Can you please just post a link to the 5k+ resolution photos?

Yes, no problem.

Hi guys, I have been reading this forum for quite a long time but have never posted anything. So this is my firts time

I've heard news about McLaren being concerned with the excesive fuel consumption. Has anyone else heard it too?
Paddy Lowe said a couple of days ago that the 100kg fuel limit was "sometimes very frustrating".
If that's not the case with other engines, we could see Merc-powered cars winning quali by quite a margine and then having to go slower than the competition in the race. To me it seems Merc concentrated more on power while Ferrari's philosophy is more about being smooth and fuel saving. In this case, at least in the early part of the season, aerodynamics would be much less important (that's what Newey said). What do you think?

Can you provide a source for Mclaren's fuel worries please?

I think he's talking about the general feeling that the drag from McLaren's suspension will make them more concerned about fuel. I haven't seen anything from McLaren themselves about it.

Gurney on hot air exit.





Probably for helping to extract hot air, or even to direct it upward.

[Thunder]

They had that yesterday already.

[Owen.C93]

So does Mercedes.

Is the hot air exhaust gurney more to create low pressure to draw out hot air? Or aero benefit to the general theme of creating big areas of low pressure in that part of the car, along with suspension blinds, monkey seat, etc.

[Owen.C93]

Just helps with cooling, they ran it in 2010 too. Here's an image showing the gurney tab and a decent view of the rear wishbones. They are pretty thick.

McLaren's pull rod looks a lot thicker than it has done in previous years, and a lot thicker than other cars. I wonder if that's a side effect of the louvre suspension increasing loads?

Was just thinking the same while I checked out that picture. Like I've said before, I'm pretty sure there's more than aero things going on with those bell shaped components. Convinced of some geo/ride height adjustments with various loadings/aero pressure, etc. May have an impact on other parts, hence thicker pull rod??

Someone with more tech knowledge than me might be able to embellish my ramblings?

Can anyone tell me what the inlet in the red circle is and the bulge in the green circle?
