Mercedes W14

[RZS10]

One could use a similar approach i took when i tried to determine wheelbases a few years back to get ratios between the wheelbase and the cockpit/driver position, could also do that for the wheelbases in general using known lengths as reference ... it would give a decent enough result to verify it one way or the other and to check whether the cockpit was moved from the W13 to the W14 where the W13 was at the max. wheelbase allowed (judging by the markings in their pits in testing).

I basically go to the centreline of the car by estimating the axle on both wheels, half distance -> middle of the car, so there's very little error when marking something like the front end of the halo or the airbox intake.



I got ~0,19 for the ratio (front axle to forwardmost point on the halo)/wheelbase and ~0,48 for (airbox intake to front axle)/wheelbase for both the W13 and W14.

In pixels that was
W13: 229/1202 and 580/1202
W14: 219/1147 and 550/1147

Based on that i'd say that the positioning of the tub is the same or at least very very similar to last year, as the differences in the result are easily within the margin of error (and a change of something like 5cm would be the equivalent of ~16 pixels)

What is this??? :O

It’s 100% made-up nonsense, like everything that comes from that site.

At 0:39-0.41 there is weird wobbling, is it because of camera? Playback speed 0.25.

No idea on the credibility of the source

Zero credibility. The daily mail is more insightful.

That is pretty odd. It does look like its camera shaking, and I was looking at the brake ducts relative to the rear engine cover and couldnt see any movement, but then I noticed the upper FIA camera mounts werent moving with the rest of the frames. If it was the camera mounting (such as a go-pro on suction mount) then surely those FIA cameras/fins would also be moving with the rest of the shot.

It could be tire vibrations. The full wet tread block is almost like a dirt bike tire and you get a lot of vibration on pavement with them.

Probably this wobbling is the "source" for rumors about broken suspensions and weak bodywork

It's probably just the whole mount that's moving -fia cameras and all.

Maybe, but you can see in some of the footage (taken from trackside) that the rear wing is wobbling ( at 44 seconds and 53 seconds and at 55 seconds for example )

Regarding posting stuff from thejudge13... this is from the opening post in the thread, still applies:

This is the official Mercedes W14 car thread. The thread has been created to facilitate discussion specifically about the W14 car.

Please, ONLY discuss technical items of this car. Refrain from speculation.

General discussion about the team, its drivers and performance can be posted in the team thread.

Livery discussion also belongs in the 2023 Mercedes-AMG Petronas F1 Team thread

Here the wobbling slowmo looks like the go pro high fov distorsion compoined my the camera shaking

Overall I think at this stage there is so very little data/video to go on that it's pointless to try armchair analyse and any worry is premature. Lets see the first run in testing and be positive that all is well!

I said from trackside cameras (

(taken from trackside) that the rear wing is wobbling ( at 44 seconds and 53 seconds and at 55 seconds for example )

Even from the go-pro mounted camera, you have to ask what is causing the camera to wobble?

My belief is that it's coming from the wet tire tread block.

Loving all the pretesting speculation about the cars So many opinions and guesses, some evidence based and some not, some backed by expertise some not, it is great fun.

Not wanting to restart the sidepod argument but I grabbed an image presented by someone else, sorry I forget who, and marked (crudely) & measured the width (on the photo) of the pods in a couple of spots. The new pods appear to be narrower at the widest point but wider further back. so the W14 pods are both wider and narrower than the W13

FYI I have little/no expertise in aerodynamics or physics or engineering so I'm quite happy to trust that Mercedes have employed people with expertise in these disciplines who have done their best to produce the fastest car they can.
No one on this forum will know whether they have succeeded until the end of qualifying at race weekend 1, but keep going with the speculation...it is great fun.

This information is from F1s own website and Marc Hughes :

https://postimages.org/

I checked this to make sure I wasn't mistaken, although I was sure because it was said so many times. The driver's position and sidepods were further back on the Mercedes than on Ferrari and Red Bull. The engine was moved further back especially for this. As I said - was explained 2022 umpteen times by all experts whether Hughes, Piola and how they are called all. And I believe that they know a little more precisely, after all, they are standing next to the cars.

Great find Andi, and it also shows how far back and low the Merc sidepods were last year. They are certainly further up this year in both axes.

Are they though? Ill use this photo from Wogx..

If anything they look marginally further back. After reading the positioning of the sidepods I actually looked back at the 2022 car thread and checked where the other teams side pods began. All of them except Mercedes start infront of the monoque/steering wheel with the exception of Alpine:

Its the same this year, everyones sidepods start inline with the steering wheel/front of Halo:

Again, Mercedes is the odd one out.

Now I know those are just the pre-testing renders for everyone, but it wont be too far off.

I really do wonder why Mercedes pods start so far back. Almost in line of the drivers face

One pic you can see both front wheels. The other you only see 1 front wheel. The perspective is different so both cars are not essy to compare.
I don't have an opinion on this. I don't even think it matters much. But it stands to reason merc will have a longer tub if they need to carry the same amount of fuel as the others with a norrower tank that males way for the cooling systems. There was a pic with the naked tub on the ground.
