The debate between McLaren CEO Zak Brown and Red Bull Racing centers on a controversial front-bib device on the RB20 car. He questioned the legality of Red Bull’s contentious front-bib device, suspecting it gave the team an unfair competitive advantage. Zak Brown called for both current and former Red Bull team members to sign an affidavit confirming that the device was not used under Parc Ferme conditions.

However, Christian Horner dismissed it as mere “paranoia” and “moaning” from a rival, claiming it was just a distraction. Horner asserted that the debate over the device was overblown and emphasized that Red Bull complies with all regulations. Brown was disappointed by the response and is committed to investigating whether Red Bull used the bib under Parc Ferme.
