Third in Sunday's Monaco Grand Prix was enough for Alonso to take over sole ownership of the championship lead, three points ahead of Red Bull duo Sebastian Vettel and race-winner Mark Webber.
It is a remarkable achievement for Alonso and Ferrari, who at the start of the season appeared to be hopelessly cut adrift with a radical-looking car that had been roundly criticised by fans and the media.
Alonso's talent alone held the team together over the first few grands prix, winning a wet race in Malaysia before the Maranello marque at last saw some light at the end of the tunnel in terms of car development.
Although there have been six different winners of the opening six races for the first time in F1 history, consistency has so far been the key to Alonso's drive to the front of the pack.
"I was happy all weekend," said Alonso, whose team-mate Felipe Massa comfortably achieved his best result of the season with sixth.
"On Saturday I noticed some disappointment around the result in qualifying.
"Because we had been strong in free practice people expected us to be fighting for better positions in qualifying.
"But inside the team we were extremely happy. We were fifth and seventh, with both cars in Q3 for the first time this year after fighting to get through in some races a month ago.
"So we definitely had a very strong weekend with good qualifying positions and good race positions as well.
"We even overtook other teams in the constructors' championship with some good points,.
"So I'm happy for that, happy for the direction and momentum we seem to have retained from the Mugello test (at the start of the month).
"Everything seems to work, unlike at the start of the season when some of the updates were negative and we were a little lost.
"We are still not the fastest out there, so the pace is something we need to improve, but I'm happy with the direction we are going in.
"Everything we put on the car now seems positive."
Team principal Stefano Domenicali is relatively content enough, too, but readily admits Ferrari have nowhere near realised their aims or potential for the season.
Domenicali said: "In terms of pure performance of the car we had a very difficult start, but now I am very happy we are leading the championship.
"With such a close championship we need to make sure we don't lose points because if you do it is very costly with so many competitors and drivers fighting for the win. You have to be always there.
"On the other hand we have a situation where we are not happy because we want to improve the car.
"Other cars have been on pole position, but we have not, so that has to be a target for the team.
"If and when we are fighting for pole, or we are on pole, then the race is totally different.
"This is something we need to keep focusing on, to make sure we are working in that direction.
"At the moment I feel everyone at home is working to make sure that every race we keep on improving the performance on the car."
