The lady racer will again be testing with the Williams team into 2015.
Nov.1 (GMM) Susie Wolff will extend her deal with Williams into the 2015 season, according to the German newspaper Bild.
The 31-year-old female Briton was the Grove team's test driver this year, even appearing on a couple of Friday mornings.
"The contract for 2015 is close to being signed," said the newspaper's correspondents Nicola Pohl and Helmut Uhl.
A former DTM and F3 driver, whose maiden name is Stoddart, Wolff's husband is Toto Wolff, the Mercedes team boss and still a significant Williams shareholder.
Bild said her 2015 programme will involve two test days and two further outings during Friday morning practice sessions.
