Monisha Kaltenborn, the Sauber Team Principal, admitted that the team is struggling financially, but added that she hopes to find a solution soon.
Sauber have struggled on and off the track so far this season, claiming only seven points after nine races while rumours of the team failing to pay Nico Hulkenberg surfaced during the German Grand Prix.
"We have very openly said we are going through a difficult time but we are confident we will be out of it soon," Kaltenborn told ESPN.
"That's it, there is nothing more to say. Clearly when you have limited resources you cannot develop as much as you want to and that's it."
There is, however, also rumours that Kaltenborn is close to landing a major sponsor and she is confident that the team will continue to run as normal next season.
"It's never ideal, but I don't think we are jeopardising next season," she added.
Several of the smaller teams are expected to struggle with developing engines under the 2014 regulations and Kaltenborn believes F1 should work together to help them.
"We all endorsed these changes and what we should really do is not wait until it is too late for some teams," she said.
"In many situations we always wait for something to happen and then react, but in this case there are so many teams struggling that I think we should really do something about it before anything happens. We shouldn't always wait for the big bang."
