Red Bull chief Helmut Marko has fired a warning to their Formula One rivals after switching engines to Honda.
“The figures make us really optimistic, also with regard to the increase in performance,” Marko told Motorsport.com.
“For the first time, we can also celebrate with a ‘party mode’! The Honda engine is already slightly above the Renault engine. If you combine our GPS data with the data provided by Honda, we’ll be in the Mercedes and Ferrari region.
“Of course they’re not sleeping either. But they are already at such a high level that they can no longer make such jumps. Even if we should be 10 or 15 kW behind, that was no different in our Renault era with the eight-cylinder engine. We can make up for that.”
