Red Bull question the legality of Mercedes front wing:

"... As first revealed by Auto Motor und Sport, Red Bull are examining the front wings of their rivals. Formu1a.uno has gathered from reputable sources that the engineers at Milton Keynes, under the supervision of Paul Monaghan, are looking closely at the new Mercedes front wing.
This specification was first introduced on Russell’s car in Monaco. It was then brought to both cars in Canada, and to devastating effect. An unofficial request has been submitted to the FIA technical office to monitor the flexing at the W15’s front wing and nose. The Mercedes front wing has always been within legal limits during the FIA’s static checks.
However, teams are also able to activate flexing at certain load ranges during the lap. Listening to various insiders, the television images confirm that the front wing of the new specification W15 flexes more compared to the initial specification. This is an issue at Mercedes we have previously analysed. ...
HAS THE 2023 TD018 DIRECTIVE ALREADY BEEN BYPASSED BY THE TEAMS?
The theme of flexing has always been very present in these F1 technical regulations. In both 2022 and 2023, the FIA intervened and tweaked the technical regulations to mitigate the flexions of components such as the floor and spoilers. Last October, the FIA technical office officially implemented Technical Directive 18 to mitigate the use of overly flexible composite carcasses on the front wing structure. ...
The TD018 of 2023, which came into force through the political weight of some teams, greatly limited Aston Martin. Over the winter break, teams worked to reach pre-TD018 flexion levels while still complying with article 3.2.2 of the regulation – which limits flexions around the front wing.
“Observing the teams, we saw how they manage to create relative movements in the area of the nose attachment and in the external part near the lateral fins,” Nikolas Tombazis commented last year. “The teams invest a lot of resources to create surfaces that resist our load tests, but that appear to be made of elastic material on the track.”
With the fight at the front intensifying, teams are paying extra attention to the work of rivals. This scrutiny is to either copy or ask for clarification on potentially suspicious elements. ..."
