Adrian Newey issues a grave warning to the Formula 1 grid ahead of the upcoming regulations change for the F1 2026 season, with a fearful prediction the sport could return to a Mercedes-like engine-dominated series like it with the turbo-hybrids in 2014.
The Silver Arrows, along with Honda, Red Bull-Ford, Ferrari and Audi will be required to introduce power units consisting of 47% electrical power deployment (350kW) and 53% fuel; which will be ethanol-based and 100% carbon-free, but will still run in a combustion engine.
The Motor Generated Unit-H, which recharges the battery through heat energy, will be abandoned as the MGU-K (Kinetic) is expanded in a bid to combat costs as well as simplifying the complex rules.
It’s a revolutionary and radical change that has the potential to throw the current pecking order of the sport out of the window, particularly when paired with new aero and chassis rules; by introducing lighter cars, moving parts, softer suspensions and the abandonment of DRS.
However, the Aston Martin managing technical partner, who has won 12 constructors’ championships and 223 Grand Prix races, warns it could easily be a double-edged sword for the sport.
“The reality is I can’t remember another time in Formula 1 when both the chassis regulations and the regulations have changed simultaneously,” Newey told AMuS, offering a grave F1 2026 prediction. “And in this case the chassis regulations have been very much written to try to compensate, let’s say, for the power unit regulations.

“So, it’s an extra dimension. I think engine manufacturers will have learnt to an extent on the lack of preparation that the rivals to Mercedes did prior to that change [for 2014].
“But there has to be a chance that one manufacturer will come out well on top and it’ll become a power unit-dominated regulation, at least to start with.
“There’s a chance, if it’s on the combustion engine side of it, that somebody comes up with a dominant combustion engine, that will last through the length of the formula.”
Newey reveals F1 2026 silver bullet
The word on the grapevine is Mercedes are very confident in their upcoming engine and after remaining largely quietly hopeful regarding its prospects, and as time passes the Silver Arrows are becoming more and more publicly bold in their declarations of confidence.
But the one key difference between 2026 and the 2014 seasons will be the electrical demand on the PU is exceptionally higher than it was 11 years ago, offering hope to chasing manufacturers as they look to catch up.
Electrical power offers far more scope for the likes of Audi, Honda and Ferrari to close gaps compared to the mechanical constraints of combustion engines, which could see any potential Mercedes domination cut short far quicker than from 2014-2019.
“Because the way the regulations are written,” Newey continued. “It’s quite difficult for people who are behind to catch up.
“If it’s on the electrical side, then there’s much more ability to catch up if you’re behind.”
