The Milton Keynes based outfit has been powered by the French company since 2007, having used Cosworth and Ferrari engines in 2005 and 2006.
After winning the last four constructors’ titles with Renault, Red Bull’s 2014 season started poorly with frequent reliability issues related to the new 1.6 litre V6 Turbo power-units in winter testing.
Despite having the second fastest car on the grid, the team has struggled on the straights and lost points due to retirements caused by engine problem.
According to Christian Horner, Red Bull’s relationship with Renault is reaching a pressure point.
“We will have a look at where the engine is standing after this weekend and then we will see what we can achieve with this engine,” Red Bull advisor Marko told Sky Sports.
“If we don’t see a possibility to be on a same level with Mercedes then we will have to look for alternatives. We will not be asking Mercedes. But there are a lot of very skilled companies concerning engines. AVL is 70 kilometres from here.”
When asked if Red Bull could build its own bespoke power-unit, he replied: “You should never say no. We are looking at all alternatives.”
Horner confirmed that the team’s 2015 car will be powered by Renault next season. “They are having a tough time at the moment and we are doing our best to try and support them and assist them engineer their way out of this,” he said.
“But a team like Red Bull is never going to be short of options and it is our job and our responsibility and duty to look at all of those options to try and ensure we have the best power-unit going forward. Hopefully that will be with Renault but you have to look at all the options.
“We are approaching a pressure point, but we won’t have any other engine than a Renault in the car next year that is 100% certain. But we cannot afford to be in this position forever and Renault are doing their best to respond, but they need to make a step to close in on Mercedes.”
