Susie Wolff's role at Williams could be stepped up for 2014 to include Friday practice sessions.
That is the hope of Wolff's husband, Toto Wolff, who although Mercedes' motor sport boss is also still a minor shareholder of the Williams team.
Susie Wolff, 30, has had a test driver role at Williams this year, and is likely to stay at the British team for 2014.
Asked what his wife will be doing next year, Toto Wolff told Austria's Kleine Zeitung newspaper: "She will probably stay at Williams if she gets a suitable offer.
"But she wants to drive more -- Friday practices or some such," he added.
