The Japanese manufacturer officially withdrew from F1 at the end of last year, but recently revealed that it had registered with the FIA to be able to produce a power unit for the 2026 regulations.

While neither Reuss nor Andretti offered any details of which manufacturer it was planning to work with, the most logical one would be Honda. Michael Andretti added: 'It'll be more of a collaboration I think with another manufacturer.' 'And then, as we move forward, we bring a lot of our expertise to create things for the future as well.' 'We have a signed agreement with a power unit supplier to begin with,' he said. However, GM president Mark Reuss has clarified that an agreement has already been reached with a current F1 engine manufacturer to use its power unit initially. The involvement of GM in the project has caused a surprise because it is not thought the American manufacturer had any intention of building its own F1 power unit from 2026, with the registration deadline having now passed.
