Five updates to the SF-26, three of them on the floor, and by the end of Friday at Zandvoort the two Ferrari drivers may as well have been running different machinery.
Lewis Hamilton was the faster of the pair in the weekend's single practice hour. He ended sprint qualifying seventh, close to six tenths adrift of Charles Leclerc, with no explanation to offer.
"Not a good session, unfortunately, this is the way it is," Hamilton told Crash.net and other reporters at the track. "P1 felt good. We made subtle adjustments to the car, but when we got into qualifying it was a completely different car, so we need to figure out what went wrong and then we'll do our best tomorrow."
Asked what the car needed, he was honest that Ferrari does not yet know. "We'll look at the data and then we'll make a determination. We've just got to go through the data and figure it out. Charles was in a slightly different place to me, a bit closer to where I was, so that's it."
Leclerc, meanwhile, wound up 0.041s from George Russell's pole in a session where less than a tenth covered the top four — and called the lap his strongest of 2026.
"It was my best qualifying lap this year and it means we are doing something right with the feeling," he said. "It doesn't mean it stays forever but it's always good steps in the right direction, especially after such a long break. So a good effort. Unfortunately we just missed pole but we are more or less in the mix."
The timing is what stings. A day before losing the car, Hamilton had been telling PlanetF1.com and other accredited media that Ferrari has finally become the team others copy — the change he says he spent a bruising 2025 demanding.
"Last year one of the things I said was Ferrari should be like the innovators, and everyone should be following it," he said. "And this year we're innovators. You know, people have been following our wing designs, the exhaust system."
He declined to name a single cause. "It's a combination of a lot of things. I think we made a lot of changes to the car, and so it's not just one thing, it's all the pieces of the puzzle. We moved a lot of things around [...] whether it's in engineering, our processes, the design of the car."
And on the timeline: "I think we've got a great collaboration now. It took a good year for us to get in sync, but I think we're there."
The standings support the argument better than Friday did. Hamilton has a win at Barcelona and 169 points, second behind Kimi Antonelli's 219, with Russell nine further back. Ferrari holds second in the constructors' championship, 72 points off Mercedes.
Ferrari's own upgrade paperwork for Zandvoort explains the intent. The reworked floor body, board and edge aim at more aerodynamic load alongside improved robustness of the underlying flow mechanisms, with a reprofiled diffuser and a small beam wing revision to match.
Robustness is the operative word — a floor that holds its behaviour over a broader range of conditions. Hamilton got the opposite. Friday at Zandvoort began damp and finished in sun and gusting wind, and the cars that suffered were the ones whose set-up had shifted in between. Antonelli found the gravel in SQ1 and returned with a damaged Mercedes floor. Hamilton changed less and still lost the car entirely.
Nor was Ferrari the busiest team here. Alpine turned up with eight updates, more than anyone, with Pierre Gasly first in line and Franco Colapinto waiting for Monza. Aston Martin brought five, McLaren three, Mercedes one front-corner change, Red Bull a lone reliability fix on a front wishbone. Williams, Racing Bulls, Haas, Audi and Cadillac brought none.
The sprint grid reads Leclerc third, Hamilton seventh.
