Jenson Button's perfect start to the season continued as he won the Malaysian Grand Prix after the race was stopped because of heavy rain.
Brawn GP's English driver was leading when the race was stopped followed by BMW Sauber's Nick Heidfeld and Toyota's Timo Glock in third. World champion Lewis Hamilton was seventh.
Drivers earned half points.
After an action-packed first race of the season in Australia - which Button won convincingly - this race lived up to expectation.
Yet safety was the prime concern as, following the arrival of the red flag after 31 laps, motorsport's world governing body, FIA, decided the race could not be restarted as the allocated time was fast running out when lightning and torrential rain had eventually passed.
The decision was backed by most drivers, some having called for a suspension earlier over their team radio because of atrocious conditions even before the safety car came out.
"The visibility is nothing," said Renault's Fernando Alonso before the race was officially called off.
