Robert Kubica has completed a second test for Williams, with the team assessing the driver's abilities at the Hungaroring as he tries to make a full-time return to Formula 1 in 2018.
The 32 year old drove a 2014-spec Williams FW36 at the circuit which is the venue for the Hungarian Grand Prix, having driven the same car at Silverstone only six days ago.
Williams stated that the Pole "completed another productive day" of testing but remained coy as it continues to evaluate the driver as a possible replacement for Felipe Massa for next season.
Paul di Resta, who drove for Williams at the Hungaroring earlier this year, is also in contention for a drive with the Grove-based outfit, and will test for the team tomorrow at the same venue.
Kubica drove in Formula 1 from 2006-2010 and was one of the most exciting prospects on the grid. A rally accident ahead of the 2011 season however, cut his career short and he has since remained off the grid. A return to the top tier of motorsport looked unlikely for the Polish driver until 2017, with a number of tests with Renault putting him back in contention for a future race seat.
