Reports suggest he left the team because he was unsettled by the internal power struggle within Red Bull, following controversies involving team principal Christian Horner.
The team boss was accused of inappropriate behaviour towards a female employee, however Horner was cleared of any wrongdoing following an internal investigation.
Newey has already cemented his legacy in F1, designing title winning cars including the 1992 Williams-Renault FW14B, and most recently Max Verstappen’s 2023 RB19.
Since his announcement, Newey is rumoured to be in talks with Ferrari about a potential move to the Scuderia.
Ferrari have already signed Lewis Hamilton for 2025 and could add Newey for an iconic line-up.
The British driver has been complimentary of the engineer during the Miami Grand Prix race weekend.
"Adrian has got such a great history and track record. He's obviously done an amazing job through his career and engaging with teams and the knowledge he has. I think he would be an amazing addition," said Hamilton.
"He [Newey] would be a privilege to work with."
When asked how much he would like to see Newey join Ferrari, Hamilton added: "Very much."
Speaking to Martin Brundle on Sky Sports, Newey responded to Hamilton’s comments.
“Honestly, I mean it’s very kind of Lewis to say that, very flattered. But at the moment it’s just, take a little bit of a break and see what happens next.”
