Formula One (F1) cars are single-seat, open-cockpit, open-wheel racing cars that use a mixture of unleaded petrol and ethanol as fuel. F1 cars have been heavily regulated by the Fédération Internationale de l'Automobile (FIA) since 1996, with rules stipulating that the fuel must be of a similar standard to that used in road cars. The maximum amount of fuel an F1 car can use per race is 110 kilograms, although teams often fill the car with less fuel to reduce weight and improve performance. F1 cars do not have a traditional fuel tank; instead, they use a fuel sack or bladder made of high-quality rubber and lined with Kevlar, located behind the cockpit. The fuel is measured in weight rather than volume, as volume can change with temperature. F1 teams are committed to sustainability and are working towards a net-zero carbon target by 2030.

F1 fuel regulations
Formula 1 fuel has been heavily regulated by the FIA since 1996. The fuel used in F1 cars is a mixture of unleaded petrol and ethanol with a tightly controlled mixture ratio. The ethanol content was increased to 10% in 2022, up from 5.75%.
F1 cars use a fuel sack or bladder, similar to those used in military vehicles, made of high-quality rubber lined with Kevlar. This is located in front of the engine and behind the cockpit. The bladder is designed to maintain its structural integrity in crashes and be highly resistant to punctures.
F1 cars do not feature a fuel gauge as this would add unnecessary weight and not offer any useful accuracy. Instead, the bowser sits on load cells that measure the weight of the fuel very accurately. The tank is drained down regularly and an exact weight of fuel is pumped in as requested. The team will know how much fuel the car consumes in each mode at each circuit and fill it accordingly.
In terms of the amount of fuel used, F1 has been reducing the maximum fuel load over time. In 2013, 160kg of fuel was used in a race, which was reduced to 100kg by 2020. The fuel limit per race was increased to 105kg in 2017 and then to 110kg in 2019. F1 is aiming for each car to use just 70kg of fuel during a Grand Prix by 2026.
F1 cars must carry a maximum of 110kg of fuel per race, with at least 1kg left in the tank to be sampled by the FIA for post-race inspection. Abnormalities in the fuel or failure to provide the sample can result in disqualification from the race.

F1 fuel composition
Fuel is the sole source of power for a Formula One car and is, therefore, crucial for performance. F1 fuel comprises dozens of ingredients and is specially formulated for the engine it powers. The composition of the fuel is regulated by the FIA (Fédération Internationale de l’Automobile), which controls the formulation by limiting the hydrocarbon content that goes into the final product. The fuel must be very similar to the unleaded super at the pump and complies with strict restrictions.
The FIA's regulations have undergone considerable changes since their introduction in the late 1940s. Since the 2000s, several changes have been made aimed at sustainability and cost reduction, such as the cap on car parts, the usage of mixed fuel, and the usage of energy recovery systems. The basic structure and configuration of an F1 car have remained the same since the late 1960s, but the power output of the engines has increased progressively. In 1987-88, turbocharged eight-cylinder engines were introduced alongside atmospheric engines with fuel caps for races introduced for turbocharged engines. Turbochargers were banned from 1989 with 3.0-liter engines becoming the norm in the 1990s, leading to the introduction of V10 and V12 engines.
F1 cars use deformable fuel tanks made from puncture-proof Kevlar, which reshapes itself in the area where any pressure is being put. The fuel tanks are also lined with high-quality rubber for added protection against crashes. The size of the tank is important for chassis design and fuel consumption, expected average stint length, and aerodynamics. The tank is located under and behind the driver's seat, which determines the space between the driver and the engine.
In 2022, the FIA increased the ethanol content of F1 fuel from 5.75% to 10%, with plans to shift to 100% renewable fuel in 2026. This new generation of F1 cars will run on 'E10' fuel, a blend of 90% fuel and 10% renewable ethanol. F1's Chief Technical Officer, Pat Symonds, has spent months researching and developing this revolutionary fuel, which can be used not only in F1 cars but also in most road cars across the world.

F1 fuel optimisation
One of the key strategies for fuel optimisation in F1 is the use of energy-recovery techniques. The introduction of hybrid power units in 2014 played a significant role in improving fuel efficiency. These units recover energy that would typically be wasted, such as through the use of a novel turbocharger design. The turbocharger's turbine captures energy from the exhaust gas stream, and any extra energy is harvested to charge the car's battery or boost the drivetrain, resulting in increased power and reduced fuel consumption.
Another critical aspect of F1 fuel optimisation is the highly customised nature of the fuel blends. While commercial fuel and F1 fuel share similar compounds, each manufacturer optimises the fuel blend specifically for their team's engines. For example, Shell's fuel blend is tailored for Ferrari, and would not perform at the same level if used by another team. This optimisation process ensures that the fuel is finely tuned to extract peak performance from each team's unique engine design.
Furthermore, F1 regulations have played a pivotal role in driving fuel optimisation. Since 1996, the FIA has heavily regulated F1 fuel, mandating the use of Euro 95 standard fuel with compounds comparable to those found in road car petrol. The regulations have continued to evolve, with the 2022 season witnessing an increase in the bio-component ratio to 10%, aligning with the greener aims of mainstream carmakers.
In conclusion, F1 fuel optimisation is a complex and highly technical endeavour that involves innovative energy-recovery techniques, customised fuel blends, and stringent regulations. By focusing on fuel efficiency, F1 strives to not only enhance the sport's sustainability but also bridge the gap between racing technology and the advancements in road car development.

F1 fuel consumption
F1 cars use a mixture of unleaded petrol and ethanol, with the ratio being tightly controlled. The minimum octane rating for F1 fuel is 87, which is similar to the petrol used in road cars. Contrary to popular belief, F1 fuel is not a high-octane concoction vastly different from commercial fuel. The misconception may arise from the fact that F1 fuel is highly optimised for peak performance by each manufacturer, so the fuel mix varies between teams. For example, Shell's fuel is tailored for Ferrari, and would not perform optimally if used by Mercedes.
The fuel bladder, made of high-quality rubber lined with Kevlar, is located behind the cockpit for safety and performance reasons. It is designed to maintain its integrity during impacts and resist punctures. The bladder's deformable construction allows it to scrunch up within the chassis, contributing to the car's stability and weight distribution, which are critical factors in F1 racing.
To ensure cars do not run out of fuel during a race, engineers calculate fuel consumption per lap during winter testing, refining their estimates for each race based on car modifications and race conditions. While refuelling during races was previously allowed, it was banned by the FIA after the 2009 Brazilian Grand Prix incident involving Heikki Kovalainen and Kimi Raikkonen, prioritising the safety of drivers and pit crews.

F1 fuel sustainability
Formula One (F1) cars are single-seat, open-cockpit, open-wheel racing cars used for F1 racing events. They are constructed using carbon fibre and other composite materials to withstand high impact and G-forces. F1 cars have been at the forefront of innovation for over 70 years, with teams constantly pushing the boundaries of technology to gain a competitive edge.
The fuel used in F1 cars has been heavily regulated by the Fédération Internationale de l'Automobile (FIA) since 1996. Initially, the regulations stipulated that the fuel had to meet the Euro 95 standard, meaning it had to contain the same compounds as the petrol used in road cars. While the fuel used in F1 cars is a mixture of unleaded petrol and ethanol, it cannot contain any compounds not found in commercial pump fuel. However, the final product is highly optimised for peak performance by each manufacturer.
In recent years, there has been a growing focus on sustainability and reducing the environmental impact of F1 racing. F1 has set ambitious targets to achieve net-zero carbon emissions by 2030 and is working towards creating 100% sustainable fuels. The 2026 engine regulations will introduce 100% sustainable fuels, with no new fossil fuel carbon released during production. This shift towards sustainability is expected to have a significant impact beyond the race cars, potentially influencing the development of more sustainable road fuels.
F1 cars currently use E10 fuel, which contains 10% renewable ethanol. This ethanol is "green ethanol", meaning it is fully sustainable. The use of sustainable aviation fuel (SAF) is also being explored, with F1 investing in the purchase of SAF to reduce emissions in air travel and accelerate the adoption of more sustainable practices in the aviation industry.
To meet sustainability goals, F1 is also transitioning to renewable energy use at its offices and team facilities and implementing logistical changes, such as remote operations and increased sea freight, to reduce carbon emissions. Additionally, F1 teams have collaborated on projects like 'Project Pitlane' during the COVID-19 pandemic, where they contributed their technological expertise to ventilator production.
