Williams has confirmed that Robert Kubica and Oliver Rowland will share driving duties at the in-season Barcelona test in two weeks. Kubica will also drive the first free practice session during the F1 weekend on the Friday before the test.
The first free practice outing will be Kubica's first F1 weekend appearance since the Abu Dhabi Grand Prix in 2010. Having driven the car at the pre-season test earlier this year, the Pole will be racking up more laps for the Grove squad, who scored its first points of the year in Azerbaijan last weekend.
Rowland was named as a Williams 'young driver' in February and will get his first taste of the 2018 car around the Circuit de Barcelona-Cataluyna. The Briton raced in Formula 2 last year, finishing in third place behind Charles Leclerc and Artem Markelov.
Force India has already announced its test line-up, as Nicholas Latifi and Nikita Mazepin share one car. George Russell will also drive a second VJM11, testing tyres for Pirelli.
