Scuderia Ferrari SF71H

[tranquility2k4]

There are talks that the Ferrari's floor is working so well that it allows the car to run less wing than the Mercedes. Of course, the Ferrari PU is now on the same level as Mercedes, if not better.

All you need to look at is this excellent comparison (pay attention to front wing as well):

Comparison Setup Mercedes Ferrari Monza

And even with this much wing level, Hamilton was faster in speed trap than Ferrari and top speed in Monza is all about more power. If Spa wasn't enough, Monza confirms that SF71-H has better downforce to drag ratio than W09, something that was discussed here since cars were presented in February. In Lesmos, Ferrari wasn't lagging behind Mercedes in corner speed and these still aren't speeds were drag is starting to hinder acceleration trough corner, so more downforce for slightly more drag is acceptable there.

Ferrari PU seems to be better on acceleration, since they look like using electric power for longer in early acceleration from corner. However, there are strong arguments pointing towards Mercedes peak power supremacy, which is constant since 2014. And this fact is an astonishing achievement for Mercedes' amazing PU department.

I'm not great with the tech stuff but to me whilst Merc's spoon wing is larger in the central section, their wing looks thinner than Ferrari's at the edges, so if Merc ran a traditional wing with the same amount of downforce/drag as their spoon wing, I doubt it would look significantly different from Ferrari's wing? After all, the spoon wing is meant to be more efficient in terms of a downforce vs drag ratio isn't it?

Definitely, he still managed it very well with this kind of damage.

So, next one is Singapore and that’s the next possibility for Ferrari to bring the new wastegate pipe layout. Do you guys think they’re gonna go for it?
It was just tested once. Maybe they weren’t happy enough.

Maybe that layout was planned for next year?

I don't think so. RW dimensions and overall aero will change next year. If we don't see it in Singapore I don't know when we will.

Notice the Ferrari is still running a gurney flap though whilst Mercedes is not. That actually makes quite a difference.

Not saying that you are wrong, but maybe the change of RW dimensions is the exact reason they might be interested in trying different exhaust arrangement?

Next year's rear wing will also be higher. So the chance of getting a blown rear wing is very unlikely.

Hope to see it this year tho!

Btw, it's kinda strange Ferrari brought this new concept of sidepods since last year but doesn't seem to do many upgrades around it thru the year. The deflectors on the side, deflectors on the sidepod which extend it, always seem to stay the same thru the year. Any idea why?

Well when you look at how teams generally develop this area, you notice they don't usually change it too oftrn, since it's very important for overall flow structures. You may see one or two teams doing one (small) change of side pod intake design per year, mostly because its either a massive gain or the, made a massive screw up in thr beggining. Mercedes did it in Austria this year for a massive gain for the rest of the year.

On Ferrari, this area seems particularly well developed with clear design goals very visible. Being such, improving it might hurt some of those original goals and/or hurt further development potential for some other areas.

What I'm very intersted in, is why barge board updates are so scarce. There are two possibilities - either they are very close to development potential (hardly) or they are reluctant to introduce new parts that would improve downforce potential but at the great cost of drag. In my view, Red Bull has too many surfaces in this area causing substantial amount of drag for downforce they gain. Red Bull had 3-4 updates in this area since roll-out, while Mercedes and Ferrari each had only one.

Also, it's good to remember that teams learned about 2019 changes very early this season, so they probably started splitting resources between 2018 and 2019 cars at that time. This would hinder any development that doesn't benefit 2018 as much as other areas do (since 2019 cars will be so different, there aren't many parts you can translate to them) and you still have to work on low-drag configuration for Spa and Monza.

Can you elaborate on this point? What specific part of the bargeboard causes significant drag and how is the Redbull solution different than the other two?

The mid wing part. Everything above is to guide air over the floor, the midwing is to create a series of vortecies, some travel along the side of the floor, and some travel directly under the floor. Wings create drag, downforce comes with drag, Red Bull tried to maximize the surface area of this region and thus downforce potential. The Ferrari solution is inferior to the Red Bull in terms of pure downforce, however Ferrari might have been going for a more balanced solution in terms of downforce to drag.

... downforce comes with drag...

Technically is the other way around...

It’s not really like one causes the other. There is a resultant force acting on the wing, which can only act normal to the surface. Which can then be split into the horizontal and vertical components.

Drag doesn't inherently cause downforce, but downforce does inherently cause drag, which I think is what he was saying.

Yeah but the drag isn’t a result of the downforce, both are the result of the force due to the pressure differential between the two sides of the wing. Which can then be split into drag and downforce, pressure drag that is. Skin friction drag would occur in a flow over any body, so essentially drag is a result of the flow of any real fluid over a body. But what I was trying to say was drag and downforce/lift aren’t “real” forces, they’re just names given to the horizontal and vertical components of the force acting on an aerodynamic device.
