Piastri accuses Red Bull of 'clearly breaking' F1 rules

Oscar Piastri has suggested Red Bull's ability to secretly alter the ride height of its car between qualifying and a grand prix “clearly” breaches F1 regulations.

On the build-up to the US Grand Prix from Austin, Texas, a report emerged that a team has been making use of a system to adjust the front-bib clearance of its car.

It was soon revealed that Red Bull was the team utilising the device - however the reigning world champions have confirmed it has been in discussion with the FIA regarding the matter and will make changes to its challenger.

Red Bull is currently embroiled in a title fight with McLaren, with the latter leading the constructors' championship by 41 points.

Exploring the limits of the technical regulations is commonplace in F1 - but Piastri has suggested the Red Bull device goes too far.

“I didn't know that Red Bull admitted to it,” Piastri told media including RacingNew365. “It's not really for me to get involved in. I don't really know much about it.

“We’re obviously pushing the boundaries of the technical regulations, everyone is. 

“It’s what makes F1, F1 - but from what I've heard and been told, something like this is not pushing the boundaries. It's clearly breaking them.”

Piastri's team-mate Lando Norris voiced hope that the discovery of the system could help solidify McLaren's position at the head of the pecking order.

While Norris played down the significance of the device, Piastri asserted it can only be considered illegal by the FIA.

“I haven’t heard which car it’s on, if it’s on any car - obviously there are reports of it,” he said.

“If it is something that's being used, it’s clearly not been pushing the boundaries. It’s out of the grey area and into the black area.”
