Sepang will not modify its circuit in order to organise a formula one night race, organisers of the Malaysian grand prix said on Friday.
Melbourne - in a similar timezone - is coming under increasing pressure from Bernie Ecclestone to install floodlights and host its race at night, to better serve the core live television audience back in Europe.
But Razlan Razali, Sepang chief executive, said the F1 chief executive is putting "no pressure" on Malaysia, whose 2012 race will be held next weekend.
"Why do a night race when most other circuits do not do it?" he told reporters.
Already, Singapore hosts its annual street race under lights, while the Abu Dhabi grand prix begins at twilight and concludes at night.
