Williams Unveils Striking 2026 Formula 1 Challenger
Williams has lifted the covers on its 2026 Formula 1 car, the FW48, showcasing a sleek new livery that blends dark blue, black, light blue, and white. The team has also announced a new partnership with Barclays bank as its official banking partner.

The iconic Williams team has taken the wraps off its highly anticipated 2026 Formula 1 challenger, the FW48, revealing a striking new livery that pays homage to the squad's storied past while incorporating a fresh, modern aesthetic.
Adorned in a stunning combination of dark blue and black, the FW48 also features prominent splashes of light blue and white, particularly on the car's sleek sidepods, which will proudly display the logos of the team's new title partner, Barclays bank, as well as long-time sponsor Komatsu.
The new design, which was unveiled in a special ceremony at the team's headquarters in Grove, also sees an increased presence of white on the front and rear wings, lending the car an even more dynamic and aggressive appearance as it prepares to take on the challenges of the 2026 season.
Speaking at the launch event, Williams' team principal, Alex Lowe, expressed his delight at the new partnership with Barclays, stating, "We are thrilled to welcome Barclays on board as our official banking partner. Their commitment to innovation and excellence aligns perfectly with our own values as we strive to return Williams to the front of the Formula 1 grid."
With the new livery and sponsorship deal in place, the team will now turn its full attention to the development of the FW48, as it seeks to build on the progress made in recent years and challenge for podium finishes and, ultimately, a return to the upper echelons of the sport.

Article C3.8.2
Engine Cover
Chapter: C3
In Simple Terms
The engine cover must fit within a defined boundary box and can have up to two distinct sections when viewed from above. From the side, it must completely hide the underlying structure. Additionally, any curved surfaces on the outer parts of the engine cover must have smooth, gradual curves—convex curves need a minimum 75mm radius and concave curves need at least 50mm radius to prevent sharp edges.
- Engine cover bodywork must stay entirely within the RV-EC (Rear View Engine Cover) boundary
- Maximum of two sections allowed in any horizontal plane (Z-plane)
- Must fully obscure RS-EC (Rear Structure Engine Cover) when viewed from the side
- Outer aerodynamic surfaces require minimum 75mm convex radius and 50mm concave radius for safety and performance fairness
Official FIA Text
Engine Cover Bodywork must lie in its entirety within RV-EC, have up to two sections in any Z-Plane, and when viewed from the side, fully obscure RS-EC. Engine Cover Aerodynamic Surfaces in any X-Plane outboard of Y = 5 must contain no convex radius of curvature less than 75mm and no concave radius less than 50mm.
Article C3.8.3
Rear Bodywork Assembly
Chapter: C3
In Simple Terms
The rear bodywork of an F1 car (the sidepods and engine cover) must form one continuous, solid shape with no gaps, overlaps, or disconnected sections. Think of it like clay that's been molded into one unified piece rather than separate parts stuck together.
- The sidepods and engine cover combine to create the rear bodywork assembly
- Must be a single, simply connected volume with no separate or floating sections
- Cannot have overlapping regions - parts cannot occupy the same space
- Once fully defined, the shape must be valid and properly connected
Official FIA Text
Rear Bodywork Assembly results from the Trim and Combination of Sidepod and Engine Cover. Once fully defined, it must be a single, simply connected volume, with no overlapping regions.
Article C3.11.1
Rear Wing Profiles
Chapter: C3
In Simple Terms
The rear wing must fit within a specific design area and can have up to three separate sections. It cannot have inward-curving surfaces visible from underneath, and any inward curves visible from above must have a minimum radius of 100mm to ensure safety and fair aerodynamic performance.
- Rear wing bodywork must stay within the defined RV-RW-PROFILES design box
- Maximum of three non-overlapping sections allowed in the rear wing structure
- No concave (inward-curving) surfaces allowed when viewed from below
- Any concave surfaces visible from above must have at least 100mm radius to prevent sharp curves
Official FIA Text
Rear Wing Profiles Bodywork must lie in its entirety within RV-RW-PROFILES, comprise of up to three non-intersecting simply connected volumes, and contain no concave radius of curvature visible from below and no concave radius less than 100mm visible from above.
