In May 2010, Vergne was signed by Tech 1 Racing to contest the opening GP3 Series round in Barcelona. He was replaced by countryman Jim Pla for the next round in Turkey as it clashed dates with the British Formula 3 event at Hockenheim, but returned to the team for the following round in Valencia. However, in early July it was announced that Daniel Juncadella would take Vergne's seat at the team for the remainder of the season.
