Red Bull's ride height device is under control, claims FIA's Nikolas Tombazis

Following the recent technical controversy, FIA's head of single seaters Nikolas Tombazis has insisted that Red Bull's ride height device is under control and the governing body considers the matter as a "non-story".

During the build-up to last weekend's United States Grand Prix, it emerged that Red Bull might have been using a device that could enable the reigning champion team to advantageously change the car's ride height via the 'bib' at the front of the floor when in restricted 'parc ferme' conditions, which would be in breach of the sport's regulations.

The Milton Keynes-bas outfit confirmed just ahead of the practice day in Texas that they had agreed a plan with the FIA to make alterations to their car following talks with the sport's governing body.

FIA's head of single seaters Nikolas Tombazis said there was no evidence Red Bull had done anything illegal and believes that the governing body has put the necessary measurement into place to make sure that any attempt to do so in the future will be easily detected.

"At the previous race, it was pointed out to us that certain designs could allow a change of the height of the front of the car, which some people call a bib, in parc ferme," Tombazis told Sky Sports.

"We didn't have any indication or any proof that anybody was doing something like that, that would be clearly illegal under parc ferme regulations.

"But as I said, we didn't have any clear indication that somebody was doing such a thing, so we said from this race onwards, then there must be no possibility to do such a thing at all.

"So if a team has a design that would allow a quick change of that height, then it had to be sealed so they could not have access in parc ferme. I think all teams have adhered to that, and as far as we're concerned, that's reasonably under control."

Asked if the controversy is now a non-story, he added: "I think it's certainly not a story from now on. I think we've done all that's needed to stop there being any accusations, and then of course it is a tight championship, and people get rather excited about each other's cars.

"So we can't definitively close the previous races or any insinuations between teams in a very competitive environment, but in the present situation, we believe it's a non-story, yes," concluded Tombazis.
