Williams also has a 2019-spec wing:

And a closer shot of the FI wing on the car:

With regards to performance, lap times with the full 2019-spec cars should be equivalent to early 2018 according to Albert Fabrega.

Apparently having that tunnel subdivision doesn't count as more elements, at least Williams believes that to be the case.

FINDIA is ready for snowplowing in Montmelo Feb 2019.
Looks good, I like it a lot.

Honestly, to me this is more than 5 elements.

Maybe the 5-element rule will only be on the outboard end?

The Williams version is much more what I was expecting - the tip being angled to get some flow outboard and aggressively upwards.

I don't doubt it, introducing rules with obvious loopholes is an FIA specialty.

Seems like Red Bull only took off the cascade elements.

Looks like they are still trying to make out-wash front wings! #-o

Although they do appear to have severely limited options now.

I'm getting annoyed with this in-wash stuff. FIA/FOM never said they'd be looking to in-wash the front wing tip wake - just reduce the aggressive out-wash which increases the car's wake width to the detriment of other teams, then Scarbs and the motorsport network got it wrong and started all this nonsense. That said, a wide span wing does not necessarily mean the tip vortex passes around the outside of the wheels - read the work of Diasinos on front wing span and wheel vortex interactions.

The endplate seems much taller, teams aren't even using the full span at this point.

The picture with flow viz appears to show almost all of the front wing's flow going inside the front tyre. Very little red colour on the outer face of the tyre compated to the inner face, for example. Also look at how far inboard the purple colour is indicating mixing of outer wing flow with inner flow.
If you are more fortunate than others, build a larger table not a taller fence.

Yeah, the wings are deeper, that's why.

As jj says, they're not going to go for in-wash wing designs. Especially not with even wider wings. They're going to go for more up-wash to lift air over the wheel rather than around the outside, that's all.

If the FIA wanted in-wash wings they would have narrowed them another 20cm.
