Haas has introduced a major revision to the front end of the VF-26 at the Belgian Grand Prix, as the American team attempts to make its car more manageable for Oliver Bearman and Esteban Ocon. The original solution centres on revised front-wing pylons and a new flow-conditioning element alongside the nose, with Haas aiming to improve airflow control beneath the chassis and address the drivability concerns that followed its previous upgrade package.
The team has also revised the front wing more broadly, particularly around the endplate and footplate. It is an ambitious technical response from Haas, which began the season strongly but has since lost ground as its midfield rivals have raised their performance level through development.
Haas VF-26 front-wing upgrade targets improved drivability
Haas appeared capable of fighting for fifth place in the Constructors’ Championship earlier in the season, with Alpine and Racing Bulls among its main targets. However, that ambition has faded after the VF-26 fell short of expectations. The team is now seventh with 21 points, sitting 39 points behind Alpine and 38 behind Racing Bulls.
At the Canadian Grand Prix, Haas introduced a significant upgrade package under the technical direction of Massimo De Zorzi. While those changes were intended to raise the outright performance of the VF-26, they also made the car more difficult for Oliver Bearman and Esteban Ocon to drive. The results did not match the team’s expectations, prompting a further intervention despite Haas traditionally taking a careful approach to spending under Formula 1’s budget cap.
The latest changes are concentrated at the front of the car, where the revised shape of the front-wing pylons immediately stands out. Haas has moved away from the curved supports that had defined the VF-26 until now and introduced a more unusual solution that could potentially influence future designs elsewhere on the grid.
Two horizontal vanes are now positioned higher and further rearward, separating the new vertical supports. These supports extend much further forwards where they join the main plane and rise above the pylon structure, creating a controlled airflow passage. Haas is clearly seeking greater control over the air directed beneath the chassis, effectively creating a large flow conditioner around the nose area.
The concept has also required a revision to the nose itself, while altering the centre of pressure generated by the front wing. The intention is not simply to add load, but to make the aerodynamic behaviour of the VF-26 more predictable and give the drivers a more usable balance through the cornering phases.
Haas is not the only team refining crucial aerodynamic areas at Spa. Mercedes has also brought a major aerodynamic update for the Belgian Grand Prix, underlining the importance teams are placing on development at this stage of the season.
Revised flap mechanism, endplate and footplate
Haas has also rethought the mechanism controlling the movable flaps. The revised metal system responsible for opening and closing the elements brings a small weight saving, another useful gain in a category where every detail can contribute to performance.
Further changes are visible on the main plane, where a small curl has appeared close to the endplate. The final movable flap has been unloaded in its central section, while the endplate itself has been revised after the diveplane was moved rearwards and lower compared with the specification Haas used at Silverstone.
The new diveplane has a short chord where it attaches to the endplate, then grows considerably towards its outer section and extends slightly forwards. The footplate’s outer edge has also become a much more pronounced curl. At the rear, Haas has retained an outward-angled flow deflector designed to enhance the outwash effect, directing air around the outside of the front tyre.
These details are particularly relevant at Spa-Francorchamps, where teams must balance aerodynamic efficiency with stable cornering behaviour. For a wider look at the technical work seen throughout the paddock, see the latest Belgian GP upgrades from the Spa pit lane.
Haas also changes the VF-26 rear end
At the rear of the VF-26, Haas has introduced a different beam wing intended to make the extraction of airflow from the diffuser more efficient. It is another indication that the package is designed to improve the overall aerodynamic behaviour of the car rather than focusing solely on front-end load.
Oliver Bearman appeared to benefit from the updates during Friday practice, showing encouraging early adaptation to the revised VF-26. Haas will now hope that the new front-wing concept can provide a more forgiving and consistent car for both Oliver Bearman and Esteban Ocon, allowing the team to resume its fight with the midfield rivals that have moved ahead in the Constructors’ Championship.
