Ferrari SF-25

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

extra strake on the outboard side of the endplate is cheeky

As usual, @Auto_Racer_it is first at the scene and we can take a look at new geometry details thanks to them 😎

Changes are subtle, but bigger than what they appear at first sight. Not as big as what Mercedes did, but then again Ferrari had the least flexing anyway

I think the biggest change in terms of performance is the endplate junction and outwash treatment, which may also be a mechanism to recover some of the balance loss with less flexing. At low speed, steering angles and thus front wheel angles are higher and this front wing performance is different to lower steering angles at high speed

Flaps have higher chord now on Ferrari it would appear, while the 2nd element (which carries all the vertical load to the nose basically) is different and this could also be for structural reasons

Front view of flap trailing edge is probably very similar, and it would appear the wing still carries more inboard loading

Agree with this. There's two direction to this, one for vertical load (largely originating from the increased test in vertical some time ago) to stop droop in a "moustache" direction. Secondly, and likely more to compensate for this regulation shift imposed now, torsional flex which is used to "hold" the two upper flaps in deviation from tested criteria.

Looking, for example at left hand side of wing, the top two flap would be flexing that second flap in a clockwise direction as they are effectively "cantilevered " from that second structure. And so imparting rotational torque (torsion) directly into tbat second "beam" to anchor them. Increase of torsional performance resistant to more load in pushing down of trailing edge of those two top flap.

That's very minute, compared to even years ago with red bull and Mercedes. Not much movement at all, especially with that inner adjustable area. Also the "V Power" on the bigger elements shifted, showing those are twisting with the aero load, which is expected, so the upper flaps relative the red mark, may have even less movement relative the the main elements than perceived.
For Sure!!

I am wondering why people are looking at the inside part of the wing? The flexing, since it is mainly coming from torsion, are the most important at the outer end of the wing. This part has the least influence overall.
