The 2026 Formula 1 season has started with a technical and political theme that is becoming increasingly prominent and is attracting the attention of engineers, team principals, drivers, and fans alike: the relationship between works teams and their customer squads, particularly when it comes to the supply and management of power units. In particular, the focus of discussion revolves around the behavior of Mercedes in its management of support and technical assistance to the teams powered by the Brackley-based manufacturer, a subject that is sparking considerable debate within the paddock.
In recent days, both Andrea Stella, the team principal director of McLaren, and James Vowles, the team boss of Williams, have hinted at a certain level of dissatisfaction or unease regarding the dynamics of cooperation between the works team and its customer teams. The point under discussion does not primarily concern the raw power or outright performance of the engines themselves. Instead, it relates to the degree of technical support, assistance, and especially the sharing of strategic and operational information that Mercedes is providing, which appears to be less comprehensive than it was in previous seasons. This situation inevitably raises a broader, more philosophical question that has been floating in the background of Formula 1 for some time: how advantageous is it, in the modern era, to fully share your technical knowledge, your proprietary data, and your development insights with customer teams that could potentially become direct competitors on the track?
The first signs of dissatisfaction among Mercedes’ customer teams were already evident during the winter pre-season testing sessions. On that occasion, Flavio Briatore, the former Formula 1 team principal and technical consultant, had suggested that the Brixworth power units supplied to the customer teams were not being utilized at their full maximum potential. According to Flavio Briatore’s observations and his analysis of the telemetry data, the full performance capability of the power units would only be made available from the very first official race of the season. This suggestion immediately sparked discussion among journalists, analysts, and fans about whether Mercedes was deliberately restricting engine performance for strategic reasons, or whether it was simply a matter of cautious calibration early in the year.
The Australian Grand Prix ultimately marked the formal introduction of the full engine mapping for all Mercedes-powered cars, allowing customer teams to finally access the maximum power available from the new hybrid power unit. However, according to reports and insider information emerging in the following days, the most critical aspect of the issue does not concern the overall power output of the engines, which has now reached parity, but rather the software management of the new hybrid units and the strategic control systems that allow for optimal energy deployment, recovery, and efficiency throughout a Grand Prix weekend.
Andrea Stella and James Vowles have made it clear, through various statements and interviews, that certain developments and upgrades related to energy management and advanced software strategies have not been shared with the customer teams to the same depth or level of detail as in past seasons. In practical terms, this meant that during the Melbourne Grand Prix, the gap between the Mercedes works team and its customer teams was more noticeable than usual, creating a tangible difference in race performance and strategy execution. This situation naturally generated some political tension within the paddock, particularly because one of the customer teams, McLaren, is now capable of consistently competing at the very top of the Formula 1 championship, posing a potential threat to the supremacy of the works team if the technical advantage were to be shared too generously.
Ferrari, in contrast, has clearly chosen to take a different, almost diametrically opposite approach in its relationships with customer teams and technical partners. Oliver Bearman, the young British Ferrari academy driver, has explained that the level of technical support provided by Ferrari to its customer teams has been extensive and comprehensive. According to Ollie Bearman, Ferrari has shared a significant amount of detailed information, particularly concerning energy management strategies, data analysis, and race strategy optimization. For example, the American team, powered by Ferrari engines, has received an enormous amount of operational data and technical guidance from Maranello, which has allowed the team to better understand and optimize the performance of the new Ferrari power unit throughout testing sessions, practice, qualifying, and the races themselves.
This open approach has not been limited to Haas. Ferrari has also applied the same philosophy to Cadillac, another technical partner in the 2026 regulations era. By sharing data extensively, Ferrari ensures that customer teams are able to contribute to the broader development effort while also benefiting from the wealth of experience and resources available at Maranello. This strategy appears to be grounded in careful strategic calculation. With a completely new V6 engine and a development phase that is still very much ongoing, Ferrari can gain significant benefits from having multiple teams collecting track data simultaneously, effectively turning its customer teams into additional sensors and testing platforms for research and development. In this way, the data gathered by Haas and Cadillac multiplies the available information for Ferrari engineers, accelerating the refinement of the power unit, improving efficiency, and enabling more precise adjustments across the entire fleet of cars.
Mercedes, on the other hand, seems to be taking a much more cautious and conservative approach in 2026. Having experienced the rapid rise of McLaren in previous years—a team that has, at times, outperformed the works team in the championship standings—Mercedes appears to have decided to protect its technical advantage more carefully. By limiting the dissemination of advanced software solutions, energy management protocols, and certain proprietary upgrades, Mercedes ensures that its competitive edge is retained, even if customer teams benefit from the baseline engine performance. The rationale behind this strategy is to prevent even technically affiliated partners from becoming direct rivals on the track, which could jeopardize the works team’s position in the Constructors’ Championship.
In effect, what we are seeing in 2026 is the coexistence of two nearly opposite philosophies. On one hand, Ferrari leverages its customer teams as development accelerators, sharing comprehensive data, strategic insights, and performance information to expand its analytical base and maximize the rate of progress in engine optimization. On the other hand, Mercedes appears to prefer preserving its know-how and safeguarding its most advanced solutions, opting for a more guarded approach that minimizes the risk of inadvertently strengthening a potential competitor.
So far, both approaches appear to be working effectively. After the opening races of the season, Mercedes and Ferrari have demonstrated the highest level of overall performance, consistency, and reliability. These early results suggest that there is no single formula for achieving a sustainable technical advantage in modern Formula 1. Instead, constructors must find a delicate equilibrium between collaboration and competition, balancing the benefits of data sharing and cooperative development against the risks of empowering potential rivals. Each team must manage these trade-offs according to its strategic priorities, competitive philosophy, and long-term sporting objectives.
The start of the 2026 Formula 1 season therefore illustrates that technical partnerships with customer teams are as much a strategic choice as they are a matter of engineering. Ferrari’s decision to open up its data and involve its partners extensively demonstrates the potential advantages of a collaborative approach, accelerating development and providing richer datasets for analysis. Meanwhile, Mercedes’ more cautious stance highlights the importance of protecting competitive advantage in an increasingly close and technologically sophisticated field, where even small differences in software, energy management, or strategic deployment can have a major impact on race outcomes and championship standings. The contrasting approaches of these two historic teams show that Formula 1 in the modern era is not only a test of engineering excellence and driver skill but also of strategic acumen, political navigation, and the ability to manage complex technical ecosystems across multiple teams and partners.
