Could it be called R30 a 'cabrio' now? Was this earlier?

Look at the right side rear yellow 'bulb'. What could be this?

Interesting that they seem to be sticking to their usual wing rather than their low-df/low-drag front wing configuration in Canada

[Carlo's]

Their rear wing is also new raymondu.

[raymondu999]

Yeap. But I meant the front wing sorry

[Carlo's]

Probably now with f-duct they can riding with more downforce. They admitted in Canada that the level of downforce is too low with those wings.

[Blackout]

And in the last Gp they brought (with the new diffuser and RW) a modified bodywork, with probably modified exhausts and suspensions (upper photo)

Am I looking at that image wrong?

It looks like their F-Duct blown slot is only in the de-restricted central section of the RW.

OR is that a conventional blown slot, and the F-Duct blowing slot is elsewhere?

Oh wait, I think I see a very feint line on the black lower element which might be the F-Duct blown slot.

Interesting that McLaren have theirs on the upper element?

EDIT: The slot on the upper element is indeed a conventional blown slot AND the connection from the airbox is going to the lower element as per the Sauber. That'll teach me to read only the most recent post!

In F-Ducts, upper elements are harder to blow, but easier to re-attach the air once they arnt blown anymore. However the lower elements blow easier, but they are harder to re attach the air flow after being blown, thus creating downforce later.

The first is an examole of what McLaren, Ferarri and Red Bull have, the second is what BMW Sauber, Force India and now Renault have.

One other thing about F-Ducts, the McLaren solution is much more costly to design, manufacture and implement. But the Force India and BMW Sauber versions cost about 10 times less to design, manufacture and implement. Rumors that the Force India solution cost arround $1.2million to get onto their cars, and the BMW Sauber version is rumored to cost not that much more.

So in conclusion Renault have gone with the easiers and most cost effective solution that has its own pitfalls with regaurds to re-attaching airflow.

Wow, lots of info there! Thanks for the concise reply ESP.

I didn't hear you get another name check in the FP sessions today though! Should I listen out for one tomorrow?

[747heavy]

not sure, but to me it looks like, that Sauber is blowing the flap/upper element, not the main plane ala Renault. Looks more like a McLaren solution to me.
