Fuel tank capacity
The fuel tank capacity of NASCAR cars has been a topic of curiosity for fans and enthusiasts alike. While there have been various estimates and calculations, it is challenging to determine the exact fuel capacity of these cars due to several factors. Firstly, NASCAR rules allow teams to fill their cars with as much fuel as they want, and refuelling can occur during races. This flexibility in fuel loading makes it difficult to ascertain a precise fuel tank capacity.
That being said, it is estimated that the fuel cells in NASCAR cars hold approximately 18 US gallons. This estimate is specifically mentioned in relation to the Cup Series Next-Gen car. However, it's important to note that teams will often try to minimise the amount of fuel in the car at the start of a race to reduce weight and potentially gain a performance advantage.
The fuel consumption of NASCAR cars depends on various factors, including the length of the race, the number of caution laps, drafting, and individual driving techniques. For instance, during caution laps, cars run at a slower pace, resulting in reduced fuel consumption. Additionally, drafting allows drivers to maintain speed while using less throttle, which can lead to lower fuel consumption.
Estimates for fuel usage during races vary depending on the track and race length. For shorter tracks, a NASCAR car might use between 50 and 60 gallons of fuel. Intermediate tracks could see fuel consumption in the range of 70 to 80 gallons, while superspeedways might witness fuel usage of 80 to 90 gallons or more. These estimates are rough guidelines and can be influenced by various factors during a race.
NASCAR has also expressed interest in adopting regenerative braking and hybrid technology, which could further impact fuel tank capacity and consumption in the future. As NASCAR continues to evolve, it is likely that fuel strategies and tank capacities will remain a critical aspect of the sport, with teams constantly seeking ways to optimise performance and efficiency.

Fuel consumption
During a typical 500-mile race, a NASCAR stock car can burn approximately 100 gallons of fuel. However, this figure can vary depending on the track type and driving conditions. For shorter tracks, fuel consumption is estimated to be between 50 and 60 gallons, while intermediate tracks can see consumption ranging from 70 to 80 gallons. Superspeedways, such as Daytona, Talladega, and Atlanta, tend to have higher fuel consumption, with estimates ranging from 80 to 90 gallons.
The introduction of the seventh-generation NASCAR cars brought about significant changes in design and horsepower ratings, but the engines remained relatively unchanged. These cars are powered by 900HP V8 engines, utilising Sunoco Green E15 fuel, which contains 15% ethanol. The specialised fuel system required to burn this fuel contributes to the overall performance and efficiency of the vehicles.
NASCAR, like other motorsport series, is evolving with a growing focus on efficiency, clean energy, and sustainability. The organisation is planning to adopt regenerative braking and hybrid technology, demonstrating a commitment to reducing fuel consumption and environmental impact. This shift may challenge traditional NASCAR conventions but ultimately promises a more sustainable future for the sport.

Fuel type
NASCAR cars use fuel known as Sunoco Green E15, a fuel specifically used by various stock car racing series. Sunoco has been the official fuel of NASCAR for nearly two decades, since 2004. Sunoco Green E15 is a high-octane blend made exclusively for NASCAR by Sunoco. It has an ethanol content of 15% of the total volume of the fuel, requiring specialized fuel systems to burn the fuel due to increased levels of oxygen. The fuel is rated at RON98, which is the octane rating of the fuel, or how much the fuel can be compressed before it self-ignites.
Prior to the use of Sunoco Green E15, NASCAR cars used to run on leaded gasoline. NASCAR cars are known to use approximately 100 gallons of fuel in a typical 500-mile race, with a single NASCAR Cup Series car using approximately 125 gallons of Sunoco Green E15 during the 2015 Daytona 500 weekend. This figure does not include practice and qualifying sessions, accounting only for the complete distance of the 500-mile-long race. The 2015 Daytona 500, which saw 43 cars compete, used an estimated total of 5375 gallons of Sunoco Green E15.
The fuel efficiency of NASCAR cars is relatively low, with calculations showing that they get around 5 miles per gallon of fuel. This is in contrast to the average family SUV, which can achieve around 18 miles per gallon.
NASCAR fans and enthusiasts can purchase the Sunoco Green E15 race fuel in two sizes: a 5-gallon tank and a 55-gallon drum. Several race shops also sell the fuel by the gallon, with prices around $8.75.
