Close to the top of a hotly-contested season roles had been reversed as Crimson Bull took concern with Mercedes’ rear wing design at varied races, together with Brazil, believing it had spotted “score marks” which allegedly pointed to extreme flexing to extend straightline velocity.

After conducting further, exploratory checks through the Qatar Grand Prix weekend, the FIA mentioned it had not discovered any proof of foul play, but it surely did establish methods to enhance its strategies for finishing up flex exams, that are set to be tweaked in 2022.

“The entrance wing in 2022 is a large factor but it surely nonetheless has a really stringent set of tips on stiffness, so I feel there’ll at all times be a couple of methods to play however I don’t suppose there’s going to be one thing simple to use. 

“You’ve acquired a few completely different parts on the automobile which might have a sure degree of stiffness, which you can exploit legally, so there are numerous new instruments to play with in 2022.
