams will try to put in as little as possible to keep the car light and quick. The amount of fuel used in a race can range from tens to hundreds of gallons, and fuel management is a critical aspect of the sport.
One key strategy is to reduce the time spent idle during pit stops. Teams calculate the exact fuel needed to avoid carrying extra weight, and crew members train to connect and disconnect fuel lines swiftly and safely. Coordinating fueling with tire changes is crucial, and NASCAR teams use state-of-the-art fueling systems to minimize spillage and speed up refueling.
Aerodynamics also play a significant role in fuel efficiency. NASCAR teams focus on refining aerodynamics and engine tuning to optimize fuel economy and gain a competitive edge. Additionally, regenerative braking and hybrid technology are being introduced to enhance efficiency and performance, representing a greener future for the sport.
The adoption of hybrid systems combines traditional high-performance engines with electric power, improving acceleration and top speeds while providing research and development opportunities for the automotive industry. These advancements align with the global trend toward greener technologies and address concerns about NASCAR's environmental impact.
