Ferrari team principal Marco Mattiacci insists his team can pull off a "360 degree" turnaround and compete at the front of the grid.
The Italian outfit have been well off the pace of Mercedes so far this campaign with Fernando Alonso 87 points behind Championship leader Nico Rosberg with his Ferrari team-mate Kimi Raikkonen another 60 points adrift.
The Scuderia, though, have improved in recent races with Alonso finishing second behind Daniel Ricciardo of Red Bull in Hungary before the summer break.
Mattiacci admits they still have a "huge amount of work" to do, but is confident they can do it.
"We need to improve the car at 360 degrees," Mattiacci is quoted as saying by Crash.net. "It's not just the power unit, it's not just aerodynamics, it's not just the chassis; it's the team, the car... so it's a huge amount of work that has to be done.
"Am I confident? I'm confident about the team spirit that we're building and the quality of the people that we have - the strength and the plan that we have. That's why I'm confident."
