The day after “Lewis Hamilton Day,” Scuderia Ferrari is targeted on finalizing the final particulars in anticipation of the debut on February 19. Below the technical management of French engineer Loic Serra and the varied departments, the 677 undertaking ought to function a number of parts of continuity and others of serious change. The Ferrari 677 will probably be stuffed with improvements, with the newest rumors suggesting modifications useful 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 will verify that the chassis and aerodynamics undertaking has been accomplished for a while. The Maranello group is at present growing the automobile on dynamic check benches to extract the perfect primary setup for the 677. This activity is critical 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 whole dynamic check.
Positioned on the dynamic check bench, which simulates the numerous observe situations akin to banking, acceleration, braking, and corners, this has allowed the chassis division to raised perceive the brand new suspension format. The brand new kinematics pressured 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 special angle, the Ferrari engineers and technicians purpose to take care of braking drive and efficiency in gradual corners.
On the rear, the modifications will probably be minor however nonetheless current. Resulting from 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 stunned in 2024 for its wide selection of changes, nonetheless confirmed some limitations in sure areas. With focused interventions on dampers, bars, and the third factor, the brand new Ferrari single-seater for the 2025 Formulation 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 modifications, 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 parts of continuity will stay, extra than simply 10%. When a element is known as “new,” even a single bolt could make it qualify as such.
The 677, prepared for some weeks now, is anticipated to have a nostril just like the one debuted on the Haas VF-24 at in america Grand Prix weekend on the Cirucit of the Americas in Austin, connected to the mainplane. There can even be modifications to the flaps and their geometries, marking a transparent evolution from what was seen in 2024. Among the many parts 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 way 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 will not be anticipated to bear many modifications, with focused changes aimed toward optimizing cooling and aerodynamics. With more room between the suspension arms, the airflow in the direction of the undercut is extra open on the 677. That is consistent with a administration of the airflow directed to the ground based mostly on the experimental flooring seen in Las Vegas.
Adjustments are additionally anticipated to happen within the aerodynamics of the engine cowl, the place engineers have labored to optimize the warmth trade of the ability unit. This space confirmed its shortcomings throughout the 2024 Formulation 1 marketing campaign, with Enrico Gualtieri, the Technical Director of Energy Unit, pushing arduous 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 particular 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 increased, behind the air scoop. This may enable for a centralization of the plenty, helpful in dynamic phrases.
