RBR made an official protest at FIA against Mercedes and Mclaren.
They are saying that those 2 teams are using flexible wings... what an hypocrisy.
Do you remember 4 years ago the wings of RBR?
Anyway FIA already responded and said that no rules has been broken.
This controversy involves many more teams, as Maranello and Milton Keynes are also demanding to know from the FIA what the limits are for Mercedes and McLaren to use this accessory.
In fact, if I remember correctly, the use of flexible wings began to be a hot topic, especially after the Monza GP, but this controversy has been going on since the beginning of the year, when these teams discovered that using this area is one of the options for resolving balance issues affecting the current generation of cars.
The fact is that there is no ban on this and the FIA itself has said several times that it has no interest in making any changes to the rules this season and, if it finds it necessary to react, this will only happen from the beginning of 2025, if it happens... since the regulations are expected to be officially changed only in 2026.
Obviously, it is normal for some teams to be concerned about the growing competitiveness of McLaren and Mercedes in the last stages, so these disputes will always occur until there is a regulation on this.
