What is new in 2025 rules of F1?

The 2025 season of Formula 1, the last of the current rules, will kick in Australia as Albert Park hosts the season opener – and once cars are hit on the road, there are some changes in the rules.

Although the 2026 season has promised the biggest change in the technical regulations of F1 for some time, as both the rules operating the development of chassis and powertrain will come together in the game, the rule book is somewhat stable as the current generation of cars was introduced in 2022.

Probably the biggest twist for the 2023 season emerged as the floor height and fence was trimmed by 15 mm, and the defuse ‘throat’ (the point at which the defuser begins to expand) was raised by 10 mm. This was part of a comprehensive effort to reduce the effects of porpizing seen in the season of the woman of the rules, which first began with the introduction of a “oscillation metric” through 2022 to ensure that cars were not growing high and down.

Those changes are generally considered effective, which means that the FIA ​​has not had to stage any further intervention – at least until the dispute over the 2024 Flexing aerodynamics began to emerge from wooden work.

Originally, the governing body was reluctant to do so, but due to changes being implemented for 2025, their constant use and concerns from the more curious teams were more curious for the discipline of aerolasticity.

This driver also follows the introduction of the cooling system, which will be used in the race where the governing body declared that the temperature is suitable for them to avoid drivers suffering from diseases related to heat. Its roots are in 2023 Qatar Grand Prix, where a handful of drivers eliminated warm-fotting at the medical center amid conditions.

New wing regulations

Both front and rear wings will be subjected to the revised rules, which will be to drive away the flexi-wing uproar in the previous season.

The rear wing is now subject to the Flex Test which will be effective from the season-opening Australian Grand Prix. The mainplane can no longer flex more than 6 mm in the direction of the load applied, while the upper flap cannot carry more than 7 mm when the load is applied horizontally. In addition, the followed edges of the rear wing can produce only 3 mm maximum flax.

The dimensional rules for the rear wing have also been modified; The slot gap between the two wing elements has been reduced to the 10–15 mm range. With DRS open, the upper range remains at 85 mm.

To reduce the possibility of teams exploiting “mini-DRS” effects McLaren Baku is used for great effects, where the front corners of the upper wing flap raised a slightly raised to best MCL38 with a slight top speed benefit, the rules now mandate that the wing is subject to only two states: DRS, and DRS off. The slot-gap size should not only fit within the limits determined by the rules, but also remain stable within the mode. For example, a wing with a defined 10 mm slot gap shape is not allowed to expand up to 13 mm, while the car is on track.

In 2025 Technical Rules, Article 3.10.10 states that: “DRS failure or except for the position of infection from one position, DRS bodywork can only have 2 positions, such as the status of DRS bodywork should be the same before and after each state of deployment. The time of infection between 2 posts should be reduced by 400ms.”

The new flex tests of the front wing will not be effective to Spanish Grand Prix, teams will be given some papers to maintain their discovery of front wings for the first eight races of the season before switching on a more rigorous imagination in Barcelona. This will cut the maximum vertical flax allowed in tests from 15 mm to 10 mm with 1000n load.

In addition, the followed edge of individual wing elements can not flex more than 5 mm with a vertical 60N load, which will be reduced by 3 mm in Spain.

Increase in minor weight and driver cooling equipment

Minimum driver weight gain by 2 kg will increase the overall minimum weight of an F1 car by 800 kg, and any ballast used to get minimal weight should now be made of a material with a density of 7500 kg/m.³ – Below last 8000kg/m³ Permission.

In the event of the FIA ​​declaring “heat hesard” – from 31C environment temperature, as the FIA ​​temperature in the circuit was given by the average of the sensor – the driver will automatically increase from 5 kg to cover for the increased mass of the driver cooling equipment and is used to provide electricity.

This chillout will be manufactured by motoristsports, and contains a fireproof underlay shirt with 48 meters tubing, through which cool liquid flows – an internal connected mounted control box that cools and pump the fluid in the shirt. Fluid can be an aquatic solution of air, water, or sodium chloride, potassium chloride or propalin glycol. The cold in the system should also have a potential value of global warming of less than 10.

Currently, cooling system Is not mandatoryHowever the weight range will still be applicable – 500 grams will be deployed within the cockpit area with ballast. Since the system will be fully integrated into 2026 packages, it will be necessary for all drivers to wear it, whether any race should be declared with the risk of heat.

Any more fast-lapt point: Sporting Regulation Change

One of the major changes in the 2025 format comes with the removal of the championship point given for the fastest lap of the race, which was honored until the holder ended within the top 10.

Although the drivers intend to give more reasons to take risks during the race to secure an additional point, it is often either honored to a driver, who simply replaces the tire late if they built a pit-stop window behind the car, or were taken away to stand up to the championships by a runner and outside the gamemanship.

Monaco also gets its special section in sports rules after the decision to make the two-stop race mandatory in the princely state. In the condition of a dry season, the two-cum mandate still applies, and any driver who fails to complete both stops will receive a fine of 30 seconds in his race time.

The ban on testing of previous cars (TPC) has also been tightened. Teams are allowed to nominate only one car for TPC duties and do not allow it to test in a circuit within 60 days of being used in the current championship.

In a team, the race driver can do TPC tests for only 1000 km per calendar year in four days; Ferrari Race drivers appeared to use their own allocation Charles Lakeler And Lewis Hamilton Before the season starts.

The FIA ​​has also discontinued flaws related to the formation laps and damaged cars, and any car starting from Pitlane should now include the rest of the area for the lap formed before exiting the pit for the start.

Also, to avoid the situation in Canada last year Sergio Perez Despite his red bull RB20 continuing on the track despite heavy losses, the race director will be able to pull and order a driver if they suffer significant damage to the car.

The rule states that “any driver’s car suffers significant and clear disadvantage to a structural component, resulting in a situation that presents an immediate risk of endangering the driver or other people, or who has an important failure or mistake in the car, meaning that it can stop any other competitive without disrupting any other contestant, because it should not leave the track as soon as possible.

“At the sole discretion of the race director, a car should be understood as a structural component, or such a significant failure or mistake, such as important and clear losses, the competitor can be instructed that the car should leave the track as soon as it is safe to do so.”

The restriction on the amount of gearbox used in one season is now lifted in the rules, as the FIA ​​is satisfied that the reliability has presented these moots.
