The fuel tank is a critical component of any racing car, and Formula 1 cars are no exception. Historically, F1 fuel tanks were metal and prone to rupturing during accidents, leading to dangerous fuel spills and fires. However, since 1970, F1 cars have used flexible fuel tanks or bladders made of military-grade ballistic material to prevent these issues. These bladders are located in the centre of the car, between the driver and the engine, and hold approximately 160kg or 230 litres of fuel, enough to last the entire race. This innovative design and positioning of the fuel tank in F1 cars ensure safety and optimal performance on the track.

The fuel tank is a bladder made of military-grade ballistic material Kevlar, reinforced with rubber
The fuel tank in a Formula 1 car is located behind the driver's seat and directly ahead of the engine. The position of the tank is unconventional, to say the least. Sitting right between the engine and the driver, the fuel tank is one of the most indestructible objects in an F1 car. The tank is encased within a crushable structure that forms part of the car's safety cell. This structure must be able to withstand very high-impact loads as specified in the regulations.
Kevlar is used in a variety of applications, including bulletproof vests, combat helmets, armoured vehicles, aircraft, bomb blankets, and as protection from bullets for SWAT and military personnel. It is also used by firefighters for its high heat resistance. Kevlar is an effective material for residential safe rooms, providing protection from bullets, fire, storms, and acoustic insulation.
In the context of Formula 1 fuel tanks, the use of Kevlar, reinforced with rubber, creates a puncture-proof bladder that meets the FT5 fuel tank standard set by the FIA (Fédération Internationale de l'Automobile). The bladder construction is complex, involving numerous internal baffles and fuel collection chambers. The fuel system utilises lift pumps positioned in the corners to suck up fuel and regulate pressure.
The use of Kevlar in the fuel tank bladder ensures that the tank is practically indestructible, even in the event of a high-impact accident. This level of safety is crucial, as fuel-related fires and accidents have historically been a significant concern in Formula 1 racing.

It is located between the engine and the driver
The fuel tank in a Formula 1 car is located between the engine and the driver. This positioning is highly strategic. The fuel tank is one of the largest components of an F1 car, yet it only accounts for about 1% of the vehicle's total weight. The tank is designed to hold almost 160 kg of fuel, or 230 litres, and is placed directly behind the driver's seat. This positioning is a safety measure, as it ensures that the driver is protected from the engine's heat and any potential fuel leaks.
The fuel tank is also placed in this location to optimise the car's aerodynamics. The further back the driver and the side pods are, the cleaner the air will be onto the side pods. This positioning also allows teams to place the fuel tank as close to the ground as possible, which improves the car's aerodynamics and stability.
The fuel tank in an F1 car is not a conventional box-shaped tank. Instead, it is a flexible bladder made of military-grade ballistic material Kevlar, reinforced with rubber. This design was introduced in 2010 to prevent fuel leaks and improve safety. The bladder is puncture-proof and virtually indestructible, even in the event of an accident.
The fuel system in an F1 car is highly sophisticated and designed to recover fuel from the tank and regulate pressure. It features a network of low-pressure electrically powered "lift pumps" positioned in the corners of the tank to suck up the fuel. The lift pumps deliver the fuel to a smaller vessel known as a "collector", which then delivers the fuel to a mechanically driven fuel pump that supplies the injectors. This system ensures a constant fuel supply to the engine, even during acceleration, cornering, and braking when the fuel sloshes around the tank.

The fuel system uses lift pumps to suck up fuel from tank corners
The fuel tank in a Formula 1 car is located behind the driver's seat and directly ahead of the engine. The position of the tank is crucial for aerodynamic purposes, and it largely determines the space between the driver and the engine. The tank is designed to be as small as possible while holding the required amount of fuel for the race.
The fuel system in a Formula 1 car is a critical component that ensures the efficient delivery of fuel from the tank to the engine. This system utilizes lift pumps, also known as transfer pumps, which are typically low-pressure, electrically powered pumps. These lift pumps are strategically positioned within the fuel system to suck up fuel from the tank corners.
In a Formula 1 car, there are usually three or four lift pumps employed to ensure effective fuel recovery. These pumps play a vital role in transferring fuel from the tank corners to the injection pump or the rest of the fuel system. By operating at low pressure, the lift pumps ensure a steady and controlled flow of fuel without causing excessive pressure variations within the tank.
The use of lift pumps in the fuel system offers several advantages. Firstly, they enable the efficient utilization of fuel, ensuring that every last drop from the tank corners is drawn out. This is particularly important in Formula 1 racing, where the amount of fuel loaded into the car can significantly impact lap times due to the added weight.
Additionally, the lift pumps contribute to the safety of the vehicle. By regulating fuel pressure and controlling the flow, the risk of fuel spillage or leakage during accidents is reduced. This is a significant improvement over the historical design of metal fuel tanks, which were more susceptible to rupturing and causing fires in the event of a crash.
In summary, the fuel system in a Formula 1 car, including the use of lift pumps to suck up fuel from tank corners, showcases the intricate engineering and attention to detail that goes into these high-performance vehicles. The system's design not only ensures efficient fuel delivery but also contributes to the overall safety and performance of the car.

The bladder is flexible and placed inside the monocoque of the car
The fuel tank in a Formula 1 car is located within the monocoque, behind the driver's seat, and in front of the engine. The tank is carefully placed between the driver and the engine, determining the space between them. The position of the tank is unconventional and carefully designed. The bladder is flexible and placed inside the monocoque of the car, well protected within a box made of several layers of composite material. The bladder is hand-made and assumes a funny shape to fit the profile of the monocoque. Several exotic materials are used in the fabrication of the bladders, with a single bladder costing about $30,000 to make.
The bladder is a single puncture-proof structure made of military-grade ballistic material Kevlar, reinforced with rubber. It is practically indestructible and is one of the most indestructible objects in an F1 car. The bladder is designed to be flexible and is placed inside the monocoque to prevent ruptures, fuel spillage, and fires in the event of accidents. The flexible nature of the bladder also helps control fuel slosh and contains the fuel pumps, with internal venting to ensure the fuel fills and drains the tank without causing pressure variations.
The fuel tank in a Formula 1 car is subject to various regulations and standards. It must be manufactured by specific FIA-approved companies and meet the FT5 fuel tank standard. The bladder is designed to hold approximately 160 kg or 230 litres of fuel, with a maximum weight of fuel mandated. The size of the tank is carefully considered during chassis design, taking into account fuel consumption, expected race length, and aerodynamics. The fuel system in a Formula 1 car is designed with multiple low-pressure electrically powered "lift pumps" positioned to suck up fuel from the tank corners. The lift pumps deliver fuel to a smaller vessel within the fuel cell, known as a "collector", which pressurises the fuel and feeds it to the main pump.
The fuel tank in a Formula 1 car is a critical component, ensuring the car has enough fuel to complete the race without refuelling. The flexible bladder design, placed within the monocoque, provides safety, fuel efficiency, and performance advantages. The careful placement of the bladder inside the monocoque showcases the intricate design and engineering that go into Formula 1 cars.
