"We enjoy having them in the team and they give it a positive boost.
"Despite their young ages, they work very professionally - on as well as off the track."
Nasr, who finished an impressive fifth on his grand prix bow in Australia has been linked with a seat at Williams should Valtteri Bottas replace Kimi Raikkonen at Ferrari next term.
But the 22-year-old Brazilian, who has also scored points in China and Monaco this season, insisted he is pleased to have signed a new deal with Sauber.
"It is great to be driving another season for the Sauber F1 Team," Nasr said. "The extension to the contract with the Sauber F1 Team is an important step in my career.
"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. My objective is to support the team as best I can, and also with regard to the development of the new car."
Ericsson, who combined with his team-mate brings in around £20million of sponsorship to Sauber, added: "I'm very happy that the Sauber F1 Team has put its trust in my potential for another year.
"I am getting to know everyone within the team more and more, and feel I am being appreciated as a valuable driver.
"I feel honoured to be part of the Sauber Motorsport family, and I will continue to do my very best to succeed."
