I guess you change the AoA of the floor due to the loss of downforce at the rear lifting the rear structure up while the front end keeps producing more and more downforce pushing the edge of the floor into the ground.

So i guess whether it´s DRS or no DRS the front of the floor will eventually start hitting the ground given you run it low enough.

Seems like you were 100% right there sector. DRS sheds so much DF it makes the front of the car literally dive into the ground as the speed increases.

Is it me, or the view angle, or do the sidepod radiators seem to be placed vertical/ not as angled as last year's rads?

Imo, the shape of the sidepods of this RB11 (side view) do suggest that RBR kep a similar layout as 2014 anyway. But that pic gives me some doubts.



And seeing that STR put some heat sensitive colors and stickers exactly were the 2014 RBR had its exahausts, makes me think RBR too kept the same exhaust layout.

*Will Tyson, thewptformula, has. He's a member around here, a young and very good tech journalist. Just to accentuate that since he deserves the credit.

If I remember rightly he's done some excellent lap time analysis in the past and has put other so called professional experts to shame.

Thanks for the kind words. Was cruising this thread for RB11 pictures for my in depth analysis for my blog this weekend.

In response to the radiator mounting, they have been placed at a higher angle so the sidepods can cut in sooner but they can't place them vertically. Unless they are running something completely different to the conventional.

The Renault engine is still producing the same amount of heat as last year so the chances of producing much small radiators are pretty slim.

If this is true, then the RB11 packaging is really crazy, considerung the extremely tiny air inlets and alot smaller sidepods.

I bet Renault and Red Bull worked closely on packaging the PU this time around.

Scarbs said the same. Renault 2015 PU does have the same cooling requirements as last year's. Which is a lot more than ferrari and merc do.

Interesting.

Acoording to AMuS, Renault is basically working on two different PUs/engines; the first one is a '100%' Renault/RBR product while the second one is modified by Illmor. They tested the latter (a mono-cylinder) last week for the first time in Viry.

If there is even some truth in that article it once again shows the glaring relative weakness of the Renault PU last year.

Wahrscheinlich wird der Ilmor-Input mit Rücksicht auf die Standfestigkeit erst beim GP Spanien Premiere feiern. Eines haben beide Versionen gemeinsam: Turbine und Verdichter sind nicht getrennt. Für eine Kopie der Mercedes-Idee fehlte die Zeit.

Anyway in any case no split turbo like on the Mercedes unit, according to the sources.

I'm not sure I agree with that considering what Toro Rosso has achieved with packaging compared to all the Mercedes powered teams including the works team themselves.

But then maybe we have to consider the size of there air intake compared to the rest?

The STR is a particular case because two of its biggest/engine radiators are not located in the sidepods.

Scarb's/Newey's informations match Abiteboul's infos; if the 2014 engine had knocking problems, then it charge air and/or oil/water cooling must be quite high.
And if the 2015 engine has the same cooling requirements but produces (much) more powerful, that means they (partly) have eliminated knocking : P
