Antonio Felix da Costa and Robin Frijns will drive for Red Bull during the young driver test at the Yas Marina circuit in Abu Dhabi.
Frijns, who was crowned Formula Renault 3.5 champion on Sunday, will get the test as an award for his title.
Dutchman Frijns will also be testing for Sauber in Abu Dhabi.
Da Costa, who is a member of the Red Bull Junior team, finished third in this year's GP3 championship and won four of the last FR3.5 races this season, including both heats at Barcelona last weekend.
The Portuguese, who finished fourth in the championship, recently drove a Red Bull RB7 at a show car event in Seoul, Korea.
The young driver test takes place at Yas Marina from 6-8 November.
