Scuderia Ferrari SF91?? Speculation Thread

A place to discuss the characteristics of the cars in Formula One, both current as well as historical. Laptimes, driver worshipping and team chatter does not belong here.

Hi all,

about Turrini: he writes about CFD and WindTunnel not for the bad 2019.. but because he always told that sending Resta to Alfa/Sauber was a mistake in the 2018.. and the last Ferrari made by Resta was the 2017 one (the best for downforce in the last 10 years for Ferrari..).

so his post is not pessimistic about the actual project: he hopes that Resta will be heard as it happened in 2017

bb and happy new year
Was Simone Resta chief designer of those years? i remember that was under Binotto as TP.

Wouldnt 2018 have had better df than 2017?

Binotto has been TD since 2016
The SF70h was designed by Simone Resta and Enrico Cardile (Aero)
The SF71h by Simone Resta
And the SF90 by Enrico Cardile
All according to Wikipedia...

The idea with that car was to make it more efficient by cutting drag, one area where Merc was ahead the year before. This came with a loss of peak df.

definitely not: the sf70h mastered hungary, spain, monaco, singapore.. while the sf71h was the first step in the low drag concept of the sf90.
the Sf70h was the best in class, but the pu upgrades failed in the second half of the season.

Some speculation.
The exhaust layout is quite likely I'd say.

It would be really funny if they went back to a traditional sidepod just as Mercedes copy their old design.

It would be even funnier if Mercedes did it and then went ahead and made a faster car to... :lol:

From reading it, it doesn't seem like they are talking about the inlet and more about the overall shape of the sidepod, a more aggressive downwards slope which the SF90 lacked.

With that said it would be funny if what you said came to pass :D

More speculation:
- longer cape
- raised front suspension (upper wishbone connected outside the wheelhub like on the Mercedes)
- third element now hydraulic

I'm afraid Ferrari will have a hard time understanding the set up at the beginning. Not sure why they waited for that long to finally go for a front suspension change like others (hydraulic third element included). Only one season left in which they can benefit from it. Very limited time to adapt to such a significant change. They need to get on top of things quite fast.

Tough situation indeed, in relatively stable rules, these would be fine, even if they struggled innitially they could catch up before mid season and have a good season and basis for the next one.

With the biggest rule changes perhaps ever in sight, if you struggle in the flyaways i think that's it... all resources will be moved to 2021.

Maybe they see that an SF90 EVO as it is won't be able to compete.
And maybe with simulation tools and all that they can hit it out of the park right away, who knows.

Some more speculation:

- There won't be a fully hydraulic third element, but, like in 2019, a hydraulically controlled traditional one
- Outwash front wing, but with more load on the outer parts
- Cooling inlet of the radiators will remain positioned on the top
- A slimmer Coca-Cola area
- A lot of work has been done on the rear floor area
- More rake, shorter wheelbase
- Architectural changes to the PU (as already known) and to the hybrid part to increase energy recovery
- Better consumption and reliability

Sounds quite likely, more than what motorsport Italy has reported.
It'll look very similar to the SF90.

If they use more rake and shorter wheelbase, it could mean they want more downforce at lower speeds but keep the low drag nature at higher speeds.

Sounds like downforce at the cost of efficiency to me.

Wouldn't you lose some aero platform stability by shortening the wheelbase? Also you'd have to rely more on the bargeboards to seal the floor which has the potential to choke the floor and diffuser with too long a wheelbase? Maybe a shorter wheelbase allows you to use a strong vortex from the bargeboards without choking the diffuser like a long wheelbase would?
