From technical directives to developments: key factors that will decide the 2025 F1 World Championship

Today at 12:40 PM

The upcoming Formula 1 World Championship is expected to be more competitive than previous seasons, anticipating a double fight for the title influenced by multiple factors. The current curiosity focuses on who will start in a favorable position, without neglecting the subsequent development, which will be more complex than ever due to technical and logistical complications, with the 2026 Formula 1 regulations looming. Additionally, Ferrari and the rest of the teams are facing stricter flexibility tests for the front wing, a technical directive that, if the championship proves to be balanced, may not be the last.

Starting point
The competitiveness of the initial projects will determine the legitimacy of the title aspirations of the individual contenders. However, it would be wrong to jump to conclusions after just the Australian Grand Prix in Melbourne for two main reasons. The first is that each team will follow its own learning curve, adapting setups to make the best use of the available package, achieving improvements on the lap time even without any updates. A clear example is McLaren's 2024 car, which, even before the Miami aerodynamic upgrade package, showed consistent progress in the first months, demonstrating a gradual optimization.

For 2025, the focus is primarily on Ferrari. The SF-25 single-seater represents a project that is fundamentally different from its predecessor, not only because of changes to the architecture and suspension but also in its handling, with a front end that is notably more pointed than before. This suggests an new package that should have a lot of room for growth, with Technical Director Loic Serra explicitly expecting a rapid development curve for the Maranello team’s technicians and engineers.

The second reason why the Melbourne weekend will not be a definitive verdict is the partial picture that will emerge in Australia. In such a varied calendar with cars that are highly sensitive to track types, track surface, and environmental conditions, there are no longer fully representative circuits. The competitiveness of the initial projects will be fully appreciated after the first month, and it will still be an essential reference for the title race's dynamics. With the 2026 Formula 1 regulations on the horizon, the initial performance of each car will determine how much each team is willing to believe in and develop their current project before fully committing to the next one.

Developments
Never before has developing the cars without making mistakes been such a challenge. Ground-effect Formula 1 cars have shown that the more aerodynamic downforce is increased, the greater the risk of unpredictability in handling. Without side skirts, the intensification of the ground effect exposes the car more to external turbulence, adding to all those physical phenomena that are unpredictable with design tools, only becoming evident when it is too late. Ferrari's bouncing in 2024 and the gradual deterioration of Red Bull’s balance are proof of how costly development missteps can be.

"The competition is becoming tighter and tighter, and we're talking more and more about details," said Fred Vasseur last February. "Now, when we bring an update, we're talking about just a few points of downforce. To quantify them, you need good tools and the right decisions. This means that simulation tools are increasingly crucial. For performance purposes, moreover, drivability plays a bigger role than in the past, and this means that the simulator is also more important." – the French manager pointed out.

The technical directives
Starting with the Australian Grand Prix, new deformation criteria will come into effect for the rear wings and beam wings, while at the Circuit de Catalunya in Barcelona, stricter tests will debut for the flexibility of the front wings. These restrictions should not be underestimated, as, in addition to reducing aerodynamic drag on the straights, the flexing of the front wing helps balance the car by fighting oversteer at high speeds and increasing understeer in slower corners. However, the recent tightening of the FIA regulations may not be enough to put an end to the controversies. Experience shows that for every constraint, teams always find new ways to exploit the deformation of the wing profiles, while still passing the checks from the race officials.

The flexible wing directives might not be the only technical directives of the season. If the 2025 Formula 1 championship really does deliver a title fight between two or more teams, it is inevitable that each team will request clarification and checks against the others, with the likely emergence of new cases. The dogma for everyone will be to push the limits of the regulations without breaking them, but equally crucial will be the ability to react swiftly to any directives from the Federation.

Tire factor
A new feature for the 2025 Formula 1 season is the Pirelli tires, which have been revised in both the compound and the construction. Therefore, teams will have to monitor their learning curve on this front as well, adapting setups and driving strategies to make the most of the new product. The pre-season testing session at the Bahrain circuit did not show significant changes, but the verdict from a race weekend on a different track is still awaited. One of the goals of the new Pirelli tires is to reduce graining wear, which has been one of McLaren’s main weaknesses in 2024, and a result may already be visible at the 5.278-kilometre Albert Park Grand Prix Circuit in Melbourne.

Human factor
The hope is that the new season will reflect the dynamics of the previous one, with a general balance, four teams fighting for victory, and power dynamics evolving race by race depending on the characteristics of each track, with the hope of course that Ferrari will come out on top after narrowly missing out on last year’s Constructors’ title. In such a scenario, where design differences translate into marginal differences on the stopwatch, the execution of the weekend will be decisive for the Maranello team, both in terms of factory setup preparation and the work done on track by mechanics, engineers, and the two drivers, Charles Leclerc and Lewis Hamilton.

Ferrari team principal Frederic Vasseur has reiterated this several times: in addition to securing victories when conditions allow, what will count for the Italian side is the ability to minimize losses during weekends when the inevitable limitations of the aerodynamic package will prevent aiming for the maximum result. Retirements will be costly, both figuratively and literally. Every euro spent on spare parts will be one less euro for updates, and this applies not only to aerodynamics but to power units as well, whose replacements will impact the engine budget cap and the final development of the 2026 Formula 1 power unit, a project that will hang like a sword of Damocles over all the teams this year.
