Carlos Sainz didn’t join Williams to spend a new rules cycle counting tenths to the lower midfield. Yet seven rounds into 2026, that’s exactly where the team finds itself — and the Spaniard’s patience is being tested.
Williams’ start to the season has been messy in the ways that matter most when the regulations reset: the FW48 arrived late and overweight, and the knock-on effect has been immediate. The points return reads like damage limitation rather than a platform for a “relaunch” year — eighth in the constructors’ standings with 11 points, and a best finish of eighth in Monaco.
More telling than the numbers is the tone coming from inside the garage. Sainz, who signed on as part of Williams’ long-term rebuild, has now publicly pushed the team to go further, faster. After a bruising Barcelona weekend he stopped short of making threats, but the message landed like one.
“I know what’s coming, and for sure what’s coming normally in this team upgrades really tend to work,” Sainz said. “But at the same time I’m not sure if it’s enough to cut the gap that we have in this sort of tracks [Barcelona].
“We need to do more than what we are doing already.
“Every week for the team it’s super important to find points of downforce or kilos of weight. I realize that the team is pushing flat out, at the moment we are all pushing with everything we have.”
That’s the crux of it. Sainz isn’t accusing Williams of complacency — if anything, he’s acknowledging the effort — but he’s questioning whether the scale of the response matches the scale of the problem. Under these regulations, you can’t “work hard” your way out of a fundamental deficit. You either move the car’s baseline performance quickly, or you spend a season chasing tracks that flatter you and praying the calendar keeps throwing you a lifeline.
Barcelona didn’t just hurt because of the result. It hurt because it confirmed the diagnosis. Williams expected the Circuit de Barcelona-Catalunya to expose the FW48’s weaknesses — medium- and high-speed performance — and it did exactly that. Sainz finished 12th, two laps down. Alex Albon’s race was derailed by a camera housing issue that effectively turned his afternoon into a rolling test; 11 laps down at the flag, he wasn’t classified.
“The gap to the midfield teams is exactly, more or less, what we thought,” Sainz said. “It’s just that we’ve come to a track where there’s medium and high speed, and we had a big problem in medium and high speed tracks.
“In Suzuka we were really far away from the midfield, half a lap down.”
Williams brought a new rear wing to Spain, including refinements around the Straight Mode fairing aimed at generating more downforce. It was never billed as a game-changer, and Sainz’s readout made it clear it didn’t shift the competitive picture.
“It shows that even if you improve the others are improving also,” he said. “Even if we brought some updates to Miami and Canada, you need to double them up.”
That line — “double them up” — is what will resonate in Grove. It’s not a driver asking for a tweak. It’s a driver asking whether the development rate is aggressive enough to prevent 2026 becoming a write-off before the summer.
Team principal James Vowles has been candid that things haven’t gone to plan, and there’s no sense inside Williams that anyone is trying to spin the situation into something it isn’t. Dorilton Capital’s investment has modernised the operation and the long-term intent is clear, but the short-term reality is stubborn: weight reduction and overall performance are still “in progress”, and there’s no magic fix coming in a single upgrade box.
The tricky part for Williams is that Sainz’s credibility gives these comments weight. He’s been around enough projects to know the difference between a car that’s one good aerodynamic direction away and a car that needs fundamental work, and he’s speaking like someone who’s doing the mental arithmetic for the second half of the season — and beyond.
In the paddock, that naturally feeds the speculation. Multiple sources suggest Sainz is already weighing what his longer-term options look like if Williams can’t pivot quickly, with Audi frequently mentioned as a destination he’s at least keeping an eye on — the move he didn’t take two years ago. The complication, of course, is that Audi already has Nico Hulkenberg and Gabriel Bortoleto under contract for 2027, which makes any near-term switch more theory than plan.
Still, it’s not hard to see why the rumour has legs. A driver of Sainz’s calibre didn’t go to Williams simply to be impressed by effort. He went because he was sold a trajectory — and 2026, by the team’s own framing, was meant to be the first clear sign of it.
What’s making the situation feel more urgent is the calendar’s warning signs. Austria might offer some respite, but Sainz has already mapped out the stretch that could turn “frustrating” into “untenable” if the car’s characteristics don’t improve.
“Bit better,” he said of the Red Bull Ring. “But at the same time, it doesn’t give me much of an encouragement, because if then it means that then you go back to these kind of tracks and you suffer as much, you’re down to the characteristics of the track.
“Then, when we go to Silverstone, it will be even tougher… Then you’re going to go to Silverstone, Spas, and Hungary.”
And he underlined why Barcelona stung in particular: it’s the benchmark track, the one teams quietly use to sanity-check their own claims.
“We need to realise that Barcelona is a very good track to measure a car’s performance,” Sainz said. “We were anything between 1.6 and 1.9 seconds from the leaders and almost six-, seven-tenths from the first midfield cars.
“That’s our target.”
Targets are easy. Closing six or seven tenths to the first true midfield runners — while they keep developing too — is where Sainz’s “do more” becomes less a soundbite and more a deadline. Williams doesn’t just need upgrades that work. It needs a run of upgrades that change what this car is, quickly enough that a driver who still believes in the project doesn’t start planning his exit around it.
