The ears are closed, so I guess they weren't bluffing when they said they wouldn't run the DRD until later in the season?

That's not the thightest packaging from what I saw. Lots of free space between cooling inlets and some devices....

Not only that, but hints at a strong secondary function (discussed earlier in thread) as why would you take the drag but not the gain?

Or did Disney sign up as title sponsor?

The ears are there because they are build into the chassis (rool-hop). They are not remoable like Sauber's

[korzeniow]

Might the ears not make for cleaner air going back to the rear wing? At high speed, when the airbox is "overfilled" and spilling air out to each side.

You don't need efficient rear wing at higher speeds on straights.

You don't need efficient rear wing at higher speeds on straights.

However, you could do with an efficient rear wing under braking... when the airbox* is hideously overspilling.


*this is pretty much the design goal of the airbox OML - minimise separation from spillage so flow onto the rear wing is as consistent as possible.

And they removed the black thing they placed inside the intake since Barcelona tests

This only reinforces my point, IMO.

So, by the look of the monkey seat it seems they will test DRD

[Pandabeer]

Sure they will, at least in FP1/FP2.

This looks like this



It's like the nose of the car is angled in such a way as to anticipate aero load.

It goes to show how far ahead these F1 engineers are in that they can design for such details.

"r" shaped vanes seen last year on the bottom of the vertical deflectors are back.
