After a temporary incursion from Sauber on Day Three, Ferrari resumed their role at the top of the charts on the fourth and final day of Formula One testing sessions at Jerez, Spain, with Kimi Raikkonen posting the fastest lap time of 1:20.841 for the day. That time from the 2007 world champion was the fastest of the week and finished off a session dominated by Ferrari, who posted the fastest lap times for three of the four days on the test track.
Second-fastest time on the day belonged to Marcus Ericsson of Sauber – who was a distant full second behind Raikkonen.
The first race of the 2015 Formula One racing season takes place in Melbourne, Australia on March 15, 2015.
