Williams test driver Susie Wolff has announced her competitive retirement from motorsport at the end of the 2015 season.
Wolff, 32, has been with Williams since 2012, firstly in the role of development driver before she was promoted to the squad's test driver at the start of the year.
Wolff has participated in four practice sessions for the team alongside test days and duties in the outfit's simulator.
"I’d like to thank Williams for the opportunity they have given me over the last few years which has allowed me to achieve my dream of driving a Formula 1 car," she said.
"It has been great to work with everyone at the team, both at Grove and track side, and I’d like to thank everyone who has been part of my journey at Williams.
"I am now closing this chapter but looking forward to new challenges in the future."
