Mercedes has shut the development tap on its W16. Toto Wolff says there are no more upgrade packages coming in 2025, with the team now all-in on the seismic rules reset arriving in 2026.
The message landed during the Hungary weekend, where Wolff told media including PlanetF1.com the focus has flipped: “No, there’s no more upgrades. I think everything is completely focused and concentrated on next year.” He added that Mercedes will spend the remainder of the campaign squeezing what it can from a “more stable platform,” leaning on setup work and track-by-track optimisation rather than chasing new aero bits.
It’s the pragmatic call almost every team is making. With both the chassis and power unit regs being torn up for 2026, the late-season Friday declarations are already thinning out. Team representative Bradley Lord flagged as much recently, noting we should expect little more than circuit-specific wings in the second half of the year. The upgrade bulletins will look sparse; the wind tunnels and dynos won’t be.
Behind the factory doors, Mercedes High Performance Powertrains is deep into its 2026 unit, designed around a far larger electrical contribution alongside the internal combustion engine. That balance is at the heart of the new formula, and Mercedes is intent on delivering a package that works for itself and its customers on day one.
None of that means the lights are off on the 2025 car. Expect the team to hunt marginal gains with setup, correlation, and execution — the sort of groundwork that can still swing Sundays even without new carbon on the car. In a tight midfield-to-front spread, it matters.
As for the scoreboard, Mercedes heads into the run-in third in the Constructors’ standings, 24 points behind Ferrari. That gap frames the risk-reward of this strategic pivot. There’s no magic package left in the pipeline to transform the pecking order; the task is to defend and pounce with what’s already in the garage.
It’s a familiar late-cycle gamble, and Mercedes has played it before. In an era-defining reset, the teams that commit early and learn fast tend to land on their feet. For Wolff’s squad, the rest of 2025 becomes a rolling test session — valuable mileage, sharper operations, and, if they execute, a few more podiums to keep the scoreboard honest while 2026 takes shape.
