Ferrari SF1000

Most recent diffuser. Also the gearbox tunnel is back, haven't noticed it on this year's car yet. Looks like they're trying some old proven solutions, same with the vertical floor fins.

In this video, The Race explains haas' infamous rear suspension problem and what could be causing it. Now, that aside, what's the important bit here is that haas buys its suspension components from Ferrari

I'm positive Ferrari faces the same problem. It all adds up, 1. With the general complaints all thru the season, of the balance being all over the place, especially in the rear. 2. Ferrari later clarifying with a statement that they "discovered a tuning fault in the rear hydraulic suspension", which they "corrected" (this was around the Russian/eifel gp i think). 3. Focus on rebuilding the rear suspension for 2021. This is one big --- up from the team. I don't believe in the 'revolving doors' policy, but that one guy who designed this must be fired.
Hats off to Leclerc tho. If this is true, his performance is legendary.

Ferrari also had this problem at the start of the season, no wonder, because the rear of the two cars are close. Ferrari got rid of the problem relatively quickly, Haas has difficulty with the heat from the cooler.

Can you elaborate on the gearbox tunnel part please? I've never heard about it

Sure. I'm talking about the feature circled here:


The gearbox and crash structure essentially float above the floor creating space under it right above the centre of the diffuser.
Air enters this area in the yellow marked sections here:


The shroud between the crash structure and diffuser seen here on the SF71H protects the airflow and gives it a contour to follow.


You want as much energized and predictable airflow over the top of the diffuser as possible, increasing the pressure difference to its underside. Ferrari has been implementing these shrouds since 2017, however I've yet to see someone copy it (the shrouds not the area underneath which is similar on all cars). It's not a big performance differentiator I guess.
Here is it from another angle on the SF90.

Is the central-upper part of the diffuser under the crash structure also different?

Potentially that little fin coming from the crash structure if you compare it to the Portuguese GP one here

Thanks @Fiunnnnf1 and @MtthsMlw!!! Amazing answers!! I didn't even know this stuff existed!

It is probably just the angle of the shot (or I'm going blind!)... but the inbound Vertical Strakes of the diffuser look to be... asymmetrical? They seem to have a slightly different curve along the bottom edge...

The outer strakes with the feather-like fins at the bottom seem identical, taking into consideration the angle of the shot... but even the far outer edges look asymmetric, regarding the fins on the otter edges of the diffuser.

Again, probably just the angle the shot was taken... but what I noticed, for what it is worth!

Guys notice how Ferrari's J vanes converge at the bottom in such a way that the bottom part almost looks like a cape. Does that mean that Ferrari enjoys the benefits of both J Vanes and the cape??

They do seem to have a hybrid solution, they have a smaller cape and it seems like the mini cape is sending air out and inboard the j-vanes.

Do you think those little vortex generators on the outside of the J-vanes, are to encourage more airflow inboard of the j-vanes?

A specific answer to your question is out of my pay grade I'm afraid, but I have a general theory.
So from what I've read, Ferrari faces very powerful y250 vortices due to their inboard loaded front wing philosophy. So those little vortex generators could simply be to assist the J vanes in generating counter-vortices. OR, it could be to generate extra vortices/energise existing vortices which then further enhance airflow to the bargeboard and floor area, increasing downforce. (Since the J Vane and Boomerang Bargeboard upgrade came together)
Also, about the 'minicape' thing, I think they did it so that it can interact with the y250 vortices sooner. (Capes have this advantage that they can be mounted further on the nose which means they interact with the y250 vortices sooner)

At #ImolaGP scrutineering, the #F1 Ferrari was fitted with ‘new’ floor. Very similar to initial one (raced in Austria before replaced in Styria), but tiny changes: winglet between diffuser & crash struct. (yellow), and metal piece stiffening flaps around diffuser (red)

What escaped us in Portimao was the return of the carbon “tunnels” which cover part of the area between the flat bottom and the gearbox (see the image below).These gutters have been on the Maranello cars since 2018, but they had disappeared on the SF1000.

No images of the damage to one of the cars that ended up in Bottas' bargeboard?
