Actually I don't understand this "no-gills-at-any-cost" hysteria.
This is supposed to be a technical forum, but there's not a trace of technical argument.

First of all I think those gills are for the Malaysia configuration but they may like to test them on Friday.
Second, the gills are in the same region and very near to the exhaust exit which has by itself a significantly larger effect on laminar flow around the body. So in comparison to last year's ducted exhaust their influence is perhaps less important and, who knows, may even contribute to channeling the exhaust plume towards the desired direction.

Bit stupid question...but what the hell...
Can someone please explain me why it will work only in Quali's and not in race?

In Quali you can use DRS everywhere, in race you can use DRS only when overtaking. So, the effect is smaller. This is when Fduct is triggered by DRS only.

I think i spotted a new detail. Check that aero "extension" on the sitepod. Dont think i have seen those during testing. If someone has a proper english word for it, feel free to inform me.

You could be very correct about them being for swealtering Malaysia.

The air coming above the sidepods and contacting the exhaust flow is without a doubt cleaner flowing air and these gills appear to be in contact with not only that air but also air coming around the sidepods. I don't believe the air coming from the gills could in anyway affect the exhaust which is moving at an already high velocity, but I don't think it would be out of the realm of possible that the exhaust could aid the air coming from the gills 'charging' it to the back end lessening the slowing effect that air would normally have.

That's the attachment point and support for the vertical turning vane or whatever it is called.

@Dragonfly

Oooops, yes. You are right. I kinda feel stupid now. heh.

[Dragonfly]

Nothing to worry about. I think it's just the tension building up in everyone the less time remains to the start

[Pierce89]

I explained how simple it would be to operate the FWstalling device via DRS some pages back and someone else mentioned that it would be legal due to the secondary nature of the operation.
Charlie Whiting would have almost no grounds to ban the system and the others teams whofeel they may have an advantage otherwise, would notbother to protestit but simply copy it.
The aim of the Fw stalling is to restore balance to the (down)force and from now it shall be called the Vader wing

There is no safety ground that canbe used to ban it since it ultimately enhances safety through maintaining aerodynaic balance.

As for the shark gills... I can't subscribe to the idea that these would degrade aero performance without seeing the fluid flow simulations. we have no idea of the pressure driving the air at exit nor how the gills are shaped on the underside to shape exit air flow.

Grounds for banning: DRS driver activated+F-duct DRS triggered=F-Duct is driver activated.

[The FOZ]

What I'm ultimately wondering is if the front wing does only work with DRS, but also works passively once a certain pressure is reached. If I had to guess, I would say yes, absolutely. This would yield some straight line speed during a race which is really where it's needed.

Perhaps not. A t-junction between RW air, nose hole air, and FW slot air could function as a sort of air pressure logic gate, with flow ordinarily going to the rear wing. When DRS is active, the flow reverses, anor at least decreases enough that nose hole air goes to the FW slots. Then again, sufficient pressure could blow the FW slots AND the nose cone hole...doing I have no clue what.

A series of such pressure gates could produce a number of these effects, changing airflow over several areas of the car.

Bloody clever...RB again shows his capacity to foster innovation!

[King Six]

I'd like to see just how Mercedes have created some sort of duct from the rear wing travelling through the entire car to the front wing. Surely it would've been visible somewhere by now when the engine cover was taken off or something?

[Fredy4]

It would go along the bottom, I'd think the only place you would see a hose (as it were) it with the nose cone off.

For your argument to work, it would have to be directly activated by the driver. This unit is indirectly activated by a legal device, the DRS, for which there is no rule stating a secondary purpose is not allowed.

So you're saying flow would be constant to the rear wing and only controlled via pressure differences reached between the rear wing with DRS active and/or with certain reached pressures at the front nose inlet say above 'X' predetermined speed or pressure. This would allow the system to work both passively at the front and with DRS. You're right though, the pressure switching mechanism(s) would get complicated

[dren]

You can see the plate along the side that would rotate with the wing, opening a path.

@Scarbs

Do you know for sure the flow is entering in and going to the front for sure, or is this just a guess? It could collect quite a bit of high pressure air from the top side upwash of the lower wing flap.
