Ferrari’s steady rise throughout the 2026 Formula 1 season appears to be far from over. While recent aerodynamic developments have already helped close the gap to Mercedes, the team is now preparing what could become its most significant technical breakthrough of the year: a comprehensive power unit upgrade designed to unlock even more performance from the SF-26.
The Italian team may still be chasing Mercedes in both world championships, but Ferrari’s relentless development programme has established the Scuderia as one of the most aggressive teams on the grid. Rather than slowing development as the season progresses, engineers in Maranello continue pushing forward with new solutions aimed at giving both Lewis Hamilton and Charles Leclerc the tools needed to consistently fight for victories.
Since the introduction of Formula 1’s latest technical regulations, Ferrari have brought four major upgrade packages to the SF-26, supported by a series of smaller refinements targeting different areas of the car. The philosophy has been clear: make continuous gains across every aspect of the package instead of relying on one dramatic performance leap.
Recent upgrades have already changed the SF-26
The progress achieved over the last few races has been evident on track.
At the British Grand Prix, Ferrari introduced several important updates, including a redesigned rear corner assembly, revised aerodynamic winglets and an updated rear wing. Together, those changes improved the car’s aerodynamic efficiency while also increasing straight-line performance—an area where the Italian side had often struggled against Mercedes earlier in the season.
Both Lewis Hamilton and Charles Leclerc immediately benefited from the improvements, allowing Ferrari to become significantly more competitive at one of the fastest circuits on the Formula 1 calendar. The stronger overall balance also gave both drivers greater confidence when attacking high-speed corners, an encouraging sign that the development direction chosen by the engineering team is delivering the expected results.
However, Ferrari believe those gains represent only the beginning of a much broader development programme.
A new power unit is now taking shape
One of Ferrari’s biggest priorities remains improving the performance of the SF-26’s power unit.
Earlier this season, the FIA’s ADUO development initiative granted manufacturers additional opportunities to refine specific engine components. Ferrari immediately took advantage of one of its available development tokens during the Austrian Grand Prix weekend, focusing on extracting additional performance from a power unit that has occasionally lacked the outright speed of its main rivals.
Lewis Hamilton has previously acknowledged that straight-line performance has been one of the Maranello team’s weakest areas during several races this year. Closing that gap could therefore unlock even greater potential from a chassis that many inside the paddock already consider among the strongest in Formula 1.
According to a report from SoyMotor, Ferrari’s power unit specialists and chassis engineers are now working closely together on the next major phase of the SF-26 project. The objective is not simply to add horsepower, but to ensure that every element of the car works together more efficiently, following the technical philosophy introduced by Technical Director Loïc Serra at the beginning of the 2026 programme.
Ferrari planning double upgrade after the summer break
Although Ferrari have not officially confirmed the exact timetable, reports suggest that the next major aerodynamic package is expected to debut shortly after the summer break, most likely during the Dutch Grand Prix weekend.
The engine upgrade is also expected to arrive around the same period, allowing Ferrari to introduce two significant performance improvements within a relatively short timeframe.
Bringing both developments together could provide a substantial boost during the closing stages of the championship, when every tenth of a second becomes increasingly valuable in the battle against Mercedes.
Rather than treating the chassis and power unit as separate projects, Ferrari are reportedly developing both upgrades simultaneously to maximize the overall performance gain. That integrated approach has become increasingly important under Formula 1’s current technical regulations, where improvements in one area often influence the effectiveness of another.
Confidence continues to grow inside Maranello
The atmosphere within Ferrari has reportedly changed dramatically over recent weeks.
Victories for both Lewis Hamilton and Charles Leclerc have injected fresh confidence throughout the Maranello factory, reinforcing the belief that the team’s development strategy is moving in the right direction.
According to the Spanish report, engineers working on the SF-26 are convinced that Ferrari’s strongest performances have not yet been seen. Several members of the technical department reportedly believe that the team’s biggest gains are still ahead, describing the current mood inside Maranello as extremely optimistic following the recent improvements.
That confidence is being driven not only by the race results but also by the encouraging data emerging from the Italian side’s ongoing development programme, with engineers increasingly convinced that further upgrades will allow the SF-26 to exploit its full potential.
Could the engine be Ferrari’s final missing piece?
Throughout much of the season, many observers have argued that Ferrari already possess one of the most complete chassis packages on the grid. The remaining weakness has often been identified as the power unit, particularly on circuits where straight-line speed plays a decisive role.
If Ferrari succeed in bringing their engine performance closer to that of Mercedes without sacrificing reliability, the balance of power could shift considerably during the second half of the championship.
For Lewis Hamilton, the arrival of additional engine performance could provide exactly the weapon needed to sustain his challenge in the Drivers’ Championship. Charles Leclerc would equally benefit from improved acceleration and higher top speed, giving Ferrari two genuine contenders capable of consistently fighting at the front.
With major aerodynamic updates, a revised power unit and growing confidence throughout the factory, Ferrari are entering one of the most important phases of the 2026 Formula 1 season. If the upcoming developments perform as expected, the Scuderia may finally have everything required to mount its strongest championship challenge in nearly two decades.
