Has the front wing been tweaked where it says "NAS" on the driver's left, and "PET" on the driver's right? IE, upper most winglets, towards the outside?

Yes, Ted mentioned it during the sky coverage.

One thing you can say for sure is that the rims primary purpose is for both convective cooling and radiant cooling.
The black paint is a give-away sign.

RedBull also have black inner rims donkey's years ago i believe.

Had they have multiple little extrusions how could they maintain the pressure inside the tyre or maybe they have a double decker inner rim wheel?

The temperature variations of the tyre affect the tyre life more than the pressure. The pressure changes are minimal and are pretty much a result of the tyre temperature and wheel compression.

The wheels seem to have pattern of hundreds of small pyramids in the order of a few millimetres tall. I guess that the pyramids are the best compromise they can get in creating "fins" on the wheels and keeping the manufacturing process of the wheel, which is forging, the same. A more conventional fin shape would be more effective at heat loss but it would require either a different manufacturing process such as casting, or it would require a separate part with the fins machined in to be bolted on to the inner face of the wheel; which is against the rules. So, overall I think this is Mercedes' best interpretation of finned inner wheels.

Isn´t the engine-cover-hole a bit smaller then in Hungary? Looked to me Rosberg ran a very small "RBR-hole"

[SectorOne]

Yup found it, different engine cover. Or at least the exit hole is different i.e. smaller opening.

... so these small pyramids are holes at the surface of the inner rim (towards the hub) and their peaks are towards the gap to the tyre? (sorry if I can't be understood, as you saw english isn't my first language ... maybe you could draw a small picture in order to figure it out )

Mercedes changed the diffuser? before there was an air outlet above the center of the diffuser and in singapore this is closed

Yes! Good spot!
But they changed it in Spa: http://img3.auto-motor-und-sport.de/Mer ... 716380.jpg
Also in Monza: http://img3.auto-motor-und-sport.de/Mer ... 716380.jpg

thank you I haven't seen it before! what's the gain with this change?

Talking about the Merc rims, I noticed that Lewis tyres cooled under braking off the start line, while Massa's heated up.
Hmmmmmmmmmmm!

Probably the difference between front and rear tyres under braking.

No, off the start line Massa's rears were relatively cool compared to Lewis, then at the first corner, you could see Massa's rears heat up as he braked. At that precise moment, strangely, Lewis red hot tyres cooled down.

I posted almost immediately I observed it during the race, so my observation might be off mark, but I doubt that it is.
Does anyone have the recording?
