After a stellar year, McLaren will face a potentially limiting reality ahead of the 2026 F1 season: Oscar Piastri highlights the challenges of being a customer team. The Woking-based team purchases its power units from Mercedes. Brackley’s rivals have had more time to design their cars around the new engine, but according to the Australian driver, this isn’t necessarily a problem.
Making predictions for 2026 remains risky. Certainly, the paddock’s attention seems focused on Mercedes and George Russell, who could be in line for one of the most important opportunities of his career. The Brackley team boasts a power unit that appears highly advanced, which, combined with an aerodynamic platform showing strong potential, could make a decisive difference.
And what about McLaren’s direct competitors? While Ferrari and Red Bull benefit from fully in-house structures, McLaren will again rely on German engines. This dynamic positions the team as a “customer team” and, in theory, could impact their chances of fighting for victories.
Piastri: “Being a customer team isn’t necessarily a disadvantage”
“I think being a works team obviously comes with its advantages, especially now that there’s renewed engine development, but we have a very close relationship with Mercedes HPP, which is extremely positive for us,” explains Oscar Piastri.
“All the initial problems we experienced during testing weren’t due to the fact that we’re not a works team. So I don’t think it’s necessarily a disadvantage. We might be slightly behind them, as they’ve had years to fully integrate these regulations into their car, but we’ve also been working on this process for a long time, so I don’t see it as a definite disadvantage.”
Oscar Piastri’s measured response to the “works team” debate highlights the maturing technical confidence within the McLaren camp as they approach the 2026 reset. By emphasizing the strength of their relationship with Mercedes HPP, the Australian is signaling that the era of customer teams being second-class citizens may be a thing of the past, provided the chassis integration is handled with enough foresight. While the factory Silver Arrows undoubtedly hold a head start in terms of native engine-to-chassis harmony, McLaren’s ability to remain calm through early testing issues suggests they have the internal resources to bridge the gap. The 2026 Formula 1 season will be the ultimate trial of this partnership; it will reveal if a customer can truly outpace its supplier during the most complex regulatory shift in a generation. For Oscar Piastri and the Papaya squad, the mission is clear: prove that brilliance in design is just as vital as the name on the engine cover.
