Red Bull Racing will decide later today if it runs its KERS during the Malaysian Grand Prix weekend.
The team decided against using it during the Australian Grand Prix, as it believed the reliability risks were not worth it considering the advantage it offered in Melbourne. However, the nature of the Sepang circuit makes the device much more crucial and Red Bull had admitted it was a "must" for the weekend.
Team boss Christian Horner said after practice that the units had worked without problems, and that a decision on whether to use it all weekend would be taken before tomorrow's qualifying.
"In Australia we ran the system on the Friday, we felt there was a potential reliability risk and the benefit of KERS in Oz was arguably less than other venues," said Horner. "We decided not to take that risk and removed the system from both cars on Friday evening with a view to running system
"The system has run well and reliably here, so a decision will be made later this evening."
