Williams test driver Susie Wolff will get behind the wheel of the team's 2015 car on the first day of the second pre-season test this week.

The 32-year-old is expected to drive the car regularly this year, after she earned a promotion from her role of development driver last season.

Wolff will drive the car on Thursday in Barcelona, before race drivers Felipe Massa and Valtteri Bottas share the running for the following three days.

There are eight days left of pre-season, before the 2015 campaign starts in Melbourne, Australia in a month.
