The 2026 Formula 1 season is drawing closer, and teams across the grid are redefining their long-term strategies. Among the most significant potential moves is one that could have far-reaching consequences for the competitive balance of Formula 1: Mercedes is evaluating whether to reduce the number of teams it supplies with its power units. This was confirmed by Toto Wolff, team principal and CEO of the Stuttgart-based manufacturer, who outlined the team’s vision for the next regulatory cycle during an appearance on the Beyond the Grid podcast.
Speaking openly about the future, Wolff explained the reasoning behind a possible change in direction, highlighting how the new era of regulations forces manufacturers to rethink priorities, workloads, and resource allocation.
The strategy behind stepping away from a broad customer base
At present, Mercedes is the engine supplier with the largest customer portfolio in Formula 1. In addition to the works team, Mercedes power units are used by McLaren, Williams, and from 2026 also Alpine. However, Wolff revealed that this structure may not continue beyond the current regulatory cycle.
“We are discussing internally, together with the group’s senior management, the idea of reducing the number of teams we intend to supply in the next cycle,” Wolff explained, adding that the ideal number could be between two and three teams.
This potential decision is driven by several factors, including production timelines, overall workload, and the need to commit to certain technical projects well in advance. From a purely technical perspective, the logic is straightforward: the more teams a manufacturer supplies, the more engines must be produced, assembled, and managed.
Currently, Mercedes AMG High Performance Powertrains can be required to build up to sixteen engines just for the opening round of the championship. While supplying multiple customer teams can provide valuable data to support power unit development, those benefits come at the cost of longer delivery times and increasingly complex production cycles.
Wolff himself acknowledged how challenging it is to strike the right balance between these competing demands, stressing that the primary objective always remains performance for the factory team.
Implications for customers and future competitiveness
A reduction in Mercedes engine customers could significantly alter the dynamics within the paddock. McLaren, Williams, and Alpine are all currently tied to Mercedes through contracts that extend at least until 2030. Even so, Wolff suggested that looking beyond the current regulatory framework will naturally lead to a smaller number of teams being supplied.
This shift would also allow Mercedes to concentrate more resources on developing a power unit capable of returning the works team to consistent title contention. In a highly competitive environment, focusing development efforts more narrowly can be a decisive factor.
There is also a broader interpretation of Wolff’s message in relation to the new technical regulations. As Mercedes prepares for a season that is expected to be highly competitive on the power unit side, limiting external supplies could be seen as a way to protect technological advantages and ensure that development remains closely aligned with the goals of the factory team.
In an era where Mercedes-powered customer teams have often been among the strongest contenders in the championship, such a move would mark a clear shift in philosophy. It could signal the beginning of a new chapter in the relationship between manufacturers and teams at the top level of Formula 1, with greater emphasis on focus, efficiency, and strategic control.
