Pietro Fantin will partner Antonio Felix da Costa at Caterham Arden during the 2013 Formula Renault 3.5 season
Fantin, 20, will graduate to FR3.5 after finishing in sixth position in the 2012 British Formula 3 championship.
The Brazilian, a race winner in his two season in British F3, joins da Costa at the team after the Portuguese was confirmed on Wednesday.
"Formula Renault 3.5 has always been in my plans, for a two-year project, because of the car and high level of the competition," he said.
"As a rookie, I hope to learn a lot, but also with the real target of being in the top 10, finishing all races and constantly scoring points.
"Arden Caterham had a great performance last year, and they always have a competitive car, so I believe this year won't be different.
"I knew [Arden sporting director] Julian Rouse before and my first contact with the team at Barcelona test was really good."
