A 'job well done' for Kubica in Williams test
Robert Kubica completed 100 laps of testing in Abu Dhabi as he strives to secure a Formula One return with Williams next season.
The Polish driver is among the contenders to be Lance Stroll's team-mate next season after Felipe Massa retired.
Kubica has not raced in F1 since suffering a serious arm injury in 2011, but was given a third testing opportunity by Williams at the Yas Marina Circuit.
The 32-year-old racked up more than circuits than any other driver testing the new Pirelli tyres behind the wheel of the FW40 for the first time on Tuesday.
Williams tweeted: "Over 500km under his belt in the FW40 and that's a job well done for Robert on day one of the #AbuDhabiTest #F1 #Kubica".
Renault reserve Sergey Sirotkin will also get an opportunity to impress the Oxfordshire-based team in Abu Dhabi on Wednesday, with Kubica returning to the track later in the day.
Kubica was previously evaluated by Williams at Silverstone and the Hungaroring last month.
