Lewis Hamilton has identified two essential areas Ferrari must improve to become a genuine contender for Formula 1 victories in 2027: the SF-26’s successor needs a stronger chassis and aerodynamic package, while the team must also reduce its power unit deficit against its leading rivals. With the final upgrades of the 2026 season introduced at the United States Grand Prix, the seven-time world champion is already working closely with Ferrari’s engineers to influence the design of next year’s car.
The British driver believes the team has reached an important stage in its preparations for 2027, with discussions during the Austin weekend and the remaining races focused on identifying improvements that can be incorporated into components currently being designed. Although the latest SF-26 developments produced encouraging feedback, Hamilton recognises that Ferrari will need more than aerodynamic progress to close the gap to Mercedes and Red Bull.
Lewis Hamilton identifies Ferrari’s main development priorities for 2027
Ferrari’s next Formula 1 car has been under development for some time, but the closing stages of the current championship represent an increasingly important period for refining its technical direction. With fewer opportunities remaining to evaluate the SF-26 in competitive conditions, feedback from the team’s race drivers is becoming particularly valuable.
Lewis Hamilton explained that Ferrari had reached a decisive point in determining the direction of its 2027 project. He confirmed that his work was concentrated on identifying the areas requiring improvement and communicating those priorities to the engineers responsible for designing next season’s components.
According to the seven-time world champion, these discussions were an important part of the United States Grand Prix weekend and would continue at the remaining races. The objective is to ensure that the lessons gathered from the current car are reflected in the next generation of Ferrari machinery.
His involvement is particularly significant because the development process extends beyond providing feedback about the SF-26’s immediate performance. The information gathered during the closing races can help the technical department determine which characteristics should be retained, refined or changed for 2027.
Ferrari’s Austin upgrades provide a foundation for the 2027 F1 car
The United States Grand Prix marked the introduction of Ferrari’s final planned upgrade package for the 2026 season. The team brought a substantial aerodynamic revision to the Circuit of the Americas, incorporating changes to the floor, sidepods and diffuser area.
The developments received positive feedback and provided encouraging indications about the direction of the SF-26. They also created a useful technical foundation for the work already taking place on next year’s car, although the current specification will not simply be carried over unchanged.
Ferrari’s Austin upgrade package and its implications for the Mexico City Grand Prix have already highlighted the importance of understanding how the latest aerodynamic changes perform under different conditions.
Hamilton emphasised that his objective was to guide the engineers towards specific improvements to the chassis and aerodynamic package. Rather than concentrating exclusively on the power unit, the British driver wants the entire car to become more competitive.
This is an important distinction for Ferrari’s development strategy. Even if the team succeeds in reducing its straight-line deficit, achieving consistent victories will also require a chassis and aerodynamic configuration capable of exploiting the available performance across different types of circuits.
Lewis Hamilton believes Ferrari must close its power unit gap to Mercedes and Red Bull
Despite the positive developments introduced in Austin, Ferrari’s engine performance remains one of its most important weaknesses during the 2026 Formula 1 season. The SF-26 has demonstrated competitive chassis characteristics, but the time lost on the straights has repeatedly limited its overall potential.
The problem has been particularly visible when Ferrari has competed directly against Mercedes and Red Bull. Even when the Italian car has shown strong performance through corners, the difference in straight-line speed has made it difficult to convert that advantage into superior lap times.
One illustration came during the United States Grand Prix weekend, when Ferrari’s SF-26 recorded a substantial speed deficit against the Mercedes W17 in the comparison involving Andrea Kimi Antonelli and Charles Leclerc.
However, the recorded speed differences are only one aspect of the performance picture. Straight-line figures can also be influenced by aerodynamic configuration, energy deployment and other operating conditions, meaning they must be considered alongside the broader characteristics of the car.
Hamilton acknowledged that Ferrari’s engineers were working intensively to improve the power unit for next season. He believes that closing the gap to the leading manufacturers in this area would give the Scuderia a realistic opportunity to compete for victories.
The seven-time world champion therefore sees engine development as a potentially decisive factor in Ferrari’s competitiveness. However, his comments also underline the importance of progressing simultaneously with the chassis and aerodynamics, rather than expecting one improvement to resolve every limitation.
How the ADUO system could help Ferrari improve its 2027 engine
Ferrari’s preparations for the next season also involve the opportunities created by the Additional Development and Upgrade Opportunities system, commonly known as ADUO. The framework is designed to provide additional development possibilities for power unit manufacturers that are operating at a performance disadvantage.
For the Maranello team, this mechanism offers an important route towards addressing the weaknesses identified during the first season of the new technical regulations. The power unit represents the area with the greatest potential for improvement, making its development particularly important to Ferrari’s prospects in 2027.
Hamilton has already been closely involved in the discussions surrounding this challenge. The straight-line performance concerns highlighted by his Austin telemetry illustrate why the power unit has become such a significant focus for the Italian manufacturer’s future programme.
Nevertheless, Ferrari’s development work will need to produce gains across several interconnected areas. Improvements in engine performance would strengthen the team’s ability to compete on the straights, while progress with the chassis and aerodynamic package would help determine how effectively that performance can be used over an entire lap.
Ferrari must turn positive Austin feedback into a stronger 2027 package
The final phase of the 2026 season now provides Ferrari with an opportunity to consolidate the progress made through its latest upgrades while gathering feedback for next year. Although the current car is approaching the end of its development cycle, its remaining race appearances can still offer useful information.
Hamilton’s comments also follow a United States Grand Prix in which he encountered recurring balance difficulties that affected his performance. Addressing the car’s limitations therefore remains relevant both to the final races of 2026 and the development priorities for the following championship.
The challenge for Ferrari is to bring together improvements in several different areas. The Austin aerodynamic package offered a positive conclusion to the SF-26’s upgrade programme, but the team must now translate that progress into a more complete car while also pursuing greater power unit performance.
For Lewis Hamilton, the objective is clear. Ferrari must provide its engineers with precise feedback during the remaining races, strengthen the chassis and aerodynamic package, and make substantial progress with its engine. If the team can close the power unit deficit to its rivals, the British driver believes it will have the potential to return to the fight for Formula 1 victories in 2027.
