Daniel Ricciardo has reported that Red Bull are close to announcing their 2016 engine partner and that it could happen as early as next week.
Red Bull are currently without a confirmed engine supplier for next year's championship after deciding to drop Renault.
But with Mercedes saying no and Ferrari only offering year-old power units, Red Bull's engine crisis has dominated headlines of late.
Ricciardo, though, says an announcement could be made in the coming week.
"I'm guessing, but I would say around Abu Dhabi," he told GPUpdate.net.
"There should be some news by the last race of the year. I won't promise anything, but hopefully in the next week you guys [the media] will know something."
He added: "Obviously it was dragging on a bit, but now that the team's confirmed that it will be on the grid, I know that I've got a job for next year, so that's already a good thing.
"Quite a few suppliers have turned us down, which is a bit of a shame. But you see their reasons; I think we've got a pretty good chassis, so they're a little bit scared, or whatever.
"We'll take what we can for now and see what happens for 2016."
