Ferrari fits SF‑26 with Monza parts

Ferrari’s Miami weekend is really about one thing — whether the SF‑26 can turn “promising” into “fast enough.” Ferrari has confirmed it is bringing aerodynamic updates to the car for the Miami Grand Prix after using the long break since Suzuka to study data and run the SF‑26 at Monza on a filming day. The target is obvious. Ferrari has been close early in races, but Mercedes has won all three grands prix so far. Miami is the first real chance to see whether Ferrari’s first in-season package changes that. (motorsportweek.com) ### What actually changed? Fred Vasseur put it plainly before the weekend — Ferrari has “some aero updates” for Miami, and the team spent the gap between races working through data from the opening rounds to prepare them. Ferrari’s own preview framed Miami as a technical reset point for the grid, with multiple teams expected to arrive carrying aerodynamic changes after the long hiatus. (ferrari.com) ### Why does Monza matter here? Because Ferrari did not spend the break just staring at simulation screens. The team used one of its filming days to run the SF‑26 at Monza, and reporting around the Miami package ties those new parts back to that test. A filming day is tightly limited, so it is not a full(ferrari.com)the way the factory tools said it would. (motorsportweek.com) ### What problem is Ferrari trying to fix? The big issue is not that the SF‑26 is slow everywhere. It is that Ferrari has looked competitive in the opening phases of races, then lost that edge over a full distance.

Miami exposes exactly the kind of weaknesses teams hate. The circuit is 5.412 km long, has 19 corners, long straights, heavy braking zones, and hot Florida conditions. Ferrari’s own preview says degradation there is mainly thermal rather than mechanica(motorsportweek.com) quickly. (ferrari.com) ### Does the Sprint format help or hurt? Mostly hurt — at least for a team bringing new parts. Miami is a Sprint weekend, so there is only one practice session before Sprint Qualifying. F1’s schedule page shows FP1 is 90 minutes on Friday, longer than usual, and Ferrari explicitly said making the most of(ferrari.com)ck ride heights, and decide whether every new piece stays on the car. (ferrari.com) ### Are these upgrades a guaranteed step? No — and Ferrari is being pretty careful about that. Vasseur’s tone was measured, basically saying Ferrari has brought updates, but so has everyone else. Lewis Hamilton has also tried to cool the hype around Miami. That is the normal F1 reality: a package can imp(ferrari.com)are still learning fast. (motorsportweek.com) ### So what should we watch for first? Watch Ferrari over a run, not just on one lap. If Charles Leclerc and Hamilton look sharper in the fast direction changes and less vulnerable once tyres heat up, that is the real signal.

It has shown up with its first meaningful answer to Mercedes’ early control of 2026. If the SF‑26’s new aero parts work, Ferrari stops being “best of the rest” and starts making this season uncomfortable for the team in front. (motorsportweek.com)
