The 2009 Malaysian Grand Prix was held around sunset, starting at 17:00 local time (09:00 UTC). This proved disastrous due to heavy rainfall. The race was red-flagged and ultimately not restarted due to the low light level making it through the clouds. The race ended on lap 33, and with the regulations requiring 42 laps for full points, both driver and constructor results were halved in relation to points.
