Article A2.3.4 of the general regulatory provisions in the all-new Section A of the new Concorde Agreement, officially announced on Friday, states: “Each F1 Car must bear the FIA logo, in either blue or white, with a height of at least 75mm.”

It further adds: “This logo must be positioned on the top of the nose or on either side of the nose and be visible from the side of the car.”

Additionally, a footnote from the World Motorsport Council’s (WMSC) final meeting of the year confirms the return to a single test session starting in 2027, replacing the triple test scheduled to take place between January and February in Barcelona and Bahrain.

For the upcoming season, the governing body has allowed teams to run significantly more mileage across multiple sessions, giving them the chance to get to grips with the new generation of cars — set to be one of the most important regulatory revolutions in recent years.

As noted earlier, Formula 1 has signed its ninth Concorde Agreement, covering the 2026–2030 period, which is now officially in effect.

This new contract kicks in with the start of the year, coinciding with a landmark season as the sport introduces major technical regulations and phases out the current generation of ground-effect cars.

So, what does it actually entail, and why does it matter so much? Here’s a more detailed breakdown.
