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 varied departments, the 677 challenge ought to characteristic a number of parts of continuity and others of great change. The Ferrari 677 might be stuffed with improvements, with the newest rumors suggesting adjustments helpful for Charles Leclerc and Lewis Hamilton.
Chassis and Suspension
Though the title of the brand new automobile coming from Maranello shouldn’t be but outlined, we are able to affirm that the chassis and aerodynamics challenge has been accomplished for a while. The Maranello workforce is presently creating the automobile on dynamic check benches to extract the perfect primary setup for the 677. This activity is important as a result of change to the entrance pull-rod structure, which has required extra studying time than anticipated, with the previous Mercedes driver overseeing your complete dynamic check.
Positioned on the dynamic check bench, which simulates the various observe situations similar 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new kinematics pressured a remodelling of the higher and decrease wishbones, aiming to not lose the strengths of the outdated push-rod system. With extra anti-dive (a extra inclined higher wishbone) and a special angle, the Ferrari engineers and technicians goal to take care of braking pressure and efficiency in gradual corners.
On the rear, the adjustments might be minor however nonetheless current. Because 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 aspect, the brand new Ferrari single-seater for the 2025 Method 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 important 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 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 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 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 means of improved and cleaner administration of airflow directed in direction of the middle of the automobile as a result of 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 direction of the undercut is extra open on the 677. That is in step with a administration of the airflow directed to the ground based mostly on the experimental ground 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 change of the facility unit. This space confirmed its shortcomings in the course of the 2024 Method 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 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 mentioned 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 increased, behind the air scoop. This may permit for a centralization of the plenty, helpful in dynamic phrases.
