Kubica completes first test with Williams at Silverstone, another run proposed
Robert Kubica tested a non-Renault Formula 1 car for the first since his return to the pinnacle of motor racing at Silverstone, on Wednesday.
The Polish driver was behind the 2014-spec Williams car in an all-white livery, which is primarily used by Lance Stroll to familiarise himself with certain circuits.
Williams is currently evaluating Kubica along with its reserve driver Paul di Resta for a possible seat alongside Stroll in 2018, with Felipe Massa also in the reckoning.
The world champion outfit did not reveal any details about Kubica's lap numbers or lap times, but attributed his running to be 'successful' in the Williams FW36.
F1 website reports of another test for Kubica in Hungaroring next week before the US Grand Prix, where one day will be kept for di Resta.
The 32-year-old's Budapest running will be his second since August, when he drove the 2017 Renault car for the first time in the post Hungarian Grand Prix testing.
After a failed attempt to return with Renault in 2018, Kubica hired 2016 F1 champion Nico Rosberg to his management in a bid to further press to land himself a lucrative seat.
