The most-shared piece of onboard footage of the early 2026 season has not been from the front of the field. It has been Williams' inside front wheel lifting clean off the road at unlikely places, producing a visual that looks closer to club karting than top-flight Formula 1. The on-grid analysis has been noisy. The Race's diagnosis, however, points at three specific engineering choices, and Williams can change every single one of them.
The Race identifies Williams as having weight, speed and three-wheeling issues with their 2026 car, and lays out the diagnosis in plain terms. The publication points at excessive roll stiffness, aggressive ride height, and simulation-versus-reality differences as the primary candidates. Each of those three is a deliberate set-up philosophy rather than a manufacturing fault, and that is what makes the situation so difficult inside Grove.
The roll stiffness is the most visible cause. When a Formula 1 car is set up too stiff in roll, the inside wheel cannot fully load through quick changes of direction, and in extreme cases the tyre breaks contact with the road over kerbs and crests. The car then becomes nervous in moments where rivals look planted. Williams' choice to run that level of stiffness was a downforce decision; soft suspension hurts the floor performance that defines the new regulations. But on a car that already does not have the floor that Mercedes is enjoying, the trade-off has been brutal.
The aggressive ride height is the second compounding choice. The 2026 floor regulations punish cars that run high, and Williams' design team made the bet that they could push the car closer to the ground to claw downforce back. The penalty for getting that wrong is twofold: porpoising and bottoming on bumps, plus a setup that becomes too sensitive to small changes. Pair that with the stiff roll setup, and the car hops; hop too far and it three-wheels.
The third element, simulation-versus-reality differences, is the one that has caused the most internal damage. Williams' simulator suggested a baseline car that should have been midfield-competitive. Track running has produced something significantly worse. Alexander Albon described setup changes before the sprint that did not help, with the car feeling the same and painful to drive, and admitted the team cannot fix it at the moment. He has spoken about severe vibrations worse than any other session, causing him to lose feeling in his hands and feet, making it impossible to continue much longer. That is not a setup conversation; it is a fundamental modelling problem.
For Carlos Sainz, the experience has been similarly hard to read. He has described start procedure mistakes, hydraulic problems, tyre graining and a list of issues across a single weekend. He has said he could not have built the gap needed to recover from a procedural mistake at the start, and has been frank about feeling let down by a car that the simulator suggested would behave better.
The path forward, as The Race lays it out, is at least clear. Williams can run the suspension softer, lift the ride height, or accept a downforce loss in exchange for stable handling. None of the three causes are unfixable. But the longer the team runs the current package, the more time Mercedes has to consolidate at the front and the more season is wasted answering a question Williams thought it had already answered in the simulator.
