Lewis Hamilton and the Ferraris of Fernando Alonso and Felipe Massa have all gone out in the opening qualifying session ahead of this Sunday's Malaysian Grand Prix.
Rain created chaos in Q1 and McLaren and Ferrari both left it too late to set times to progress. Initially it looked as if the rain would clear, but then another storm hit the track, and that left Hamilton, Alonso and Massa in the drop zone.
Jenson Button also had problems, and while he put in a time to get through to Q2, spun off into the gravel and was unable to continue. He will take no further part in qualifying.
Jarno Trulli also failed to make it through to the next part of qualifying in his Lotus, as did the Hispania cars of Bruno Senna and Karun Chandhok. Lucas di Grassi was late get out as his mechanics were still working on his Virgin car.
Robert Kubica was quickest for Renault - on a 1m 46.283s - followed by Pedro de la Rosa, Sebastian Vettel and Vitaly Petrov. Kamui Kobayashi completed the top five.
