Marussia has extended its contract with driver Jules Bianchi through the 2014 season.
Marussia announced Thursday, ahead of this weekend's Korean Grand Prix, that the Frenchman would be retained.
Doubts remain, however, about the future of teammate Max Chilton, with team principal John Booth saying the second driver would be announced later in the season.
"I couldn’t have wished for a more supportive environment in which to make my F1 debut and from the very beginning I have always felt completely at home with the team," Bianchi said. "We started the season very well and while the challenge has increased as the season has developed, we have learned important lessons together that will place us in a much stronger position next year when there are a lot of changes for the sport and the team to get used to."
Bianchi is part of the Ferrari Driver Academy and is considered one of the longer-term prospects for the Italian team, which will provide engines to Marussia next season when the sport switches to V6 turbo power.
