The day after “Lewis Hamilton Day,” Scuderia Ferrari is concentrated on finalizing the final particulars in anticipation of the debut on February 19. Beneath the technical management of French engineer Loic Serra and the assorted departments, the 677 undertaking ought to function a number of parts of continuity and others of great change. The Ferrari 677 will likely be filled with improvements, with the most recent rumors suggesting modifications helpful for Charles Leclerc and Lewis Hamilton.
Chassis and Suspension
Though the title of the brand new automotive coming from Maranello just isn’t but outlined, we will verify that the chassis and aerodynamics undertaking has been accomplished for a while. The Maranello staff is presently creating the automotive on dynamic take a look at benches to extract the perfect primary setup for the 677. This job is important as a result of change to the entrance pull-rod format, which has required extra studying time than anticipated, with the previous Mercedes driver overseeing your entire dynamic take a look at.
Positioned on the dynamic take a look at bench, which simulates the numerous monitor circumstances reminiscent of banking, acceleration, braking, and corners, this has allowed the chassis division to higher 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new kinematics compelled a remodelling of the higher and decrease wishbones, aiming to not lose the strengths of the outdated push-rod system. With extra anti-dive (a extra inclined higher wishbone) and a special angle, the Ferrari engineers and technicians goal to keep up braking drive and efficiency in sluggish corners.
On the rear, the modifications will likely be minor however nonetheless current. As a result 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 stunned in 2024 for its big 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 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 modifications, 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 part 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 much 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 may 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 automotive as a result of 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 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 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 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 occasions. The Italian media requested for a particular 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 keep up the identical format, however some could also be positioned increased, behind the air scoop. It will permit for a centralization of the plenty, helpful in dynamic phrases.
