McLaren remains dedicated to Mercedes despite concerns from customers.

      McLaren CEO Zak Brown has sought to clarify the team’s stance amid increasing talks about the challenges faced by customer teams in the new engine era of Formula 1. Team principal Andrea Stella has reiterated during the Monaco weekend that customer teams experience limitations compared to manufacturers in integrating and developing the new 2026 power units. McLaren's ongoing reliability issues this season have heightened the focus on this matter. World champion Lando Norris has encountered a series of technical difficulties, while there is ongoing speculation that some of the team’s challenges may be connected to the Mercedes-supplied power unit used by the leading factory team. However, Brown emphasizes that McLaren is fully dedicated to Mercedes. "I want to first emphasize that I am very pleased with Mercedes HPP (High Performance Powertrains)," he stated. "There has been a common belief that a customer engine cannot win a world championship. We have shown that it is achievable." McLaren secured both titles in 2025 despite being a customer team and is contracted with Mercedes until the end of 2030. "Our primary focus is to remain with Mercedes until the new regulations come into effect, as they have been an excellent partner," Brown mentioned. He noted that circumstances have improved significantly since the beginning of the season and expressed optimism that the team will continue to strengthen in the near future. Brown did acknowledge that McLaren may consider developing its own engine if Formula 1 transitions to a simpler power unit formula down the line. "Each time new regulations are introduced, we will examine them to determine if they are technically appealing and if it makes financial sense," he explained. "If that time arrives, we will evaluate that possibility, but currently, we are very satisfied with Mercedes and expect to continue with them." Brown shared his approval of the direction in which Formula 1 seems to be moving. "A V8, a larger combustion engine, sustainable fuels, reduced dependence on battery power, and enhanced sound – it all sounds positive," he remarked. "It appears to be a promising path for the sport." The American also called on manufacturers to support initiatives aimed at improving the contentious new engine regulations. "We believe that modifications are still necessary to enhance these regulations," Brown stated. "Everyone needs to put aside their personal interests for a bit and refrain from thinking about what makes them more or less competitive, focusing instead on collaboration. I think there is a broad agreement that changes are essential. It would be regrettable to miss the opportunity to improve our sport."
