On the one hand, Williams’ revisions confirmed some large promise in follow and qualifying – as Alex Albon put the group again in Q3.
As boss James Vowles defined: “We’re in a scenario the place that replace is producing good outcomes, and in a really tight midfield we’re capable of put the automobile again into that Q3 place.
“That was additionally mirrored by a long term on Friday that once more was optimistic. It had pulled away from the midfield, and we have been in a scenario, in actual fact, at occasions, the place our long term was overlaying with Ferrari, which is a really completely different scenario to what we have been at the start the season.”
Nevertheless, every little thing got here crashing down on Saturday night at Zandvoort when Williams found that an error with its personal measurements had meant it had been working with a brand new ground that was exterior the rules.
Whereas the unspecified problem that had made the ground too extensive was a simple repair, and the upgrades ran within the race with just a few refined modifications, having to start out in the back of the sphere with each vehicles (thanks partially to Logan Sargeant’s follow crash) successfully meant the weekend was a write off.
However whereas the missed alternative to attain factors could have been a frustration, the group might be wanting to see whether or not the early promise proven at Zandvoort can observe by means of to the following races.
Right here then is a run by means of of what has modified on the Williams, which is in impact a two-pronged assault of improved aerodynamic surfaces and weight-saving revisions.

Probably the most visible of the Williams alterations comes with a change in method in relation to its sidepod design.
The group is making the change from an underbite-style inlet to an overbite extension panel and beneath slung inlet.
This follows within the footsteps of a lot of its opponents who’ve already made the change, both at first or throughout the season, to assist unleash some aerodynamic freedoms, whereas retaining the required cooling efficiency.
In respect to the latter, the FW46 nonetheless has sizeable inlets beneath the brand new larger prime lip of the sidepod.
The change in bodywork has additionally resulted in a much less aggressive higher gully, while there’s a a lot bigger undercut too.
This feeds rearward and across the sidepod’s flank, the place the raised beltline exposes the narrower underbelly, which has additionally been reprofiled, albeit with an identical however in the end extra aggressive variant of the identical geometries.
Alongside these modifications, the sting of the ground and ground wing have additionally been modified, with probably the most visually obvious alteration being made to the upswept part of the sting wing.
This part is now extra closely cranked, while the separating strakes are way more outlined and deeper than their predecessors.

The group has additionally busied itself with a weight discount programme, with the roll hoop focused as a method to assist it meet its goals.
It’s clear to see that the form of the airbox has been altered, while the spars are additionally configured in another way inside.
Whereas many of those modifications clearly have an aerodynamic impression, it’s the load saving that has additionally been a precedence for Williams in delivering this improve.
As chief technical officer Pat Fry defined: “There’s some tiny element modifications on the aero form across the shrouds and the ducting into the central radiator, however that is all simply chasing the load out the automobile.
“It is a cheap quantity lighter, which is an efficient factor. However we’re nonetheless slightly bit obese. We have just a few extra updates coming later within the 12 months, which is able to hopefully get us proper down on the load restrict.”
