Williams’ 2026 Formula 1 campaign is telling a different story from what the results alone might suggest. The FW48 was not born under ideal circumstances, forcing the Grove-based team onto the back foot from the very beginning after missing several key development targets during the design phase.
According to information gathered, the car started the season carrying around 30 kilograms more than its intended target weight. In modern Formula 1, that represents a huge handicap, as every kilogram can be worth several hundredths of a second per lap while also affecting tyre management and the car’s overall aerodynamic efficiency.
Within that context, the Mercedes power unit has undoubtedly been a valuable asset, but its influence can only go so far. Even the strongest engine on the grid can only partially compensate for a car that is fundamentally overweight and less efficient than intended. As a result, those at Grove have never underestimated the scale of the challenge involved in closing the gap to Formula 1’s leading teams.
Encouraging signs in Barcelona as major post-summer upgrade takes shape
Even so, progress is beginning to emerge. The Spanish Grand Prix proved to be one of Williams’ most encouraging weekends of the season. The FW48 demonstrated clear improvements, with its performance deficit shrinking compared to the opening races despite the car still being significantly above the minimum weight limit. Around 17 kilograms remained to be removed.
Speaking at the Red Bull Ring, Alex Albon explained:
“Barcelona was a good test for us because it’s always been one of the circuits where we’ve struggled the most. I think it was a bit of a reminder of how far behind we still are in certain areas. There were a couple of corners that really stood out, where we were losing four tenths in a single corner.”
The Thai driver then expanded on the FW48’s long-standing weaknesses, particularly the team’s difficulty in finding the right setup:
“The preparation for this year’s upgrades, but also for next year’s car, is focused on understanding where these weaknesses come from. Last year we were generally a little closer to the top teams in terms of cornering speed. This year, especially through medium- and high-speed corners, we’ve actually taken a step backwards.”
Albon also addressed the ongoing weight reduction programme, expressing confidence that Williams can continue introducing effective upgrades in the same way as Formula 1’s leading teams:
“I think as a team we’re more than capable of doing that. We’ve got a really strong group behind us. We’ve already taken a good amount of weight off the car since the opening race, and there’s more to come later this year. I’m confident that by the end of the season we’ll have the weight where it needs to be.”
That optimism highlights the considerable room for improvement still available. Every kilogram removed not only improves outright lap time but also gives engineers far greater flexibility when it comes to ballast placement, weight distribution and overall vehicle balance.
The biggest step forward, however, is expected during the second half of the season. Williams is preparing an extremely ambitious development package that is currently scheduled to debut by the end of September, around the Azerbaijan Grand Prix.
According to paddock sources, the update will involve such an extensive redesign that some insiders have described it as affecting “half the car.” The objective extends well beyond further weight reduction, with engineers also aiming to address several aerodynamic and mechanical compromises that have limited the FW48’s potential during the opening phase of the championship.
For Team Principal James Vowles and his technical staff, this represents a crucial milestone in the long-term rebuilding project. Williams has invested heavily in new infrastructure, personnel and development tools, but turning years of technological deficit into on-track performance inevitably takes time.
Carlos Sainz balancing short-term improvements with Williams’ long-term future
One of the people following this progress most closely is Carlos Sainz. The Spaniard joined Williams with a long-term vision in mind and hopes these upgrades will allow the team to arrive at the new Madrid Grand Prix with a far more competitive package than the one seen during the first half of the season.
In Austria, Carlos Sainz reaffirmed his commitment to the project while highlighting the importance of the work taking place behind the scenes at Grove:
“The team knows what my intentions and priorities are, which is to continue with this team and this project. I believe in the long-term side of the project and in the long-term vision. Right now, as I’ve said before, we’ve got a lot of work to do on the present.”
Expanding on that point, the former Ferrari driver added:
“I spend a lot of time at the factory, and I’m doing both things. You focus on the short-term improvements and spend time on the immediate priorities, but I’m also spending a lot of time working on the medium- and long-term projects. We’re already running simulator sessions with the FW50, which is next year’s car, changing every parameter we can to understand what will deliver the biggest performance gains.”
Carlos Sainz also discussed the impact of Williams’ new simulator, which is now fully integrated into the team’s development programme:
“It’s now fully operational, running five days a week with all our development drivers, our support team, and both Alex and myself. It’s a tool, and I’ve always said it’s more valuable for the engineers than for the drivers. It’s there to guide the engineers in the right direction. I’m happy to drive it and help develop the car around it because I believe it’s an extremely important tool for the team’s long-term development.”
Williams’ home Grand Prix will provide an important showcase not only for Carlos Sainz but for the entire rebuilding project at Grove. If the extensive upgrade package expected around the Azerbaijan Grand Prix delivers on its promise, the historic British team could finally begin seeing tangible results from a recovery plan that, despite setbacks and delays, continues to move steadily in the intended direction.
