Red Bull has put a stop to speculation about Ferrari’s interest in Adrian Newey by confirming that he will be with the company for the long haul.
Intriguingly he will get involved in some new projects, and it’s apparent that he will be taking a step back from his current F1 duties.
A statement said: “Red Bull is pleased to confirm that it has extended its successful relationship with Adrian Newey with a new multi-year agreement.
“As part of this new agreement, Adrian will work on new Red Bull Technology projects, as well as advising and mentoring Infiniti Red Bull Racing as it develops its Formula One cars over the next few seasons. The details of the new projects will be announced in due course.”

No wonder Red Bull were working to keep Dan Fallows, I suspect the knowledge that Adrian was leaving was know just after Fallows decided to go! Nice bit of horse trading.
