There is strange triangle shape at the upper element end of the rear wing.

do you mean triangle cut-outs ?

it could be to improve brakes cooling.

Looks like an F2002 Ferrari frontwing endplate. Or somesuch car. But i remember a v-cutout in that endplate as well.

Look carefully at the middle of the rear wing in the photos posted above : there is a small triangular flick up in the middle of the wing plane.

When teams without an F-duct choose to reduce the size of their wing planes, they move the whole assembly upwards so that it meets the top of the endplates. With the Renault f-duct blowing the main plane, I would assume that it is much harder to move the whole assembly upwards because of the shape of the ducting, so it looks like they reduced the overall height of the flap instead.

I would hazard a guess that the triangular flick up is to meet a rule defining the height at which you must run the rear wing. If Renault cannot run their reduced sized flap at the mandated height due to the shape of their F-duct, it would make sense that they have added the flick up so that the wing technically matches the height specified in the regulations.

That pic pretty much confirms it for me : the triangular flick up in the middle of the rear wing flap is there to ensure that the wing itself conforms with the mandatory wing height without compromising the F-duct positioning.

That is a nice workaround

sorry, my mistake. I was in the hurry and when saw "triangle shape" once looking at the photos emphasizing front wing just messed it up.

In fact it seems that they are carrying too much downforce... Their max speed is quite low if we look at the Different teams' Vmax. It's propably becouse they can't match F-Duct with smaller rear wing.

[tadzio89]

they run different downforce levels on Robert's car during FP2. someone noticed changes?

Yes, its quite low for me. Renault were always one of the fastest at the end of the straight this season.

[quidam]

Yes, without the F-duct

Also, just looking through some of the pics of the other teams, the Renault's seem to be running a bit more rear wing. Would this be because they may have lowered the rear wing's height a smidgen?

Renault will have another new front wing for Singapore GP Source: Renault Podcast.
