The Brit had previously designed championship-winning cars for F1 legends Sebastian Vettel and Max Verstappen, and was involved in delivering a total of 13 world titles during his time there.
And before he gets started in his new role, Newey has been granted access to the team's impressive new facilities as they continue to lay the groundwork for what they hope will be a long and successful era in F1.
Development of the first phase of the Aston Martin Aramco Cognizant Formula 1 Team Technology Campus concluded in 2023, and now the second phase has also been completed.
The AMR Technology Campus will be the home to manufacturing within a single location for the first time in the history of the team's operations at Silverstone.
Speaking to media at a press conference, team owner Lawrence Stroll revealed that staff have now moved into the facility, and that Newey had a tour booked in.
Sitting alongside Stroll, Newey said: “These facilities are just stunning.
“It’s not an easy thing to do, to build a brand new factory on a greenfield site and have a warm and creative feel to it.
“I’ve seen some buildings that haven’t fulfilled it, but these have. I am so looking forward to starting and getting to know everyone here.”
