Felipe Nasr and Marcus Ericsson have been retained by Sauber for a second season.
Sauber have confirmed their driver line-up for the 2016 Formula One season by extending the contracts of current pairing Felipe Nasr and Marcus Ericsson.
The two drivers have impressed since joining the Swiss outfit for the current campaign, with both finishing in the top 10 at the season-opener in Australia and securing Sauber's first points since the 2013 Brazilian Grand Prix.
Further points finishes have followed for both Nasr and Ericsson, leaving them 11th and 16th respectively in the drivers' standings.
"The extension to the contract with the Sauber F1 Team is an important step in my career," said Brazilian Nasr. "During the first half of the season, in what is my rookie year, I was able to gain a lot of experience from a driving perspective as well as on the personal side.
"Finishing fifth at my first ever Formula One race in Melbourne in the Australian Grand Prix is so far my career highlight. Now I am looking forward to the second half of the season."
Swedish driver Ericsson added: "I'm very happy that the Sauber F1 Team has put its trust in my potential for another year.
"I had a great start from the very beginning, and it is worth mentioning my first points in Formula One that I scored right away during the season-opener.
"I am getting to know everyone within the team more and more, and feel I am being appreciated as a valuable driver."
The arrival of Nasr and Ericsson initially caused great controversy, with Sauber and Giedo van der Garde becoming embroiled in a legal dispute after the driver claimed he had been promised a seat for the 2015 season.
