McLaren’s turned up at Silverstone with a one-off British Grand Prix livery and, on the face of it, that’s the fun bit. The more revealing detail sits under the engine cover — or, in this case, what *isn’t* there.
Zak Brown has confirmed McLaren isn’t running Mercedes’ latest power unit upgrade this weekend, even though other Mercedes customers have already bolted the new spec into their cars. In an era where gains are fought over in tenths and confidence is as fragile as tyre life on a windy Friday, knowingly leaving performance on the table sounds counter-intuitive. But Brown’s message was blunt: McLaren’s being forced to play the season-long numbers game.
“You’ve got to cycle through your engines, and we’ve got life left on our current engines, so we need to wait till we do an engine change,” Brown said at Silverstone. The regulations guarantee customer teams access to the latest factory spec, but they don’t magic away the limits on how many elements you can use across the year — and those limits drag strategy into the spotlight long before anyone’s thinking about last-lap drama.
Williams, Brown noted, took the updated Mercedes unit because circumstance made the decision for them. “Williams got theirs because Carlos [Sainz] had his issue, so he needed an engine change,” he said. Alpine’s situation was different again, but the point was clear: upgrades don’t just arrive when the parts are ready; they arrive when the inventory allows them to land without turning into penalties later.
McLaren’s position, then, is less about stubbornness and more about not burning through its allocation too early. When you’re already staring down a long season, the risk isn’t just missing out on a modest power increase for one weekend — it’s backing yourself into a corner where the only way out is a grid drop at the worst possible time.
Brown hinted the team expects to be on the new spec from Spa onwards. “You’d want it as quickly as you can, but you need to run the cycles through the engines… we’ll have it soon, hopefully next race,” he said. There was no attempt to pretend it’s ideal. “Any time you have performance that you know is coming, but you don’t have it on your car yet, you want to get it as quickly as possible.”
Still, Brown stopped short of dressing it up as a crisis. “I won’t say it’s a frustration, it’s just what it is,” he insisted — the sort of line you hear from a team that knows how quickly the paddock turns “temporary” into “trend”.
The timing matters because McLaren’s season has already been lumpy. Early retirements and a double DNS in China have left Oscar Piastri and Lando Norris only a point apart in the standings, sitting fourth and fifth respectively, with McLaren third in the Constructors’. It’s not a disastrous place to be, but it’s also not where a team with serious ambitions wants to be midway through a development race that’s already started to bite.
Brown was careful when asked about the broader upgrade battle. Ferrari has been the most assertive early in the year, and Red Bull has been close enough to make every incremental gain feel like a response rather than a plan. “Ferrari and Red Bull have been very, very close,” Brown said. “I think Ferrari and Red Bull have done a fantastic job with their upgrades.”
He also pushed back on the notion McLaren’s standing still. “We’ve done a fantastic job with our upgrades. We’re a little bit behind,” he admitted, before adding the caveat teams always lean on at this point in the calendar: judging the race too early is a fool’s errand because you don’t know what’s still in the pipeline.
The more interesting part was his explanation for why McLaren hasn’t matched Ferrari’s volume of visible changes. It isn’t a lack of parts in development, he insists — it’s about refusing to race items until they’re properly ready to be produced and deployed. “We have just as many upgrades coming, we just haven’t put them on the race car yet, because they’re not quite at the level that we’d like it to be before we reproduce the parts,” Brown said.
It’s classic modern F1: performance isn’t just about having upgrades; it’s about when you can manufacture them, how confident you are that the data will scale from one car to two, and whether introducing them now costs you something later — in parts usage, reliability, or simply distraction.
So the Silverstone story isn’t really the livery, and it isn’t even the missing Mercedes upgrade in isolation. It’s what McLaren’s decision says about the season it’s trying to build: pragmatic, slightly constrained, and based on the belief that the real momentum swing comes when the upgrades land *and* the engine cycle lines up — not when the paddock noise demands it.
For now, they’ll race at home without the latest hardware their rivals have already sampled. And in a championship that’s still young but already unforgiving, McLaren’s betting that patience won’t end up being the most expensive choice it makes all year.
