Carlos Sainz has issued Williams with an urgent call to return to the drawing board and bring upgrades as quickly as possible following a damning "realisation" regarding its performance in medium- and high-speed corners.
Williams struggled throughout the Barcelona-Catalunya Grand Prix, with Sainz failing to score a point despite eight drivers encountering problems during the race.
The Spaniard had to settle for 12th at the Circuit de Barcelona-Catalunya, a venue widely regarded as a true litmus test of overall car performance.
At no stage did the Grove-based outfit look capable of challenging for points, with its continued weight disadvantage proving a significant setback.
In addition, according to Sainz, the FW48's general lack of downforce remains an area in need of improvement, with Williams requiring a considerable step forward in performance.
In the 31-year-old's view, Barcelona highlighted just how far behind Williams remains on medium-speed circuits, something the team must address.
"I think, realistically speaking, we expected it to be hard," Sainz told select media, including RacingNews365.
"Looking back on it, I think it's been a bit more of a shock how far off we are in medium and high-speed corners, partly due to weight, but even more importantly, due to the downforce we have on the car.
"So I think it's been massive. I wouldn't call it a shock, not even a wake-up call, because we knew it, but it has been a realisation that we are very far from where we should be, where we targeted to be, or where we want to be.
"So I think it's time to go back to the drawing board and start bringing more things to the car, because clearly, at a medium-speed track, we're very far behind."
