Mercedes “5 year advantage on everyone” – With the Formula One Sumer shutdown in full swing, the teams are eyeing the return of their engineers and most will be now focused on developing the all new cars for 2026. Aston Martin brought upgrades last time out, which appeared to unlock he potential in the AMR25 as Alonso and Stroll scored good points finishing the Grand Prix in with and seventh respectively.
Williams were the first to dedicate their entire resources at 2026 back in April when the team principal confirmed all his engineers were committed to the project and should he find them working on this season’s challenger, “I would have removed the car from the wind tunnel myself” if needed—their entire focus is firmly on next year’s new rulebook-driven opportunity.”
Kick Sauber too have enjoyed recent success with a suite of upgrades to their c45 beginning in Spain, then phase two came in Austria before their final efforts for the year at the British Grand Prix. With Williams done with their car improvements, this has seen Aston Martin and Sauber close the 31 point gap to Williams, as it stood at the start of the European season, to just eighteen.
Electrical power rise from 1/6th to half
The front runners too will be mostly done with their 2025 cars, although Ferrari yea they will continue to make developments to areas which contribute to mechanical grip, given they can carry this over into the all new designs coming in January. Yet of course its now just the cars which will change dramatically next year, but the power unit manufacturers have been set a significant challenge too.
With the electrical contribution to the Powertrains rising from just 1/6th of the current output to half the total 1000+bhp, Mercedes, Ferrari, Audi, Honda and RBPT have their work cut out. Much of the paddock chit chat prior to the summer break appeared to by consensus agree that Mercedes will waltz back into dominance and this was fuelled by the never ending speculation that Verstappen was leaving for Brackley next season.
Now the 1997 F1 champion, Jacques Villeneuve has poured cold water on suggestions that Mercedes will again crush all before them as they did back in 2014. The Canadian reminds fans and pundits alike that while Mercedes’ engines were the cornerstone of their stranglehold on the sport between 2014 and 2021, the same trick is unlikely to work twice. Eight consecutive Constructors’ titles were won off the back of the hybrid power units first unveiled in Melbourne 2014, a period in which rivals spent more time explaining their deficits to shareholders than closing the gap to Brackley.
Villeneuve is blunt in his assessment. “The rumours are based on what happened at the start of the hybrid era, where Mercedes arrived with a five-year advantage on everyone else,” he tells Vision4Sport. “And whenever someone got close, they could just tune it up a bit. They already had the next version waiting in the garage somewhere until someone caught up.”
Mercedes no “5 year advantage” this time
Unlike the great leap into uncharted hybrid waters more than a decade ago, the 2026 regulations are viewed as an evolution rather than a revolution. The cars will run on sustainable fuels, the electrical element of the hybrid systems will carry greater weight, and the aerodynamic rules are being reshaped to match.
Yet to Villeneuve, this means the element of surprise is gone. “Now everybody’s thinking, they did it once, it will be the same thing now,” he said. “I don’t think the manufacturers will get caught out a second time the same way. Now everybody understands this kind of power unit. They have a good base. So why would Mercedes suddenly be able to take another leap forward?”
Mercedes’ powertrain dominance was once whispered about as though the engineers had found a magic recipe, part science, part sorcery. In reality, they had started earlier, spent more, and played the long game better than their competitors. By the time Ferrari, Renault and Honda had gathered their breath, the Silver Arrows had already spent two seasons fine-tuning their V6 turbo hybrid.
But as Villeneuve points out, the same advantage does not exist today. Each power unit manufacturer is now limited to a particular number of bench test runs they are allowed each two months, the total spend on the research and development for the new engines is now restricted to $90m – Mercedes reportedly blew over $1bn on their 2014 prototype.

2026 F1 powertrains: evolution not revolution
Even Red Bull, who once relied on Renault’s temperamental units, now boast their own engine division in partnership with Ford. Ferrari, despite their flair for drama, have shown recent progress. And Honda, who once fled the sport in embarrassment, are now viewed as a model of hybrid know-how.
The coming power units, mandated to use one hundred percent sustainable fuels, are unlikely to blindside anyone. The electrical boost will account for a larger share of total output, but the systems remain familiar to engineers already well versed in energy recovery, thermal efficiency and packaging. Mercedes may still deliver a competitive package, but the notion of a five-year head start belongs firmly in the history books.
Villeneuve was clear that too many in the paddock are relying on nostalgia. “It’s not a new technology,” he argued. “It’s the same that’s kind of re-imagined, it’s not the same prospect. But they live on that. They might well have an amazing engine, but there’s no way to know now. It’s just rumours. Nobody knows what’s happening in the design department.”
Less naive rivals
In the modern era of F1 where fans are affiliated more with the drivers than the historic nature of the team battles, many of Mercedes followers will have switched their colour to red. Yet those who remain must not expect their team to simply dominate once again given the team are facing rivals who are less naïve, better prepared, and considerably less forgiving.
In truth, Mercedes’ greatest trick may be persuading everyone that history will repeat itself, while quietly wrestling with the same headaches afflicting Ferrari, Honda, and Red Bull Powertrains. Villeneuve’s skepticism may sound harsh, but it cuts through the hopeful noise. Past glories, no matter how bright, do not guarantee future silverware.
Horner out, Cadillac in. Red Bull faces exodus
F1’s gold rush: Cadillac wave fat cheques at Red Bull’s best brains – Christian Horner’s two-decade reign at Red Bull Racing has been reported as officially ended, but documents from UK’s companies house show only the Red Bull boss has been removed as a director. His settlement is likely to be a drawn out affair, with the new Austrian overlords dragging their heels until January, when the Employment tribunal of a female employee dismissed by the team last season is head.
Whilst the deal to pay off Horner is far from complete, what is certain is that Milton Keynes is now under the new stewardship of Laurent Mekies.
Horner’s departure closes a chapter that yielded multiple championships, with a team built on a siege mentality culture of “us against the world,” Horner created a fiercely loyal core of staff. That loyalty to Red Bull Racing, however, may soon be tested. Last month, reports warned of a potential exodus if Horner popped up in another Formula 1 garage. The early rumour mill pointed him towards Cadillac’s all-new project or perhaps a seat at Alpine’s ongoing game of musical chairs… READ MORE
