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 venture ought to characteristic a number of parts of continuity and others of serious change. The Ferrari 677 will likely be filled with improvements, with the newest rumors suggesting adjustments helpful for Charles Leclerc and Lewis Hamilton.
Chassis and Suspension
Though the identify of the brand new automobile coming from Maranello is just not but outlined, we are able to affirm that the chassis and aerodynamics venture has been accomplished for a while. The Maranello staff is at the moment growing the automobile on dynamic check benches to extract the most effective fundamental setup for the 677. This process is important because of the swap to the entrance pull-rod structure, 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 monitor circumstances corresponding to banking, acceleration, braking, and corners, this has allowed the chassis division to higher perceive the brand new suspension structure. 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 unique angle, the Ferrari engineers and technicians purpose to take care of braking drive and efficiency in gradual corners.
On the rear, the adjustments will likely be minor however nonetheless current. Attributable to 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 ingredient, the brand new Ferrari single-seater for the 2025 Formulation 1 championship is predicted 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 predicted to bear vital adjustments, with notable modifications to the entrance wing, nostril, and bodywork. Frederic Vasseur‘s statements citing “90% new” must be taken with warning, as some parts of continuity will stay, extra than simply 10%. When a element is named “new,” even a single bolt could make it qualify as such.
The 677, prepared for some weeks now, is predicted to have a nostril just 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 will even be adjustments 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 usually are not anticipated to bear many adjustments, 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 in step 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 ability unit. This space confirmed its shortcomings in the course of the 2024 Formulation 1 marketing campaign, with Enrico Gualtieri, the Technical Director of Energy Unit, pushing onerous to enhance each efficiency and reliability. Engine maps have additionally been optimized for a noticeable achieve in qualifying lap occasions. The Italian media requested for a particular time achieve in tenths, however to keep away from creating expectations, the supply mentioned they’re very optimistic, with a major benefit over the SF-24.
The radiators are anticipated to take care of the identical structure, however some could also be positioned greater, behind the air scoop. It will enable for a centralization of the lots, helpful in dynamic phrases.
