Clos will take over Narain Karthikeyan’s car in the first practice session on Friday and drive alongside Pedro de la Rosa.
The Spanish driver appeared for the team in the Young Driver Test last year.
Clos said: “I’m delighted to have this opportunity. It’s something I’ve fought for all my life; to make my debut in Formula 1 and, above all, to be able to do it at the Circuit de Catalunya which is something very special for me.
“Besides, I’m extremely lucky to be able to do it with a Spanish team, alongside another Spanish driver who I admire and at home. I can’t ask for more! It’s the ideal situation and I’m proud to be where I am with the people who have always been with me and still are.
“I hope to extract a lot of data from this practice session, contribute with positive things to the team and do my job in the best way I can. I feel 100% ready and I can’t wait for the moment I step into the car and hit the track.”
Clos joins Alexander Rossi who will also be making his first participation in an F1 race weekend on Friday.
