How Big Is An F1 Fuel Tank

how big is an f1 fuel tank

Formula One (F1) is the pinnacle of motorsports, where the world’s best drivers compete in the fastest cars on some of the world’s most challenging tracks. F1 cars are technological marvels, with every aspect of their design optimized for speed and performance. One critical aspect of an F1 car is its fuel tank size, which plays a vital role in race strategy and performance. In this article, we’ll explore how big an F1 fuel tank is, its history, regulations, design, capacity, and more.

F1 Fuel Tank Size Regulations

The Federation Internationale de l’Automobile (FIA), the governing body of F1, regulates the size of fuel tanks used in F1 cars. The current regulations stipulate that F1 cars must carry a maximum of 110 kilograms of fuel for a race. The size of the fuel tank is left to the teams to decide, as long as it does not exceed this limit. However, the regulations also state that the cars must have a fuel flow rate limit of 100 kg/hour, which ensures that teams cannot gain an unfair advantage by running higher fuel flow rates and, therefore, faster lap times.

Fuel tank size plays a crucial role in race strategy, especially for races that are long and require pit stops. The teams must calculate the optimum fuel load for each race, factoring in variables such as track conditions, tire wear, and weather. They must also account for the time lost during pit stops, where the car is refueled, and the driver’s tires are changed. Choosing the right fuel load is critical, as carrying too much fuel can slow down the car, while carrying too little fuel can result in the driver running out of fuel before the end of the race.

F1 Fuel Tank Size Throughout the Years

F1 fuel tank size regulations have changed over the years. In the early days of the sport, fuel tanks were much smaller, with cars carrying as little as 40 liters of fuel. However, as the sport evolved, fuel tank sizes increased to allow for longer races without refueling. In the early 2000s, F1 cars could carry up to 250 liters of fuel, which was enough to complete an entire race without stopping.

However, in 2010, FIA introduced regulations that mandated the use of smaller fuel tanks. The maximum fuel tank size was reduced to 150 liters, with teams required to use more fuel-efficient engines. This change was made to reduce the environmental impact of F1 and promote fuel efficiency.

The Design and Construction of F1 Fuel Tanks

F1 fuel tanks are designed to be as lightweight and durable as possible. They are usually made of carbon fiber, which is strong, lightweight, and can withstand high temperatures. The tanks are integrated into the car’s design, with the shape and size of the tank optimized for the car’s aerodynamics and weight distribution.

F1 fuel tanks are also subject to strict safety regulations to prevent fires or explosions. The tanks must be able to withstand significant impacts without rupturing, and they must be designed to minimize the risk of fuel leaks. F1 teams use various safety measures, such as foam inserts and fireproof coatings, to ensure that their fuel tanks are as safe as possible.

F1 Fuel Tank Capacity

F1 fuel tank capacity is calculated based on the maximum fuel load allowed for a race and the fuel efficiency of the engine. F1 engines are highly fuel-efficient, capable of using less fuel than a family car, despite being much more powerful. Fuel consumption during a race depends on several factors, including the track’s layout, the weather conditions, and the driver’s driving style.

F1 teams must optimize their fuel tank capacity for each race, balancing the need to carry enough fuel to complete the race while minimizing the weight of the car. Carrying extra fuel adds weight to the car, which slows it down and affects its handling. Therefore, teams aim to carry the minimum amount of fuel necessary to complete the race while factoring in possible safety car periods or unexpected events that could increase fuel consumption.


In conclusion, F1 fuel tank size is a critical aspect of F1 car design and race strategy. The current regulations allow for a maximum of 110 kilograms of fuel per race, with the fuel tank size left to the teams to decide. Fuel tank size has changed over the years, with current regulations mandating a smaller fuel tank size to promote fuel efficiency and reduce environmental impact.

F1 fuel tanks are designed to be as lightweight and durable as possible, made of carbon fiber and subject to strict safety regulations. F1 teams must optimize their fuel tank capacity for each race, balancing the need to carry enough fuel to complete the race while minimizing the weight of the car. In summary, F1 fuel tank size may seem like a small detail, but it plays a crucial role in F1 racing, impacting everything from race strategy to car design and safety.
