The mechanism is not different, it is very similar.

The cylinder alone is not the mechanism my friend.

Huh? The basic prinpicle and motion are the same. Just the parts are looking a bit differently. So yes: basically the same as last year, but no: freshly made and redesigned parts.

So all F1 wheel hubs are the same then? Since the principle of motion is the same and the parts only look a bit different? Gotchya! Hehe

So apparently the car still bounces harshly. Lewis points out the rear is the problem. Now I'm looking at the pushrod and it's just crazy acute the angle it makes. Mercedes still haven't quite figured out how to make good rear suspensions.

Aston Martin looks way better than Merc in terms of jumping, not sure if the issue is just suspension.

Car still not an all rounder. Mercedes still haven't quite cracked the new code since the floor edges were cut in 2021. Funadmental suspension and floor aero issues since then. They always used bandaids to get around their deficiencies in these areas!

Exactly the same as last year. Absolutely abysmal performance in high speed cornering.
They're really going to need to get on top of that and sharp.

Hence why Russell and co were pleading for active suspension in 2022. Thanks to the ban of utilizing hydraulic actuation that really put a number on them for sure

Hamilton in an interview essentially said it’s 3 years running now they have a garbage car that is not following other successful concepts.

The move to Ferrari looks smarter by the day.

Was the ban of hydraulic suspension due to cost cutting or to reign in Mercedes.

If they keep making a floor, this being their third in a row on W15, that gives very peaky accumilation curve, and particularly the need to only be so low to ground, then mitigation measures such as the call for various suspension system, will look logical.
The other teams have figured it out, within these rules, MB needs to understand what they've made in this iteration to get anywhere.

Mercedes suspects a "fundamental problem" affecting the car's performance in high-speed corners after the Saudi Arabia race.

There is a possibility that this is a design issue rather than a settings issue. Currently, all research is focused on this.




The design problem is still there since W13
It could mean the older car that was faster in the simulator is indeed faster but they have missed something for 3 consecutive years
First it was ride height, sidepods , suspensions floor and now what?

The greatness of Mercedes F1 technical team is a thing of the past and this keeps showing under these regs.
I wonder if this “fundamental problem” has anything to do with their peculiar rear push rod.

It looks competent in design, high leverage and likely to incorporate need for careful optimisation of load path sizing, more for durability than anything else.
We've not seen detail image of arrangement hidden under rear covers to make decent comments in accurate assessment, but unless they say specifically that from their knowledge, then it doesn't appear to be root cause.
There's plenty of experience with highly loaded suspension design in F1 and other fields to cover this off in my view.

They appear to have lost control of floor understanding/simulations/reality as that repeating cycle into this W15 shouldn't happen.

This rear suspension doesn't appear to be getting into problem within AM chassis and aero architecture, also pointing to something they are struggling with in their own design. More images of W15 details would be welcome in this thread to further discussion.
