Helmut Marko has claimed that Red Bull are 'miles ahead' of their Formula 1 rivals when it comes to their engine development, in part due to the team's aggressive recruitment strategy.
As of 2026, Red Bull, alongside all other F1 teams, will be hit with a string of new regulations.
The change in rules will see the MGU-K produce three times the electric power that it currently does; each car will also use 30kg less fuel; and no new carbon from fossil fuels will be released into the atmosphere.
Yet Marko has now hit back at these claims, insisting that they are on track, in part thanks to poaching some key members of staff from Mercedes and Ferrari.
Marko: Red Bull miles ahead of F1 rivals
"I don't think we're technically behind," he told Motorsport-Total.com. "We got people from Ferrari, Mercedes, Renault and Cosworth [for the engine department].
"We have Ford as a partner in the sector. We have absolute top people when it comes to combustion engines. And we have two very bright minds on the electric side."
Marko also emphasised that Red Bull's new engine factory in Milton Keynes is 'state of the art', going on to insist that the team are clear of teams such as Ferrari and future F1 rivals, Audi.
"In August, we are still running a complete combustion engine with MGU-K and battery," he added. "There we are miles ahead of Audi, we are miles ahead of Ferrari, and Mercedes is about the same."
