Formula 1 is all about details, and this approach applies to post-race procedures.

The FIA (Fédération Internationale de l'Automobile) play a crucial role during a Grand Prix weekend, ensuring cars are compliant through a process called "scrutineering."

The Sporting News takes a closer look at one of their many important steps – weighing drivers.

Why do F1 drivers weigh themselves after a race?

There are two main reasons drivers hop on the scales post-race: car weight limits and driver health.

Car weight limits

F1 cars have a minimum weight, which is established in an attempt to create an even playing field.

Without fuel, cars must weigh at least 740kg (1,631lbs).

Drivers must be weighed after a race because they are included as part of the minimum car weight.

In 2019, a minimum driver weight of 80kg (176lbs) was introduced. 

This figure includes all safety equipment such as the helmet, head restraint, overalls, gloves and shoes.

Most drivers do not hit this mark, so a weighted ballast is applied to the cockpit of the cars. 

The ballast cannot be fixed anywhere else in car to achieve a speed advantage.

If teams do not reach the minimum car weights – which includes a driver's weight – they could face a penalty, including disqualification.

Driver health 

Motorsport is a demanding craft, and F1, in particular, pushes drivers to the limit.

In fact, drivers can lose between 2-4kgs (4.5-9lbs) through sweat loss during a race.

This is due to several factors, including the sheer physicality and G-force, the length of a race, high temperatures inside the car, wearing a thick race suit and external weather conditions. 

In hot and humid climates (e.g. Singapore) drivers can lose a dangerous amount of weight.

By performing a weigh-in at the end of a race, medical staff can make important health assessments.

How much does an F1 car cost?

The exact cost of an F1 car is hard to confirm, but they come to a sum of approximately US$15 million (€15.8 million) each, according to Red Bull.

For the 2024 season, teams are allowed to spend a maximum of $135 million (€128m) on materials and activities related to car performance.

This cost cap has been introduced in an attempt to level the playing field, allowing smaller teams to potentially challenge race-winning constructors.

Before 2021, up to $400 million (€379m) was spent on the construction and development of a top-level F1 car, per Motorsport Magazine.

The cost cap was then reduced significantly to $145 million (€137.5m) in 2021 and $140 million (€132.7m) in 2022.

With a cap still in place, FIA scrutineering ensures teams are competing legally each race weekend.
