Red Bull agreed to make a change to their RB20 ahead of this weekend’s F1 𓃲United States Grand Prix after talks with the FIA.

Here are the key 🉐questions answered about the technic𝕴al controversy in Texas.

How did the controversy begin?

F1 teams complained about an unnamed ri💦val exploiting a way to lift the h𒁏eight of its T-tray. Reportedly, they found out via open-sourced FIA servers from the Singapore Grand Prix.

Red Bull were the cause of concern, it emerged.

What do the rules allow?

Ever💞y F1 car is🌞 left in parc ferme between qualifying and the grand prix. No major set-up change is allowed. Only the front wing, using existing parts, can be tweaked.

There🌊 is no evidence to suggest Red Bull broke any rule.

What was Red Bull’s response?

The F1 constructors’ champions confirmed about tꦕhe ‘T-tray’ or ‘bib’: "Yes it exists although it is inaccessib🦂le once the car is fully assembled and ready to run.

"In the numerous correspondence🐎 we have with the FIA, this part came up and we have agreed a plan going forward."

In other words, Red Bull confirmed the presence of the device but insis⭕ts they are not able to utilise iꦇt in a way that would break any rule.

Red Bull and 🔯the FIA have made agreed-upon changes.

Have the FIA made changes?

An FIA stateꦓment confirmed: “Any adju♒stment to the front bib clearance during parc ferme conditions is strictly prohibited by the regulations.

“While we have not received any indication of any team employing such a system, the FIA remains vigilant in our ongoing efforts to enhan♋ce the policing of the sport.

“As part of this, we have implemented🐼 procedural adjustments to ensure that 🐻front bib clearance cannot be easily modified.

“In some cases, this may involve the application of a seal to provide further assur꧟ance of compliance.”

Why is ride height important?

F1 teams try t꧂o ru👍n their car as low to the ground as possible. But it’s a balance. Go too low, and you damage the underside plank and lose the performance that you’re chasing.

Lowe꧂ring the car is especially important for qualifying because one-lap speed is the priority. In the grand prix, teams run their car higher for a variety of𓆏 reasons.

This means that, bec💃ause changes are not permittedꦐ between qualifying and the grand prix, teams must decide on the perfect balance beforehand.

Are McLaren unhappy?

McLaren’s Lando Norris is 𒅌52 points behind Red Bull’s championship leader Max Verstappen in the battle for the F1 title.

Norris said: "If it has been helping them, if they have been utilising it in 🅘a way people think 🐈they have, maybe it will shift in our direction.

"But, whe✤n you talk about things like that, they won't have got several pole positions or🌱 wins because if that device.

"I don't think it will change anything in the scheme of things. Maybe at certain qualifyings when it has been split by hundredths or thousandths, you might say🌞 'OK maybe this has helped in this direction or that direction'."

Did the device help Red Bull performance?

Red Bull’s star man Max Verstappen insisted the🅺 device has no impact on performance.

He added, correctly, that details of the devi♐ce were available to rival F1 teams via FIA servers. He insisted this proves Red Bull were not seeking an unfair advantage.

Verstappen sai𓄧d: “It's ope𝓡n source, right? Everyone can see it.

"For us, it was jus✅t꧑ an easy tool when the parts were off that it was easy to adjust. But once the whole car is built together, you can't touch it. So, for us, it doesn't change…

"When I read it, I was thinking about 'are there other teams doing it?' And then I found out it was related to our team. We never even mentioned it in the 🌠briefings, so it's just an easier tool to adjust stuff."

Did Lewis Hamilton defend Red Bull?

“Our sport is all about innovation,” Hamilton t🔜old Sky Sports F1.

“Red Bul🎃l have bไeen the leaders and they’ve innovated.

“Ultimately all the teams lookꦰ at the rules and try to find hoಌw to massage those rules and get the most out of it, even if it’s just over the edge a little bit.

“You just need to continue to evolve and be b💞etter policed.

“At the end of the day they did a better job. God knows how long they’ve had that, and they’ve been winning championships. ๊Maybe that stops now… I don’t think that♕’s the one thing that’s going to stop them.”
