Ferrari SF-25 unveiled: A Technical Revolution in the Evolution of Formula 1 Cars
Table of Contents
Ferrari’s new Formula 1 car, the SF-25, has made its track debut at Fiorano, Italy, showcasing design features largely consistent wiht earlier renders. though, the team acknowledges the final version, seen in Bahrain during pre-season testing, may differ. The moast striking change is the shift from pushrod to pullrod front suspension,a decision driven by chassis technical director Loic Serra,a recent addition from Mercedes.
Ferrari states that the most visible change
is the switch to pullrod front suspension. This modification, according to the team, is intended to clean up the airflow around the car
, providing greater scope for further aero advancement, which had pretty much been exhausted with the previous iteration.
Wheelbase extension and Aerodynamic Optimization
Ferrari has subtly lengthened the wheelbase by repositioning the front wheels forward. This adjustment creates more space between the front of the sidepod and the wheel, improving control over the front wheel wake and minimizing its negative impact on the underfloor’s leading edge.
Front Suspension Overhaul
the adoption of pullrod front suspension, a departure from the approach taken by customer team Haas, is central to Ferrari’s aerodynamic strategy. As Serra explains, this change is primarily for aerodynamic optimisation and to allow further areas and direction for development.
To further refine airflow, the front trackrod has been integrated, likely within the lower wishbone’s forward leg. Compared to McLaren’s design, Ferrari exhibits a substantially lower level of anti-dive on the front suspension’s rear leg inboard pickup. However,McLaren must still demonstrate that its approach maintains optimal driver feel during braking.
Front wing refinements
While the front wing shows minimal changes from the previous year, the nose’s wide, boxy design at the wing’s attachment point is notable. However, Ferrari’s retention of the slot gap between the nose and the front wing’s foremost element mitigates this issue. This gap allows airflow to pass beneath the nose, maximizing mass flow to the underfloor’s central section.
Sidepod and Radiator Enhancements
The radiator inlet is larger than its 2024 counterpart, a design choice likely influenced by the expectation of a competitive season requiring enhanced cooling capabilities, especially during close racing. The inlet’s integration with the bodywork is improved, minimizing airflow separation. the upper surface covering the inverted L-shaped inlet now features a turning vane at its outer end, generating a vortex that flows over the sidepod’s upper surface. This vortex aims to reduce airflow spillage into the ‘coke bottle’ area at the car’s rear.
The larger radiator inlet necessitates a corresponding increase in the outlet area.To achieve this, Ferrari has incorporated small openings along the engine cover’s spine, similar to those used by Alpine and other teams in 2024. Moreover, Ferrari has extended the gully section on the sidepods’ top surface, creating a raised outer section reminiscent of the 2022 design. This design helps manage airflow over the top surface and improves airflow to the car’s center rear, benefiting both the beam wing and diffuser performance at low ride heights.
Rear Suspension: A Conservative Approach
Ferrari retains the pullrod-operated rear suspension from the previous year. The top wishbone’s forward leg inboard pickup appears relatively low, suggesting increased anti-lift to maintain a lower rear ride height during braking.
Conclusion: Evolution, Not Revolution
While Ferrari describes the SF-25 as an evolution rather than a revolution, subtle changes and unseen modifications are likely present. Pre-season testing will be crucial in determining which team has made the most vital advancements, with the Australian Grand Prix ultimately revealing the true performance hierarchy.
As the team has indicated, this is an evolution as opposed to a revolution – but there are subtle changes and I’m pretty sure a lot more that we can’t see on the renders and pictures so far.
The upcoming season promises intense competition,with the possibility of a team outside the top four in 2024 challenging for top positions.
