With Red Bull set to take the next step and build its own power unit, Helmut Marko has made it clear they will solely be responsible for the engine.
The Milton Keynes outfit will continue to develop its Honda engines once the Japanese giants pull out of F1 at the end of the season. The operation will move to the next level after that as Red Bull will design their own power unit for 2025.
Mercedes boss Toto Wolff recently suggested that Red Bull's strategy could see them link up with Volkswagen, but Marko was quick to shoot down those suggestions.
"He made a very indelicate statement that we would get the patent rights from Honda and pass them on to VW," Marko told F1-Insider.com. "That is complete nonsense, that would be unfair and it is not planned.
"As long as the current regulations apply, we are solely responsible for this engine."
Reflecting on how far Red Bull have come over the years, Marko revealed the team only ever planned on winning a race or two when it first got off the ground, but they have continued to dream big since then.
"It's an incredible story," Marko stated. "We took over the Jaguar team 15 years ago. The goal was to win one or two races. We never dreamed that we would become world champions four times. With Honda's withdrawal, the question arose: what do we do now? Becoming a Ferrari or Renault customer team doesn't sound that attractive, and it's not.
"You always get second choice and when you build the chassis you are dependent on what you get from the engine manufacturer. Now we have everything in one house, so we have a situation like Ferrari, where chassis and engine development are combined on the same site. It's an almost unimaginable dream come true. We are also very grateful to our owners, because this also requires financial commitment.
"But we are right on schedule. In the first step, we will build and use the Honda engines from 2022 to 2024. And when the new regulations come in 2025 - where it is agreed that the costs have to be drastically reduced, which will also involve many standardised parts - that means that it should be possible to design such an engine even for a not absolute engine specialist with experience."
