Wolff to drive one day of pre-season testing
Susie Wolff will drive one day of pre-season testing in the new Williams this year.
In her new role as third driver, Wolff will take part in one day of testing at Barcelona in February before the season kicks off in Australia in March.
Wolff has been promised two first practice sessions at grand prix weekends and two days of testing in 2015. She will also continue to conduct extensive simulator testing at the team's factory.
