Nearly every team on the grid has brought technical upgrades for this weekend’s Spanish GP in response to newly enforced FIA front wing load tests.
These updates are designed not only to meet the regulatory requirements introduced to reduce excessive flexing but also to enhance aerodynamic performance at this high-downforce venue.
While McLaren is the sole team to arrive in Spain without submitting new parts – having already trialed its revised front wing in Imola – all other outfits have made alterations across a range of components.
Here's a detailed, team-by-team breakdown of the upgrades introduced for the Spanish Grand Prix:
Ferrari Ferrari has brought a significantly reworked front wing to Barcelona, aiming to optimize the chordwise and spanwise loading across the wing’s elements. These changes also extend to a redesigned endplate and modified outboard tip rolls, improving both aerodynamic efficiency and load compliance.
At the rear, the team has introduced a circuit-specific rear wing with a revamped outboard tip and roll, tailored to match the high-downforce demands of the Spanish track.
Red Bull Red Bull has taken the opportunity to revise its front wing with modifications to the first and second elements, primarily in their cross-sectional geometry. These changes have led to consequential adjustments to the flap elements and tip areas, ensuring the new assembly meets FIA load tests while maintaining Red Bull’s high aerodynamic standards.
Mercedes Mercedes arrives in Spain with a trio of aerodynamic updates. The most notable is a redesigned floor edge that now features increased chord and additional vanes, improving local airflow management. Accompanying this is a reprofiled inboard floor fence, designed to better condition airflow beneath the car.
At the rear, the mainplane and flap elements of the rear wing have also been reprofiled to enhance performance under the updated aero regulations.
Aston Martin Aston Martin’s front wing update includes refined tip details between the wing elements and endplate, contributing to more stable airflow.
The main wing sections themselves have also been reshaped to comply with FIA technical directive TD018H, ensuring both legality and aerodynamic gain as the team looks to rebound from a challenging first half of the season.
Alpine Alpine has implemented floor changes aimed at improving downforce and flow consistency. The reprofiled floor fences will help manage vortex generation more effectively, while local adjustments to the floor body itself aim to optimize airflow underneath the car, contributing to improved balance and grip.
Haas Haas has opted to update the construction of its front wing, a change driven by the need to adapt mechanically to the FIA's new deflection standards. The revision is expected to bring both compliance and subtle aerodynamic gains, aiding the team’s search for more consistent qualifying and race pace.
Racing Bulls Racing Bulls have launched a comprehensive front-end update. The new front wing features a lower central section to improve airflow to the floor, and the connection between the wing tips and endplates has been adjusted to fine-tune vortex control.
Additionally, the nose has undergone modifications, with its lower surface raised and tip lowered, enhancing aerodynamic flow conditioning across the car’s front section.
Williams Williams has updated its front wing assembly to meet the FIA’s latest deflection standards. In doing so, they also revised the geometry of the rearward flap and the front wing endplate, with a more conservative outboard profile and camber changes to the endplate's vertical section.
At the rear, the team has tweaked the brake duct’s exit to optimize airflow, and a new cooling louvre panel with the maximum number of large openings has been added for thermal management.
Sauber Sauber has introduced several changes to its floor package. These include updates to the floor fences, outboard floor edge, and diffuser, all aimed at refining local load distribution and increasing underbody aerodynamic efficiency without compromising the car’s compliance with the updated FIA regulations.
McLaren McLaren has made no new submissions this weekend. The team had already debuted its updated front wing earlier in the season at Imola and did not require further regulatory sign-off from the FIA, indicating that their upgrade path remains ahead of schedule.
With temperatures set to rise and teams navigating an increasingly complex development war, this weekend’s round of racing in Barcelona may offer the clearest insight yet into which teams have responded best to the new regulatory pressure – and who holds the upper hand in F1’s crucial mid-season development race.
