Sauber pair Felipe Nasr and Marcus Ericsson are hopeful that upgrades will boost the squad during the second half of the 2015, having slipped down the order in recent races.
Sauber bagged 14 points in the season-opening Australian Grand Prix but have added just eight to the tally since, dropping down to eighth place in the Constructors' championship.
The team is set to receive an engine update from Ferrari for the next race in Belgium, with an aerodynamic package scheduled to be introduced in Singapore.
"During the second half of the season there are some tracks on which I will get my first taste in a Formula 1 car," said Nasr.
"For example, the circuit in Japan is one I have not driven on yet. The Mexican Grand Prix will also be on the calendar again, which is new for everyone.
"I am looking forward to running the car with the updates. As we have not driven the car yet, we cannot precisely predict what it is going to be like.
"The target is to put us back into the points. In the championship we have dropped back down, and I think it will not be easy to move up. However, I am still confident the updates will help us to be in a better position."
"It is encouraging having updates coming in Spa-Francorchamps and Singapore," added Ericsson.
"With that being said, our objective is to be back on a level from which we are able to fight for points. If that happens, we have to wait and see how it goes. We are going to work hard to extract the maximum out of our updates."
