Cockpit air exit

I think that´s the secret of the letterbox!!!

Those outlets has been there for years.

Hmmm.... I do not remember seeing this before.

Any idea what it is used for? Purpose?

Could that be the exist of air collected at the slot in the hump of the front wing? Would this add any value, advantage?

Based on the pointed elliptical shape of the exhaust, this must be Newey's latest innovation to be copied by every other team

But, in all seriousness, it must be an exhaust to relieve the high(?) pressure build up in the cockpit. This could then bring down the flow passing over the cockpit, bringing it tighter for better flow to the airbox and the rest of the body.

Yes that´s the effect what the letterbox is made for. To calm the flow over the cockpit. Because open parts are for aerodynamic isn´t helpful.

Apologies for the totally random site. I don't have an online image account and this was the first thing that came to mind to get my thoughts on here.

Also, an added benefit is to add energized flow over the sidepods. Seems like a simple enough modification, I wonder why this wasn't as prevalent on 2011 cars?

This construction is simple but genius. So the secret about the letterbox is covered up! I think it isn´t possible to copy that in short time...

Those outlets were there on 2011 cars ... also 2010.

Those outlets are in f1 for years...

And why is the carbon fibre different here, again ?

I agree, I think the thinness of the letterbox betrays the fact that the volume flow rate through there is much higher and more direct than placing a hole in the front of the nose that will lose more energy by the time it gets to the cockpit.

Exhaust blowing discussions have their own little debating wonderland.

Are they testing the latters's flexibility ?
