Ferrari are under pressure to improve their Formula One car quickly after a stuttering start in order give Fernando Alonso and Kimi Raikkonen a realistic world title chance.
Team principal Stefano Domenicali told the Formula One website the team must "make sure that we give them the best car we can".
"That is the urgent need, and it has to happen very soon."
Alonso placed fourth in the opening two season races in Australia and Malaysia, with the Bahrain race next on Sunday.
Raikkonen, who won the last drivers' title for the scuderia in 2007 and returned to the team this season, was seventh in Australia and 12th in Malaysia.
