Williams F1 team is exploring power unit supply options for 2026, according to team principal James Vowles.
The team currently uses Mercedes power units but can switch to another partner after the new regulations come into effect.
As per the 2026 regulations, Mercedes will have to part ways with one of its three customers, thus creating an additional supply from Ferrari.
Renault is also seeking customers, while Honda is an intriguing option after declaring its interest in participating in 2026.
However, Williams will need to demonstrate potential long-term improvement to attract Honda.
"We are at the moment still in the process of making sure we understand all the options available to this team," said Vowles.
"The rules contain some lines which state that theoretically as taken in 2025 this is the number of teams a PU manufacturer can supply.
Same rules, by the way, that should have limited [Mercedes] this year down to less PU supplies than they currently have.
"I think that's an ongoing discussion. But no, we're not locked into Mercedes. And we're still in the process of reviewing.
"But we have to, as all teams will do as well, come to a decision fairly shortly. I think end of the year would be late. So a little bit before then."
