Formula Renault Eurocup race winner Luca Ghiotto will graduate to Formula Renault 3.5 with Draco for the 2014 season.
The Italian, who finished ninth in the Eurocup last year and second in the FR2.0 ALPS series, tested for Draco post-season, and completes the team's line-up alongside Pietro Fantin.
Team boss Guto Negrao hinted that the 19-year-old was likely to be part of a longer-term deal beyond this year.
"Luca's programme will be aimed to a steady progression, something we deem essential for a rookie," he said. "That's why he's in our plans for 2015 too.
"He surprised us in testing with an extremely focused and professional approach, something we didn't expect for such a young driver.
"That's what convinced us that he was the right guy for Draco, and we are really looking forward to the start of the season."
