The Ferrari SF-26 is already regarded as one of the most complete Formula 1 cars at this stage of the 2026 season. Its aerodynamic potential is particularly impressive through long, high-load corners, while braking has emerged as another benchmark area. The clearest room for improvement remains elsewhere: low-speed acceleration, rear-tyre thermal management on rear-limited circuits and the performance of the internal-combustion side of the power unit.
Zandvoort, Monza and Austin will provide three very different but equally important tests of how far the SF-26 can ultimately go. Ferrari’s third major aerodynamic package of the season is expected in the Netherlands, followed by the ADUO 2 power-unit step at Monza and another development currently planned for Austin. Together, those upgrades are intended to improve efficiency, power delivery and the overall completeness of a car that already possesses several class-leading qualities.
Ferrari SF-26 chassis already excels in high-load corners and braking
Placing the SF-26 in an exact performance hierarchy remains difficult because its strengths and weaknesses vary considerably with circuit characteristics. In long corners and high-load sections, however, the Ferrari displays qualities worthy of the very best cars on the grid. It combines a precise front end with well-distributed aerodynamic load and impressive speed once the car is settled into a sustained corner.
Braking performance is another major strength. The stability of the Maranello car under heavy braking allows Charles Leclerc and Lewis Hamilton to attack corner entry without necessarily compromising the following phase of the turn. These characteristics form an important part of why the SF-26 is already considered such a strong chassis package and reinforce the wider picture outlined in ScuderiaFans’ analysis of Ferrari’s key SF-26 development priorities.
The more significant limitation tends to emerge afterwards, when the driver must complete the rotation of the car and transfer torque rapidly to the rear wheels. Through slow corners, Ferrari does not always convert the quality of its corner entry into an equally competitive exit.
Rear traction and tyre temperatures remain key Ferrari weaknesses
On rear-limited circuits, the combination of lateral load and longitudinal demand can generate more tyre slip than Ferrari would ideally want. That sliding raises the temperature of the rear tyres, reduces available grip and forces the driver to become more cautious when applying the throttle.
Over a single lap, the SF-26 can still display extremely high potential because the driver only needs to extract maximum performance for a relatively short period. Over a race stint, however, repeatedly producing the same quality of corner exit becomes more difficult. The car loses effectiveness when it has to apply significant torque again and again without pushing the rear tyres beyond their optimum thermal window.
The situation is compounded by the delay associated with the internal-combustion side of the power unit. A slower exit prolongs the acceleration phase and amplifies the performance deficit, which means engine performance and traction cannot be analysed independently. More power is useful only if the chassis, tyres and rear axle can translate that torque into effective acceleration.
This interaction between aerodynamic performance, setup and tyre behaviour is one of the reasons Ferrari’s technical challenge extends beyond simply adding downforce or horsepower. The Ferrari technical analysis archive provides further context on the different areas that have shaped the SF-26 throughout the 2026 campaign.
Zandvoort upgrade must widen the Ferrari SF-26 operating window
Zandvoort could suit the characteristics of the SF-26 particularly well. Long loaded corners, high aerodynamic demand and sustained lateral forces should play to the strengths of Ferrari’s front end and chassis. At the same time, the Dutch Grand Prix will provide a severe examination of the third major aerodynamic package of the season.
The circuit’s banking, wind sensitivity and elevation changes continuously alter the conditions in which the car has to generate aerodynamic load. Ferrari’s objective therefore cannot simply be to increase the maximum amount of downforce available. The new package also needs to improve the transition between the car’s cornering configuration and its lower-drag state.
ScuderiaFans has already detailed how Ferrari has accelerated its new SF-26 floor programme for Zandvoort, making the Dutch weekend an especially important technical checkpoint. The full weekend information is also available in the 2026 Dutch Grand Prix schedule and Zandvoort guide.
For the SF-26 to become the outright reference, the package should provide a usable improvement in the region of two tenths of a second per lap. More importantly, Ferrari needs that advantage to be repeatable throughout a stint. A consistent improvement over several laps would carry greater value than an isolated performance peak produced only on a single qualifying lap.
Monza and ADUO 2: why ten horsepower could matter
At Monza, the competitive priorities will change dramatically. Power, drag, braking performance and traction out of the chicanes will become central. Heavy braking should again favour Ferrari, but the challenge will be converting that strength into speed on corner exit without overheating the rear tyres.
Active aerodynamics will not eliminate the requirement for an efficient car. The straight-line configuration will reduce the resistance generated by the wings, but the body of the car will continue to produce drag. Ferrari therefore needs both an efficient chassis and greater power if it wants to exploit the SF-26 fully on Monza’s long straights.
The first ADUO update introduced in Austria was worth seven horsepower. The second step, expected for Monza, is indicated at a minimum of ten horsepower, equivalent to approximately 7 kW. Provided reliability is not compromised, the benefit could amount to slightly more than one tenth of a second at Monza and a somewhat smaller gain at Baku.
The planned step forms part of Ferrari’s broader Monza power-unit upgrade programme, but ten additional horsepower alone will not transform the SF-26 into Formula 1’s new benchmark.
More Ferrari power will only help if the SF-26 can use it
Additional engine performance cannot solve the traction limitation by itself. A more powerful engine can improve acceleration only if the car is capable of transferring that additional torque effectively to the asphalt. If Charles Leclerc or Lewis Hamilton has to delay opening the throttle to control rear-wheel slip, part of the theoretical benefit from the power increase is immediately lost.
ADUO 2 could therefore free up the SF-26 on the straights, but Ferrari needs to achieve that without increasing the thermal load placed on the rear tyres. The nominal horsepower figure only tells part of the story.
At Monza, another decisive factor will be how long Ferrari can maintain full electrical assistance along the straights. If deployment is exhausted before the braking zone, part of the improvement provided by the internal-combustion engine would effectively be neutralised.
Performance will consequently depend on the quality of the integration between combustion, energy recovery and management of the hybrid system. This is particularly important because deployment itself has become a major performance factor in the current technical era. Ferrari has already been working on precisely these details as part of its wider effort to refine the complete SF-26 package.
Austin development could complete the Ferrari SF-26
The next development currently planned for Austin could prove even more significant. Circuit of the Americas combines fast Esses, heavy braking zones, slow corners and an uneven track surface, making it an ideal venue to discover whether Ferrari has truly completed the SF-26 as an all-round package.
The heavy braking areas and the opening sector should favour the car’s established strengths. The greater challenge will be ensuring that its balance remains coherent throughout the lap and that the rear axle receives more consistent support when the driver returns to the throttle.
On bumps, a temporary reduction in vertical load can trigger tyre slip. That sliding can increase surface temperature and compromise traction, placing even greater importance on the way the suspension, aerodynamics and tyres work together. The Austin upgrade must therefore help make the SF-26 more predictable and effective precisely in the phase where it currently has the greatest room for improvement.
The three races will consequently perform different diagnostic roles. Zandvoort will measure the effectiveness of the aerodynamic package, Monza will test the new power and Austin should reveal the overall completeness of the car.
Any performance comparison will remain relative rather than absolute. Gaining half a second does not automatically mean Ferrari has recovered half a second relative to Mercedes, because its rivals will continue developing their own cars as well. In Formula 1, the relevant measurement is always how quickly one team progresses compared with the opposition.
Which circuits could favour the Ferrari SF-26?
The remaining calendar presents both opportunities and risks. Zandvoort, Qatar, if it takes place, and Austin should reward the SF-26’s aerodynamic performance, front-end precision and speed through loaded corners. However, the prolonged stresses at those tracks would also require careful management of rear-tyre temperatures.
Monza, Sepang and Las Vegas could benefit from ADUO 2 and Ferrari’s strong braking performance. Monza and Las Vegas will also test efficiency in the straight-line configuration, where the SF-26 will need low drag while retaining sufficient electrical energy deployment through to the end of the fastest sections.
Fans can follow how these very different circuit types fit into the championship through the complete 2026 Formula 1 calendar.
Singapore and Baku will be particularly demanding for traction. Mexico’s altitude will complicate cooling and aerodynamic load, while Baku represents an especially interesting compromise. Its very long straight should reward ADUO 2 and Ferrari’s braking strength, but the slow corners will continue to put the rear tyres under pressure.
Abu Dhabi or Imola would pose very different final tests
Abu Dhabi would also represent a delicate examination of the SF-26. The slow acceleration zones in the final sector, combined with the energy repeatedly transferred through the rear tyres during a stint, would bring traction and overheating back into focus. The straights would favour the upgraded power unit, but they would not erase the underlying mechanical limitation.
If the season finale were instead transferred to Imola in December, the technical picture could become more favourable for Ferrari. Medium-speed corners, changes of direction and major braking zones would play to the SF-26’s aerodynamic load, precise front end and braking stability while reducing its exposure to repeated slow-speed acceleration.
Cold conditions could help contain rear-tyre overheating, although they would create the opposite risk. Bringing the tyres up to temperature could become more difficult, while graining could emerge as another concern, particularly after a neutralisation period.
On a cold but dry circuit, Imola could therefore become one of the strongest opportunities for the SF-26. With extreme temperatures or significant humidity, however, any expected advantage would become far less certain.
Ferrari needs three final steps to make the SF-26 the benchmark
Ferrari already possesses one of the strongest cars of the 2026 season. The SF-26 is highly competitive in high-load corners, has a precise front end and stands among the references under braking. Its main limitation appears after corner entry, when the driver has to complete the rotation, apply torque and keep the rear tyres within the correct thermal window.
Three key steps could determine whether the car becomes the outright benchmark during the second half of the season. Ferrari needs to widen the aerodynamic operating window at Zandvoort, reduce the internal-combustion delay through the ADUO 2 engine update at Monza and then improve traction and rear-end management with the development planned for Austin.
Braking performance is already a major weapon, while the upgraded power unit can unlock additional straight-line speed and potentially create more freedom in how the car is set up. Yet outright horsepower will not be the final deciding factor.
The crucial test will be whether Ferrari can convert torque into acceleration without overheating the rear tyres. If the Maranello team can combine the existing strengths of the SF-26 chassis with stronger power delivery, more consistent traction and improved rear-tyre management, it could have the ingredients required to become the most complete car of the second half of the 2026 Formula 1 season.
