Williams has signed a young driver it has described as "one of the foremost young talents in motorsport" in 16-year-old Zak O'Sullivan.
O'Sullivan, who won last year's GB3 title [formerly the British F3 championship] by a record margin of 164 points, has joined the team's Driver Academy.
After additionally finishing runner-up in the British F4 championship in 2020, O'Sullivan's rise will continue this year as he is to compete in F3 with Carlin which has also supported him over the past two seasons.
O'Sullivan is to be fully integrated into the team, both trackside and at the factory at Grove where he will conduct simulator work and provide feedback for car development.
O'Sullivan said: “I’m honoured to have been selected as a Williams Racing Academy driver.
"This is an incredible opportunity and I can't thank Jost [Capito, team principal], Sven [Smeets, sporting director] and the whole team enough for their faith in me.
"Williams Racing is one of the most successful and respected teams in Formula 1 and have nurtured some of the greatest talents in the sport.
"I’m also so pleased to be continuing my relationship with Carlin and stepping up to F3 with them this season. This will be my third year working with the team and I am looking forward to the challenge ahead.”
Believing O'Sullivan's GB3 campaign "speaks to his natural talent", Smeets added: "The team can attest to his capability, drive and professionalism having seen him drive the simulator in Grove.
"I’m very much looking forward to seeing him take on F3. I know he’ll prove a formidable competitor.
"We’re now looking forward to working alongside Zak to support his development and progression, a role that we’re proud to play in a talented young driver’s career.”
