Ferrari will roll out a heavily revised power unit software package for the Miami Grand Prix at the Miami International Autodrome and will use a Monza filming day on April 21 or 22 to validate that package. The team will also test a new floor and an evolved Macarena rear wing at Autodromo Nazionale Monza. The plan is part of a push to close the gap to Mercedes while McLaren shows stronger form.
The power unit program is split in two. Miami will get a software-only update focused on energy deployment and harvesting algorithms. Ferrari is aiming to improve how the car stores and releases electrical energy over a lap. A larger hardware and spending step is tied to the ADUO process and can be applied only after the ADUO cutoff. That phase is likely to land for Barcelona or after Monaco. It still depends on F1 Commission approval and the formal power unit ranking.
The Monza filming day, limited to 200 km, is central to the plan. Ferrari will run the revised software on a track that puts a heavy load on energy recovery. The team will also trial the revised floor, the next iteration of the Macarena rear wing, and rebuilt halo vanes that were previously removed for compliance. Data from Monza will decide what can race as early as Miami and what will move to Canada.
The aerodynamic work is broad. The new floor targets more downforce across a range of ride heights. The Macarena v2 rear wing aims to improve stability and save weight. Front wing tweaks, cooling changes, and lighter components are also in the pipeline. Ferrari wants some of these parts ready for Miami, with others no later than Canada if validation is positive.
The rollout has been compressed. The cancellations of the Bahrain and Saudi rounds forced Ferrari to change its original step-by-step plan. The team has had to pick which parts can be checked and raced within the limits of a sprint-format weekend in Miami, where practice time is short and setup windows are tight.
Context matters. Ferrari is reported to be down about 2 percent, roughly 20 bhp, to Mercedes on power. McLaren has also been strong at recent events. That puts weight on clean execution in Miami and clean testing at Monza. If the software gains show up and the aero package validates, Ferrari will bring the first batch to the car. The second phase will wait for the ADUO window and the green light from the sport’s governance.
