Omnicorse.it on Merc front suspension tests:

Reading this it seems Mercedes are looking at a FRIC-esque setup on the W07. However, not front and rear connected, but only on each axle.
I'm wondering how this would circumvent the regulation that frics is an aero aide? By front being independent of the rear?

[Sevach]

Left and Right sides of the same axle are already connected by a revolutionary tecnology called anti-roll bar.

Right now i can't say a thing about what would be the benefits of this system either replacing or working in tandem with the roll bar.

Not sure if this is the correct thread to post these questions I've wanted to ask for a long time now, (apologies if this is very straightforward for those who knows how suspensions work)

1) How do Mercedes have very little amount of dive on their front suspension when braking,
2) Lots of suspension travel on the loaded side when going over kerbs in corners, but very minimal on the unloaded (tyre touching kerb)
3) And very minimal bounce when car is released off the jacks during pitstops?

Reference videos:
1: https://streamable.com/2vzc (can't see any movement on the pushrod, etc.)
2: https://streamable.com/tnxr
3: https://streamable.com/eetw (watching the ground shadow near the front left wheel, doesn't seem like it bounced at all)

I'm not sure about the thread either, much less so about me being spot on in engineering terms, but I'd say:

1) and 3) mean stiff springs and/or shocks, while 2) means an unusually soft anti-roll bar.

Looks to me like they connect the left and right front suspension the same way Koenisgsegg run that "triplex" suspension:

This is the correct thread since the topic you put up handles the hardware of the car. On rare occasion, we might decide to split off the topic into a seperate thread. This generally only happens if a particular part of the car completely dominates the car thread. We are a long shot away from that, so don't worry.

I'm convinced that merc has something in their suspension system that no other team has. The lack of roll, dive or squat while remaining able to take curbs better than any other car is something that has puzzled me this and last season.

A few races ago the merc drivers were able to take a line through a few succeeding corners that no other driver could do simply by virtue of their car riding the curbs much better than anybody else.

How exactly did the FIA ban FRIC suspension? Does anybody have the actual wording of that regulation?

I am convinced of that too. I don't have any useable knowledge whatsoever on suspension. However, I tried to look for pictures of their front suspension system and it really stroke me that on almost every picture they have a cover on the parts inside the chassis. They are apparently very keen to keep it hidden.

Last weekend however, they tried out their supposedly S-duct device, which meant they had to remove the cover:

Here a pic that shows Merc has a interconnected suspension. You can see the hydraulic hoses hooked up to keep pressure in the system.

(Apologies if I got my facts wrong on how stiff/soft the dampers/springs are while explaining below)

But won't stiff springs mean less suspension travel though? Unless it's a very stiff heave/third spring but very soft corner springs?
Though I'm still confused how does the inside suspension not get much compression, meaning stiff compression dampers but the outer get's so rebounded quickly, meaning less soft rebound?
What puzzles me is that, isn't rebound supposed to be stiffer than bump/compression?

Another video illustrating that characteristic: https://streamable.com/h0f0

I think it has like you said, very very soft anti roll bars too, it does have roll I think, judging from the suspension oscillating up and down

Another video showing the bounce-less pitstop, with very little vertical suspension travel, but still manages to do all characteristics above (roll, bump) with more travel, and bounces at kerbs except at pitstop?

I refer you to my previous comment. That design allows for compression on one side but never both at the same time. Which would explain why they can brake heavily with little to no compression, but ride curbs all day long.
