At first glance, the new FW47 by Williams for F1 2025 season may appear to be an evolution of its predecessor, the FW46, but a closer look reveals significant aerodynamic and mechanical improvements.

 

One of the most noticeable changes is in the sidepods, which now feature a more gradual contour tapering towards the rear. 

 

Additionally, the floor edges have been redesigned with more aggressive vortex generators and an enhanced airflow channel to maximize aerodynamic efficiency.

 

Suspension Overhaul Inspired by Mercedes

Williams has taken a strategic step by adopting a rear pushrod suspension, following the approach used by Mercedes. 

 

This adjustment is expected to optimize airflow toward the diffuser, a necessary change following the decision to implement Mercedes‘ gearbox for the 2025 season, which already incorporates this suspension system. 

 

Meanwhile, the front suspension retains the pushrod configuration, a choice aimed at maintaining a balance between mechanical efficiency and aerodynamic performance.

Ground Effect and High-Speed Stability

The FW47’s floor design remains a fundamental aspect of its performance, as ground effect continues to define the current era of Formula 1. 

 

Williams has focused on increasing downforce in high-speed corners while expanding the car’s handling range, ensuring better drivability without compromising peak aerodynamic efficiency.

 

Adapting to Regulatory Changes

The team had already made strides in developing a front wing with greater aerodynamic flexibility before the FIA’s latest technical directive on this component. 

 

As a result, this front wing will be utilized in the first eight races of the season before the new regulation takes effect. 

 

“We weren’t leading in this area, but the rule change won’t significantly impact us,” said team principal James Vowles.

Williams’ Long-Term Vision

Vowles also highlighted the team’s broader strategy expanding from 700 to over 1,050 staff members and continue to grow. 

 

“We are building a strong foundation for the future, and this year will showcase our progress.”, said.

 

While the FW47 aims to deliver immediate improvements, Williams remains focused on reclaiming its status as a winning team in the coming seasons.

Who will drive the new Williams FW47?

For the 2025 Formula 1 season, Williams Racing’s FW47 will be driven by Carlos Sainz and Alex Albon. 

 

Sainz joins Williams after his tenure with Ferrari, bringing valuable experience to the team. Albon, continuing with Williams, aims to build on the previous season’s progress. 

 

The FW47 was unveiled at Silverstone on February 14, 2025, with both drivers sharing initial testing duties.

 

The official race livery is set to be revealed on February 18 at London’s O2 arena.

 

Sainz has expressed enthusiasm about joining Williams, citing the team’s project and personnel as key factors in his decision.

 

The team is optimistic about the upcoming season, aiming to improve upon their previous performances with the new driver lineup and the FW47.

How did Williams get into F1?

Frank Williams originally ran a team using customer cars.

 

Then in 1977 he set up Williams as an F1 constructor and two years later Clay Regazzoni gave the team its first win at Silverstone.
