The winter break for the GP2 Series is over and teams and drivers of the top developmental championship are finally ready to go back on-track.

The 2013 season is set for an official kick-off at Jerez de la Frontera, as the Spanish track will be hosting the first round of collective testing of the year.

Trident will be fielding the team's two cars for Nathanael Berthon and Robin Frijns.

Berthon, a 23-year-old from France, has raced in the 2012 GP2 Series and scored two podium finishes at his debut season. Dutch 23-year-old racer Frjins has recently been signed by Sauber F1 as a third driver. He will be driving a GP2 car for the first time after his win in the 2012 Formula Renault 3.5.
