F1TECH: Haas brings modified rear wing to Silverstone

Having refufused to bring many upgrades across the opening races of the season, Haas has brought a notable aerodynamic update to its rear wing package for this weekend's British Grand Prix, focusing on both increased local load and improved airflow conditioning through refinements to key rear aerodynamic surfaces.

The changes centre on a comprehensively revised rear wing profile alongside a redesigned endplate structure featuring new external protrusions intended to enhance flow behaviour around the rear of the car.

The first element of the upgrade is a new rear wing profile, where the team has reworked the geometry of the wing and its flap configuration. The emphasis has been placed on optimising flap shapes to extract more performance across a wider range of operating conditions.

In practical terms, this means the rear wing is expected to generate more aerodynamic load while maintaining efficiency, rather than simply increasing drag for downforce. In the current power unit era, achieving that balance is critical, as teams constantly try to maximise cornering performance without compromising straight-line speed.

Alongside the profile changes, Haas has also refined the rear wing endplates, introducing localized external protrusions designed to influence airflow structures at the extremities of the wing.

These subtle surface features are intended to promote upwash, helping to better manage the airflow as it detaches from the wing and interacts with the wake behind the car. By improving this flow conditioning effect, the team aims to increase the overall aerodynamic load generated by the rear wing assembly while also improving stability in how the airflow is shed downstream.

Taken together, these upgrades reflect a targeted approach to improving rear-end performance by working on both the core lifting surface and the flow structures that support it. The revised wing profiles provide the primary increase in downforce, while the endplate modifications help ensure that the airflow remains as controlled and efficient as possible as it leaves the car.
