F1 team boss 'calls out the FIA' following McLaren controversy as new measures considered

An F1 team boss has called out the FIA to clarify what teams can and can't do within the technical regulations following controversy surrounding the flexible rear wing of the McLaren.

McLaren took the lead of the constructor standings for the first time since 2014 following Oscar Piastri's sensational victory at the Baku street circuit in Azerbaijan.

The Australian overtook pole sitter Charles Leclerc after the pitstop phase and put on a masterclass in defense to fend off the Ferrari driver and win the race.

Piastri's win has since been shrouded in controversy following onboard footage showing his car's rear wing flexing open on the straights without the aid of DRS.

Despite the FIA confirming the car was legal following the race they have since released a statement revealing they will look into the evidence and decide if they need to take action.

The F1 rule book has always been ambiguous with teams constantly looking to find loopholes, but one team boss thinks the FIA needs to get to the bottom of this particular issue ASAP.

According to a source from Autosport, one team boss said: “Aero elasticity has been a factor for many, many years now, and even if a wing passes the FIA test the regulations remain very clear - the component cannot be designed to flex.

“We rely on the FIA to say, okay, what are the boundaries of that? Of course, everything will flex to a certain degree, but what is acceptable and what is not?" they explained.

They added that even if the McLaren's flexible wing is eventually fully confirmed as legal, this kind of delay means other teams can't risk using valuable resources to do the same to their car.

“We're starting to see extremities be exploited again, and I think it's down to the FIA to decide, is that okay, in which case everybody will pile in or, as per the regulation, the way it's written, does that comply?" they added.

“There is a large scatter of who's doing what now, obviously with a lot of interest in the McLaren rear wing after Baku and there is performance in it – of course there is.

“That is why everyone is chasing it. But it's just knowing what is reasonable, and what's taking the p*ss.”
