Williams' F1 2026 Ambitions: Sainz Urges Fundamental Design Overhaul

Revolutionizing Performance: The Path to 2026 F1 Competitiveness
The Hungarian Grand Prix: A Revealing Test for Williams' Design
Carlos Sainz, reflecting on his initial fourteen races with the Williams team, pointed to the Hungarian Grand Prix as a stark illustration of the team's car design deficiencies. The Spanish driver observed that while the FW47 performs adequately on tracks featuring long straights and sharp turns, it conspicuously struggles with maintaining aerodynamic grip through prolonged, sweeping corners. This characteristic, he noted, has been a recurring theme in Williams' recent car generations, leading to inconsistent results despite some overall improvements.
The Challenge of Current Aerodynamic Characteristics
Despite Williams' efforts to create a more versatile car in the current season, enabling them to score points in numerous races, the inherent design flaws persist. Sainz elaborated that the FW44 through FW46 models, while sometimes fast, exhibited a highly sensitive downforce profile. This "peaky" downforce meant that the cars performed well in specific conditions but faltered when confronted with circuits demanding sustained downforce, such as the Hungaroring, Barcelona, or Qatar. Sainz's feedback following a detailed debrief after qualifying in Hungary underscored these long-standing issues.
Charting a New Course: The 2026 Vision
For the forthcoming 2026 Formula 1 season, which will introduce significant new technical regulations, Sainz believes incremental changes will not suffice. He advocates for a fundamental re-evaluation of Williams' design philosophy. Having transitioned from a leading team like Ferrari, Sainz is uniquely positioned to offer critical insights into what it takes to build a consistently competitive F1 car. He stressed that without a bold shift in their aerodynamic approach, particularly concerning long-radius corners, Williams will continue to face similar struggles.
Aligning for the Future: Team Cohesion and Development
Despite the current limitations, Sainz conveyed a strong sense of unity within the Williams team regarding their future direction. He highlighted the positive collaboration with teammate Alex Albon and team principal James Vowles, indicating a shared understanding of the necessary developmental path. However, a significant hurdle lies in the present: Williams is not actively developing its 2025 car in the wind tunnel, meaning Sainz's detailed feedback on current weaknesses can only influence trackside setup adjustments, not fundamental design improvements for the immediate future.
Focusing on Execution: Maximizing Current Potential
Given the constraints on significant car development for the current season, Sainz intends to concentrate on perfecting race weekend execution. He revealed that he experimented with various car setups during the Hungarian Grand Prix weekend in an attempt to mitigate the car's inherent weaknesses, ultimately reverting to a configuration that had proven effective on other tracks. Recognizing that other midfield teams are advancing their designs, Sainz's strategy for the latter half of the season is to prioritize setup consistency and flawless execution to extract the maximum possible performance from the existing package.
