Formula 1’s governing body, the FIA, has announced stricter tests for rear wings starting with the upcoming Chinese Grand Prix in Shanghai. This move follows increased scrutiny over McLaren’s car performance and aims to ensure compliance with technical regulations.
Tighter Regulations on Slot Gap Variation
According to Article 3.15.17 of the technical regulations introduced this season, the distance between the main wing and the flap, also known as the ‘slot gap,’ must not vary by more than two millimeters under a vertical load of 75 kilograms. However, for the Chinese Grand Prix, this limit will be drastically reduced to just 0.5 millimeters. Due to the short preparation time between races, an additional tolerance of only 0.25 millimeters will be permitted.
McLaren’s Performance Under Scrutiny
The decision to tighten regulations comes after an FIA analysis of the season-opening race in Australia, where McLaren’s Lando Norris secured victory ahead of reigning world champion Max Verstappen. While all cars in Melbourne passed the required tests and were deemed legal, the FIA determined that enhanced scrutiny of the upper rear wing was warranted.
Addressing Controversies from Last Season
During the latter half of the previous season, rival teams raised concerns over McLaren’s rear wing design, suggesting that parts of the upper wing element appeared to fold upwards at high speeds, potentially reducing drag and providing a performance advantage. Despite passing all stress tests, McLaren made modifications to its car to dispel any doubts about its legality.
Impact on Teams Moving Forward
With the new stricter testing measures, all teams will need to ensure their cars comply with the updated limits. The FIA’s decision reinforces its commitment to maintaining a level playing field and preventing any aerodynamic loopholes that could give certain teams an unfair edge.
As Formula 1 heads to Shanghai for the second race of the season, all eyes will be on how teams adapt to the reinforced regulations and whether McLaren can maintain its strong start under the increased scrutiny.
