Williams have categorically rejected reports that they might become the new works Honda team for 2018.
It is believed that McLaren will split with the struggling Japanese manufacturer after three hapless years, potentially leaving backmarker Sauber as the only Honda-powered team next season.
Williams, however, has been linked with taking over the McLaren deal, but deputy chief Claire Williams told Blick: "The rumours about talks with Honda are just wrong.
"We are more than satisfied with our Mercedes power. So there is no question of a change."
Williams are sixth in the constructor standings ahead of Sunday's Azerbaijan Grand Prix.
