Romanian driver Mihai Marinescu has committed to a third season of Formula 2 ahead of the opening rounds at Silverstone this weekend.
The 23-year-old took his maiden win in the series on the way to fifth in last year's standings, having taken 11th in his rookie campaign.
"I enjoyed racing in the series, so it was a natural choice to continue here, in a friendly and familiar environment," said Marinescu.
"Of course I aim to win the championship and to take the big prize - the test with the Williams F1 car - but I learned that the championship is long, you need consistency and to work very hard, every day, to achieve this dream.
"I will do my work, I will try to be on the podium on almost every race and I will fight for race wins. If I will do my job perfectly, the big prize will come."
Series chief Jonathan Palmer sees no reason why Marinescu cannot be a title contender this year.
"He showed title winning potential last year with a superb maiden pole and lights-to-flag victory in Monza," said Palmer.
"Mihai was equally impressive during F2's winter test programme in Barcelona, ending second and third quickest, and I'm sure he will be a very strong contender for the championship title."
