The day after “Lewis Hamilton Day,” Scuderia Ferrari is targeted on finalizing the final particulars in anticipation of the debut on February 19. Underneath the technical management of French engineer Loic Serra and the assorted departments, the 677 undertaking ought to characteristic a number of components of continuity and others of serious change. The Ferrari 677 will probably be filled with improvements, with the most recent rumors suggesting adjustments helpful for Charles Leclerc and Lewis Hamilton.
Chassis and Suspension
Though the title of the brand new automobile coming from Maranello is just not but outlined, we are able to affirm that the chassis and aerodynamics undertaking has been accomplished for a while. The Maranello staff is presently growing the automobile on dynamic take a look at benches to extract one of the best fundamental setup for the 677. This job is important because of the change to the entrance pull-rod format, which has required extra studying time than anticipated, with the previous Mercedes driver overseeing the complete dynamic take a look at.
Positioned on the dynamic take a look at bench, which simulates the numerous observe situations comparable to banking, acceleration, braking, and corners, this has allowed the chassis division to raised perceive the brand new suspension format. The brand new kinematics compelled a remodelling of the higher and decrease wishbones, aiming to not lose the strengths of the previous push-rod system. With extra anti-dive (a extra inclined higher wishbone) and a unique angle, the Ferrari engineers and technicians goal to take care of braking drive and efficiency in sluggish corners.
On the rear, the adjustments will probably be minor however nonetheless current. On account of a slight variation within the wheelbase for a extra balanced weight distribution, the rear finish has been “tweaked” to accommodate the developed pull-rod. The suspension system, which shocked in 2024 for its wide selection of changes, nonetheless confirmed some limitations in sure areas. With focused interventions on dampers, bars, and the third component, the brand new Ferrari single-seater for the 2025 System 1 championship is anticipated to have a wider working window, even with elevated aerodynamic load.
Aerodynamics and Ferrari 677 Energy Unit: the Improvements
Visually, the brand new Ferrari SF-25 is anticipated to bear vital adjustments, with notable modifications to the entrance wing, nostril, and bodywork. Frederic Vasseur‘s statements citing “90% new” ought to be taken with warning, as some components of continuity will stay, extra than simply 10%. When a part is named “new,” even a single bolt could make it qualify as such.
The 677, prepared for some weeks now, is anticipated to have a nostril much like the one debuted on the Haas VF-24 at in the USA Grand Prix weekend on the Cirucit of the Americas in Austin, hooked up to the mainplane. There can even be adjustments to the flaps and their geometries, marking a transparent evolution from what was seen in 2024. Among the many components of continuity, the “curled” construction seen in Singapore between the endplate and the wing mainplane ought to stay, together with a greater deformable construction for the flaps.
By means of improved and cleaner administration of airflow directed in the direction of the middle of the automobile because of the pull-rod suspension, Ferrari has closely labored on the bodywork. The sidepod inlets are usually not anticipated to bear many adjustments, with focused changes geared toward optimizing cooling and aerodynamics. With extra space between the suspension arms, the airflow in the direction of the undercut is extra open on the 677. That is in keeping with a administration of the airflow directed to the ground primarily based on the experimental flooring seen in Las Vegas.
Modifications are additionally anticipated to happen within the aerodynamics of the engine cowl, the place engineers have labored to optimize the warmth alternate of the facility unit. This space confirmed its shortcomings through the 2024 System 1 marketing campaign, with Enrico Gualtieri, the Technical Director of Energy Unit, pushing laborious to enhance each efficiency and reliability. Engine maps have additionally been optimized for a noticeable acquire in qualifying lap instances. The Italian media requested for a selected time acquire in tenths, however to keep away from creating expectations, the supply stated they’re very optimistic, with a big benefit over the SF-24.
The radiators are anticipated to take care of the identical format, however some could also be positioned larger, behind the air scoop. This may permit for a centralization of the plenty, helpful in dynamic phrases.
