The car's livery has less white sections than its predecessors, with Ferrari seemingly veering back towards its traditional red livery, while the SF71H is the first auto not to feature Santander as a sponsor, following the Spanish financial giant's decision during past year to pull the plug on their Formula 1 involvement.
The major sponsor of the team, Spanish bank Santander, no longer is on the auto, making the new Ferrari very red in its livery.
Ferrari has unveiled its 2018 Formula One vehicle - the SF71-H - at an event at its headquarters in Maranello. "The SF71H has a tighter auto body and has been built to perform in high-speed circuits", said Ferrari's technical director, Mattia Binotto.
"(The car) looks nice and usually when it looks nice, there's speed also", added Raikkonen.
The first chance to measure up against Mercedes' new auto will come in preseason testing next week in Montmelo, Spain.
Raikkonen said "it's an excellent auto, and our aim is to be faster" this year than last, when the Ferraris trailed the Mercedes on the faster circuits.
"The most visible is the Halo".
Vettel said "we'll get used to the new cage", dubbed Halo, which is "much less intrusive than I thought".
The Italian team have not won the constructors' title since 2008 but there is renewed hope that their new SF71H auto can deny Mercedes a fifth win in five years.
"The real magic happens underneath but every little detail matters, every part can make a difference, and this year's vehicle is a big step from last year's one".
The season opens on March 25 at the Australian Grand Prix in Melbourne.
