F1 2026 could mirror 2014's engine dominance, warns Newey
Adrian Newey warns that F1's 2026 regulation changes could create engine-dominated competition similar to Mercedes' 2014 supremacy, as manufacturers prepare for unprecedented simultaneous chassis and power unit updates.
Aston Martin's incoming technical chief Adrian Newey has raised concerns that Formula 1's 2026 regulation overhaul could lead to engine supremacy dictating the competitive order, drawing stark parallels with Mercedes' early hybrid-era dominance.
Unprecedented regulatory changes ahead
The 2026 season will usher in one of the most comprehensive technical shake-ups in F1 history, simultaneously revamping both power unit and chassis regulations.
The new power units will abandon the complex MGU-H system while significantly enhancing energy recovery through an upgraded MGU-K, alongside the introduction of sustainable fuels and a novel overtaking assistance system to replace DRS.
Engine advantage could prove decisive
Speaking to Auto Motor und Sport, Newey emphasized the unique challenge posed by concurrent changes to both chassis and engine regulations.
"There has to be a big chance that it's an engine formula at the start.I can't remember another time in Formula 1 when both the chassis regulations and the engine regulations have changed simultaneously."
he explained.
Recovery paths vary by technology
Newey highlighted the different scenarios for performance recovery depending on where manufacturers might find advantages.
He noted that while electrical system deficits could be addressed more readily, combustion engine advantages might prove more permanent due to regulatory constraints.
"If it's on the electrical side, then there's much more ability to catch up if you're behind,"
Newey stated, while cautioning that combustion engine advantages could persist throughout the regulatory cycle.
Expanding manufacturer landscape
The 2026 regulations have attracted significant manufacturer interest, with Audi entering as a new constructor and Red Bull developing its own power units in partnership with Ford.
Honda will continue its F1 involvement as Aston Martin's works partner, while Cadillac's future entry could bring the total number of power unit manufacturers to six.
