Leclerc: Ferrari needs ADUO boost to close power unit gap

Charles Leclerc has effectively confirmed what many suspected: Ferrari's SF-26 may be a decent chassis, but its power unit is not keeping pace with Mercedes and Red Bull-Ford. Ahead of the Canadian Grand Prix, the Monegasque openly acknowledged the Scuderia's recurring struggles on the straights, casting doubt on their title hopes under the radically different 2026 regulations.

Why it matters:

With Formula 1's new rules placing unprecedented emphasis on the hybrid powertrain, engine performance has become the decisive factor. Ferrari's apparent horsepower disadvantage threatens to derail a season that started with promise, making the FIA's new balancing mechanism—ADUO—their best hope for leveling the playing field.

The Details:

• Leclerc stated that Mercedes has a "very big advantage" and he'd be "surprised" if Ferrari doesn't qualify for ADUO upgrades, seeing the deficit on straights.
• The FIA's Additional Development and Upgrade Opportunities system allows trailing manufacturers to make engine upgrades after the first definitive performance assessments, which occur after Montreal.
• Ferrari's SF-26 showed early pace in Melbourne, Shanghai, and Suzuka, but faded over long stints as Mercedes and Ford power units pulled ahead.
• Miami updates brought marginal gains, but McLaren's upgrade package delivered a much larger step forward, highlighting the rapid development race.
• Leclerc emphasized that raw upgrades are only part of the story: optimization of the deeply interconnected systems—chassis, aerodynamics, electrical deployment, engine efficiency—is equally crucial.
  • He noted Red Bull's strong winter test performance, then struggles, then recovery in Miami, attributing the swing partly to optimization rather than just new parts.

What's next:

Ferrari hopes ADUO approval will provide a targeted horsepower boost, but the development war is accelerating. Leclerc believes gains from new parts are currently larger than under previous regulations, making the coming months decisive. If Maranello can unlock performance through optimization alongside any ADUO upgrades, they may still close the gap—but the clock is ticking.
