**McLaren in the spotlight: FIA investigation into alleged technical illegality on MCL39**
Woking, 23 May 2025 – A bolt from the blue has shaken the Formula 1 paddock: McLaren is at the centre of an official FIA investigation for an alleged technical illegality on its MCL39, the single-seater that dominated the start of the 2025 season. According to rumours leaked just three minutes ago, secret data relating to the rear brake cooling system have been released, raising suspicions about possible violations of the technical regulations. The news, which is making the rounds on the web, has reignited the debate on a car already under scrutiny for its extraordinary performance.
The McLaren MCL39, which was unveiled as a surprise at Silverstone in February, has impressed with five wins in the first six races, consolidating a significant lead in the drivers’ and constructors’ championships. However, the Woking team’s dominance has fuelled suspicions from rivals, particularly Red Bull and Ferrari, who have repeatedly suggested that the MCL39’s performance is too good to be true. The accusations centre on the rear brake cooling system, which is said to ensure unprecedented efficiency in managing tyre temperatures, a crucial factor for success on the track.
According to sources close to the FIA, the investigation was launched after the release of confidential technical documents, which detail an alleged configuration that does not comply with Article 11.5 of the technical regulations, which prohibits the use of brake cooling fluids. After the Miami Grand Prix, the FIA had already carried out in-depth checks on Oscar Piastri’s MCL39, but without finding any irregularities. However, the new leaked data seems to have rekindled the Federation’s interest, which is now analyzing the incriminated components more carefully.
McLaren CEO Zak Brown responded in his usual tongue-in-cheek style: “We are used to suspicion when we win. Our car has been checked several times and it has passed every test. We will continue to focus on the track, not the chatter.” However, Brown’s words did not appear to have pacified his rivals, with Red Bull’s Christian Horner saying: “It’s strange how McLaren manages the tyres without compromise. Something doesn’t add up.”
Meanwhile, images from technical expert Giorgio Piola have revealed details of the air passages in the rear brake drum, highlighting an innovative design that could be at the heart of the controversy. The FIA has promised to publish the results of the investigation during the upcoming Emilia Romagna Grand Prix, but the paddock is already buzzing. Can McLaren prove the legality of its MCL39, or will this affair risk overshadowing a triumphant season so far?
As fans anxiously await further developments, one thing is certain: Formula 1 never ceases to surprise, and this spy story could have unpredictable consequences for the 2025 championship.
