Zak Brown has hinted that McLaren could consider a significant change to its engine supply arrangements — but only if a specific condition is met. The McLaren CEO’s comments have sparked fresh speculation about the team’s long-term power unit strategy at a critical moment in Formula 1’s technical history.
The condition that matters
The 2026 season marks the arrival of Formula 1’s most sweeping power unit regulations in over a decade. The new hybrid architecture — which requires roughly equal contributions from the internal combustion engine and the electrical deployment system — has reshuffled the competitive order and put a premium on having the right engine partner. For McLaren, that currently means Mercedes, a relationship that has been in place since 2021 after the team ended its troubled partnership with Honda.
Brown’s suggestion that a change could come under the right circumstances raises immediate questions about what that condition might be. Without confirmed details from the source, the nature of the caveat is not yet public — but the very fact that McLaren’s CEO is speaking openly about the possibility signals that this is not idle speculation. Brown is not a figure who floats major strategic ideas carelessly.
McLaren’s current Mercedes supply has served the team well. Lando Norris and Oscar Piastri are operating at the front of the 2026 grid, and the team arrives at each race weekend as genuine contenders. Disrupting that arrangement would require a compelling reason.
What a change could look like
The most discussed alternative in paddock conversations has long been the possibility of McLaren eventually running its own works-style power unit, though the investment and lead time required make that a distant prospect at best. More immediately realistic would be a switch to a different supplier — Ferrari or, notably, the newly restructured Honda programme, given the history between the two parties.
Honda returned to Formula 1 in 2026 as a full works partner with Aston Martin after years of supplying Red Bull under a rebadged arrangement. Whether their current commitments leave room for a secondary supply deal is a separate question, but Brown’s comments will inevitably prompt renewed interest in that direction.
There is also the matter of timing. Engine supply agreements in Formula 1 are multi-year deals negotiated well in advance. Any change Brown is hinting at would realistically affect 2028 at the earliest, which means the conversations — if they are happening — are already underway behind closed doors.
For now, McLaren’s focus is firmly on the 2026 championship fight, with Norris and Piastri pushing hard at each round. The next opportunity to press for more clarity from Brown is likely to come at the Canadian Grand Prix in Montreal, where team principals and senior figures are traditionally more accessible ahead of the race weekend.
