Red Bull will continue to make use of Renault engines in 2016, according to a new report.
The Milton Keynes-based team have endured a rocky relationship with the French manufacturer of late, and earlier this year looked to end their partnership a season early.
At the time, Red Bull believed that they had a deal with Mercedes lined-up. However, the German outfit decided they did not want to supply their rivals, and potential partnerships with Ferrari, Honda, and VW have since come to nothing.
As a result, Red Bull are short of options, and according to Autosport, they are now looking to negotiate a deal to remain with Renault. However, a new agreement will cost Red Bull significantly more.
"Renault-affiliated sponsors Infiniti and Total will remain on the RB12 next year, but then disappear from 2017 onwards," the Autosport report read.
"Its deals with Infiniti and Total have given Red Bull more than double the amount in sponsorship than it has been paying for the Renault engine supply.
"Under the terms of any new agreement there will be significantly reduced funds from the two big sponsors for 2016, increasing what Red Bull itself must pay Renault.
"That additional revenue for Renault will, in part, help fund its works team revival, with its deal for a majority stake in Lotus set for completion around the Abu Dhabi Grand Prix later this month.
"It will also have more money to invest in its engine development programme as it chases Mercedes and Ferrari."
However, the deal will not go through without the approval of Red Bull owner Dietrich Mateschitz, and it is believed that the Austrian is yet to decide whether or not Red Bull will remain in the sport.
