Red Bull drivers Daniel Ricciardo and Daniil Kvyat insist they aren't worried about their futures with the pair confident the company will remain in F1.
The former world champions remain at the centre of paddock speculation heading into this weekend's Japanese GP in the wake of fresh threats to quit the sport from owner Dietrich Mateschitz and advisor Helmut Marko should they be unable to source a 'competitive' engine.
With the official break-up of their relationship with Renault thought to be imminent, Red Bull are in discussions with Ferrari over a supply of the Scuderia's power units for 2016 with Mercedes having already decided against bailing out their rivals.
A withdrawal by the Red Bull company would put the positions on the grid of their four F1 drivers - Red Bull's Ricciardo and Kvyat along with Toro Rosso's Max Verstappen and Carlos Sainz - in jeopardy for 2016, particularly as few comparable seats remain unfilled.
However, despite the increasing uncertainty, neither of the main Red Bull team's drivers are yet unduly worried.
"Right now I'm honestly not concerned. More curious to see what happens, really," Ricciardo said.
"It's still only September, the sooner we get an answer the better don't get me wrong, but we're not in November, December yet. When you start getting to that part of the year you've got to decide what's going to happen. It's still early. I'm confident we'll get what we're after."
Ricciardo said he had spoken to Marko and team boss Christian Horner on the matter, adding: "They are confident they will figure it out one way or another. Obviously it's in our interests to try and get the best - we want to win as well - so that's what we're trying to get.
"I have confidence in them. They are not promising anything, but I have confidence it'll figure itself out."
Mateschitz has made clear his intentions in recent weeks and Ricciardo, whose Red Bull deal is thought to run to 2018, added: "I'll let him do what it needs to and if it gets later in the year and still nothing's come I'll maybe make a little bit of noise, but honestly I don't think it will get to that."
Team-mate Kvyat insisted that focusing on on-track matters was a bigger priority for him at the moment "because worrying about the future right now will not help so much". The Russian agreed with Ricciardo that the situation would ultimately be resolved in a positive way.
"Red Bull have had a short time in Formula 1, but already have a strong history and very big achievements. Of course, my dream is to win for Red Bull Racing one day, so obviously of course I want them to stay. The team is made of fighters and we will fight to the end whatever happens," Kvyat added.
"I think it's all going to be fine in the end. It's just a matter of time to take the right decisions."
However, even if Red Bull do stay on the grid beyond the end of this season, Kvyat's own future at the team is not yet set in stone. Speaking at last week's Singapore GP, Horner said that while Ricciardo was on a "fixed-term contract", Red Bull had options on Kvyat, Sainz and Verstappen.
"We are talking about whether Red Bull stay or not, so let's wait before we talk about myself. At the moment I'm just doing my best race-by-race, then we'll see," Kvyat said when asked if his seat was secure. "We are awaiting until things are settled then we take the next decisions."
