The Haas F1 team will announce one of its 2016 drivers on Tuesday in a press conference at its base in Kannapolis, North Carolina.
Haas is set to join the F1 grid next year and its driver line-up has been the source of much speculation. Lotus driver Romain Grosjean is expected to be one of the two and has said in recent weeks that he is satisfied his future is secure.
"I'm happy, in my mind it's all done and you will know soon," Grosjean said on Thursday in Suzuka when asked about his future. "You can always change your mind but as I said I think I'm pretty pleased with my choice."
Ferrari reserve Esteban Guttierez is tipped for the second drive due to the new team's links with Maranello. Haas will run Ferrari engines next year along with as many shared components as is allowed under the regulations.
Both team owner Gene Haas and team principal Guenther Steiner will be in attendance at the announcement.
