WHY MCLAREN SEES MERCEDES CUSTOMER TEAM STATUS AS A DISADVANTAGE IN F1 2026

McLaren boss Andrea Stella states being a Mercedes customer team is now a clear disadvantage, especially looking ahead to the 2026 regulation changes. While not blaming Mercedes HPP directly, Stella points to recent reliability issues – like Lando Norris’s Monaco DNF from a power unit problem – as exposing the structural weakness.

Stella argues customer teams have fewer opportunities to integrate chassis and power unit, leading to slower timelines for addressing reliability and performance issues compared to factory outfits. This hinders combined efforts in facility use and experiments, a crucial aspect in F1's hyper-competitive development race. McLaren’s Zak Brown has even floated the idea of building their own power unit long-term. For now, Stella emphasizes a need to significantly enhance collaboration with Mercedes HPP, with conversations ongoing for months to operate at a "new level" for the upcoming regulatory overhaul. This fundamental shift underscores the challenges of being a customer team in F1’s increasingly complex technical landscape.
