The Maranello Formula 1 organization is utilizing a permitted promotional event at Mugello this Wednesday, with both Lewis Hamilton and Charles Leclerc piloting the updated SF-25.
A redesigned rear suspension will be implemented for the 200km of running the squad is allocated for a promotional filming schedule, as Maranello determines whether it can anticipate the concluding portion of the campaign with increased optimism.
This follows the underbody enhancements that signaled improved performance at both the Red Bull Ring and Silverstone, with concentration now projected to transition towards the 2026 regulatory framework with the extensive range of regulation modifications that will yield maneuverable, more compact, narrower, and lighter vehicles.
The assessment at Mugello has been planned before all the components for the Belgian Grand Prix are required to be dispatched to Spa-Francorchamps and will facilitate the acquisition of information pertaining to the renovated suspension prior to the 13th event of the 2025 competition on 25-27 July.
Prior to the construction of the new rear suspension, it was impossible to subject the SF-25 to dynamic analysis, despite its meticulous evaluation via computational fluid dynamics. The principal difficulty involved reducing the leading wishbone of the upper wishbone, pinpointing a juncture on the gearbox capable of enduring the exerted loads.

The transmission’s external structure consists of composite substances to economize on mass and attain the most diminished configuration feasible, featuring membranes of diminished density and purposed reinforcing elements, while in areas designated for the anchoring of the suspension arms, integrations are engineered to endure the pressures induced by a tension rod suspension configuration.
The simulation outcomes were favorable; however, Maranello anticipates that Wednesday’s promotional operation will substantiate analogous indications on the race circuit, consolidating the numerical data with the assessments of the drivers. The innovative suspension assembly is intended to diminish the SF-25’s responsiveness to elevation variations, unlocking advantageous setup possibilities to refine the operational spectrum of the Pirelli tires.
A synchronized influence of the underbody and the suspension could potentially yield a gain of almost a tenth of a second, and should the accumulated information thus far be substantiated, Maranello can endeavor to safeguard its second-place standing in the constructors’ championship, while McLaren remains ahead by a substantial margin of 238 points.

To date, Maranello has been unable to capitalize on opportunities, lacking the position of closest challenger to the MCL39s. The Sauber podium achieved by Nico Hulkenberg during Silverstone serves as evidence, with Hamilton unable to pursue the German driver due to considerable setup challenges encountered by his Maranello vehicle on a humid Silverstone track.
Both Hamilton and Leclerc have addressed forthcoming upgrades, but the discourse will now cease, and the practice sessions at Mugello will determine whether they can at least envision securing a victory this season, an accomplishment already attained by McLaren, Red Bull, and Mercedes at this juncture.
