So far:

Merc / Mclaren / Williams using a tight, centerline cooling concept. Aston Martin in a totally different direction, but if the rumor of Dan Fallows (I give 5% credibility to rumors) isn't happy, that provide some clues.

Ferrari / Haas / Alfa Romeo, not nearly as tight as packaging. Big side pods with varying degrees of undercut. Maybe Ferrari trusts how much their PU is making now and can go with what I am imaging is a much draggier concept. Or maybe they are struggling some with cooling.

AT and RBR, based on the spy photos, look to be using a concept like Merc / Mclaren / Williams. That would suggest like Merc, Honda has been able to shrink the packaging and work on cooling efficiency.

Renault is the real wild card.

Mercedes dropped some video footage which shows the wake in motion.

It shows some things, but the weight of water makes it hard to see anything useful.

Is it just me, or is the vapour diffusing relatively quickly to what we've seen before?

Difficult to tell how comparatively wet it is - the high wind will also probably disperse the water in the air faster

Do you have an idea how much more powerful is the ground effect compared to last years cars in cfd ?

Not to mention that it was smartphone footage that was then butchered even more by twitter!

Here is are some vortices you can see clearer..
The rear wing has a more stronger vortex generation because of its size and pressure difference across its sharp edges.
At the core of the vortex also is a higher sheer rate so it can move those finer water droplets now...

Go to 1:55 in the video.

Dont think you're really seeing vortices there, well i certainly cant anyway, just a general wake

Probably it has been discussed before, apologies for that, but do we know what happens to rear wings during the season? Do they stay the same specs irrespective of downforce level requirements of different tracks?
