Horner is clearly unhappy with the reliability of the Renault power unit. “It’s frustrating that we’re in the situation that we are,” he said, speaking to Autosport.
“We’ve won all the races and all the championships that we’ve achieved with Renault power. But the situation just isn’t improving at the moment.
“The reliability is unacceptable. The performance is unacceptable. There needs to be change at Renault. It can’t continue like this. It’s not good for Renault and it’s not good for Red Bull.
“We need to work together as partners. There will not be another engine in the back of the car next year, but we want to be competitive and we want to run at the front.”
For their part, Renault isn’t shying away from its responsibilities.
“The anxiety that Christian feels, and the frustration he feels after a result that is not at the full potential of the performance of car and power unit, is completely understandable and shared by us,” acknowledged Renault deputy managing director Rob White.
“But we are completely committed to making progress as fast as we possibly can and I think we have shown signs of progress before now. This is a process that is completely shared with Red Bull, and the objectives are known and understood.”
