Merc’s self-described list of upgrades captured here.

Nice to get confirmation that the wishbone change was for better sidepod cooling. Don't think people will stop talking about anti-dive though...

Probably need to see a top down comparison rather than a front on really to make any kind of judgement as to whether the kinematics will change drastically.

It maybe. Do you think they list everything on that sheet.
We've changed it for cooling. PS, it is also a bit of anti-dive as a side effect.

They are avoiding any suspicions of the suspension used primalarily for aerodynamic reasons is what.

As most have predicted the side pod undercut is used to help the floor edge:

As per the FIA explanation when it came to the revised sidepods, the description read that it is “to improve flow to the floor edge, which results in more floor load and also proved flow to the rear corner.”

I think I mentioned this about the RB a long while ago. That the angle of the upper wishbone triangle was perfectly aligned with the floor leading edge as if they were using it like a fairing to turn air down towards the floor LE (the nosecone is generating some upwash)

The front wishbones treat the air for everything behind it, so it’s understandable they would have to change substantially with a big change of concept.

The anti-dive thing still blows my mind and makes my head hurt. I can open up racing chassis engineering books from the 1970s and it’s talked about in depth and they have understood aero pitch sensitivity from day 1 - most of the early aerodynamicists came from aerospace anyway, but Steve Nichols has talked about it on the 1980s cars, active suspension was obviously a solution, Willem Toet as mentioned earlier gave examples, etc. NASCAR and Indy Car (before the chassis became spec) used asymmetrical anti-dive to help the cars handle on the ovals, every production car for just about ever has an element of anti-dive. It’s rudimentary stuff and the implication that Mercedes forgot something that current engineer’s grandparent’s age knew is a bit silly. There is no silver bullet on any of this.

The problem is just about anyone can create a youtube or twitter channel and parrot something they just learned about but don’f fully understand, and the media just eats it up because they don’t know ant better and because it “kinda sorta sounds plausible / smart”.

Wait until people find out the Lotus 72 used a lot of anti-dive (and squat) to control aeropitch sensitivity to help it win races starting in 1970.

Maybe Colin Chapman, Tony Rudd, and Maurice Phillipe were time travelers and discovered anti-dive on Twitter and reddit.

The new whishbone mount setup.
Neat to see the part number. Maybe 2023 Chassis 01 - Part 2161 Number 2?

[Farnborough]

Has it a date code too ? 04-11 perhaps? 11th April manufacturing maybe.

Coded for traceability, lifing, inspection, cost cap consideration all likely.

Is that a heave spring/damper in centre background, possibly with set of Belleville spring medium in there ?

Cooling flow is an aerodynamic effect, is it not?
