Sauber are the only team yet to score in 2016. They came close to closure earlier in the season but fresh financial investment saved them, but so far they have failed to improve their on track performance.
"We had a few updates on the floor and it’s been an improvement but we’ve been struggling a bit more with the car's balance," said Ericsson.
"Looking back to the previous race weekends, we clearly made steps in the right direction, but we still need to find more pace in order to fight for points," he admitted.
Although unsure of a points finish, the Swede is looking forward to returning to the United States this weekend.
"I am looking forward to going back this year, as I like this track a lot," he is quoted by F1i. "It is a nice event at the circuit, and, as well as that, Austin is a great place to be."
