Susie Wolff has revealed she will drive for Williams during pre-season testing in Barcelona as part of her role as test driver.

When Wolff was promoted from development driver to test driver at the end of the 2014 season, Williams announced that she would get another two FP1 runs as well as two test days in the 2015 car while the team retained its driver line-up of Valtteri Bottas and Felipe Massa.

With pre-season testing set to get underway in Jerez in four weeks, Wolff revealed on Twitter she will be driving in Barcelona - a track she tested on in 2014 - later in February.

The first test at Jerez runs from February 1-4, with the second and third tests in Barcelona from February 19-22 and February 26-March 1 respectively.
