D'Ambrosio chasing 2013 drive
Jerome d'Ambrosio is keen to race in F1 this season but concedes that securing one of the last two race seats is "difficult".
Having raced for Virgin, now known as Marussia, back in 2011, the Belgian driver was left without a seat when he was dropped by the backmarker outfit.
The 27-year-old remained in Formula One as a test driver after Lotus team boss Eric Boullier, who manages d'Ambrosio through Gravity Sport Management, signed him.
And although d'Ambrosio could retain his Lotus role, the 27-year-old, who contested one race in 2012 when he filled in for the banned Romain Grosjean in Italy, says he is keen to land a race-seat for this season.
"I continue to strive for Formula 1 because that's my thing," he told Le Vif.
"My management company is working hard but it is difficult since many experienced drivers have not yet got a seat. We shall see."
There are just two seats still unconfirmed for this season, one with Force India and the other with Caterham.
