Tech F1i: Ferrari details Bahrain upgrade package for SF-25

Ferrari has arrived in Bahrain with a clear mission: to regain its momentum and challenge its front-running rivals more consistently than it has in the first three races of the 2025 Formula 1 season.

After showing promising signs of pace in pre-season testing but lacking consistency in the opening rounds, the Scuderia has introduced a significant suite of aerodynamic upgrades aimed at refining the performance of the SF-25.

While these changes were not developed specifically for the Sakhir circuit, their implementation this weekend marks a strategic push to improve the car's overall efficiency and balance – crucial attributes on Bahrain’s mix of high-speed straights, long corners, and abrasive surface.

Ferrari’s updates centre primarily around the floor and rear-end aerodynamics, with changes made to the SF-25’s floor fences, body, edge, diffuser, and rear wing.

Ferrari’s engineers have reworked the underfloor airflow, seeking to minimise energy losses and better control the vortex structures that influence diffuser performance.

By refining how air moves beneath the car and exits at the rear, the team hopes to generate more stable downforce and increase cornering grip – two elements that will be vital in combating tyre degradation and maintaining competitive race pace under the Sakhir floodlights and beyond.

As Ferrari leads the charge with the most visible development push this weekend, other teams have also introduced targeted changes.

Red Bull has updated its front wing, extending the chord to increase aerodynamic load and offer greater balance flexibility with different rear wing configurations.

The team has also adapted its cooling package to suit Bahrain’s hot conditions by deploying wider louvre panels.

McLaren has refined the geometry of its front brake duct winglet to enhance flow conditioning and improve overall aerodynamic performance.

Haas, meanwhile, has modified the coke bottle section of its engine cover by enlarging the centre exit to facilitate greater heat expulsion—an option that may only be used based on specific cooling requirements.

While not every team has brought upgrades to Bahrain, those who have are clearly looking to find early-season gains wherever possible.
