Lewis Hamilton exposes Ferrari’s weaknesses: what he wrote in his confidential documents to the Maranello team. Lewis Hamilton has submitted a detailed internal report to Ferrari, highlighting critical weaknesses in the SF-25.

Seven-time Formula 1 world champion Lewis Hamilton has reportedly submitted a comprehensive internal report to the Ferrari team, detailing key weaknesses that must be addressed if Scuderia Ferrari is to return to the front of the Formula 1 grid.

Having been officially part of the Ferrari family for nearly seven months now, Lewis Hamilton’s start with the legendary Italian racing team has been far from smooth. The 2025 Formula 1 season has thus far brought more lows than highs for the British driver. While part of the struggle stems from the lack of competitiveness of the SF-25 single-seater, another contributing factor has been Hamilton’s ongoing difficulties in adapting to Ferrari’s working environment and the car’s unique handling characteristics.

According to reports, including insights from RacingNews365 technical analyst Paolo Filisetti, Lewis Hamilton has compiled and delivered a number of detailed internal documents to the team. These documents reportedly cover at least three key areas, each of them addressing fundamental structural and technical issues within Ferrari.

One of the central focuses of Hamilton’s analysis was the current technical and organizational structure of the Scuderia. He reportedly highlighted various inefficiencies and limitations within Ferrari’s workflow, especially those affecting the 2025 SF-25’s performance. He also included his input and expectations for the development direction of the 2026 Formula 1 car. According to Filisetti, Hamilton’s review extended beyond just the technical department and covered the performance of multiple groups working across the Maranello factory.

The British driver, who previously spent his entire F1 career within the British-based environments of McLaren and Mercedes, noted that Ferrari’s culture and operations differ significantly. His evaluation found that the existing development model within Ferrari tends to lack agility and suffers from communication gaps between departments. Hamilton reportedly advocated for a more streamlined and proactive approach to development that would allow Ferrari to keep pace with faster-moving rivals like McLaren and Red Bull Racing.

Currently, Ferrari often develops multiple concepts in parallel but only commits to one after late-stage validation. Hamilton’s suggestion was to implement a more dynamic and flexible structure—one that makes earlier decisions based on clear performance indicators, thereby avoiding the delays that can result from an overly cautious approach.

Hamilton also raised concerns shared by his teammate Charles Leclerc, particularly around the SF-25’s behavior in high-speed corners. Both drivers have pointed to unpredictable aerodynamic and mechanical balance, which undermines their ability to consistently push the car to its limits. Hamilton, who joined Ferrari in search of a new challenge and an eighth world championship, is said to be frustrated by how little feedback from the car translates into clear performance adjustments.

He emphasized the difficulty of interpreting the car’s reactions to various setup changes, calling the SF-25 “inconsistent” in its behavior—an issue he feels has significantly limited his understanding of how to extract maximum performance. This unpredictability has made it harder for him to adapt his driving style and build confidence in the car.

Another major theme of Hamilton’s internal assessment involved improving the efficiency and preparation of Ferrari’s race weekends. He reportedly recommended changes to how the team plans its trackside operations, particularly in terms of making faster and more effective setup decisions during practice sessions. According to Lewis Hamilton, Ferrari must enhance its weekend structure, with better pre-event simulations and more decisive adaptation to track conditions if it wants to fight consistently for podiums and victories.

Looking ahead to the 2026 Formula 1 regulations, Hamilton has also made clear his expectations for the next generation of Ferrari cars. He is said to be pushing for a car that offers better balance between front and rear stability, and one that avoids the extremes of setup experimentation. What he wants, in essence, is a more refined and progressive development approach—one that results in a car that is predictable, consistent, and competitive without requiring radical design risks.

In summary, Lewis Hamilton has not only highlighted Ferrari’s current weaknesses but also outlined a clear and ambitious roadmap for the team’s recovery. From technical structures and development processes to race weekend execution and future car design, Hamilton’s influence is already reshaping the Scuderia’s internal dynamics. The big question is whether Ferrari will be able to act swiftly on this feedback—and whether the changes will come in time to give the British champion the tools he needs to fight at the front once again.
