Williams Racing extend Power Unit agreement with Mercedes-Benz

British Formula One team Williams Racing have announced an extension of their Power Unit (PU) agreement with Mercedes-Benz, which will thus continue on as their official Power Unit Supplier as the new regulations roll in come the 2026 F1 season.

The partnership, which started in 2014, is now set to enter another new era, with the 2026 F1 season set to introduce new technical regulation changes.

The power units from 2026 onwards will be using 100% sustainable fuel in adherence to stringent sustainability standards of the FIA to reduce overall fuel consumption. They will also have their electrical systems upgraded to higher performance and feature a single 350kW electric motor, almost three times more powerful than the current MGU-K. The development of the new PUs will also need to adhere to the cost-cap regulations of the FIA.

James Vowles, Team Principal, Williams Racing, commented:

“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.“

Toto Wolff, Head of Mercedes-Benz Motorsport, said:

“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.“
