Horner also aimed a dig at Wolff personally, suggesting Mercedes are ‘controlling’, and he believes the fact Red Bull are challenging with such established motorsport names is ruffling feathers.
“They are a very controlling group. That is Toto’s mantra. Suddenly, we are playing in their back yard with the engine too,” Horner concluded.
“How can an energy drinks company build a chassis that takes on and beats Mercedes, Ferrari, Renault, McLaren? It sits very uncomfortably.
“Now that we are taking on the power unit and attracting some of the best talent in the business, that is even worse. How can Red Bull produce a competitive engine? That’s our target.”
