Ferrari unveiled their car for the new season on the internet Friday, the legendary Italian stable counting on the SF15-T to bring back the glory years after a miserable 2014. Fernando Alonso's lowly ninth place in the season-closing Abu Dhabi Grand Prix completed a wretched year for the men from Maranello, their first winless season since 1993. Ferrari's lacklustre performance in taking only fourth in the constructors title race triggered sweeping changes at their Italian HQ in a bid to put the team back at the top of Formula One. In November, team chief Marco Mattiacci was sacked after just seven months in the post with Maurizio Arrivabene appointed in his place. That switch came days after Red Bull's four-time world champion Sebastien Vettel was signed on a three-year-contract to replace Alonso after the Spaniard's move to McLaren.
