Lotus driver Kimi Raikkonen continued his good early season form, topping the time sheets after the second free practice session in the Formula One Malaysian Grand Prix at Sepang.
Raikkonen leads the driver's standings after winning the Australian Grand Prix with a smart two-stop strategy.
On a rain hit second session, the former world champion was the fastest in a time of 1:36.569, edging out Sebastian Vettel and Felipe Massa of Red Bull and Ferrari respectively.
Raikkonen known for his deadpan yet incredibly funny responses was at his best following Friday practice.
"Look at this place -- it is hot, it is humid and the track is completely different," he said. "On top of this we could see rain at any point of the race, so how should I know what is happening on Sunday afternoon?
"The only thing that I can say right here right now is that the car is good, that the team is working fantastically and that I want to keep the lead in the drivers' standings. Let's see where these factors will bring us in the race."
Raikkonen believes the hot weather will have a different impact on the tyres to the ones in Melbourne and his team will need to ensure they take that into account going into the qualifying session and then the race Sunday.
"It is the first time that we really run in hot weather, so we have to setup the car carefully to make the tyres work to our advantage in a long, demanding race," he added.
"At the moment I would say that it is trial and error for all of us, and the more you are able to try the more you have the chance to eliminate any errors. It looked good for us this afternoon, but it is Friday so it doesn't mean much.
"It is humid and so probably not the easiest place to be, but the track is nice. And the conditions are the same for everybody -- so why worry about it?"
