Williams’ Miami weekend looked, on the surface, like the sort of tidy little course correction teams use to convince themselves a messy start to a new rules era isn’t terminal. Two cars in the points, no drama, and a car that finally seemed to be moving in the right direction rather than simply surviving.
Carlos Sainz, though, isn’t dressing it up as a watershed. In his view, what Miami really represented was proof of concept — not proof of arrival. The genuine shift, the one that changes how Williams is spoken about in the paddock, is still weeks away.
“It’s going to take some months to finish the turnaround,” Sainz said after finishing ninth, with Alex Albon 10th to complete a useful double score. “I think we’re going to need to get to the last third of the season to see a proper turnaround.
“But at least the upgrades work. The weight of the car came a bit off, but we still know there’s a bit to go. We have a few bits and pieces coming for the next couple of races.”
That timeline matters, because it frames Williams’ 2026 story less as a sudden breakthrough and more as a grind back to where the team expected to be when it arrived at the first race. The early-season problem was hardly subtle: the FW48 began the year overweight, and the impact was immediate. In a midfield that punishes any inefficiency, Williams’ opening three rounds produced just two points and an uncomfortable sense that the winter had left it chasing its own expectations.
Miami, at least, stopped the bleeding. And it did so with a package that wasn’t merely a token tweak. Team principal James Vowles pointed to a broad sweep of changes: a new floor and bodywork as part of aerodynamic development, front wing revisions, modified rear suspension and exhaust blowing, plus less visible process improvements in how the team extracts and uses performance data at the track.
Vowles described it as roughly 30 “performance projects” pushed through in the five-week gap leading into the event — the sort of language that tells you Williams is trying to fix the machine that builds the lap time, not only the lap time itself.
There was also a small but meaningful step on mass. Williams managed to take “just a little bit of weight out of the car” in Miami, which Vowles admitted “made a difference”. Those are the unglamorous gains teams talk about with a straight face because they know exactly what it’s worth in laptime — and because it’s often the difference between spending Sunday racing and spending Sunday defending.
Still, there’s a caveat Vowles wasn’t shy about: Miami has been kind to Williams before. Albon was fifth here last year and Sainz ninth, and Vowles suspects there are track-specific elements that again flattered the car. He insists those factors are “minor” compared to the wider improvement Williams has made, but the admission is telling. The team is trying to measure itself against the championship’s moving target, not just a circuit that happens to suit.
That’s why both Sainz and Vowles sound careful with their optimism. The upgrades “work”, Sainz says — a crucial sentence, because teams can waste months chasing development that looks good in theory and disappears the moment the wind and track temperatures change. But “work” doesn’t automatically mean “enough”, and Williams’ internal bar clearly isn’t ninth and 10th forever.
The more interesting subtext is the one Vowles keeps returning to: relative development. It’s not simply about what Williams has added; it’s about what everyone else is about to add, and when.
He noted that rivals in the same slice of the midfield picture — naming Audi and Haas in particular — didn’t bring performance to Miami, warning that the landscape could shift quickly over the next few races. Williams can plan its own upgrade cadence, but it can’t predict when a competitor lands a genuine step or when someone arrives with a bolt-on solution to a fundamental issue.
“What we can control is what we have available to us,” Vowles said, “and that is what we can bring in terms of performance and updates over the next two rounds to ensure that we’re just stepping forward relative to the field in small steps every time.”
That “small steps” mantra is doing a lot of work. It’s both realistic and slightly sobering, because it acknowledges what Williams isn’t right now: a team with the sort of headroom that allows it to leapfrog the midfield in one hit. Vowles even pointed to the benchmark Williams is eyeing, saying Alpine currently holds “fifth-fastest team” status and that Williams still has “a few tenths” to find.
Canada, he hinted, could bring another push — though he also admitted the exact delivery is “still up in the air” and dependent on what the team can “100 percent deliver” in time. That’s a familiar modern F1 tension: the upgrade plan looks clean on a chart back at the factory, then reality arrives with production lead times, correlation questions and the sheer brutality of a calendar that doesn’t pause for anyone.
Vowles’ longer-range confidence is more concrete. He says Williams has a programme — weight reduction, aero development and vehicle dynamics work — mapped “all the way to and just slightly beyond the August break”. By then, he expects Williams to be in a “comfortable position” where it’s “consistently scoring points every weekend”.
Sainz’s “last third of the season” line fits that same arc. It’s not a plea for patience so much as an attempt to set the expectation correctly: Williams isn’t waiting for a miracle part; it’s trying to execute a sequence. Miami was one piece landing where it should. The next question is whether the rest of them arrive on time — and whether the midfield stands still long enough for anyone to notice.
