Mercedes to power Williams for 2026 regulations

Williams have announced that Mercedes-Benz will remain as their power unit supplier from the 2026 Formula 1 season onwards.

Mercedes started supplying Williams with engines in 2014, when the turbo-hybrid got underway, and the new deal means the partnership will extend into the 2026 technical regulation changes.

F1’s future power units will exclusively use 100% sustainable fuel, reducing overall consumption, while their electrical systems will be upgraded to achieve higher performance.

Williams’ Team Principal, James Vowles spent more than a decade at Mercedes and will have an impressive knowledge of the work Mercedes HPP do at Brixworth to create such a successful power unit.

For Mercedes it makes sense as they have enjoyed a long relationship which helps them to gather data to develop the new generation of power units, also it’s about maintaining the relationship for Mercedes to potentially run one of their juniors with Williams in the future, as they did with George Russell.

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. 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.

James Vowles on the news.

We are delighted to confirm Williams Racing as the second customer team that we will supply for the 2026 power unit regulations. Today’s news highlights the strength of the Mercedes-Benz offering in F1 and importantly not only validates, but reinforces, our overall motorsport strategy. Since 2014, we have continued to build and develop our relationship with Williams. As the team continues to put the foundations in place to challenge at the front of the grid, we look forward to supporting them with our power unit supply
