Interesting no apparent change to the sidepods.
The floor received vortex generator treatment.
But the floor is still not as developed as the redbull. The holes in the side by the rear wheel are much simpler and the stay works in tension only to prevent buckling from low pressure, but it cannot prevent upward loads like the struts do under the redbull engine cover.
Merc is quite lethargic with updates compared to the other teams. Maybe their staff is too expensive and not worth their weight?
I disagree. I think this package was very cohesive and well thought-out from front to back. Touched on virtually every single area of the car and that middle section of the floor is now every bit as sophisticated as any other top team.
It’s the underfloor I’d love to see. Regardless, I think some people (not directing this at you) just want to see different side pods because it’s a visually dramatic change. Large bits of bodywork aren’t necessarily inherently worth huge chunks of time.
And there is still nothing to suggest that the side pods were the cause of any of the team’s issues. The aero porpoising has been cured since Barcelona. None of these upgrades were related to that issue or bottoming out. All downforce.
They’re just going to have to continue bringing downforce to the car to offset them running it higher than it was supposed to be in the tunnel.
I totally disagree with what you say about the sidepods. There is definetely a lot that suggests that these sidepods are a big reason for their problems.
There were three teams at the beginning of the season with "Micropods". Mercedes, Williams and McLaren. McLaren went away from that philosophy a few races ago. Now also Williams has left this path. They did not do that because these sidepods were advantageous and did not cause issues.
Next to the problems this design brings in relation to flexing of the floor(which was clearly proven by the addition of a second bracket in Canada)and its relation to porpoising, they obviously have realised in CFD and the windtunnel that these sidepods are not the way to go. Of course they must have a lot of disadvantages in terms of aerodynamics etc. otherwise they would not do such a huge change concept-wise.
With the bargeboards missing the front wheel wake hits the rear of the car, disturbing the airflow and also giving a drag penalty in comparison to the "big-sidepods" which are "pushing" the front-wheel wake away from the car, hitting the rear-tyres instead and reducing drag. Thats pretty obvious and was proven by CFD simulations in this forum. Even if some people here still doubt that, the performance and the problems of the cars were exactly what these CFD simulations suggested. In Mercedes case you also have the inlets going all the way down to the floor what takes away the possibility to create a lot of outwash and a pressurisation zone under the sidepod inlet. They try to compensate that with all these winglets and the massive wing they have in this area, but this also seems like a pretty draggy and less effective solution. Toto Wolfs comments in the first few races "we have to lose drag" and their problems regarding Topspeed were also exactly the problems to expect with CFD simulations like that. And Mercedes ongoing changes in that area support further supports this.
But anyway - at the end of the day all the teams now have gone in the opposite direction, leaving Mercedes the one and only team with these kind of sidepods. And that pretty much says everything. Especially in the era of the budget cap. Williams and McLaren would not have spent a lot of resources on changing the sidepods if they would not have been a source of their performance issues and the area they can improve the most. In the era of the budget cap, you do not change the sidepod-philosphy of your car completely if it is not the cause of any of your teams-issues.
