Another boss of the annual Malaysian Grand Prix has admitted Sepang should host a night race.
The circuit's boss Razlan Razali said last month that running a race under lights before the contract expires in 2015 could boost spectator numbers.
"Maybe this will attract a bigger crowd as the weather at night will be cool," he said.
Now, Sepang chairman Mokhzani Mahathir has told AFP news agency that the night race idea is "interesting".
In 2008, he had ruled out the idea as too expensive to implement.
But he told reporters on Tuesday: "In Qatar (for MotoGP) and Singapore, we see it works.
"I think a night race will be interesting. The F1 race at night will be cooler," added Mokhzani.
