Ferrari Admits Underestimated Hamilton Challenge as F1 Braces for 2026 Power Unit Drama

Ferrari team principal Fred Vasseur has conceded he "underestimated" the challenge Lewis Hamilton faced in adapting from Mercedes, as Formula 1 faces the prospect of a major protest over an alleged power unit trick at the start of the 2026 season.

Why it matters:

Hamilton's difficult first year at Ferrari highlights the immense pressure and complex transition facing even the most experienced drivers, while the looming power unit controversy threatens to cast a shadow over the sport's new regulatory era before it even begins. Both stories underscore the high-stakes technical and human dynamics that will define the upcoming season.

The details:

• Hamilton's Struggles: Fred Vasseur admitted the team underestimated how challenging the move from Mercedes would be for the seven-time champion, who endured a year plagued by poor results after his high-profile switch.
• Engineer Uncertainty: Ferrari is "evaluating all options" regarding whether Hamilton's race engineer, Riccardo Adami, will continue with him in 2026, signaling potential changes to his support system.
• 2026 Power Unit Dispute: According to Motorsport Magazin, Ferrari, Audi, and Honda have made representations to the FIA over a potential power unit trick allegedly uncovered by Mercedes HPP and Red Bull Powertrains. This could lead to a protest at the 2026 Australian Grand Prix.
• Ferrari's Development Pivot: Charles Leclerc robustly defended Ferrari's "no-brainer" decision to halt 2025 car development as early as April to fully focus on the 2026 rule changes.

The big picture:

These developments paint a picture of a sport in a state of intense preparation and internal tension. Ferrari is navigating the short-term fallout of a high-risk driver signing while betting everything on a long-term regulatory reset. Meanwhile, the technical arms race for 2026 is already generating controversy, suggesting the new rules are fostering innovation that pushes the boundaries of the regulations.

What's next:

All eyes will be on the FIA's response to the power unit allegations and whether it can clarify the rules to avoid a season-opening scandal. For Ferrari, the winter will be crucial in determining Hamilton's engineering lineup and integrating the lessons from his difficult first year into their 2026 project, where expectations will be higher than ever.
