Most Formula 1 teams have abandoned pull-rod front suspension under the 2026 regulations, reversing one of the defining technical trends of the previous rules cycle. Only Williams, Cadillac and Alpine currently retain the layout, while the rest of the grid has returned to push-rod suspension as flatter floors, reduced downforce and active aerodynamics reshape car design.
The 2026 regulatory overhaul has had a major impact on the single-seaters competing in the Formula 1 World Championship. The return of a floor featuring large flat sections, the move away from an extreme reliance on the Venturi effect, the arrival of power units that depend heavily on electrical energy and the introduction of active aerodynamics have forced teams to reconsider numerous areas of their cars.
Consequently, many solutions that proved successful during the previous regulatory cycle have been questioned by the same teams that originally pioneered them. Front suspension architecture is one of the clearest examples, with the new rules reopening the wider push-rod versus pull-rod debate.
Why pull-rod front suspension dominated before 2026
Between 2022 and 2025, Formula 1 experienced a widespread move towards pull-rod front suspension. Red Bull and McLaren adopted the configuration from the beginning of that regulatory era and, notably, each won two Constructors’ Championships during the four seasons of relatively stable technical rules.
The situation has changed dramatically in 2026. Pull-rod front suspension is now firmly in the minority, with Williams, Cadillac and Alpine the only three teams currently using it.
The cars from the 2022–2026 period needed to run extremely close to the track surface while keeping ride-height variations to a minimum. The enormous amount of downforce generated by the floor also demanded exceptionally stiff mechanical setups, one of the defining consequences of Formula 1’s previous ground-effect philosophy.
The prescribed regulatory volumes required the upper section of the chassis to sit very low. With a push-rod system, this would have forced teams to use a steeply inclined rod. Because a push-rod is primarily subjected to compressive loading, placing it at such an aggressive angle is not mechanically ideal and can introduce unwanted flex.
How Red Bull and McLaren benefited from the pull-rod layout
At the beginning of 2022, Red Bull and McLaren engineers therefore inverted the suspension arrangement. In doing so, they revived a technical solution that had been widely used until the early 1990s, before teams began raising their chassis to improve aerodynamic performance.
Under the previous regulations, pull-rod front suspension offered several advantages. It provided more effective load transmission, lowered the car’s centre of gravity, required a smaller cross-section exposed to the airflow and kept the area immediately ahead of the floor inlet particularly clean.
Those benefits help explain why Ferrari also pursued the concept before the latest rules reset, as explored in a detailed overview of how pull-rod and push-rod suspension affect aerodynamics, packaging and weight distribution.
However, pull-rod suspension always comes with a price. Packaging its internal linkages and steering box is more complicated, while access to the relevant components can also make mechanical work and setup changes less straightforward.
Why the 2026 F1 suspension trend favours push-rod
The return to a so-called flat floor, combined with the freedom to design a substantially higher chassis than in the recent past, has completely reversed the engineering equation. The broader aerodynamic transformation is central to understanding why 2026 F1 cars can use less rigid mechanical setups than their predecessors.
Overall downforce levels have also fallen significantly. That reduction has brought mechanical grip back towards the centre of the performance equation after it was heavily compromised by the exceptionally stiff setups required during the previous rules cycle.
This helps explain the return of push-rod front suspension. The layout was probably also selected because it provides more direct and predictable behaviour while simplifying mechanical adjustments.
That advantage is far from insignificant under the 2026 regulations. Engineers must now manage the considerable variation in front-to-rear axle loads generated by active aerodynamics, meaning a suspension platform that is easier to understand and adjust can offer valuable benefits. Ferrari made the same change with the SF-26, returning to push-rod suspension at the front of its 2026 car.
Why Williams, Cadillac and Alpine retained pull-rod suspension
It is difficult to establish precisely why Alpine, Cadillac and Williams decided to retain the pull-rod solution when most of the grid moved in the opposite direction.
Cadillac entered Formula 1 as an entirely new team. It is reasonable to believe that its front-suspension models may have been developed partly from concepts observed during 2025. For a newcomer building its first car, that approach could be both understandable and rational. Nevertheless, the numerous technical problems Cadillac has encountered specifically in this area suggest that parts of the design will need to be reconsidered.
Alpine may have chosen to limit investment in certain areas and focus more heavily on integrating the Mercedes power unit. For the French manufacturer, that transition represented a significant opportunity to rebuild its competitiveness under the 2026 regulations.
Williams faces questions after its difficult start
Williams’ decision is harder to understand, particularly because such a sharp decline was not expected after its impressive 2025 campaign.
The Grove-based team is attempting a difficult recovery after decades in which it accumulated a substantial technical deficit. As team principal James Vowles has frequently explained, Williams still needs to overhaul its procedures, tools and machinery.
Encountering such an extensive regulatory revolution while undertaking that wider reconstruction may have created a perfect storm for one of Formula 1’s most historic teams. Its decision to retain pull-rod front suspension does not explain every difficulty, but it illustrates how different technical priorities and development limitations can shape a car at the beginning of a completely new rules cycle.
