Red Bull's technical director Pierre Wache has claimed that the team cannot replace Adrian Newey as they prepare for their title defence during the 2024 Formula 1 season.
Newey's near-18-year stay with Red Bull has seen him guide the team to six constructors' championships and seven drivers' titles.
Of course Max Verstappen has played a pivotal role behind the wheel, but Red Bull have been in a league of their own when it comes to car design in recent years.
And although Wache has admitted that Newey is not responsible for the entire concept of the car, the Frenchman did concede that there will be nobody who could step into Newey's shoes were he to leave.
"On a daily basis, he’s not part of our process. He’s more coming from the sideways and trying to help us or challenge us on different aspects of the team – it could be mechanical design, aero or vehicle dynamics."
"You have to use him as experience, as he has less time for us," he added.
"He’s more… I don’t know the word in English – when you say somebody is there to challenge one aspect of stuff. He’s not there to do the plan, to do the full concept of the car."
