How? The black "thing" seems more like a film/plastic material.

The link says it is a special polymer developed for boating. The artical says it retains heat.... Metals tent to reflect radiation....
The following link http://www.radiantbarrier.com/physics-of-foil.htm states ...

Although two objects may be identical, if the surface of one were covered with a material of 90% emissivity, and the surface of the other with a material of 5% emissivity, the result would be a drastic difference in the rate of radiation flow from these two objects. This is demonstrated by comparison of four identical, equally heated iron radiators covered with different materials. Paint one with aluminum paint and another with ordinary enamel. Cover the third with asbestos and the fourth with aluminum foil. Although all have the same temperature, the one covered with aluminum foil would radiate the least (lowest [5%] emissivity). The radiators covered with ordinary paint or asbestos would radiate most because they have the highest emissivity (even higher than the original iron). Painting over the aluminum paint or foil with ordinary paint changes the surface to 90% emissivity.


So it might just be heat resistant black paint (I doubt it) cause a rim resembles aluminum foil.

He said somewhere else - maybe SKy - that they couldn't have their models as big as they would like either - I guess 50% rather than 60%.[/quote]


no doubt that the updated Marenello tunnel is better than the old marenello ..my point was there wasn't a big edge (negligible) over the Toyota tunnel which they've used for this year's car.

The better work very hard in qualy pace for next year, or they will suffer a lot with Kimi and Alo.

Which proves the supporters of the "F138 sucks due to the HUGE sidepods" theory, maybe, are correct!

Why do you think so?

re-Pj
In my view, shorter and sloping down sidepods are quite important here. There is no silver bullet, but careful management of the amount of air passing below rear wing as well as it's Reynolds number in the cross-section is key. In case of Red Bull I sense, their sidepod design minimizes the amount of this air flow.

The red bull sidepods aren't just lower. They are much smaller. That is superior packaging right there.

IMO it is impossible to draw any conclusions without knowing the details.
Firstly it can be that Ferrari engine needs more cooling than Renault. Secondly, RedBull uses a different type of cooling arrangement, they have one big exit at the centerline, and it can be that Ferrari actually uses rear wing better. Of course, what RedBull probably loses in that area they more than make up by using ramp-exhaust and throttle maps.

The undercut of the Ferrari's sidepods is so much larger at the rear.

that's what makes it look so nice, imo

Also worth noting that Ferrari have the vertical radiators which naturally require a higher sidepod.

re:timbo
I would think that concentrating radiator cooling exit below the rear wing (RB) creates a pressure depression effect (which is desirable from downforce perspective). By the looks of it RB is maximizing the potential of rear wing downforce. By detail design, they create such conditions that incident cool air as well as pass thru hot air are carefully controlled as to their flow around distinct elements at the rear of the vehicle.
As far as heat rejection is concerned between Renault and Ferrari engines, you can treat them as comparable in my view. Engine design isn't that varying between marques to leave much waste on the table between them. Efficiency of car design however is a much different story.
