The FIA has officially cleared McLaren of any wrongdoing following an investigation into the team’s tyre cooling methods during the 2025 Miami Grand Prix.
This inquiry was prompted by concerns from rival teams, notably Red Bull, who suspected McLaren of using unconventional techniques to manage tyre temperatures.
Red Bull’s Concerns and FIA’s Response
Red Bull raised suspicions after thermal imaging suggested McLaren’s rear brake drums exhibited cooler temperatures compared to other teams. They theorised that McLaren might be employing a method involving the injection of water or other substances to cool the tyres, potentially offering a competitive advantage.
In response, the FIA conducted a thorough investigation, including detailed inspections of McLaren’s braking systems and tyre assemblies. The governing body found no evidence of any rule violations or the use of prohibited cooling methods.
McLaren’s Innovative Approach
McLaren attributes their superior tyre management to innovative engineering, particularly in their brake duct design. Reports suggest that the team may be utilising phase-change materials within the brake drums. These materials can absorb and release heat at specific temperatures, helping to maintain optimal tyre performance without breaching regulations.
Team CEO Zak Brown addressed the allegations with a touch of humour. Appearing on the pit wall with a water bottle labelled “tyre water,” a playful nod to the controversy.
Implications for the Championship
With the FIA’s clearance, McLaren undeniably continues its strong performance in the 2025 season. Drivers Oscar Piastri (1.61) and Lando Norris (2.81) have consistently finished at the top, showcasing the effectiveness of the team’s strategies and innovations.
As the season progresses, rival teams will undoubtedly analyse their methods, seeking to understand and potentially replicate their success within the bounds of the regulations.
The FIA’s investigation reaffirms McLaren’s compliance with Formula 1 regulations, highlighting the team’s commitment to innovation and excellence. As the competition intensifies, McLaren’s approach may set new standards for engineering ingenuity in the sport.
