The Formula 1 world has been rocked once again by a heated confrontation between McLaren and Red Bull. McLaren CEO Zak Brown has strongly criticized what he calls “unrealistic” accusations against Red Bull Racing. Tensions escalated during the Miami Grand Prix weekend on May 10, 2025, when Brown called on the FIA to fine Red Bull for its repeated claims regarding the legality of the McLaren MCL39. Shortly after, world champion Max Verstappen and FIA President Mohammed Ben Sulayem joined the conflict, making the matter even more explosive.
The crux of the dispute revolves around Red Bull’s accusations that McLaren uses illegal methods to cool its tires, including injecting small amounts of water into the tires to regulate temperature and reduce wear. These allegations first surfaced in 2024, when Red Bull used thermal imaging cameras to inspect McLaren tires. The FIA and tire supplier Pirelli investigated the matter in Brazil and found no evidence of a violation, but Red Bull persisted. In Miami, the situation came to a head when Brown Red Bull challenged the FIA’s filing of a formal complaint, instead airing “false” and “light” accusations in the media. He suggested that teams that filed unfounded complaints be fined at least $25,000, an idea surprisingly supported by Ben Sulayem, who even proposed a fine of $50,000.
Brown’s performance in Miami, where he conspicuously drank a bottle labeled “Tire Water” during a press conference, was a direct snide taunt toward Red Bull. He emphasized that teams that make serious accusations must submit them officially and be prepared to face the consequences if they are wrong. “These kinds of frivolous accusations are only meant to distract,” Brown said, referring to Red Bull’s strategy. His call was supported by Mercedes team principal Toto Wolff, who noted that Red Bull’s complaints often appear unfounded and distract from its own problems.
Max Verstappen, Red Bull’s star driver, reacted strongly to Brown’s statements. He dismissed the accusations about McLaren’s tires as “nonsense” and emphasized that he was not distracted by such stories. “I’ve been in F1 for 10 years and I don’t waste my time with these kinds of rumors,” Verstappen told reporters. He emphasized that teams are constantly looking to trick each other with technical tricks, but that McLaren’s suggestions about the Red Bull car, such as an alleged illegal approach to BIB in 2024, have also proven unfounded. Verstappen’s team principal, Christian Horner, agreed and reminded him that McLaren had itself inquired about Red Bull’s front suspension in 2024, demonstrating that these kinds of accusations are inherent in the competitive nature of the sport.
FIA President Ben Sulayem attempted to calm things down by stressing that accusations must always be accompanied by concrete evidence and a formal complaint. “You can’t accuse anyone without a written complaint, and this protest should be paid,” he said, thus supporting Brown’s proposal. He added that the FIA was investigating the matter, but that no evidence of illegal practices had been found at McLaren. However, this stance was criticized by some X fans, who speculated about possible conflicts of interest due to Ben Sulayem and Brown’s former friendship, a relationship that was once strained but now appears professional.
The rivalry between McLaren and Red Bull is particularly intense this season. McLaren leads the Constructors’ Championship thanks to the excellent performances of Lando Norris and Oscar Piastri. Red Bull, facing problems with the RB21, is feeling the pressure and appears to be diverting attention from its own weaknesses with accusations. In the meantime, McLaren remains focused on the title fight, with Brown calling for greater transparency and stricter rules to discourage unfounded claims.
This saga highlights the fierce competition and political gamesmanship in Formula 1. As McLaren and Red Bull battle for supremacy, the FIA’s response to this issue will be crucial to maintaining a fair sport. Fans eagerly await further developments, both on the racetrack and in the future.
