Suzuka underlined Mercedes’ power-unit edge at the start of 2026, and Ferrari accepts the gap. With ADUO rules blocking an immediate hardware fix, the team will push charging-management software and an aero package for Miami while it prepares a larger power-unit concept for later in the season. Charles Leclerc still salvaged a podium in Japan after a safety car setback at Suzuka, but Ferrari leadership and its drivers say the deficit to Mercedes is clear across the first three races.
The team’s read of the early rounds points to deployment and efficiency from the Mercedes power unit as the main difference. Ferrari sees that gap under high load, during energy recovery, and on long runs. The evidence at Suzuka made the point. Race pace held in clean air at times, yet the deployment phase exposed limits. Leclerc and the team stressed that the car needs better energy control to fight at the front on Sundays.
ADUO, the FIA framework governing 2026 engine development, shapes what Ferrari can do next. The rules tie hardware upgrade windows to the measured performance gap. If the gap is within 2 percent, no upgrades are allowed. Between 2 and 4 percent, one upgrade is permitted. Above 4 percent, two are available. The paddock view is that Ferrari sits beyond the 2 percent mark, though internal assessments remain fluid. Even so, the timing and allowances under ADUO restrict an immediate power-unit change.
Ferrari has set its short-term plan around software and aero. The factory’s priority is a major update to charging and energy-management software to stop what the engineers call “super clipping” during recharge. The goal is to stabilize deployment through laps, protect top speed during heavy recovery, and reduce the drop-off seen late on straights. The target event is Miami, with a parallel chassis push to unlock more efficiency from the base car.
On the aerodynamic side, Ferrari has prepared a package for Miami that includes a new “macarena” rear wing, updates to the floor and sidepods, a revised front wing, and diffuser refinements. These parts have cleared CFD and wind-tunnel targets. Track correlation from earlier runs supports the direction. The aim is to cut drag, hold downforce in medium-speed corners, and reduce load sensitivity during battery deployment and recharge.
The testing and validation plan is set. Engineers want on-track sign-off of the software before Miami, using a Monza filming day as a hard test of behavior, cycling through different recharge profiles and deployment maps. If the data matches simulation, the software will go live at Miami. The aero package will arrive there too, with iterative pieces scheduled across Miami and Montreal. The race team will pair set-up work with new energy maps to confirm that software, hardware, and aero are aligned.
Behind the scenes, Ferrari is progressing power-unit concepts for a larger step when the rules and budget windows open. ADUO’s financial allowances and timing mean a new or more substantial unit can be introduced after the sixth race. The plan points to a spec that could be activated around Catalonia in Barcelona if the window and performance gap justify it. That timeline allows Ferrari to bank short-term gains from software and aero while it prepares hardware to match the permitted scope.
The balance of this approach is clear. Software aims to cure deployment losses now, while the aero set adds efficiency that lifts the whole package. The power-unit work continues in the background so the team can act as soon as ADUO permits a change. Ferrari sees Miami as the first checkpoint, Montreal as the follow-up, and the period after race six as the opening to move on the engine side if the gap data supports it.
