Robert Kubica on Thursday said it has not been decided if his BMW-Sauber will be fitted with a KERS system in Malaysia this weekend.

Last weekend in Australia, his teammate Nick Heidfeld used the controversial energy re-use power boost technology but Pole Kubica - who weighs significantly more than the diminutive German Heidfeld - did not.

BMW has said it is assessing using KERS this season on a driver-by-driver and circuit-by-circuit basis, weighing up the power benefit against the compromise in weight distribution.

KERS is expected to be more beneficial this weekend than in Melbourne a week ago, due to the Sepang circuit's longer straights.

But Kubica, 24, said in Malaysia: "I've not decided yet (about KERS). I could have it and I could not have it. If I am not using KERS there is a reason."

He also backed Williams driver Nico Rosberg's concerns that the new trend for twilight races in Asia is "very dangerous".
