Weight plays a crucial role in Formula 1, where every gram counts. Over the years, F1 cars have been gradually getting heavier, primarily due to the implementation of enhanced safety features. In this article, we will explore the weight specifications of an F1 car, including the minimum weight, driver weight, and the weight of various car components.
The Weight of an F1 Car
As of 2023, the minimum weight requirement for an F1 car is 798kg (1,759 lbs). Initially set at 795kg, the limit was increased by 3 kilograms as teams struggled to meet it. The FIA, the governing body of F1, sets this minimum weight in its rulebook.
However, teams often need more than the minimum weight due to varying factors such as different car designs and components. Each team strives to approach the lower limit as closely as possible to maximize performance.
Driver Weight
An F1 driver must weigh at least 80kg according to FIA regulations. However, since most drivers weigh less than 80kg, ballast is added to the cockpit to compensate for the difference. This ballast helps achieve the desired weight distribution for optimal balance and handling. The driver's weight includes their helmet, race suit, and shoes.
After each race, drivers are weighed for two primary reasons:
- Firstly, it allows teams to monitor the weight lost during the race, helping them determine the necessary replenishment of fluids and adjust training programs.
- Secondly, since the car's minimum weight includes the driver, their weight needs to be known to ensure compliance with the minimum weight limit.
Weight of F1 Parts
While the overall weight of an F1 car must not be less than 798kg, individual components have their weight specifications. Being the heaviest part, the engine must weigh a minimum of 150kg, while the steering wheel is one of the lightest components, weighing around 1.3kg. Some features have specific weight requirements listed in the rulebook, while others can be made as light as possible by the teams.
Evolution of F1 Weight
Over the years, F1 cars have experienced significant changes in weight due to various factors. In 2022, the cars reached their heaviest point in F1 history at 798kg, mainly due to the inclusion of safety features like the halo and the banning of refueling. In previous years they witnessed fluctuations in weight due to the introduction of hybrid engines, wider wheels and tires, and other technological advancements.

Weight is critical in Formula 1, with teams striving to optimize the balance between performance and safety. Each car component contributes to the overall weight, with the engine being the heaviest and the steering wheel being one of the lightest. As the sport evolves, weight will remain critical in pursuing speed and success on the race track.
Why do F1 drivers weigh themselves before and after a race?
F1 drivers weigh themselves before and after a race for two main reasons:
Firstly, it helps measure the weight the driver lost during the race. Factors like intense physical exertion and hot conditions can cause drivers to lose around 2-3kg (4-6lb) or even more in extreme cases. By understanding the extent of weight loss, the team can replenish fluids and adjust training programs accordingly for the following week.
Secondly, the weight of the driver is a crucial component in meeting the minimum weight limit of the Formula 1 car. As the minimum mass includes the driver, knowing their weight allows the team to calculate the car's and driver's combined weight accurately. This ensures compliance with the regulations and provides a fair playing field. Drivers are weighed with their full race gear, including helmets, as it is considered part of their weight. This also enables the FIA to verify whether the correct amount of ballast has been added if necessary.
Why do F1 drivers lose weight during a race?
F1 drivers experience weight loss during races primarily due to intense physical exertion and the demanding conditions they face. Racing in hot and humid environments while wearing tight racing suits leads to significant sweating and subsequent dehydration. It is estimated that drivers can lose between 2-3kg (4-6lb) of weight during a race, depending on the conditions. By carefully monitoring their weight, medical teams can ensure drivers remain adequately hydrated and adjust their fluid intake accordingly. Additionally, weight loss during a race can impact the intensity of the drivers' training for the upcoming week.
Furthermore, F1 cars have specific weight limits that must be adhered to. Without fuel, the minimum weight of an F1 car is around 740kg. By losing weight during the race, drivers contribute to keeping the car's overall weight within the specified limits.
Do F1 drivers have a weight limit?
Yes, FIA rules state a minimum weight requirement for Formula 1 drivers. The current minimum weight for an F1 driver is 80kg (176 lbs). Since the drivers' heights vary significantly, ranging from shorter drivers like Yuki Tsunoda at 5'2" to taller drivers like Alex Albon and Esteban Ocon at 6'1", weight fluctuates among them. Suppose a driver weighs less than 80kg, which is the case for most drivers. In that case, the difference is compensated by adding ballast.
This ballast is strategically placed in the cockpit and cannot be distributed elsewhere in the car to improve balance. The weight of the driver's helmet, race suit, and shoes is also included in the total weight. Implementing the 80kg minimum rule in 2019 aimed to reduce the advantage that lighter and shorter drivers previously had. Before this rule, the driver's weight was considered in the car's overall weight, allowing more lightweight drivers to provide teams with more flexibility to enhance the car's balance.
The weight of an F1 car is a delicate balance between performance, safety, and compliance with FIA regulations. Teams invest significant efforts in achieving the optimal weight distribution and strive to stay as close to the minimum weight limit as possible.
The evolution of F1 weight reflects advancements in safety, technological innovations, and changes in regulations over the years. As the sport progresses, finding the ideal weight and maximizing performance will continue to be crucial in the highly competitive world of Formula 1 racing.
