The eyes of the insiders in the Mexican pit lane are on the controversial new front wing brought for the first time by Mercedes to Austin. In fact, the Silver Arrows in Texas had not fitted the updated wing, giving rise to rumors of an alleged irregularity found by the Federation. In Mexico City, the controversial solution is not presentan absence which however does not exclude his return to Brazil.
In the United States, the editors of Auto Motor und Sport reported that the alleged regularity problem concerned the dimensions of the bridge supports between the last two profiles of the wing, exploited for aerodynamic purposes to research the outwash effect of diverting flows towards the outside. A first vision of the virtual CAD models of the supports in question would have enjoyed the approval of the Federation, but the verification on the spot would have revealed a geometric problem of the supports, guilty of not respecting the geometric limits imposed by the regulation. Also on the basis of what has been reported, Mercedes would have been free to use the solution after making the appropriate changes to the flow deviators.

The images arriving from Mexico highlight how Brackley’s stable removed the five mounts of contention, replacing them with two more traditional elements. The team chose to modify the new wing rather than revert to the previous specification, so as to be able to benefit from the other updates to the aileron introduced in Texas, concentrated in the vertical drift area of the endplate. However, it cannot be excluded that the five supports with aerodynamic function may return to the W13 starting from the Brazilian Grand Prix.. The five days between the Austin Grand Prix and Mexico free practice would still have made it difficult for the team to be able to make the required changes and ship them overseas in time. It will be necessary to wait for the trip to Sao Paulo to understand if Mercedes was forced to definitively abandon the controversial solution or rather if it only needed more time to make the changes necessary to pass the technical checks.
