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.

A longer wheelbase, according to THE RACE :

Possible pull-road internals:

Lower upper back wishbone front suspension for both increase the anti-dive and to clean up the area in front of the sidepod air intake:

Inclined front suspension triangles will increase the tyre foodprint by almost 2cm due to the wider front axel, which is beneficial for better cornering and tyre race management

Supposedly they went to the RB20 horizontal radiator route with the new sidepod layout and air intake:

My understanding is that every team has been running the max wheelbase since 2023, with only Sauber ever running a shorter wheelbase in 2022.

This is more likely down to the angle from which the photo was taken.

Autoracer who are the top tier source for Ferrari are also stating that the wheelbase has increased

Are they doing so through independent verification or because they saw the same comparison? All these photos and tweets and whatnot all go through the same circles online.

Autoracer don't just publish what others write. In fact, they've recently been in conflict over the Race themselves over the flexi wing affair.
The design of the upper triangle features a more rearward position in the attachment to the chassis ( completely redesigned for the SF-25) and an apparent lower anti-div e. The attachment point to the wheel corner has been raised and the brake ventilation duct passes through it. All choices also due to a slight forward shift of the front axle with an extension of the wheelbase . All changes aimed at creating a cleaner passage of air towards the bottom.
The attachment of the front suspension and the wishbone to the chassis has changed because on the Ferrari SF-25 the technicians led by Diego Tondi pushed to lengthen the wheelbase of the single-seater , moving the front wheels away from the entrance of the sidepods.
Autoracer write it twice and are emphatic that the increase of wheelbase is the driving force behind front suspension changes. They wouldn't have these insights without this being their own work

I'm happy to be proven wrong.

WB is only slightly longer, but longer. Their analysis combines their own efforts and some extra info. We know they are well informed all the time, unlike Nugnes, f-uno-at, etc

Fair enough, thanks for the info! I feel like maybe it might have been quite useful to include that info from the start, no? lol

Given how the internet is these days, just blurting out claims like this isn't at all enough for me. And shouldn't be for anybody.

How important are aerodynamic junction losses in an F1 car in general, especially for the SF25, and how much are these losses mitigated by attaching fairings at the junction between the chassis and the suspension arm?

Is anyone able to really briefly summarise what the benefits of the pull vs push front is? As is what the actual aero benefits are
It seems to be the real estate from the brake cooling inlet is the driver. As on the push o setup, a junction from the pushrod into the inlet (junction creates loss) and provides less flow control.
The benefit seems to be utilizing the sculpture of the exit condition for the inlet, providing more mid-wake outwash for the front tyre.

Ferrari F1 SF-25 vs McLaren F1 2025 – A Technical Breakdown with Engineer Riccardo Romanelli

In today’s episode of Race Tech, our guest, engineer Riccardo Romanelli, will analyze the front suspension choices made by Ferrari and McLaren ahead of the upcoming 2025 Formula 1 season.

While 2025 marks the final year of the current technical regulations, teams are still pushing to refine their designs. Ferrari aims to challenge the reigning world champions with the SF-25, introducing a brand-new front suspension as its most significant innovation.

Compared to the SF-24, which will debut on February 26 during pre-season testing in Bahrain, the SF-25 features a Pull Rod front suspension, moving away from the Push Rod concept used in previous years.

errari SF-25: Key Design Changes for 2025
Our guest will now highlight the most significant innovations in the Ferrari SF-25 and how they differ from its predecessor.

1. Aerodynamic Refinements
At the end of 2024, Ferrari introduced a new floor, which serves as the foundation for the SF-25. One of the most intriguing changes involves the redesigned airflow management under the sidepods:

Slimmer sidepod undercuts improve airflow towards the rear.
Smoother lower sidepod surfaces enhance airflow efficiency, directing it more effectively toward the floor and rear wheels.
A more extreme floor design increases downforce while minimizing the risk of porpoising.
2. Redesigned Upper Sidepods and Rear Fin
The upper sidepod profiles have been slightly raised, channeling cleaner air toward the rear of the car, reducing turbulence and energy loss.
The shark fin has been downsized compared to the 2024 version, likely for weight reduction and improved stability.
