The new technical cycle began to take shape with the presentation of the Haas VF-22, the first single-seater compliant with the new regulations to be presented. The launch event of the Italian-American team did not only serve to show the world the livery, as the car depicted in the published renderings differs from the standard FIA model seen on other occasions, with the same team confirming that it is the real one. and its own Haas 2022 car. However, while sharing a common basis with the car that will take part in the World Championshipthere are several clues that lead to suppose that the presentation in the form of a render has been exploited to alter some technical details, an event that has already occurred in the past with other teams on the grid. In addition to the desire not to reveal their technical choices to the competition in advance, there would in fact have been the need to obscure some solutions of the Ferrari 2022, with which Haas shares part of the mechanics.
The focus is on the front suspension, which in the images published by Haas reproduces the push-rod pattern dominant in the last technical cycle. However, rumors that Ferrari has developed a pull-rod suspension at the front are increasingly chasing. Beyond national borders, the foreign press also expressed their doubts regarding the possibility of a differentiation of choices between the Kannapolis and Maranello teams or whether the front suspension group seen in the Haas images is not entirely faithful to the real VF22. Among the many to report similar considerations are Gary Anderson of the editorial staff of TheRace.com and Tobi Gruner of Auto Motor und Sport from Germany.
The hypotheses gain credibility considering that the 2022 technical regulation requires a lowering of the nose compared to the 2021 single-seaters, facilitating a possible pull-rod architecture that stands out for the downward inclination of the rod going from the wheel unit to the frame. The tie rod scheme guarantees the advantage of housing the internal suspension components in a lowered position in the body, lowering the car’s center of gravity and reducing, albeit marginally, lateral and longitudinal load transfers. This benefits from the grip guaranteed by the tires, as well as the generation of load thanks to the greater stability of the aerodynamic platform. The choice on the most effective architecture between push-rod and pull-rod however it cannot transcend the considerations on the suspension kinematics, on the aerodynamic influence of the external components and on the accessibility to the spring-shock absorber group for set-up operations.
.The next few weeks will therefore provide the answers to two questions. Firstly, whether Ferrari has actually opted for a pull-rod suspension scheme at the front, to which is added the verification of whether Haas has deviated from the technical choice of Maranello at the front by adopting a push-rod suspension, as seen in the renderings , or whether he hid the tie rod architecture during the presentation phase. The first key date is the presentation of the new Red, the F1-75, scheduled for February 17, which will be followed by the Barcelona tests in the following week.
