While the majority of the 2026 F1 grid is moving towards pushrod suspension, McLaren is revealing the underlying reasons behind this strategic choice. Behind this seemingly mechanical decision lies a major aerodynamic imperative.
McLaren: Pushrods or tie rods: a purely mechanical, false debate
The 2026 season of Formula 1 marks the emergence of a first clear technical trend: pushrod suspension already dominates the debates. Audi, Red Bull, Racing Bulls, Haas, Mercedes and Ferrari have all converged towards this architecture, both at the front and at the rear. Alpine and Cadillac stand out as an exception with a tie rod suspension, while McLaren, Williams and Aston Martin have not yet revealed their cards.
But for McLaren, The subject goes far beyond a simple mechanical preference. As explained Neil Temple, head of chassis engineering, the key lies elsewhere:
"Ultimately, it all comes down to an aerodynamic choice: what type of suspension works best with your new front wing?"
With the introduction of new aerodynamic regulations in 2026, the front wing becomes the structural element of the entire front architecture of the single-seater. Suspension arms, mounting points, and kinematics are now designed as direct extensions of the aerodynamic flow.
The engineer McLaren insists:"Teams configure their suspension arms according to their front wing package and the entire front end. It's really a question of aerodynamics." »
Contrary to popular belief, the difficulty is not mechanical. Structural aspects of tie rods and pushrods are now perfectly understood. The real challenge lies in managing airflow, rigidity under load, and the stability of the aerodynamic platform.
This debate is a reminder of the historical importance of suspension in modern performance. Adrian Newey had made it a pillar of success Red Bull from 2022 onwards, limiting the effects of porpoising and paving the way for the ultra-dominant seasons of 2023 and 2024.
McLaren As everyone knows, by 2026, the suspension will no longer be an isolated component, but a fully-fledged aerodynamic tool. Woking's final choice, expected at the MCL40 presentation on February 9th, will therefore be a major indicator of its technical philosophy for the new era.
