Scuderia Ferrari SF90

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!
Just to suggest this interesting article about the POU usage by Mercedes (it's in Italian but Google translation sounds pretty well!).
To be noted that Ferrari 2017 had the same concept banned by FIA and, as far as I know, the more the offset between push rod and vertical rotation axe, the more the height variation directly proportional to the steering angle.
It's a matter of pure geometry...

There will be a B car in Hungary with suspension updates cause this version proved inadequate to put in temperature the newer spec of Pirelli tyres and aero updates as well

I hadn't really appreciated how tight that inner corner of the top front wing flap is there - is that new, and is that likely meant to give some effect, or is it just a consequence of how they want the outer curvature to be while keeping the inside as straight as possible?

they want to maximize the front wing area while keeping the y250 as low and as weak as possible

Funny how Alfa and STR look so strong considering their FW design :?

The rules place a geometric limit in this area and Ferrari are running their flaps to the full extent they are allowed. It's not about making the Y250 weak. You're the only person in the world who thinks they want a weak Y250...
Turbo says "Dumpster sounds so much more classy. It's the diamond of the cesspools." oh, and "The Dutch fans are drunk. Maybe"

You want a Y250 vortex of sufficient strength such that it is able to deal with the front wheel wake and provide downwash to the bargeboards and floor but one that is not unnecessarily strong otherwise the induced drag penalty becomes too great.

Oh, right, hadn't realised that meant me rekindling that discussion again! Just_a_fan, so you are saying that rather sharp corner on the underside of the top flap is just to get the sharp slope on the outside, while keeping the inner, downforce producing part as straight as possible?

exactly
the problem is there is enough strenght as it is with the actual fwingsand also y250 is not the best way to deal with front wake, there are also deviators for that so you end with too much y250 anyway

How reliable is that source? I feel like pretty much every week reports massive Ferrari updates only to see tiny ones appear. They have to do a B-spec with suspension improvements and such if they know it will help otherwise they are a year behind on tyre knowledge... A good charge after the summer break can only do them good leading to next year.

i dont know . italian sport magazines are more reliable than usual news magazines but they are not autosport that it is usually the more reliable... but everybody talks about the B spec... it s the date and the amount of changes that it is the issue

That's because you're assuming that all problems that Ferrari is facing are coming solely from the front wing design, without having any proof that supports this hypothesis.
