What You'll Learn
F1 fuel tanks carry up to 110kg of fuel
The amount of fuel an F1 car uses is measured in kilograms because fuel volume changes with temperature, whereas mass does not. The fuel tanks are made from Kevlar and polyurethane, making them almost indestructible. This means that in the event of a crash, fuel should not leak, reducing the risk of fire.
F1 fuel is heavily regulated and must be 'petrol as this term is generally understood'. It currently uses E10 fuel, consisting of 90% gasoline and 10% renewable ethanol. The ethanol content was increased from 5.75% in 2022, as part of the sport's push towards sustainability and net-zero emissions by 2030. F1 fuel must be formulated from compounds found in commercial fuels and cannot contain any chemical compounds that boost power.
The cost of fuelling an F1 car is likely to far exceed the cost of fuelling a regular road car, which is around £180 to £200. This is due to the refinement of the fuel used and the technology required to deliver it.

F1 fuel costs likely exceed £180-£200
F1 fuel costs are likely to exceed the £180-£200 range for filling up a regular road car. This is due to the highly refined nature of F1 fuel and the advanced technology required to produce it.
F1 fuel is subject to strict regulations and must be formulated from compounds found in commercial fuels, without any power-boosting chemical additives. The fuel is a mixture of unleaded petrol and ethanol, with the latter's content recently increased from 5.75% to 10% in 2022, constituting E10 fuel. This fuel has a minimum octane rating of 87, contrary to the common misconception that it is a high-octane concoction.
F1 cars can carry a maximum of 110 kilograms of fuel per race, but the actual amount used depends on various factors, including ambient temperature, car weight, and circuit design. The fuel is measured in weight rather than volume because volume can change with temperature, whereas mass remains constant.
The cost of the fuel itself is only one aspect of F1 fuel expenses. The fuel tanks in F1 cars, made from Kevlar and polyurethane, are reported to cost around £22,000 ($30,000). Additionally, the engines and other components contribute significantly to the overall cost of the car's performance.
F1 has been undergoing a significant transformation towards sustainability and cost reduction. The introduction of hybrid technology, energy recovery systems, and the push for net zero by 2030 are all part of this shift. While the exact fuel costs for F1 cars are not publicly available, it is evident that the expenses associated with their fuel go beyond the mere price of the fuel itself.

F1 fuel tanks cost £22,000
F1 fuel tanks are described as 'almost indestructible' and are made from Kevlar and polyurethane. The fuel bladder is made of high-quality rubber lined with Kevlar for protection against crashes and is located in front of the engine, behind the cockpit. In the event of a crash, fuel should not leak, and the threat of a fire is limited. These safety measures are important, given the history of crashes and fires during pit stops. In 1994, Jos Verstappen's car and the driver himself caught fire during a pit stop at the German Grand Prix. Fortunately, the driver was pulled from the car, and the fire was extinguished, but Verstappen and four mechanics suffered minor burns.
F1 fuel tanks cost a reported £22,000 ($30,000). This is a significant expense, but one that is justified by the safety benefits of the tanks. The way in which the fuel tank is scrunched up and pushed into the chassis makes it look like a basic piece of kit, but in reality, there is a lot of advanced technology involved. The tank has a series of internal baffles fitted with one-way valves that compartmentalise the fuel and channel it down to the lowest rearward compartment. This ensures that the car remains stable and that fuel can be transferred effectively by scavenger pumps when the car is running low on fuel.
The cost of the fuel itself is also higher than that of regular petrol. While it is true that F1 fuel is derived from compounds found in commercial fuels, it also undergoes a high level of refinement and is formulated to be more fuel-efficient and environmentally friendly. The exact cost of refuelling an F1 tank is confidential, but it is estimated to be far higher than the £180 to £200 it would cost to fill a regular road car with petrol.
F1 cars can carry up to 110 kilograms of fuel per race, but teams rarely fill the tanks to capacity. This is because a heavier car loses lap time, and drivers can compensate for having less fuel by using techniques such as lift and coast. The volume of fuel in an F1 tank can vary between 130 and 145 litres, depending on temperature, as volume changes with temperature, whereas mass does not.

F1 fuel is 90% gasoline, 10% ethanol
F1 fuel has undergone a series of changes over the years, with a focus on sustainability and performance. In 2022, new fuel regulations were introduced, mandating a blend of 90% gasoline and 10% ethanol, known as E10 fuel. This change was part of F1's commitment to environmental sustainability and marked a shift towards renewable fuels.
E10 fuel in F1, consisting of 90% gasoline and 10% ethanol, was introduced to align with the trending fuel changes in the automotive industry. E10 fuel is now widely used in gas stations across the US, Europe, and the UK. This new blend aimed to strike a balance between high performance and environmental considerations.
The 10% ethanol content in E10 fuel brings several advantages to F1 engines. Firstly, ethanol has favourable evaporation characteristics, allowing it to extract temperature from the combustion chamber during the initial stages of combustion. This enables mapping engineers to optimise ignition timing, resulting in better-timed combustion. Additionally, the higher ethanol content provides engineers with more configuration flexibility, enhancing the efficiency potential of F1 engines.
However, the introduction of E10 fuel presented new challenges for F1 teams. Ethanol has a lower energy density than regular gasoline, leading to increased fuel consumption. To compensate, teams had to add more fuel to their cars to ensure they could complete the race distance. Additionally, E10 fuel is heavier than its predecessor, E5 fuel, requiring adjustments in engine design to account for the extra weight.
F1 fuel tanks can carry up to 110 kilograms of fuel, and the cost of refining the fuel and the technology involved likely exceeds the cost of fuelling a regular road car. F1's goal is to achieve 100% sustainable fuels by 2026 and Net Zero Carbon status by 2030, demonstrating its commitment to environmental sustainability and performance innovation.

F1 fuel efficiency is over 50%
F1 fuel efficiency has been a growing area of focus in recent years. The 2020 Mercedes engine, for example, achieved over 50% thermal efficiency, marking a significant improvement from the roughly 44% efficiency of 2014 engines. This means that over half of the energy in the fuel is used to propel the car forward, compared to around 30% for a typical road car.
F1 cars are allowed a maximum of 110 kilograms of fuel per race (approximately 190 miles), but they don't always use the full allocation. This is because more fuel means a heavier car, which costs time on the track. The use of hybrid technology in F1 cars has been instrumental in improving fuel efficiency, with the sport introducing a new generation of power units in 2014 that combine a traditional internal combustion engine (ICE) with an energy recovery system (ERS). The ERS includes two motor generator units - kinetic (MGU-K) and heat (MGU-H) - which recover waste energy from braking and heat, respectively.
The MGU-H, in particular, has been crucial in improving thermal efficiency. By attaching a generator-like device to the turbocharger shaft, waste heat in the exhaust gas is transformed into rotational energy to recharge the battery, which then powers the MGU-K electric motor/generator. This system, along with other innovations like pre-chamber combustion, has allowed F1 engines to achieve impressive power outputs while also improving fuel efficiency.
The push for greater fuel efficiency in F1 is driven by a desire for sustainability and road relevancy. F1 fuel has become increasingly regulated, with a focus on using compounds found in commercial fuels and eliminating chemical compounds that boost power. The sport aims to develop 100% sustainable fuel by 2030 and achieve net-zero status, demonstrating its commitment to environmental responsibility.
While the exact cost of F1 fuel is not publicly available, it is likely to far exceed the cost of fuelling a regular road car due to the refinement of the fuel and the technology required. F1 fuel tanks, for example, are made from Kevlar and polyurethane, contributing to their high cost of £22,000 ($30,000).
