Kimi Antonelli picked Monza for his grid penalty. George Russell isn’t picking anything at all — not yet, and that’s the point.
Speaking to media in Madrid ahead of the Spanish Grand Prix, Russell confirmed he’s holding off on his own power unit change until Mercedes introduces its upgraded engine under the FIA’s Additional Development and Upgrade Opportunities system, expected around the Austin or Mexico City rounds in late October. Taking a grid penalty now, before that new hardware exists, would only set up a second penalty a few races later once the ADUO parts actually go into the car. Russell has dismissed that option outright, saying it would make zero sense to pay the same bill twice.
A Sequencing Problem, Not a Track Problem
That’s a genuinely different approach than the one his teammate took. We wrote last month that Mercedes had all but confirmed a second grid penalty across its two cars without saying where either would land. Antonelli’s answer turned out to be Monza — a short, low-drag lap where a fast car can pass its way through the field in a single afternoon, backed by enough of a championship cushion to spend ten grid spots on purpose. He then turned that penalty into a charge from nineteenth to a home win, stretching his title lead to 66 points.
Russell doesn’t have that cushion, but he also doesn’t need Monza’s forgiving layout, because his penalty isn’t a track problem. It’s a sequencing problem. Formula 1’s power unit rules only start charging five places per element once a driver has already exceeded his season’s allocation, which is exactly where Antonelli now sits. Russell hasn’t crossed that line yet, so for him the far more expensive first offense, a flat minimum of ten places, is still in play. Bundling the parts that put him over his allocation with the ADUO upgrade turns two separate bills into one.
None of this is Mercedes cutting corners. The ADUO framework exists so manufacturers can fix reliability issues without breaching the March 1 homologation freeze that locks in a power unit’s specification for the season, provided the changes don’t add performance. It’s a safety valve for engines built under an entirely new set of 2026 rules and still being learned in real time, which is exactly why more than one team on the grid has needed it this year.
The Cost of Waiting
The cost of Russell’s patience is mileage. He’ll take his current power unit through Baku, Singapore and every round in between on hardware that’s already done months of racing, at the point in the season where reliability margins are thinnest and every rival keeps finding lap time. If that engine fails before Austin, Mercedes loses more than a result. It loses the ability to choose its own weekend for a penalty it already knows is coming.
Russell has also been unusually blunt about where the title fight stands. He conceded in Madrid that his teammate “has done a better job” this year and has earned the position he’s in. Sixty-six points back with roughly a third of the season left is a real deficit, but it isn’t the whole story. Russell still topped opening practice at Madring’s debut weekend on raw pace, proof that the current-specification Mercedes doesn’t need an upgrade to be quick. It only needs to stay ahead of an engine clock that’s now running toward October.
What to Watch Next
Mercedes has offered nothing more specific than Austin or Mexico City, which leaves five rounds, Baku, Singapore, Austin, Mexico City and whatever comes before it, where an aging power unit gets to make the decision for them instead. Ferrari, still sorting out its own internal pecking order, is the team best positioned to capitalize if it does.
