But according to Autosport he is now being targeted by ambitious Aston Martin boss and team owner Lawrence Stroll in an attempt to turn his current upper midfield team into championship contenders.
The report from the outlet reports that a 'big-money contract offer' was made over the Saudi Arabian Grand Prix weekend to Newey who has long been considered as one of the greatest Formula 1 engineers of all time having also been pivotal to designing championship winning cars with McLaren and Williams in the 1990s.
Ambitious Aston Martin aiming high
Aston Martin have been making key moves in recent years in a bid to start challenging for titles having previously taken over the mid-field Racing Point outfit.
In addition to star driver Fernando Alonso the team have also attracted key designers from other F1 rivals and have also built a new state-of-the-art headquarters which the team moved into last season.
Having also bagged a Honda works deal for 2026, Newey could be the last major factor to land in terms of building a championship challenge.
Despite the offer, Newey only signed a new deal at Red Bull last year - insisting he wasn't planning on leaving the team.
However, it appears given the recent behind the scenes instability involving team boss Christian Horner and key personnel, Stroll has looked to move in to change his mind. Autosport added that Aston Martin declined to comment on the alleged approach.
