The day after “Lewis Hamilton Day,” Scuderia Ferrari is concentrated on finalizing the final particulars in anticipation of the debut on February 19. Below the technical management of French engineer Loic Serra and the assorted departments, the 677 undertaking ought to function a number of components of continuity and others of great change. The Ferrari 677 might be filled with improvements, with the most recent rumors suggesting adjustments useful for Charles Leclerc and Lewis Hamilton.
Chassis and Suspension
Though the title of the brand new automotive coming from Maranello isn’t but outlined, we are able to verify that the chassis and aerodynamics undertaking has been accomplished for a while. The Maranello staff is at present growing the automotive on dynamic take a look at benches to extract the very best primary setup for the 677. This process is important because of the change to the entrance pull-rod structure, 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 monitor circumstances equivalent to banking, acceleration, braking, and corners, this has allowed the chassis division to raised 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new kinematics pressured a remodelling of the higher and decrease wishbones, aiming to not lose the strengths of the outdated push-rod system. With extra anti-dive (a extra inclined higher wishbone) and a special angle, the Ferrari engineers and technicians intention to take care of braking pressure and efficiency in gradual corners.
On the rear, the adjustments might 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 shocked in 2024 for its big 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 endure important adjustments, with notable modifications to the entrance wing, nostril, and bodywork. Frederic Vasseur‘s statements citing “90% new” needs to be taken with warning, as some components of continuity will stay, extra than simply 10%. When a part is known as “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, connected 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 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.
Via improved and cleaner administration of airflow directed in the direction of the middle of the automotive because of the pull-rod suspension, Ferrari has closely labored on the bodywork. The sidepod inlets will not be anticipated to endure 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 consistent with a administration of the airflow directed to the ground based mostly on the experimental ground 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 change of the facility unit. This space confirmed its shortcomings throughout the 2024 Formulation 1 marketing campaign, with Enrico Gualtieri, the Technical Director of Energy Unit, pushing exhausting to enhance each efficiency and reliability. Engine maps have additionally been optimized for a noticeable achieve in qualifying lap instances. The Italian media requested for a particular time achieve 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 structure, however some could also be positioned larger, behind the air scoop. This may enable for a centralization of the plenty, helpful in dynamic phrases.
