GP3 racer Adderly Fong will drive Sauber's C34 during part of Tuesday's post-race Pirelli tyre test in Abu Dhabi.
Fong, who has acted as a Lotus development driver this year, will share duties with Marcus Ericsson at the Yas Marina Circuit.
Fong previously tested Formula 1 machinery during practice for last year's Abu Dhabi Grand Prix, when he also ran for Sauber.
"I am very pleased and thankful to have another opportunity to drive for Sauber," he said.
"I will do my best to give valuable feedback. I am looking forward to it, as well as the aim of extending my superlicence after completing 300 kilometres.
"Last year it was great to have the chance to drive the Sauber C33-Ferrari during FP1 here at the Abu Dhabi Grand Prix. Now I am curious about testing the current car."
