Red Bull Racing head Christian Horner admitted that the head of the technology department, Adrian Newey, now spends about 50% of his time with the team and spends the rest on other company projects, but is always ready to help if needed necessary arises.
Christian Horner « In recent years, Adrian has moved away from the daily work in Formula 1, now he divides his time between the team and Red Bull Advanced Technologies, where he is involved in various projects. But I believe our team now has the strongest engineering department in history, ever allowing him to take on the Valkyrie project.
Of course we still work with him, but not every day. I think he now spends about 50% of his time on Formula 1. He is in the office a few days a week. But if you need his help, the technical team can always call him.”
