GP2 driver Jordan King will make his practice debut for Manor at this weekend's U.S. Grand Prix.
King has been a Manor development driver since 2015 and is also the son of team chairman Justin King. He has taken part in three tests for Manor in the last 12 months, including the in-season tests in Barcelona and Silverstone this year, but this will be his first outing in grand prix practice session.
"First of all, I'd like to thank the team for making this possible," he said. "It's another big step in the right direction for me, after two really positive tests in the MRT05 which paved the way for this opportunity.
"It's a dream come true, but at the same time I have a job to do in the car on Friday and I want to make sure I give the team plenty of quality feedback and data to help with their USGP challenge.
"There's quite a lot to cram into 90 minutes. I'll be exploring the balance of the car and correlating that with the team's simulation work. There'll be some new components to evaluate, along with the tyre specifications for this event. I'll also be learning the circuit and getting up to speed with the car, which has been developed quite a bit since I last drove it at Silverstone. I can't wait!"
Manor racing director Dave Ryan added: "It will be good to give Jordan his first FP1 session. He's done a really great job in his Development Driver role and this opportunity was a planned part of his programme with us. We look forward to getting his feedback and this further opportunity to appraise his performance in the MRT05."
King is currently fifth in the GP2 drivers' standings with two race wins and five podiums to his name. He has been linked to a Manor seat in 2017 if either Pascal Wehrlein or Esteban Ocon move up the grid next season.
