In recent months, there has been growing discussion about the possible superiority of the Mercedes power unit compared to Ferrari and the rest of the competition, with James Vowles offering some specific comments regarding the Scuderia.
Over the last period, countless rumours have emerged ahead of the next season, which will usher in the biggest regulatory change in Formula 1 history and has forced all teams to effectively start from scratch. Many observers have pointed to a potential advantage for the Mercedes power unit over the rest of the field, even if the Williams team principal, James Vowles, was keen to highlight a particular detail concerning Ferrari.
The past few days have been genuinely turbulent following the latest development to surface. It has been widely rumoured that, by exploiting a grey area in the 2026 regulations, Mercedes could secure around 15 extra horsepower compared to its rivals. Such an advantage would reportedly be worth around three tenths of a second per lap, placing the other engine manufacturers in a critical position. For this reason, discussions with the FIA are said to be ongoing, although the situation is clearly still evolving.
James Vowles believes in Ferrari?
In recent weeks, the Williams team principal was asked whether the Mercedes engine should be considered the favourite compared to the others in 2026. Here is the response from the former Mercedes strategist. “No engine manufacturer knows where they will be next year. I believe that some of the rumours have come from one specific team and one specific engine manufacturer, in order to shake things up. Nobody really knows how things stand. I strongly doubt that Ferrari has done a poor job, and the same applies to Honda. I don’t think this is a situation similar to 2014. We have been working with Mercedes since the start of 2024, when we signed the supply agreement. What I can say is that they have prepared well.”
James Vowles’ comments clearly refer to the alleged superiority of the Mercedes power unit compared to Ferrari and the other engine manufacturers. His statement came before the so-called ‘power unit gate’ issue emerged, although the British team principal’s answer would likely not differ from what he has already said. The message is that the rumours may not be entirely accurate and that, until the Australian Grand Prix, very little will truly be known.
The aim, therefore, appears to be to ease the pressure. The Williams boss knows the potential of the Mercedes power unit very well, given that Brackley is Williams’ engine supplier. His final remark, “What I can say is that they have prepared well,” offers a clear indication of that belief. For now, all that remains is to wait for the verdict of the track.
While the paddock whispers of a return to Mercedes dominance, James Vowles’ diplomatic defense of Ferrari and Honda reminds us that the 2026 engine war is far from settled. Whether his comments are a genuine assessment or a tactical move to lower expectations for the Brixworth-powered teams, the true hierarchy will only be revealed when the lights go out in Melbourne. Until then, the tension between rumored gains and technical reality continues to define the road to the new era.
