Sergey Sirotkin is confirmed as the second Williams driver in the new season of Formula 1 where his team-mate will be Lance Stroll while Robert Kubica has been given the role of a development and reserve driver.
Williams held keys for last seat in F1 2018, with main candidates being Sergey Sirotkin, Robert Kubica, Daniil Kvyat and Paul di Resta.
It took weeks to agree on the contract details between Williams and the Russian driver who signed a multi-year contract according to Autosport.
Williams will have the least experienced driver in 2018, as the 22-year-old Sirotkin will join the 18-year Stroll, the youngest driver in F1 history who started the race from the front row.
“After an intensive evaluation process, I’m thrilled to have completed driver line-up and I’m excited about new season,” said Claire Williams.
“We’ve had time to explore all available options and I’m sure Lance and Sergey can make the best possible results for the team.”
Technical Director Paddy Lowe praised his new driver.
“Sergey has delighted the team with his speed and talent, technical information and working habits, both at the factory and on the track in Abu Dhabi,” Lowe said.
Sirotkin, who has tested the Renault F1 team for the last two years, is thrilled to have grabbed the last free seat in Formula 1 2018.
“To say I’m happy and proud to have come to a famous team like Williams is an understatement,” Sirotkin said.
“It took a lot of work to come here where I am now and I’m really happy and grateful to everyone involved in this.”
