McLaren MCL33

[Vanja #66]

The air is going where it's going, T-wing is too small to have any influence. In such a small angle of attack compared to ground, it looks to be useless, but it's actually in a relatively high AoA because of rear wing downwash in front of it. And because it has minimal head-on cross-section, it creates minimal drag. It's a very efficient piece of aero surface, not much more to it.

While this video is useful, the effects will be slightly different with the T wing being placed below the rear wing instead of above it. It actually looks like it is placed very close to the stagnation point of the rear wing.

Would be interesting to see some CFD run on it.

Well, but if the intention is to have vortices merging, I'd guess the effect is more or less the same no matter the placement. Even last year the height of the T-wing would vary from car to car, with Williams going as far as having two.

I think, looking at the beginning and end of the t-wing and its angle to the neutral plane, that they're trying to get air under the rear wing in the central area and above in the outer zone. I wonder if they are trying to reduce the drag (I know just the absolute minimum about aero)

If you add more air to the downside of rear wing it'l create more downforce not reduce drag

The proper term is helicity.

There are more differences, the endplates have a change in the back, and the rips next to these on the inside are smaller.

[DiogoBrand]

It looks like all those changes are aimed at increasing the intensity, or even the efficiency of the outwash.

Alonso used new rear wing in the race, Vandoorne not.
Have we seen this wing here?

I wonder the same, no pictures yet?

Didn't hear anything about a new rear wing; only new T-wing and front wing. Can you share the source please?

[Marco Alves]

Looks like they added a small central "snow plough"

Does anyone have better photos of this? I still have not realized what that is.

Look at detail of bottom insert. Did not look like one piece in previous pictures ??

New front wing tested in Monaco looks ready to be raced; also has sponser FxPro's logo
