Kimi Raikkonen announced his return to Formula 1 in some style as he posted the fastest time in the first day of pre-season testing at Jerez.
The 2007 world champion has returned to the sport after two years away and despite having limited time in the 2010 Renault, he looked sharp as he got to grips with Lotus' E20 at the Spanish circuit.
It was an impressive morning for the Finnish driver as he topped the timesheets with a smart 1:19.670, which same on the medium Pirelli tyres, and his time was never matched as the afternoon proved slower than the morning.
In total he completed 50 laps before lunch with a further 23 in the afternoon and he will return on Wednesday as Lotus are keen to give him as much track time as possible.
Paul di Resta posted the second fastest time of the say with Nico Rosberg third in Mercedes 2011 W02.
The Toro Rosso of Daniel Ricciardo was fourth fastest in the morning but it was Mark Webber in the Red Bull RB8 who came through to set the fourth best time of the day, pushing Ricciardo down to fifth.
Sauber's Kamui Kobayashi experienced some problems, first with his rear brake duct before he ran out of fuel and he had to settle for seventh, just behind Michael Schumacher who took over from Rosberg in the afternoon session.
Jenson Button was eighth fastest in his McLaren with Felipe Massa ninth for Ferrari home, while Heikki Kovalainen failed to see out the session after Caterham's starter shaft broke.
Pastor Maldonado completed just 25 laps on his way to 11th ahead of Pedro de la Rose in the HRT.
