Formula 1 returns after a three-week break, and it does so with the United States Grand Prix. The Texas circuit represents a crucial opportunity for teams that need to determine the technical development of their cars. Many teams are introducing updates, including Haas, which debuts a revolutionary front wing on the VF-24 at the Circuit of the Americas in Austin. Let’s delve into the technical analysis to see how it changes, its potential advantages, and how it may hint at some concepts we’ll see on the Ferrari 677.
The importance of the front wing in this generation of cars is extremely significant. As the first component to interact with the air, it manages and directs the airflow around the car, generating downforce and the necessary turbulence. Mercedes and McLaren have set the standard in 2024 with flexible wings that provide clear advantages at high and low speeds. The latest example was Ferrari, which introduced a radically modified wing in Singapore to improve vortex management.
Haas VF-24 front wing as a testing ground
Following this new philosophy, Haas has chosen its home race to debut this new front wing specification. The changes made to the new spec are diverse and affect various areas of the wing surface. The most noticeable change is in the center, where the nose is now directly connected to the mainplane. Here, the nose cone has been extended and slightly reduced in its section. The aim of this modification is to achieve a clearer separation of the airflow toward the flaps. Speaking of the first wing element at the bottom, Haas engineers have heavily modified the central spoon, lowering the leading edge to clearly split the airflow above and below the wing. This results in greater local downforce (DF), aided by the extended surface of the nose.
Significant changes have been made to the flaps, especially the third and fourth ones, which now adopt a geometry with a reduced chord and a different profiling. We can see that from the nose to the endplate, the flaps do not have a constant chord. This increases downforce in specific areas without further compromising drag.
Despite these significant changes to the flaps and the central area, the most substantial modification involves the junction between the flaps and the endplate. From the mainplane, there is an evident curvature to generate greater local downforce, which is then accentuated by the following flaps with a clear “curl.” These create a powerful vortex channel that directs airflow beyond the front wheel. This is a design we’ve seen on Ferrari and McLaren, with the latter having pioneered this development path in Austria.
A preview of Ferrari’s 2025 front wing?
In recent years, the collaboration between Haas and Ferrari has been extremely fruitful, from testing mechanical components to the power unit. Moreover, the Haas technical department is based in Maranello in a dedicated area, where it shares the wind tunnel with Ferrari.
This collaboration, somewhat speculatively, might even involve minimal data sharing from aerodynamic tests. This is crucial for the 2025 Formula 1 season, where it’s essential to prepare the car properly and not occupy the wind tunnel for 2026. Therefore, it’s reasonable to expect that the tests and data collected during the Texas weekend will significantly aid the development of Ferrari’s next car, especially in a critical area like the front.
