FIA Clears McLaren MCL39 After In-Depth Post-Race Inspection Following Miami GP
Formula 1’s governing body, the FIA, has officially confirmed that McLaren’s MCL39, driven by Oscar Piastri, has fully complied with the 2025 F1 technical regulations. This comes after a comprehensive and detailed investigation was launched following the Miami Grand Prix earlier this month.
McLaren has emerged as the dominant force at the beginning of the 2025 season. The team, which won the Constructors’ Championship last year, has managed to maintain that momentum with an impressive streak of five victories in the first six races. This formidable run has placed them at the forefront of the title race early in the season.
Oscar Piastri has been a key figure in McLaren’s resurgence, winning four of the last five Grands Prix, including a convincing performance in Miami. His consistency and speed have earned him a 16-point lead over his team-mate Lando Norris in the Drivers’ Championship standings. Piastri’s form has not only boosted McLaren’s championship ambitions but also brought increased scrutiny to the team’s performance, particularly the engineering behind the MCL39.
Following the Miami GP, the FIA conducted a detailed technical inspection of the MCL39, focusing specifically on its rear braking system. According to reports from PlanetF1.com, this component was believed to be a central contributor to McLaren’s superior tyre management — a crucial factor in their race pace and overall advantage over rival teams.
FIA’s technical delegate Jo Bauer spearheaded the inspection, which was described as “intensive” and “extensive.” The investigation aimed to ensure that all aspects of the car, especially those contributing to its competitive edge, were in full compliance with the 2025 F1 regulations.
It is standard procedure in Formula 1 for cars finishing in the top ten to undergo post-race inspections. However, the FIA can select any car at random for deeper technical checks if there are concerns or suspicions about possible rule infringements. In this case, the spotlight fell on McLaren’s MCL39 after another dominant performance by Piastri.
After completing the thorough analysis, the FIA found no breaches or irregularities in McLaren’s car. The rear braking system, along with all other inspected components, adhered strictly to the regulatory framework set out for the current season. The governing body concluded that the car’s design and systems were legal and within the permissible boundaries of the technical rulebook.
This verdict not only solidifies McLaren’s legitimacy in their strong start to the season but also affirms the team’s engineering prowess. With the FIA’s approval, McLaren can now continue their campaign without any looming technical disputes, and the rest of the paddock is left to respond to the challenge posed by the MCL39’s exceptional performance.
As the F1 calendar progresses, attention will turn to whether any of the rival teams can close the gap to McLaren, or if Piastri and Norris will continue to dominate in what is shaping up to be a potentially historic season for the Woking-based outfit.
