At the upcoming Spanish GP, the FIA will be enforcing stricter controls on the use of flexi-wings – wings that move under aerodynamic pressure. McLaren, which made a significant leap in the championship last year, was particularly suspected of such ‘illegal’ tricks. The papayas were once again the team to beat this year, but the cards may be reshuffled in Barcelona.
The alleged flexi-wings of McLaren have been a hot topic of discussion. Last year, the papayas were already under scrutiny when camera footage of the front and rear wings were compared to those of other teams. Similar footage went viral again this season. However, the British racing stable denied that movable parts were decisive for the performance of the MCL39. Nevertheless, rivals Red Bull and Ferrari openly advocated for stricter tests – both teams expressed their opposition to the use of flexi-wings.
The FIA decided during the winter, despite initially having no plans to tighten the technical regulations, to implement changes after all. Stricter tests regarding the flexi-wings were postponed until the upcoming Spanish GP, a third of the way into the anniversary season. Opponents of McLaren, including Max Verstappen, hope that a ‘level playing field’ will finally be created in Barcelona.
Stricter Tests
The new tests concern the amount of flexibility in the front wings. This specific part is now subjected to a load of up to 1000 newtons at two points. Previously, the carbon was allowed to bend a maximum of 15 millimeters under this load. When measured on one side, a leeway of 20 millimeters was permitted. However, starting from the Spanish Grand Prix, the wings must be stiffer. During the same tests, a flexibility of 10 millimeters and 15 millimeters respectively is now allowed.
The rules regarding the flaps on the front wing are also being tightened. Under a load of 60 newtons, these can now bend 3 millimeters. Previously, a leeway of 5 millimeters was allowed. It remains to be seen to what extent these stricter guidelines will affect the established order. McLaren has so far denied that the new requirements will affect the MCL39, although the Brits – like almost all other teams – are bringing a number of upgrades to Barcelona. Red Bull and Ferrari are the most hopeful about their latest adjustments. The Italians, in particular, place a lot of trust in their new front wing. Will they set the standard? Only time will tell.
