Why Williams' FW48 upgrade in Baku is so crucial

Baku is a defining weekend for Williams. After a season of delays, weight issues, and poor results, the team finally brings the major FW48 upgrade. Sainz and Albon have five points finishes, none since Monaco, as the midfield has moved on.

Why it matters:

This is more than a 2026 boost. It's a test of Williams' new processes and James Vowles' leadership. A solid step would validate the direction and boost confidence in the FW50.

The details:

• The FW48 missed a Barcelona shakedown and arrived overweight.
• Small updates, like a new front wing, haven't stopped Williams slipping to P15-P17.
• Albon: "Even midfield teams are bringing three or four upgrades a year... We've fallen back."
• The Baku package was signed off months ago when gains looked competitive, but rivals have improved, so the jump is smaller.

Between the lines:

This is likely Williams' last major 2026 upgrade. Sainz says it will help motivation, maybe a point or two, but "it's nowhere near where we want to be." Both drivers are already looking ahead.

What's next:

Vowles admits Williams lacked simulation tech last winter, developing in the wrong direction. He's overhauled processes and hired key people like Piers Thynne. If Baku delivers, it proves Grove is on the right track—even if the FW50 isn't guaranteed.
