Marcus Ericsson has signed a contract extension with Sauber.

Sunday's season finale in Abu Dhabi will mark the end of the Swede's second season with Sauber, having made his Formula One bow with Caterham in 2014.

He collected nine points in 2015 but has been unable to add to his tally this year and has been outperformed by team-mate Felipe Nasr.

But Sauber have kept faith in the 26-year-old, who opted to retain him in the paddock for a third season.

"It is great news that I will be racing for another year for the Sauber F1 Team. I have spent two years with Sauber now and I really feel at home," Ericsson said via a Sauber news release. 

"A big thanks to everyone within the team for trusting in me again. From a personal point of view, I have developed a lot as a driver during my time at Sauber.

"We have had ups and downs, but we always stick together and work as hard as we can. Since the new ownership, there has been a positive push in the team, so it will also be exciting to go into this new era.

"Many motorsport experts are becoming part of Sauber, which is a good sign for the future. For 2017 my aim is to build on my performance from the second half of this season, and to continue working hard with the team.

"I cannot wait for the 2017 season, so that we can make our way up to the midfield with the objective to score points on a regular basis."

Sauber have yet to fill their other driver's seat for 2017. Manor have the only two other remaining seats for next season.
