McLaren: 2026 Suspension Choice Driven by Front Wing Aerodynamics

McLaren’s Mark Temple reveals that the industry-wide debate between pushrod and pullrod suspension for the 2026 season is fundamentally an aerodynamic decision dictated by front wing design. While Cadillac and Alpine have broken from the early consensus by adopting pullrod layouts, the majority of the grid has converged on a double-pushrod solution.

Why it matters:

The choice of suspension architecture is pivotal for optimizing airflow and managing the aerodynamic platform under the new regulations. The divergence in design philosophies among top teams suggests that the 2026 ruleset allows for multiple valid performance avenues, making the initial technical choices crucial for gaining a competitive edge.

The details:

• Aerodynamic Primacy: Temple clarified that the decision is not mechanically difficult but is driven by how the suspension layout interacts with the new front wing and front-end aero package.
• Grid Split: Six teams—Audi, Red Bull, Racing Bulls, Haas, Mercedes, and Ferrari—have launched with pushrod suspension at both ends. Alpine and Cadillac are the outliers with pullrod setups.
• Newey's Influence: Aston Martin is yet to decide, with reports indicating Adrian Newey is deliberating heavily. Newey’s past focus on suspension geometry, such as the anti-dive and anti-squat concepts that dominated Red Bull’s recent success, underscores the performance implications of this choice.
• Upcoming Reveals: Three teams remain in the dark. Williams launches the FW48 on February 3, while Aston Martin and McLaren will unveil their cars on February 9, just days before the second pre-season test.

What's next:

The focus shifts to the track as the first pre-season test commences in Barcelona on January 26, running behind closed doors for five days. Following the final launches in February, the teams will converge in Bahrain for the second and third tests, with full live television coverage reserved only for the final session from February 18-20.
