A challenging but productive Bahrain test
The assessment of Williams after two weeks of winter testing in Bahrain can be described as mixed. If the morning sets the tone for the day, the Grove-based team experienced a tough start but maintained a highly productive schedule. Following a significant initial setback – the team’s forced absence from the Barcelona shakedown due to delays in passing the mandatory crash tests – Williams, under the leadership of Team Principal James Vowles, responded by logging extensive mileage at the Sakhir circuit. The FW48 accumulated laps with impressive consistency, attempting to recover lost ground that, at the start of such a major technical revolution, can feel particularly burdensome.
Testing numbers reveal consistency
The statistics paint a picture of a team working tirelessly. Carlos Sainz proved once again to be a methodical and precise driver, completing a total of 410 laps during the preparation in the Persian Gulf. In the desert mileage ranking, the Spanish driver ranked fourth overall, surpassed only by Oscar Piastri with 437 laps, George Russell with 434, and Charles Leclerc with 421 laps. This result demonstrates the reliability provided by the new Mercedes Power Unit, effectively acting as an insurance policy that allowed the Grove engineers to focus exclusively on understanding a car that arrived late and is still far from its final form. However, beneath this mechanical solidity, the first cracks in pure performance started to appear. In long-run simulations, the FW48 seemed less competitive compared to the mid-field teams that impressed the most during testing, particularly Alpine, Haas, and the surprising Audi.
Sainz sets realistic expectations
Carlos Sainz was candid during the drivers’ press conference, acknowledging that while optimism had reigned in the team until last year, the winter testing period brought a harsh lesson. Williams, alongside other teams outside the top four, is still far from the level required to navigate such a radical regulatory change effectively. The performance gap to the front is not solely due to the chronic overweight issue that has historically affected the FW48, but also due to a genuine lack of aerodynamic downforce. Sainz emphasized that Williams was less prepared than the championship giants, stating that the advantage of the cars ahead is not just a matter of weight, but also a real deficit in performance.
At the end of the final collective testing day, Sainz confirmed that Williams is entering the season with lower expectations compared to 2025. He explained that the six days of testing in Bahrain were among the most challenging and interesting of his career due to the new regulations and the sheer volume of information the team needed to process. He acknowledged significant progress from the first day, but emphasized that many aspects still need to be understood and resolved before the start of the season. Sainz noted that the FW48 arrived late and its aerodynamic package is not yet fully updated, meaning the team faces a long road ahead to improve competitiveness. He stated that the focus remains on understanding how to get the most out of the car and on gradually solving the remaining issues to be better prepared for Melbourne.
Albon highlights consistency and preparation
Meanwhile, Alex Albon emphasized the regularity of the testing program in Bahrain, describing it as a relatively smooth and productive session. He pointed out that the team completed a solid amount of mileage and tested all the aspects they wanted to explore with the FW48, which made him feel more prepared for Melbourne. Albon acknowledged that there is still much to understand and significant performance left untapped, but he expressed satisfaction that testing went according to plan. He also highlighted the importance of data analysis in the coming days to extract the extra performance that was missing at Sakhir.
Vowles outlines aggressive development plans
James Vowles provided an overview of the entire operation, praising the team’s reaction to the challenges faced. He explained that, over the six days of testing, the team was limited mostly by time and available tires rather than reliability issues, a testament to the hard work carried out at both the track and at Grove. When discussing performance hierarchies, Vowles remained cautious but admitted that Williams needs to recover from the missteps of this winter. He stressed that nobody truly knows the absolute performance levels yet, and Melbourne will provide a clearer picture of the team’s position. Vowles reassured that an aggressive development program is in place to extract every possible ounce of performance from the FW48 over the coming months, acknowledging that the team has put itself at a disadvantage but is committed to closing the gap as quickly as possible.
