The event freeze imposed in 2022 has prevented Ferrari from updating the ability unit, however the Maranello workers has nonetheless labored to make sure the SF-25 features each attainable benefit. Enrico Gualtieri, head of the engine division, confirms the presence of reliability modifications, seemingly additionally involving the battery, one of the crucial fragile parts in 2024. Nevertheless, the very absence of main adjustments permits Ferrari to totally perceive its parts, studying the right way to exploit them higher and extract much more energy by a distinct rotation of the items all through the season.
Optimized rotation
“Being within the ultimate 12 months of the present energy unit rules, that are frozen, we haven’t modified a lot of our engine,” explains Enrico Gualtieri. “There are some small reliability changes, however they are going to debut proper at first of the season, and if the whole lot goes in response to plan, we don’t anticipate to introduce additional modifications through the 12 months.” The continuity of the parts ensures stability for Ferrari, which, with fewer variables, can leverage the information gathered on particular person elements to plan their utilization extra successfully.
The Italian engineer continues: “This permits us to depend on parts of the identical specification from the primary to the final energy unit, whereas in earlier seasons, virtually each time we put in a contemporary engine, there have been small reliability-related adjustments. Now, within the rotation of energy unit parts all year long, we may have the chance to extract the utmost potential primarily based on the predetermined lifespan of every engine somewhat than simply specializing in a single race weekend.”
A basic instance of engine rotation through the season is utilizing older, much less highly effective energy items in observe periods and/or on road circuits like Monte Carlo. Conversely, races at excessive altitudes, reminiscent of Austria and Mexico, require a contemporary turbocharger to function at increased speeds and compress the thinner air extra successfully. Ferrari’s intensive expertise with the present energy unit now permits for an much more refined part rotation technique to extract larger energy. “In administration, we will pay extra consideration to squeezing out each final drop of efficiency,” Enrico Gualtieri explains. “We’ll choose which energy items and even which particular person elements to make use of primarily based on their earlier lifespan, the digital fashions of the parts we’ve constructed, and their precise utilization to at all times select essentially the most appropriate items for every weekend.”
Each element counts
The totally different rotation technique all year long is made attainable by an influence unit that has remained virtually unchanged since 2024. Enrico Gualtieri continues: “With rules frozen since 2022, we can not bodily modify elements or set up new parts. This doesn’t imply we will’t optimize what we have already got. We now have tried to adapt our method of managing the ability unit underneath the assorted circumstances we would encounter throughout race weekends to maximise its nominal energy. In fact, it’s nothing akin to what we had been used to when growth was nonetheless open. Nevertheless, it’s one thing we will deal with to extract each final fraction of efficiency that we might have missed in current seasons.”
Technical director Loic Serra defined that the aim of the 2025 challenge was to unlock house for the aerodynamics division. Nevertheless, this work didn’t contain the auxiliary parts of the ability unit, whose structure, in response to Enrico Gualtieri, was already optimum: “We haven’t actually modified the set up of the ability unit within the automobile. Already in 2022, we had organized all of the parts within the least intrusive structure, giving the aerodynamics division full freedom to form the bodywork across the minimal footprint of the engine and auxiliary parts. […] We haven’t modified the {hardware}, however we’re at all times seeking to handle the totally different cooling wants that will come up from aerodynamicists’ necessities or future setup selections.”
A meticulous effort by Ferrari’s engine division, however in such a finely balanced Method 1, even the smallest fraction of a second makes a distinction.
