So they're using the lower roll-hoop intake for cooling the G-box not the Kers

This car is tunneltastic!

I wonder why that wing is labeled "Race". You can't change a wing during park fermé:

n) The aerodynamic set up of the front wing may be adjusted using the existing parts. No parts may be added, removed or replaced.

I think it basically means, "fit after fp3"

Internal winglets (they might be there since a while, but I've never noticed them)

Weird, I can't imagine these would actually directly produce downforce, after all, if you create high pressure above one of these wings, you're going to be also creating high pressure under the engine cover's surface, and cancelling that out (people who actually know about aero correct me if this intuition is bullshit).

So what I'm wondering is if the effect is two fold...
1) they get a high pressure zone above it that they can use to drive air through some air outlet to drive another aero device elsewhere.
2) they get a low pressure zone below it, which can be used to drive the DRD – RBR's DRD is unique in that it doesn't have the weird monkey seat to create the low pressure zone. Maybe these are used in creating that.

Or they are just there to let the air (high presure) move away from under the engine cover faster.
Hence creating less drag

Sure, that was reason 1... But there's still a low pressure area created too, which you would expect there to be a reason for... or at least a useage of it since it gets created "by accident" (assuming it does, which I doubt with newey at the helm).

The effect of the pressure differential acts only on the wing.

They're located here below the N of RENAULT

Hmm? Why would it not have an effect on the engine cover too, which has high pressure beneath it, and low pressure above it.

Okay, so that seems to confirm that the upper winglet generates high pressure above it, and helps force air out of the cooling hole there. The lower one, is that maybe generating high pressure beneath it, and helping to force air out, and into the tunnel?
