📷 Our first in depth look at the SF-25 ahead of its shakedown test at Fiorano.

Pretty much everything has been revised. Lots of interesting details, all will be posted in this thread.

Hopefully compression is on our side this time, please ignore spelling errors.

❗️ Front and side view, we can see a ton of differences compared to the SF-24.

Our first major one start with the pull-rod front suspension. It seems the entire front assembly has moved upwards ever so slightly at the inboard chassis pick up points. Compared to a push-rod, the pull-rod lowers the center of gravity ever so slightly and can also potentially be lighter due to the fact that our rod is not experiencing any buckling forces as with the push-rod.

Our front wing has remained largely similar, if not the exact spec from Singapore '24. The nose is slightly more tapered, however nothing noteworthy. As I wrote in the image, I expect most of the work on the front wing to have gone into the material design.

Front view, we can see a very deep undercut and the newly shaped P-inlets. We also the lower mirror faring and the rolled tip for the mid-wing, all carefully working together to manage the vortex shed by the mid-wing.

Other changes include the front brake ducts, the new medium downforce rear wing and the redesigned 3rd floor fence. All discussed in the image.

❗️ From this 3/4 view, we can see a reworked G-line. More expansion near the mid-floor to power up our edge wing. More floor edge and better inflow quality.

❓ Cockpit postion comparison.

A few disclaimers first:

-The two photos are at slightly different angles, which already makes this comparison inaccurate.
-The lines themselves have a width (any smaller and compression would make them invisible) which again affects the accuracy of this comparison.
-It's better to have this confirmed by the team or an insider source. So for now take this as speculation.

I've aligned the images as best I possibly can, it seems that on the SF-25, the cockpit and airbox intake has moved slightly rearwards. Requires further analyses or confirmation.

📄 It also seems that our outboard pickup points at the front has lowered as well. Giving the suspension assembly more droop.

Again, we're at the mercy of the angles here, so take this as speculation rather than confirmation.

🔵 The most interesting detail to me is the lower wishbone fairing at the rear.

It looks one complete fairing with a slot gap for the rear lower wishbone member, resembling a dual element wing. That means our lower wishbone, track-rod & driveshaft are all encased in the same fairing. Not a very common trend at the moment.

This deserves a closer look with better lighting and angles to be certain.

🔨 From this rearview we can deduce that the lower wishbone fairing seems to be operating at a down washing angle near the outboard pickup.

From this angle increases my confidence in this being a single encasement fairing.

🚪 We've kept the slit exit & engine cover bodywork has been revised, however largely similar.

The curvature combs aren't accurate, just there to give an idea of the local curvature of the bodywork. 2nd slide is a brief explanation (SF-24_ of the purpose of such a design.

📎 Still very clearly pull-rod at the back. Once again, very hard to see what is happening with the lower wishbone fairing.

➡️ A closer look at the 2nd most inboard fence free-tip. As explained in the cover image, I imagine the idea here is to use the vorticity to drive more downwash into the upper surface of the floor.

🗂 Beam wing, very similar specification to last seasons' 'mid-downforce' option.

We can also see the cooling cannon outlets have a very similar outlet volume. The forward outlet looks slightly reduced in volume.

🔗 I've found a much better angle of the rear lower wishbone fairing, and it confirms it is a single fairing encasement, as I initially thought.

It seems the rear wishbone member almost forms a 3rd beam wing element, although this angle makes the relative distance and AoA to the lower beam wing element really hard to judge.

❗️ The sidepods have a very aggressive taper and change of angle around the mid-floor. The idea is clear, they are trying to create a region of high static pressure by aligning the initial portion of the side pod like this.

This will help further manage the upper portion of the front tyre wake. This change of direction around the cockpit is very aggressive, the only concern here is whether you can keep the flow attached around such a sharp curvature.

🔵 First change spotted on the new floor is the reshaped double mouse hole. This hole feed the diffuser wall vortex with clean air to keep the core compact. This effectively increases the available diffuser volume, however we are slightly more prone to bursting if we push this too hard. The small extension between the two hole is a vane/strake that help entrain air into the diffuser.

Disclaimer: Apart from the fact that the floors in these images are 12 months apart, and the SF-24 floor has undergone many changes since, the mouse hole geometry remained pretty much the same throughout 2024. This is why I am okay with using such an old image to compare to.

🔴 تحلیل تصاویر Ferrari SF-25 🔴 (نسخه فارسی)

تصاویر جدیدی از SF-25 منتشر شده که جزئیات مهمی را نشان می‌دهند.. موارد بسیارزیادی بازطراحی شده اند و تغییرات جالب زیادی وجود دارد.خلاصه ‌ای از آپدیت‌های فراری به شرح زیر است :

🔍 نمای جلو و جانبی - تغییرات کلیدی

✅ Pull-Rod Front Suspension
• به نظر می‌رسد که کل Front Assembly در نقاط اتصال داخلی Chassis Pick-Up Points کمی به سمت بالا حرکت کرده است.
• در مقایسه با سیستم Push-Rod، سیستم Pull-Rod کمی مرکز ثقل خودرو را پایین‌تر می‌آورد.
• علاوه بر این، چون در Push-Rod ممکن است نیروی خمشی به وجود بیاید، Pull-Rod پتانسیل سبک‌تر شدن دارد.

✅ Front Wing & Nose
• بال جلو تقریباً مشابه نسخه Singapore 2024 باقی مانده است.
• به نظر می‌رسد بیشتر توسعه روی مواد سازنده بال جلو متمرکز شده باشد، نه تغییرات هندسی.

✅ P-Inlets & Deep Undercut
• یک Undercut بسیار عمیق و P-Shaped Inlets در طراحی جدید دیده می‌شود.
• طراحی جدید Lower Mirror Fairing و Rolled Tip برای Mid-Wing به مدیریت Vortexهای تولیدشده توسط Mid-Wing کمک می‌کند.

✅ سایر تغییرات مهم
• تغییر در طراحی Front Brake Ducts
• Medium Downforce Rear Wing جدید
• طراحی مجدد 3rd Floor Fence برای بهینه‌سازی جریان هوا
• توسعه در G-Line، افزایش حجم در Mid-Floor برای تقویت Edge Wing و بهبود کیفیت جریان هوا در لبه‌های کف خودرو

🛑 Cockpit & Airbox Positioning

📏 Cockpit & Airbox Intake کمی عقب‌تر؟
• مقایسه تصاویر SF-24 و SF-25 نشان می‌دهد که Cockpit و Airbox Intake کمی به عقب جابجا شده‌اند.
• اما به دلیل تفاوت زاویه دوربین، این مورد قطعی نیست و باید منتظر تأیید فراری یا منابع داخلی باشیم.

📏 Outboard Pickup Points در جلو پایین‌تر آمده‌اند؟
• به نظر می‌رسد که Outboard Pickup Points در Front Suspension پایین‌تر رفته‌اند که باعث افزایش Droop Travel می‌شود.
• اما باز هم، این فقط یک مشاهده تصویری است و نیاز به تأیید رسمی دارد.

🔍 Rear Suspension & Wishbone Fairing

🚀 Lower Wishbone Fairing - طراحی خاص و جدید
• Lower Wishbone Fairing شبیه یک Dual-Element Wing طراحی شده است.
• این طراحی باعث می‌شود که Lower Wishbone، Track Rod و Driveshaft همگی درون یک ساختار یکپارچه قرار بگیرند.
• این سبک طراحی در حال حاضر در F1 رایج نیست، بنابراین می‌تواند یک توسعه بسیار جالب باشد.

📏 Fairing Angle & Downwash
• این Fairing در نزدیکی Outboard Pickup زاویه Downwashing دارد، که احتمالاً به Airflow در اطراف Rear Suspension کمک می‌کند.
• نیاز به بررسی بیشتر با تصاویر دقیق‌تر است.

🛠️ Engine Cover & Sidepods

🔍 Engine Cover & Cooling
• Engine Cover همچنان Slit Exit را حفظ کرده اما بازطراحی جزئی داشته است.
• خروجی‌های خنک‌کننده تقریباً مشابه هستند، اما به نظر می‌رسد که خروجی Forward Cooling حجم کمتری دارد.

🔥 Aggressive Sidepod Tapering
• در ناحیه Mid-Floor تغییر زاویه شدیدی وجود دارد که باعث ایجاد یک High Static Pressure Zone برای کنترل بهتر Front Tire Wake می‌شود.
• این طراحی جسورانه است، اگر Airflow متصل بماند، بسیار مؤثر خواهد بود، اما ریسک جدایش جریان هوا (Separation) نیز وجود دارد.

🌀 Rear Aero - Beam Wing & Floor Details

✅ Beam Wing & Rear Wishbone Geometry
• Beam Wing مشابه نسخه Mid-Downforce Spec فصل قبل باقی مانده است.
• به نظر می‌رسد که Rear Wishbone Member تقریباً مانند سومین عنصر Beam Wing عمل می‌کند.
• اما به دلیل زاویه عکس، مشخص کردن زاویه حمله (Angle of Attack) این عضو نسبت به Lower Beam Wing دشوار است.

✅ New Floor - طراحی جدید Double Mouse Hole
• Double Mouse Hole جریان هوای تمیزتری را به Diffuser Wall Vortex هدایت می‌کند و باعث می‌شود که Vortex Core جمع‌تر بماند.
• این کار عملاً حجم Diffuser را افزایش می‌دهد، اما اگر فشار بیش از حدی به آن وارد شود، ممکن است باعث Vortex Bursting شود.
• یک Extension کوچک بین دو حفره، مانند یک Vane/Strake عمل می‌کند تا هوای بیشتری را به داخل Diffuser بکشاند.

📏 مقایسه با فلور SF-24
• هندسه Mouse Hole در طول فصل 2024 تقریباً بدون تغییر باقی ماند.
• بنابراین استفاده از تصاویر قدیمی SF-24 برای این تحلیل معتبر است.
