Ferrari has brought its third major SF-26 upgrade package of the season to Zandvoort, following the developments introduced in Miami and Barcelona. The latest package features a new floor with changes extending from the inlet section all the way to the diffuser, as the Scuderia targets not only more downforce but also greater aerodynamic robustness across changing conditions.
That quality could prove particularly valuable at the Dutch circuit, where wind can have a significant influence on the car. However, the on-track debut of the new components has been delayed, with Ferrari choosing to complete the opening practice session using the previous specification because of the threat of rain. The package builds on the wider SF-26 aerodynamic upgrade programme for Zandvoort.
Ferrari SF-26 upgrade evolves the existing floor concept
With its third development package of 2026, Ferrari has chosen to evolve and refine solutions already present on the car rather than radically change direction. That approach underlines the team’s confidence in the fundamental SF-26 concept.
The floor inlet, for example, retains its double-entry architecture, a solution that has already influenced McLaren. The main changes for Zandvoort concern the flow conditioners, which now feature a more angular outline and revised curvature.
New SF-26 bargeboards target cleaner airflow
Further outboard, at the front of the floor, Ferrari has introduced new bargeboards designed to manage turbulence generated by the front wheels. The team has returned to the three-element configuration first tested with the Barcelona package before temporarily switching back to a single-element architecture between Austria and Spa.
This time, the outermost fence is shorter and suspended above the floor rather than extending all the way down to it. The outer edge of the floor itself has also been revised as Ferrari continues the detailed aerodynamic refinement of the car, an area that remains central to the team’s wider SF-26 technical development.
Ferrari has also modified the diagonal stay anchored to the chassis that supports the floor. The revised arrangement creates a small slot intended to help clean up the airflow in this area.
Ferrari also changes the diffuser and beam wing
The diffuser has also been updated, making this one of the most extensive areas of the Zandvoort package. Ferrari’s aerodynamic department has revised the shape of the diffuser ramp and its internal fences, although these changes are difficult to appreciate from an external view.
More visible is the new beam wing, the aerodynamic profile positioned immediately above the diffuser. The main modification is concentrated around the area close to the rear crash structure, where the flap now features a more twisted profile than on the previous specification.
Ferrari wants a wider and more predictable SF-26 operating window
As with most aerodynamic development, the work carried out at Maranello is intended to increase downforce and efficiency, but Ferrari is pursuing another important objective with this package. The team has worked to increase the energy of the airflow travelling underneath the floor so that it remains attached to the carbon-fibre surfaces across a broader range of conditions.
In turn, that should reduce the SF-26’s sensitivity to external wind gusts. The ultimate target is to widen the car’s operating window and give its drivers more predictable behaviour behind the wheel, characteristics that could be particularly useful on the exposed and often windy Zandvoort circuit. The weather threat was significant enough for Ferrari to avoid fitting the new components during first practice, protecting them from potential damage while rain remained a risk during the Dutch Grand Prix weekend.
Ferrari hopes these developments can help keep its championship challenge alive, with another significant step also expected later in the season through the updated power unit planned for Monza. For now, the key test will come when the new Zandvoort floor finally makes its track debut and Ferrari can assess whether the aerodynamic improvements deliver the expected gains in real conditions.
