Haas sticks with push-rod setup: no pull-rod front suspension like Ferrari. Haas will not fully adopt Ferrari's technical directions with 2025 F1 car.

Haas will not fully adopt Ferrari’s technical directions. The American team’s tenth F1 car will obviously retain a “family feeling” with Project 677, the Ferrari being developed in Maranello for Lewis Hamilton and Charles Leclerc, but it will not adopt all of its concepts.

According to information gathered by Motorsport.com, the VF-25 will not feature the pull-rod suspension setup at the front, which the Maranello team has opted for. Andrea de Zordo, Haas’ technical director for a year and with the team for four years, has logically decided not to follow Ferrari’s front-end design, instead choosing to remain faithful to the push-rod suspension used successfully this year.

In the final year of regulations for ground-effect F1 cars, Haas did not feel it worthwhile to invest in a suspension setup that might not evolve with the introduction of agile cars under the new 2026 regulations.

As an American-licensed team, Haas must optimize its resources and has already shifted its focus to the car that will, in the coming months, require significant human and financial resources. Hence, Haas has chosen not to push the current project to extremes, instead seeking continuity with the VF-24 wherever possible to save investments for the completely new 2026 project.

Those who think the 2025 Haas might be a “carry-over” car—an evolution of last year’s model—are mistaken, as the 2025 USA car will be significantly different. It will follow Maranello’s guidelines, where certain elements have been repositioned to achieve the weight distribution mandated by FIA regulations.

The chassis will therefore be new, with a carbon insert extending the section ahead of the cockpit, increasing the distance between the front wheels and the start of the sidepods. This will improve the management of losses, ensuring that turbulence does not disrupt airflow to the floor and rear.

To comply with the 3,600 mm wheelbase regulation (with the maximum allowed wheelbase utilized by all teams), it will be necessary to shorten the gearbox housing, which will also incorporate a new rear suspension.

It should be noted that Haas has a design center in Maranello, housed in the same facility as Ferrari’s simulator. The construction of structural parts is entrusted to Dallara, while other components are partly outsourced to Toyota, a new partner, and partly to a British supplier, as the racing team is based in Banbury. Haas is a unique team with a “tentacular” organization, headquartered in Kannapolis, North Carolina, in the United States.
