Britain’s Jamie Chadwick will continue with the Williams driver development programme for a fifth season in 2023.
The three-time W Series champion will have “a personalised simulator program to aid in her progression and provide valuable support to the team’s race preparations,” a statement said.
Chadwick, 24, is racing in the American Indy NXT series, a feeder category for IndyCars, with Andretti Autosport.
“To be continuing my relationship with Williams is amazing,” Chadwick said.
Williams sporting director Sven Smeets said: “Jamie is an incredibly talented driver and an important role model in inspiring the next generation of females in motorsport.”
Chadwick won her third title in W Series – a women-only championship – in October after the final three races were cancelled because of funding issues.
Her move into the Indy NXT series, which is the second tier of the USA’s open-wheel racing format IndyCar, is a step up in speed from the W Series and includes 14 races – two of which are on traditional American oval circuits.
