For the Japanese Grand Prix, the Ferrari team has worked intensively on further developing the SF-26 in a sustained effort to improve the way energy is deployed and managed over the course of a full lap. Alongside these enhancements, significant attention has also been dedicated to the aerodynamic package of the car, with particular focus on adjustments to the innovative Macarena wing. These modifications are expected to help enhance the overall balance and stability of the SF-26, which remains a crucial factor in achieving consistent lap times and optimal performance across a variety of track conditions.
As Ferrari heads to the Suzuka circuit, the team is looking for clear confirmation of its performance potential. The Maranello-based outfit, widely regarded as the principal alternative to the dominant Mercedes team in the early part of the 2026 Formula 1 season, has prepared for the third round with a significant amount of development work carried out at its factory headquarters. This preparation followed a detailed and meticulous analysis of the data collected from the opening two Grands Prix in Australia and China, which provided critical insights into both the strengths and weaknesses of the current car configuration.
The Suzuka circuit presents a very different and uniquely challenging environment compared to the previously visited tracks, with a layout that emphasizes technical corners, rapid direction changes, and a series of challenging high-speed curves. Suzuka is expected to be particularly demanding in terms of battery energy harvesting, although it is not anticipated to be as extreme as the Melbourne Grand Prix in Australia. Adding to the challenge is the complete resurfacing of the circuit, combined with forecasted cold weather and potentially unstable conditions, which introduces additional uncertainty and could lead to variations from simulation predictions. Teams will need to adapt quickly, as any discrepancy between theoretical models and real-world conditions could significantly influence race strategy and performance.
Back in Maranello, engineers and strategists have been diligently refining the SF-26 package to better exploit the inherent potential of the car, ensuring that the energy harvesting systems are optimized to their maximum efficiency. Early simulation data has provided encouraging signs that the SF-26 can indeed extract more usable energy in critical sections of the lap. However, it remains evident that these improvements are being measured internally and relative to Ferrari’s own benchmarks, without a direct assessment of the performance capabilities of rivals Mercedes. This internal focus ensures that Ferrari maximizes the car’s strengths before attempting to counter the clear advantages demonstrated by its primary competitors.
It is widely acknowledged within the paddock that Ferrari excels in technical and twisty sections of circuits, particularly where cornering speed and vehicle handling play a decisive role. Conversely, the SF-26 tends to encounter difficulties on long, high-speed straights, where the Mercedes power unit, and particularly Kimi Antonelli and George Russell in the W17 cars, can leverage superior high-RPM internal combustion engine power. This allows them to recover more electrical energy efficiently, giving Mercedes a subtle but important advantage in hybrid energy deployment. In simpler terms, the German side sacrifices some fuel efficiency in order to recharge their battery systems more effectively, accepting a minor reduction in overall top speed due to the Super Clipping method, which remains less penalizing than what Ferrari experiences under similar conditions.
Without even taking into account the benefits that can be achieved from a compression ratio that comfortably exceeds 16:1 at full operating temperatures, the Brixworth-built V6 hybrid power unit installed in Mercedes cars has repeatedly demonstrated a distinct advantage in high-speed sections. The Ferrari engineers and technicians are acutely aware of this gap and are developing strategies to mitigate it wherever possible, focusing on optimizing energy recovery, turbo efficiency, and overall deployment patterns to maximize lap performance.
Ferrari’s current approach is based on the belief that the team can achieve a more effective and efficient distribution of energy throughout the entirety of a lap, rather than attempting to directly compete with the Mercedes W17 in its strongest areas. The strategy appears to revolve around pushing Ferrari’s own performance concepts to the extreme, fully exploiting the potential offered by the smaller turbo architecture integrated into the SF-26’s power unit. This approach prioritizes extracting maximum energy in slower corners, transitional sections, and technical parts of circuits, which are the car’s natural strengths, while carefully managing high-speed energy demands.
To achieve this, the Scuderia is aiming to maximize energy accumulation in slower corners and transitional phases, sometimes even using one gear lower in specific circumstances to maintain higher engine revs and enhance battery harvesting efficiency. The power unit team, led by Enrico Gualtieri, has been meticulously optimizing the 067/6 engine to ensure that all available power can be extracted, while simultaneously balancing reliability and thermal management. There is an acknowledgment within the team that the optimal setup for extracting the absolute maximum power from the engine has not yet been fully realized, which leaves room for continuous development and refinement throughout the season.
Although the racing management team has not publicly expressed concerns, it remains a legitimate question whether Ferrari’s fuel partner, Shell, has successfully developed a fuel blend capable of keeping pace with the high-performance Petronas fuel used by the Mercedes-powered cars. At the same time, Ferrari is heavily engaged in aerodynamic development, continuing extensive testing of the Macarena wing on the dynamic rig at Maranello. The dual-movable flap configuration was only briefly seen during a single practice session in China but is very likely to make another appearance during the Japanese Grand Prix weekend, as it plays a significant role in achieving optimal aerodynamic balance.
Questions remain as to why Ferrari has been cautious in fully deploying this solution, despite its clear potential to increase maximum speed in speed trap measurements. During the Shanghai Grand Prix, drivers Charles Leclerc and Lewis Hamilton reported instability in the car’s balance during the closing phase of the movable wing, which made the already critical braking phase even more challenging to manage. In response, Ferrari has explored multiple setup configurations in search of the correct balance, which is especially important for a complex and demanding track such as Suzuka, where precision and stability are key to fast lap times.
Development work has not been limited solely to refining the opening and closing timings of the Macarena rear wing. Aerodynamic engineers have simultaneously been working on front wing adjustments and flap configurations to achieve the necessary equilibrium between front and rear downforce. These parameters cannot be fully replicated in a traditional wind tunnel, and engineers must also assess the reliability of the system under race conditions, including the durability of actuators and mechanical components subjected to high stress over long race distances.
The aerodynamic benefits, clearly visible when the wing is open, are expected to improve further when the wing is closed. However, these gains must outweigh the associated drawbacks. The use of two actuators mounted on the sideplates, replacing the central actuator that would otherwise generate additional drag, inevitably increases the car’s weight. Ferrari is also working to reduce the SF-26’s overall weight, as the current configuration carries an excess of approximately 6–7 kilograms that could be eliminated to improve handling and efficiency.
The version of the Macarena wing seen so far represents only the first stage of its ongoing development. A more sophisticated concept is currently being evaluated, one that would allow for differentiated closing timings depending on the specific corners that the car must navigate. This advanced approach aims to provide Ferrari with the flexibility to adapt energy harvesting and aerodynamic balance to the precise demands of each circuit, offering a competitive advantage in strategic deployment.
This phase of development is only the beginning, and it is expected that the cars will undergo significant visual and technical changes throughout the season. It is also possible that the small plastic aerodynamic element previously mounted on the Halo support in China, which was present up until the Sprint race and then removed to avoid potential issues, could return in a revised form. Its declared function as a windscreen raised concerns about driver visibility, and a modified, potentially more transparent version could be introduced, addressing both FIA requirements and rival team objections, some of whom were reportedly prepared to submit a formal protest.
Ferrari is therefore not yielding to the clear superiority of the silver and black Mercedes cars. The Japanese Grand Prix will provide an important test of whether the current development trajectory is correct. Following this event, there will be a one-month break in the calendar due to the cancellation of the Bahrain and Jeddah rounds, offering the team a crucial opportunity to consolidate its development gains, refine the SF-26, and attempt to close the performance gap to its primary rivals in the 2026 Formula 1 championship.
