Williams has set set-up a two-day test in which it will evaluate Paul di Resta and Robert Kubica, with the lingering possibility that one will take up a race seat next season. Di Resta has raced for Williams this year, stepping in for an unwell Felipe Massa at the Hungarian Grand Prix.
The Scotsman made his debut in Formula 1 at the 2011 Australian Grand Prix for Force India. He spent three years racing for the Silverstone-based team, before returning to DTM in 2014, a championship that he had already claimed a title in (2010). In 2016, he joined Williams as a reserve driver.
Kubica has been eyeing an F1 return for years after his life-threatening rally crash in 2011. The Pole had part of his forearm amputated, which cast huge doubt over a return to motorsport's pinnacle. The 32-year-old has done extensive testing with Renault this year, but an opportunity to race for the French squad closed up when it announced Carlos Sainz for 2018.
Williams is looking for an experienced driver to continue to partner Lance Stroll next year, with current driver Felipe Massa already in the hunt. Williams will host a single day test for Kubica at Silverstone in its 2014 car, before travelling to the Hungaroring for a two-day test, with Kubica and di Resta handed one day each.
