Williams will continue to be powered by Mercedes when Formula 1’s new engine regulations are introduced in 2026.
Williams aligned with Mercedes from 2014, when the current 1.6 litre V6 power units were introduced, and on Monday announced a retention of the partnership.
The next cycle of engine regulations, which will feature fully sustainable fuels and a greater output of electric power, will cover 2026-30.
“We have enjoyed a long-term partnership with Mercedes-Benz, and we are thrilled to extend this collaboration into the next era of Formula 1,” said Williams Team Principal James Vowles.
“The expertise, support and technology that Mercedes brings to the table align perfectly with our team’s aspirations in the medium and long term.
“This long-term agreement with Mercedes is a positive step and forms part of our objectives for the future, whilst we will still retain our design and manufacturing expertise and capabilities in-house.”
Williams finished seventh in last year’s Constructors’ Championship during its first season under Vowles’ guidance.
The squad will launch its 2024 season – at which its livery will be presented – in New York on February 5.
Williams has retained Alex Albon and Logan Sargeant as its driver line-up.
Mercedes is set to enter 2026 with McLaren and Williams as its customer teams, with McLaren having previously extended its deal through 2030.
Mercedes’ current other client, Aston Martin, will align with Honda from 2026.
