McLaren boss Brown issues verdict on controversial F1 engine change debate

The McLaren CEO, who spoke to GPblog among others, was asked about the much-debated changes the FIA has agreed to implement for the 2027 power unit regulations. The current formula features a 50/50 split between the internal combustion engine and electric battery power, a concept that has continued to divide opinion among several drivers and key figures in Formula 1, including Max Verstappen.

However, offering his view on the proposed changes, Brown reiterated his belief that the regulations still need to evolve. The McLaren boss also suggested there is broad agreement across the sport that further refinement is necessary.

“ We think changes still need to happen to evolve these regulations. I think everybody's in agreement that we can still make changes to make the sport even better. I think, and you guys all know this, people need to park their personal agendas, what they think might make it more competitive or less competitive, and all collaborate,” he explained.

Brown added that there is a general consensus for change, while stressing his optimism that an agreement will ultimately be reached, and warning that it would be a missed opportunity if it is not.

So far, teams remain split over the timing and direction of the proposed power unit changes. While Red Bull Ford, Mercedes and Honda are understood to support an engine revision, GPblog understands that Audi, alongside Ferrari and Cadillac, are currently not in favour of a switch in 2027, citing different concerns.

Earlier, Laurent Mekies backed Verstappen to remain in Formula 1, while also expressing optimism that power unit manufacturers will eventually reach an agreement over the proposed regulation changes coming next season.

The Red Bull Racing team principal, speaking to GPblog and other media outlets, said he remains hopeful that manufacturers will find common ground soon. The 49-year-old suggested that Formula 1 may ultimately require all stakeholders to prioritise the sport’s broader interests over individual competitive advantages.

The Red Bull boss concluded by stressing that the exact split of the engine is less important than delivering a necessary and lasting regulatory fix to the shortcomings of the current rules.

“I don't think the amount of investment is relevant compared to the size of the sport. So I think, let me put it this way, I think we should fix it once and for all and not have this as a recurring topic. I think we have, we see a fantastic battle on the track. There are a lot of positive and a lot of great aspects with what we are seeing, and I think there is a part that we want to improve and we should fight for,” he concluded.
