Sauber's Marcus Ericsson is hoping that a big aerodynamic upgrade set for introduction in Hungary will help improve the Swiss outfit's performance.
The Hinwill-based team has been stagnant lately, although Pascal Wehrlein did bag a point in Azerbaijan, bring Sauber's tally to five points so far this season.
But ineffective previous updates of the C36 chassis coupled with an older-spec Ferrari engine have seen Sauber's pace progressively regress, a state of affairs which Ericsson hopes will reverse next weekend.
"I don't know exactly what the upgrade will be [but] it should be a good step," he told Motorsport.com.
"Hungary is a track where any downforce we can get is going to help you and is not that efficient for engines.
"So it could be a chance for us, if we get another step from the upgrade, we could be in the mix."
Ericsson considers Sauber's C36 as a good car, when the team succeeds in getting its set-up right.
"When we got the car working, like at Silverstone in the race, we could keep similar pace to the Haas cars, and [Stoffel] Vandoorne wasn't much faster," said the Swede.
"We are not too bad, when we get our car together.
"Hopefully in Hungary, where it's a bit less engine efficient, we can be a bit more efficient."
