Williams confirms Sirotkin for 2018 seat
16 January 2018 – Williams has announced that Sergey Sirotkin will partner Lance Stroll for the 2018 campaign, with Robert Kubica, on the comeback trail after sustaining serious injuries in a rally crash, missing out.
Russian racer Sirotkin, 22, impressed Williams with his performance at the post-Abu Dhabi Grand Prix tyre test, where he ran alongside Kubica.
Sirotkin placed third overall in GP2 in 2015 and 2016, and acted as a test driver for Renault in 2017, making several practice appearances.
"To say I'm happy and proud to join such a famous team like Williams is an understatement," said Sirotkin.
"It took a huge amount of work to get where I am, and I'm really happy and thankful to everyone involved.
"The result of our combined efforts has helped me achieve my dream, and rest assured the team can rely on me to deliver my best."
Deputy Team Principal Claire Williams added: "After an extensive driver evaluation process, I am thrilled to have our 2018 line-up finalised, and I'm excited to see what next season brings.
"We have taken our time to evaluate all the available options, and I'm confident Lance and Sergey can deliver the best results for the team.
"The Williams philosophy has always been to promote and develop young talent and Sergey fits right into that ethos.
"Lance has had a record-breaking debut season, and with a year now under his belt, he will be ready to hit the ground running in 2018.
"We have a talented driver line-up for 2018, that we are confident will deliver some exciting results for the team."
Kubica, 33, had been pushing for a full-time return after several test runs with Renault and Williams, but ultimately missed out on a 2018 seat.
He will, though, act as Williams' reserve and development driver in the new season.
