The Formula 1 world is in an uproar after McLaren announced that they will not be making any changes to the front wing of their MCL39 car for the British Grand Prix, despite a recent FIA rule change that sees stricter testing of flexible front wings. The decision has sparked heated debate in the paddock, with rivals such as Red Bull and Ferrari expressing concern over the British team’s approach. As Formula 1 gears up for a thrilling race weekend at Silverstone, McLaren are in the spotlight, not only for their dominant performance this season, but also for their controversial decision to leave their front wing unchanged.
The FIA ​​introduced stricter testing for flexible front wings earlier this year, a topic that has been a source of controversy since 2024. A new technical guideline came into effect at the Spanish Grand Prix, limiting the maximum deflection of front wings to 10mm under static testing, down from the previous 15mm. The change came after complaints from teams, most notably Red Bull and Ferrari, who accused McLaren and Mercedes of taking advantage of overly flexible front wings. These wings were said to reduce drag on the straights and generate more downforce through corners, providing a significant advantage. While teams including Red Bull, Ferrari and Mercedes introduced new front wings at Barcelona to comply with the regulations, McLaren surprised by stating that its existing wing already met the new requirements, a position it will maintain for Silverstone.
McLaren team principal Andrea Stella has defended the decision, saying the MCL39 wing has always been within the regulations. In an interview with Sky Sports, he insisted the team did not need to make any significant changes as their design already took the stricter testing into account. However, his explanation has drawn scepticism from rivals. Red Bull consultant Helmut Marko suggested that McLaren’s championship lead was partly due to their advanced tyre management and aerodynamic design, but he openly questioned whether their front wing fully complies with the new regulations. Red Bull team principal Christian Horner went further, calling the situation “potentially game-changing” for the championship, given the small differences between the top teams.
McLaren’s decision not to modify the front wing has also led to speculation over their reliance on the current design. In Canada, the team introduced a striking update, with a front wing that featured “mermaid tails”, an innovation aimed at optimising airflow. While the update appeared to be track-specific, McLaren stressed that it would benefit their performance on multiple tracks. At the Austrian Grand Prix, where Max Verstappen qualified only seventh, Lando Norris and Oscar Piastri dominated with a 1-2 finish, underlining their technical superiority. However, the question remains whether McLaren’s refusal to modify the front wing is a strategic risk, given the FIA’s increased scrutiny.
Reactions in the paddock ranged from admiration for McLaren’s confidence to frustration over a perceived grey area in the rules. Ferrari team boss Fred Vasseur noted that the timing of the rule change, just after the Monaco Grand Prix, meant extra costs for teams that had to modify their wings. He called for more consistency in the enforcement of the rules. McLaren, meanwhile, remained unmoved, with Stella insisting that their focus is on maintaining their lead in the Constructors’ Championship, where they currently lead thanks to four wins from Piastri and one from Norris.
The British Grand Prix, a home race for McLaren and Norris, will be a crucial test. Silverstone’s high-speed corners and long straights will put the effectiveness of McLaren’s front wing under the microscope. Fans and pundits alike will be eagerly awaiting the performances of Norris and Piastri, who have both indicated their desire to shine in front of their home crowd. Meanwhile, the tension surrounding the FIA ​​rule change remains palpable, with teams hoping McLaren’s gamble will ultimately prove costly. As the Formula 1 world holds its breath, the race weekend at Silverstone will not only be a battle for points, but also a test of McLaren’s technical and strategic prowess.
