Williams remains in fifth place in the 2025 Formula 1 Constructors’ Championship standings, but the team based in Grove is feeling increasing pressure from rivals behind them. Stake F1 Team Kick Sauber, Racing Bulls, and Aston Martin are all making strides and aiming to assert themselves in the increasingly competitive midfield battle. To stay ahead of this tight pack, Williams has been forced to react.
In the most recent four Grands Prix, the FW47 has only managed to collect five points—scoring a single point in Canada and four at the British Grand Prix at Silverstone. A string of technical issues and race retirements has slowed the team’s momentum, undermining their earlier progress. James Vowles, Team Principal at Williams Racing, has urged his technical department to take action by revisiting and revising the FW47, with the twin goals of improving power unit reliability and extracting additional aerodynamic performance from the car’s updated floor design.
Although the focus at Grove has already largely shifted toward the development of the 2026 Formula 1 car, the team has nonetheless chosen to introduce a series of upgrades at Spa-Francorchamps. This decision is particularly noteworthy given that the Belgian Grand Prix weekend features a Sprint format, which allows for just a single Free Practice session before parc fermé conditions come into effect. Despite this limitation, the team is pressing forward with meaningful changes.
One of the key modifications involves the radiator inlet on the FW47. The design of the radiator mouth has been changed for two primary reasons: firstly, to enhance the cooling of the Mercedes power unit in order to improve overall reliability; and secondly, to use this as an opportunity to increase aerodynamic efficiency. The redesigned radiator intake now features a lower profile near the chassis and a wider external section. This new shape improves the feeding of the car’s cooling system while also redirecting more airflow toward the rear of the vehicle, enhancing the overall aerodynamic balance.
In addition to the radiator inlets, Williams engineers have also revised the engine cover. The updated design includes tighter and more compact heat extraction outlets, which contribute to reducing drag and improving aerodynamic performance. These changes are expected to bring gains in both cooling efficiency and straight-line speed.
The floor of the FW47 has also undergone notable revisions. The team introduced newly shaped flow diverters at the entrance of the Venturi channels. These updated elements are designed to work more harmoniously with the completely reprofiled outer edge of the floor’s lateral edge wing—or “skirt.” This new floor concept reflects a trend that has become widespread across the 2025 grid: it combines the exhaust outlets with five vortex generators and a longitudinal wing, all integrated into a single aerodynamic structure. This helps generate better airflow management and increased downforce stability.
Furthermore, the aerodynamicists at Grove have also focused their attention on the slot ahead of the rear wheel. This area plays a key role in channeling airflow toward the diffuser, and the revised design aims to improve how efficiently the air is delivered to the diffuser section of the car. By refining the shape and flow direction in this region, the team hopes to achieve a more consistent aerodynamic platform, particularly in high-speed corners.
These updates may not represent a full package overhaul, but they show a clear intent from Williams Racing to defend their place in the midfield battle. With minimal development planned for the remainder of the season, the team is relying on these upgrades to extract better reliability and enhanced aerodynamic efficiency from the FW47—especially critical in a season where every point could make a significant difference in the final Constructors’ Championship standings. All eyes will now be on how well the changes perform at Spa and whether they provide a strong foundation ahead of the upcoming races.
