Williams FW48

Late to its first shakedown, the 2026 Williams later gained a B-spec version that is due to carry over into 2027.

About the Williams FW48

Williams switched its full focus to the FW48 on 1 January 2025, earlier than any other team, but production delays meant it missed the private Barcelona shakedown in January 2026. The team answered rumours that it was overweight by publishing a weight of 772.4 kg, and the car first ran at Silverstone on 4 February in a fan-voted one-off livery. Alexander Albon and Carlos Sainz Jr. drive it, and team principal James Vowles confirmed that the B-spec version introduced at the Azerbaijan Grand Prix will be carried into 2027. After the Mexico City Grand Prix, Williams was ninth in the Constructors' Championship with 12 points.

Each model's tier starts from a 0–100 score based on its value plus its power or production numbers. Once enough players have spotted a model, how often it is spotted can move it up or down one tier. How CarSpot rarity works

Rarity is a collectible game mechanic, not an assessment of real-world scarcity or value.
