After a frustrating run with just one point in eight weekends, the team made a significant step in Qatar, where Valtteri Bottas claimed eighth and Zhou Guanyu ninth.
The six points moved Alfa up to eighth place in the championship table, ahead of Haas, leaving it just seven points behind Williams.
While Williams has made it clear that it has switched its focus to the 2024 project its rivals Alfa and AlphaTauri have continued to bring new parts to the track.
Haas is putting a lot of faith in a major upgrade package that will be unveiled in Austin this weekend, adding an extra dimension to the battle for the minor placings.
“We are convinced that we can fight for P7 until the end of the season, based on our decision to keep developing the car,” Alunni Bravi told Autosport.
“But of course, we need to execute each race weekend a perfect race like Qatar, both from the team side and the driver side.
“Qatar was a good reward, it's been good for the team, for the confidence and for our drivers, after a tough period.
“But the championship is still long, five races with two other sprint sessions. So still room for improvement. We need to look ahead of us to find extra performance in the next race.”
