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 positive aspects each attainable benefit. Enrico Gualtieri, head of the engine division, confirms the presence of reliability modifications, seemingly additionally involving the battery, one of the fragile elements in 2024. Nevertheless, the very absence of main adjustments permits Ferrari to completely perceive its elements, studying the right way to exploit them higher and extract much more energy via a unique rotation of the items all through the season.
Optimized rotation
“Being within the last 12 months of the present energy unit laws, that are frozen, we haven’t modified a lot of our engine,” explains Enrico Gualtieri. “There are some small reliability changes, however they’ll debut proper firstly of the season, and if all the things goes based on plan, we don’t anticipate to introduce additional modifications in the course of the 12 months.” The continuity of the elements 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 enables us to depend on elements of the identical specification from the primary to the final energy unit, whereas in earlier seasons, virtually each time we put in a recent engine, there have been small reliability-related adjustments. Now, within the rotation of energy unit elements all year long, we could have the chance to extract the utmost potential based mostly on the predetermined lifespan of every engine relatively than simply specializing in a single race weekend.”
A traditional instance of engine rotation in the course of the season is utilizing older, much less highly effective energy items in follow periods and/or on road circuits like Monte Carlo. Conversely, races at excessive altitudes, reminiscent of Austria and Mexico, require a recent turbocharger to function at greater speeds and compress the thinner air extra successfully. Ferrari’s intensive expertise with the present energy unit now permits for an much more refined element rotation technique to extract better energy. “In administration, we are able to pay extra consideration to squeezing out each final drop of efficiency,” Enrico Gualtieri explains. “We are going to choose which energy items and even which particular person elements to make use of based mostly on their earlier lifespan, the digital fashions of the elements we have now constructed, and their precise utilization to at all times select probably the most appropriate items for every weekend.”
Each element counts
The completely different rotation technique all year long is made attainable by an influence unit that has remained virtually unchanged since 2024. Enrico Gualtieri continues: “With laws frozen since 2022, we can not bodily modify elements or set up new elements. This doesn’t imply we are able to’t optimize what we have already got. We’ve got tried to adapt our manner of managing the ability unit underneath the assorted circumstances we’d encounter throughout race weekends to maximise its nominal energy. In fact, it’s nothing akin to what we have been used to when improvement was nonetheless open. Nevertheless, it’s one thing we are able to concentrate on to extract each final fraction of efficiency that we could have missed in latest seasons.”
Technical director Loic Serra defined that the objective of the 2025 challenge was to unencumber house for the aerodynamics division. Nevertheless, this work didn’t contain the auxiliary elements of the ability unit, whose structure, based on Enrico Gualtieri, was already optimum: “We haven’t actually modified the set up of the ability unit within the automotive. Already in 2022, we had organized all of the elements within the least intrusive structure, giving the aerodynamics division full freedom to form the bodywork across the minimal footprint of the engine and auxiliary elements. […] We haven’t modified the {hardware}, however we’re at all times seeking to handle the completely 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 System 1, even the smallest fraction of a second makes a distinction.
