Formula One 'Iceman' Kimi Raikkonen lapped fastest for Lotus in the Bahrain desert heat on Friday after Ferrari had set the early practice pace.
The winner of the season-opening Australian Grand Prix is just four points behind Red Bull's triple world champion Sebastian Vettel after five of the 19 races and hitting the sort of form that brought him the title as a Ferrari driver.
The 38-year-old 2007 Formula One world champion announced this week that he was leaving Ferrari for the second time in his career and had signed a two-year contract with the modest Sauber team, where he started in the sport back in 2001.
A decade on from their last driver's title, courtesy of Kimi Raikkonen in 2007, Ferrari emerged from eight days of testing in Spain with the fastest lap times coupled with impressive reliability.
