Ferrari SF21

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.

Did anyone post this picture (yeah tweet, but with interpretation of picture) yet?

The end is defined by rules, so they must to comply...
Like with everything, but I just wonder what advantage you gain with this design.
They can have thinner pipe = less weight, then the rules define it must be wider for the last few cm, so they changed the diameter back...
I think that internal packaging might be a more probable reason, thinner pipe, less bulk

Looks like they touched everything.

This is great, as it would be amazing to see 10 different winners this season!

The wastegate pipe causes its own bulge in the engine cover. Maybe it was done like this to minimize that needed bulge?

Definitely not the best angles to compare, but good enough for quick visualisation. Ferrari doesn't look too shabby in those areas in comparison to Mercedes...

The sidepods work looks interesting, there are a nice amount of changes here and there, which explains why Binotto was so bussy in the last part of the season. Not a great changes in the nose but with the limited amount of tokens to use I can understand that they considered that other areas would benefit them a lot more. We will see if they have done the right thing.

Only with the power improvement in the PU the car should a lot more competitive than in 2020 but Ferrari is unpredictable, usually in the bad sense of the term.

Yes, it could be another reason. They have (apparently) changed the turbo, for some reason they didn't (or couldn't) remove the wastegape pipe altogether, so perhaps they use a smaller section pipe to pack it more tightly... every milimeter counts...

The wastegate pipe exit isn't the only thing prescribed, they also are required to have a wastegate, which indeed means they cannot get rid of the piping either :)

It's weird to see Ferrari, the inventor of this type of sidepod intakes in 2017, 'abandoning' their typical design to copy that of other teams....
The sidepod bodywork is completely different too and it adopts the redbulian downwashy style.
Complete break with what they've been doing since... phew
Abandoning their design what do you mean? Since 2017 they've just evolved the lower SIPS design further and further. 2019 to 2020 there was the change where they got rid of the intake on the top side of the sidepod but what you see today is just ultra tight engine cover/sidepods with that Red Bull style crease, it's a natural evolution IMO, most of the grid following that Mercedes sloping sidepod thing they did with the W10
There is " " around "abondeoning".
I'm talking about he intake shapes.

But they retained a Ferrari style.
Now they have the RB style

it's all the things together... less weight = smaller part = less bulky = more space for other stuff = less heat...

btw SF1000 already have this, but this time it looks like they go another step in this direction...

Interesting, but, hasn't Mercedes gone "sans pipe" on their W12 for example? I'm a little confused... #-o

How can they not use any tokens for the nose??? It's been modified quite heavily similar to alfa Romeo.
It looks like that structural part (which is under "token regulation") is not touched only the aero environment of it.
