Ferrari release 'really sexy' new F1 car, but only target two Grand Prix wins during 2015

New Ferrari team principal Maurizio Arrivabene has put himself in the firing line by demanding two grand prix wins from the upcoming Formula One season from a car he has described as "really sexy".

Arrivabene was appointed at the end of last year on the back of Sergio Marchionne's vow to "kick some ass" following his arrival as Ferrari chairman in October.

Marchionne ousted Marco Mattiacci after just seven months in charge, with the former car salesman seemingly out of his depth after he was taken on in April as replacement for the axed Stefano Domenicali.

Marchionne is determined to end Ferrari's miserable lack of success as the fabled marque are now without a title for six seasons.

Worse still is the fact it is almost two years since Ferrari last won a grand prix, stretching back to the 2013 race in Spain when Fernando Alonso was at the wheel.

Whilst Arrivabene appreciates Ferrari will not be challenging Mercedes for the championship this season, he is expecting to see one of his drivers in newly-recruited Sebastian Vettel or Kimi Raikkonen standing on top of the podium.

"I'm just realistic," said Arrivabene.

"Nobody has the magic to change things when things are unchangeable.

"We applied certain modifications that in our opinion are quite interesting.

"With that I don't want to say we are going to win the World Championship, but for sure we are committed at least to win two races."

In revealing the SF15-T on Friday that will make its debut on Sunday on the opening day of the first pre-season test in Jerez, Arrivabene remarked: "Enzo Ferrari said a long time ago the best car is a winning car.

"Last year we had an ugly car and it was a non-winning car on top of this.

"I like this year's car in terms of aesthetics. I don't know about the performance, but it's really sexy."

Arrivabene has made it clear what he expects of four-times champion Vettel and Raikkonen as he said: "They have to work together as team-mates, they have to work with the team.

"Things I want to avoid, talking about the overall team and not only about the driver, is that everybody is pushing and working together in the same direction. I'm expecting the drivers to do the same."

Like Arrivabene, Vettel recognises any upward progress for Ferrari will take time.

The German, who left Red Bull at the end of last season following a difficult year when he became disillusioned with the change in rules that affected his car, said: "I am confident we are going in the right direction.

"But it would be wrong to think a lot of us because we are coming from a 2014 season where there was one team very dominant.

"It will be difficult to be right there from the beginning, but the main target is to really work together, make progress and catch up more and more.

"Clearly if the situation is like last year it will be difficult to fight for victory, but it is our goal - we are not here to finish second."

Raikkonen is convinced he and good friend Vettel can work together to push Ferrari back towards the front of the grid.

"It will be interesting working together for the first time, but we have a good understanding which will help," said 2007 world champion Raikkonen.

"The main aim is to get the team moving forward. Then we will try to fight against each other, in a good way, to push each other on to do better things.

"Sebastian has had a great career so far, and he has a few more trophies than I do.

"He still has a long career ahead of him and I'm happy for him to join. We'll both try to do well and put the Ferrari at the front."
