Susie Wolff (picture) will take part in two grand prix practice sessions next season in a new role of official test driver for Williams, the F1 team said yesterday.

Wolff, the British wife of Mercedes motorsport head Toto Wolff, has been development driver for the team for the past three seasons.

The team said the 31-year-old Scot would also be taking part in two test days in 2015 as well as doing work in the factory simulator.

Wolff drove in two free practice sessions this year, becoming the first female driver to take part in a grand prix weekend in 22 years.

“This is another step in the right direction for me,” said Wolff, who will work with race drivers Felipe Massa and Valtteri Bottas.

Williams finished third overall this season, their best performance since 2003.

Brazilian Felipe Nasr, who was test and reserve driver this season, has left to join Sauber. Williams did not say who the new reserve would be.

Meanwhile, Anthony Hamilton’s ‘Info Wing’ is to undergo a few design tweaks after a successful maiden track test in Abu Dhabi this week.

Force India ran the LED display system on top of one of their cars on the second day of the final two-day test of the season at the Yas Marina circuit.

Using information provided from race control, the aim of the concept is to provide to the viewing public positional data, along with other information such as tyre strategy and on-track flag condition.

The test, at least, highlighted to Hamilton, whose son Lewis was crowned Formula One world champion for a second time last Sunday, where areas of modification are required before more tests are done.

Hamilton said: “As I suspected the bright sunlight made it a bit difficult to see the LEDs when the cars were out on track.

“Nevertheless it was a good test, and it bodes well for the new version.”
