Stefano Domenicali said: "the key objective we have is of immediately delivering a competitive car", as the car was 1.5 seconds off the pace at the start of the 2012 season.
Unlike having 7 drivers in 7 races like in 2012, Alonso think that the big teams will dominate and Ferrari "have to be one of them".
Gary Anderson, the BBC F1 techincal analyst said: "there are some very positive aspects of the new Ferrari - and some that I'm not quite as excited about.
"The rear-end treatment, from the back of the engine, looks like a positive step forward."
"I was very critical of their car in that area last year - it was messy, with radiator outlets disrupting the airflow."
"It's much cleaner this year, with a much more aggressive treatment of the 'coke-bottle' area where the bodywork sweeps in between the rear wheels, an area they neglected in 2012. And it looks as if they have a very small gearbox, because the bodywork at the back is very low."
"That's all good for keeping the airflow as effective as possible in a crucial area and it looks like a big step forward."
One of the most noticeable things is that the stepped nose from the F2012 has vanished, and replaced with a vanity panel.
