Could you share?

Might have to go back on myself

From this picture the 'slot' has a different shape to the previous image. It could still be a slot that could look different based on the angle, but I would find it more likely to be a shadow due to that

Pretty clear to see there's no slot on the left hand side of the diffuser. This is an absolute red herring

The two sections are offset and because of the view angle to the left side of the diffuser they overlap. But if you zoom in on the brightened image you can see a transition.

I don't think it's a slot. It's an extra vane on the outside of the wall of the diffuser.

[myurr]

Actually I take that back, perhaps it is a slot...

Guys its just reflection of tire on shiny clear coated surface.

[BlueCheetah66]

If we are being completely honest, we can't really say with any certainty what it is. I think its just a reflection, however there is not a clear picture with enough angles to say for sure either way.

If it was there, it would need to be done in a way that there would still only be one section if intersected in the Y-Plane, which should be possible.

It would also have to be 'tangent continuous' which if I'm being honest, I don't know the meaning of. If someone could explain it I would greatly appreciate it.

I think faintly you can also see the bend that produces the shadow on the other side.

There is a vertical slit in the diffuser of RB19 . I think it's to increase the efficiency of the diffuser.

This shot has different lighting but it appears exactly the same.

[myurr]

I'm pretty sure it's an overlapping slot, so viewed directly from the side you wouldn't see the hole.

Diffuser getting lots of flow from the upper bodywork through the mouse hole it seems

It's getting flow from the undercut as well via underneath the front sidepod openings.
To me, it appears as if the diffuser is being blown by the front undercut flow where some of it accelerates to the side undercut.
Why I say this is that side undercut leads straight into the mouse hole. They have made sure that surface from undercut to mouse hole is basically a vertical slab, no undercutting and that slab is higher than the mouse hole. So that flow is basically rammed through the mouse hole; in effect blowing the diffuser.
I promise you this is not aero mumbo jumbo. Just trying my best to describe what I think is happening without pictures.

I thought it was a shadow at first but I've now seen several photos with it present from different angles so it likely is there

Could be a gurney flap as well.

The position doesn't make sense for it to be a gurney.

That's based on what you understand the classical gurney to be. But you do not know what they are trying to do.
It doesn't look like a hole to me.
It can simply be a gurney used as a turbulator.

Interesting! I googled this "turbulator" and you might be on to something.
