McLaren face a new challenge as the 2026 F1 reset threatens current dominance. The 2026 Formula 1 regulatory reset could put McLaren’s recent dominance at risk.

McLaren and a dominance at risk: the regulatory reset could change everything

The technical revolution planned for Formula 1 in 2026 is not limited to new power units and revised aerodynamic concepts. It represents a true regulatory “reset”, with virtually zero carry-over from previous car designs. For the team that dominated the 2025 season, McLaren F1, this transformation raises fundamental questions not only about how to repeat past success, but also about how to transfer proven technical qualities and established working processes into a radically different regulatory era. The winning approach will be understanding that, even if the technical landscape changes completely, the pillars of success remain the same.

From ground effect to a total reset: what will change

Under the regulations in force until the end of 2025, McLaren proved to be one of the teams best able to interpret the complex ground-effect cars. The Woking-based outfit successfully addressed issues such as porpoising and made effective use of suspension layouts and kinematics that closely resembled some of Red Bull’s well-known technical philosophies. This dominance was the result of a deep understanding of the performance drivers specific to that generation of cars, allowing the team to win championships and build a consistently competitive package.

However, with the radically different technical framework coming in 2026 – where cars will run higher, with significantly reduced Venturi effect and far less sensitivity to ride height – those same suspension concepts and ride-height philosophies will no longer apply. In theory, everything that has worked perfectly up to now will have no direct relevance for the new projects. According to team principal Andrea Stella, though, the key factor is not tied to a specific generation of rules, but to the overall quality of the team and the way it operates. A strong, competent organisation will be able to interpret even the most different set of regulations and still extract performance.

The structural qualities that really matter

McLaren’s technical leadership has been stressing for months that it is not a single regulation set that defines the team’s future, but rather its working culture, the quality of its engineers and the effectiveness of its collective development processes. According to Stella and technical director Neil Houldey, the processes used to take the MCL39 to the top of the grid will form the same type of foundation on which the 2026 cars will be built, even if the technical specifications change dramatically.

“It’s not about abstract targets, but about the methodology we apply every day in the wind tunnel, in CFD and at the factory,” Houldey explained, underlining that the real advantage lies in the ability to push continuously and to maintain the same winning mindset despite an entirely new rule set.

This view is also shared by figures outside McLaren. For example, Toto Wolff has recently pointed out that successful Formula 1 organisations always emerge thanks to the quality of their people and their ability to correctly correlate virtual data with what happens on track, rather than because of individual regulatory details. If McLaren can successfully carry this philosophy into the 2026 project, the team could approach the new season with confidence, despite the complete technical reset imposed by the new regulations.
