The Atlassian Williams FW48 is a Formula One racing car designed and constructed by Atlassian Williams F1 Team to compete in the 2026 Formula One World Championship. The car is currently being driven by Alexander Albon and Carlos Sainz Jr., both in their fifth and second seasons with the team respectively.
Background
Development
Williams prioritised the development of the FW48 before any other team, with development of the FW47 cut early, allowing for full focus on the FW48 from 1 January 2025.[1] However, the FW48's development has been marked by production delays that saw the team miss the private shakedown test in Barcelona in late January 2026. However, the car was still through simulator prep, recording 500 laps with the Mercedes power unit. Rumours circulated that this was because the car was overweight, however, this was not the case as Williams published the technical specifications showing the cars weight to be 772.4kg, just 0.4kg heavier than the W17.[2] The car made its track debut during a shakedown at Silverstone on 4 February 2026, using a special one-off livery voted by fans.[3] The car made its official on-track debut at the first public pre-season test in Bahrain on 11 February 2026.[4]
Livery
The livery was unveiled on 3 February 2026, at Grove. The livery was similar to its predecessor, FW47. However it differs, featuring a gloss blue base. It incorporates a heritage-inspired red and white keyline, a tribute to the championship-winning FW14B and FW18, alongside prominent light blue and white sections on the sidepods and wings to accommodate new partners, including Barclays.[5][6]
