Kimi has taken step forward – boss
The Finn went through a difficult period of competitiveness following his debut win for the Maranello team in Australia.
But "everyone can see he has made a step forward in performance," Ferrari's sporting director Stefano Domenicali said at Silverstone.
Italian Domenicali, however, said he is only "50 per cent" happy in Britain, after Felipe Massa's victory chances stalled with his F2007 on the grid.
He said: "With the performance we have had this weekend, we should be celebrating a one-two.
"Such errors should not happen," Domenicali added, explaining that he did not yet know the reason for the problem.
"We are in good shape, even though it is a shame we are so far behind, because the gap to Hamilton is pretty big.
"But we will keep pushing and put pressure on our competitors, who are still very strong. We must be aggressive."
