Mercedes F1 regulation change demands rejected by FIA

The Formula One 2023 season has been dominated by bickering over the new ground effect car regulations which came into effect this year. The intention of the FIA was to change the way cars produced the necessary downforce and make it easier for cars behind to follow more closely without destroying their tyres. Further it has made overtaking easier which has proven to be up around 50% on the 2021 season.

The cars have been fundamentally redesigned in what has been called the biggest change in car design regulations for a generation. Some teams met the challenge well whilst others produced cars that ‘porpoised’ or bounced significantly.

Since the fourth round in Imola Mercedes’ driver George Russell who is also a spokesperson for the Grand Prix Drivers’ Association together with his team boss Toto Wolff have been calling on the FIA to act on the grounds of safety to the drivers’ health.

Such was the bouncing of the Mercedes’ car in Baku, Lewis Hamilton struggled for around a minute to extricate himself from his W13 car having suffered extreme G-Forces from the bouncing on the bumpiest circuit of the season.



Since then the FIA have instigated a data collection exercise measuring all the cars for vertical forces the drivers have been suffering.

They have instigated an immediate fix starting at the next race in Belgium which tightens the regulation around how the plank under the car and the skids are secured to the chassis.

However, Mercedes have been advocating there should be a design change for 2023 that ensures the cars do not repeat the bouncing again.

Wolff has ‘evidence’ current car designs cause “brain damage”

An ensuing row broke out between primarily Mercedes and the other teams who felt it was Mercedes problem due to the design of their car. In recent races most teams.

Christian Horner recently observed that since Baku the bouncing effect has been barely noticeable on any of the cars.



Toto Wolff rejected this outright claiming the issue is track specific and may resurface later in the season.

“That (argument) doesn’t count because Silverstone,” said the Mercedes boss.

“Paul Ricard and Austria aren’t exactly tracks we bounce that much on anyway. I don’t want to come to Spa or some of the later races where the track isn’t as smooth as a conventional racetrack and we didn’t do anything about it. There is all this talk about lobbying in both directions, but what are we talking about here anyway?”

Mercedes asked the FIA to change the regulations for next years’ car designs without the agreement of the teams which they are only able to do on the grounds of safety, though 6 teams recently opposed this because it would be outside due process and questioned whether in fact it was a safety issue that would allow the FIA to act unilaterally.

FIA crafty new tyre regulations for 2023


Horner leading the group of 6 explained in Hungary, “It’s not just about the raising of the floor height, or the [diffuser] throat height, which can have an impact into components that you wish to even carry over for next year.”

“I think that there are other aspects regarding increasing the load test on the leading edge of the floor, for example.

“We don’t want to get into some aeroelastic race that, whilst the height of the floor is raised, the elasticity becomes the flavour of the day, and we all end up chasing wackier elastic concepts.

“I think it’s important that the whole package in its entirety is dealt with, rather than cherry picking single elements.”

Rumours began to abound over a legal challenge being brought against the FIA should they bend to Mercedes requests.



Aston Martin team principal Mike Krack hoped this would not be the case.

“I don’t think there will be a legal fight between the parties,” he said. I think we will find a solution as we have done with many things lately.”

Ferrari too were against any changes to the floor for next season.

“We are very late in the day to change cars for next year,” said racing director Laurent Mekies.

“Most of us will be already in the final stages of our programmes. It [porpoising] is pretty much a non problem now for quite a few races. So it will be rather awkward to impose a design change now.”

The proposals the teams were against included, included a raising of the floor edges 25mm and diffuser throat – something that will have a big impact on car design and how they generate downforce under the car. This could again see the cars displacing more ‘dirty’ air over the top of the car and making it hard to follow once again.



Yesterday representatives for the teams met with the F1 Technical Advisory Committee and an agreement has been reached.

The floor edges alone will be raised by just 15mm but the FIA refused to back Mercedes ideas in full.

Speaking to racing356 a philosophical Christian Horner commented.

”[15mm] is not as good as leaving it alone, [but] it’s not as bad as the 25mm that was originally [suggested]. It’s a compromise that we’re just going to have to incorporate for next year,” said Horner.

“We’ll just have to deal with it and find a solution. That’s what we’ve been good at over the years, and we’ll just have to do that with this challenge.”

Red Bull’s chief technical engineer Adrian Newey cut his F1 design teeth on ground effect cars and understands the aerodynamics better than most.

It’s unclear ho the regulation will affect the teams performance but Mercedes are hoping it brings some of their main rivals back towards them.

Yet if Mercedes new W14 for 2023 is off the Red Bull pace again, maybe it will be Newey and Horner who have the last laugh.

  1. So FIA again show that they do not have a stiff enough backbone. Ann Rao must have put up one hell of a fight. That’s why a 15 mm increase in ride height has been conceded. Mercedes (and of course Toto) must have known that 15 mm must be quite enough, so they drove a clever bargain insisting on 25 mm. So Toto wins again with his deception. Properly speaking, FIA should have thrown out Toto’s demand in TOTO. Instead, they have made a fool of the other teams.
    MB have already recovered to the point of talking about competing with Ferrari and winning races. Now their aim is to make the Merc a rocket ship again like the earlier years and gift the drama queen paper champ an eighth title. Their lust for it is so great that they will not stop pushing towards it by any means, more foul than fair.
    No dignity as Ferrai said. Revolting!

  2. Blimey Vij, you really hate Lewis and Mercedes. Horners an egotist too. Seems like there’s clearly cheating and lies on both sides!

  4. Mercedes, your design flawed with zero sidepods..this create unbalance downforce between ground effects and the less planform area of the car. As usual, when merc failed to do a good job, they whined and dined under the pretext of safety with equally good drama acting. FIA is giving merc too much attention and this is bringing the sports into disrepute and conflict of interest. Ross Brawn is surprisingly quite for his brainchild concepts in which he failed to anticipate the occurence of porpoising. I know his time in F1 is up. But sucking up to merc? I rather watch NHRA, midjets, Indycar…anything not affiliated with fia.

  5. As usual Mercedes is going to do everything they can to keep the stupid hybrids in the cars while the other teams want the V10 what else is new , even the drivers are saying that they want the V10 and I agree with ALL OF THE drivers , this includes the one that’s been very vocal about bringing back the V10 Lewis Hamilton that’s right and Abu Dhabi ( When Alonzo brought his own car in 2020 ) is the one that commented to the TV people he love the sound of that V10 so what are we waiting for here folks .

    • Sure, it happens… Drivers are not made of steel – which also brakes, occasionally.
      Making drivers suffer unnecessarily is “blood sport” and those belong to the Roman empire times. They are Gladiators, but not in that respect.

  7. This is totally crazy and unnecessary. If cars are bouncing to the point of pain for the drivers on some tracks and on some don’t….then there’s a FIA problem with Organizers of the races and facilities that are not up to standard.
    That’s one point, second: What happened with Teams solidarity and integrity of the Formula 1 sport as a whole?
    The constant bickering and accusations, animosity and “media wars” are not worthy of Teams that in “good old days” were not that unison, another – but sorted out most of problems among themselves.
    Today, whole thing reminds me of Kindergarten where Team Principals run to FIS regulators for every single “little” thing.! Nobody wants to watch bunch of bickering “fishwiives” + man up and let’s see who is fastest… That should be and is Essence of Formula 1.
