Ferrari initially emerged as the favourites to acquire his expertise, after reports suggested that he had already signed a deal with the Scuderia.
However, these reports have since been rubbished by Newey’s camp, offering little insight into his F1 future.
Where will Adrian Newey end up in F1?
Aston Martin have also joined the race to try and tempt Newey to their team, with the Silverstone-based outfit taking him on a private tour around their factory.
The 65-year-old has previously worked with Aston Martin on their hypercar project, where he developed the Valkyrie during Red Bull’s partnership with the team.
Whilst Newey has designed championship winning cars, he also has an appreciation for motorsport engineering history, revealing his top picks in a recent interview with F1.com.
The Lotus name featured in his choices, with Newey being the proud owner of the Lotus 49B which he drove around the streets of Monte Carlo at the Monaco Historique earlier this year.
Amongst his deliberations one historic motorsport name was excluded, with Ferrari failing to enter the discussions of the former Red Bull chief.
