However, these claims have since been rubbished by Newey and his manager Eddie Jordan, with his expertise still up for grabs from rival F1 teams.
Newey has been linked with just-about every team on the F1 grid since he announced he would be leaving the Red Bull, however a new favourite has emerged in recent weeks.
Newey has previously worked with Aston Martin on the design of their hybrid sports car when they partnered Red Bull - the Aston Martin Valkyrie.
This week however, Newey turned his attention to his final Red Bull project that will debut at this year’s Goodwood Festival of Speed - the RB17 hypercar.
Only 50 units have been slated for production of the rare design, which features a V10 engine, advanced ground effects and an engine recovery system.
The RB17 is track only meaning owners will be invited to on-track training and simulator experiences as part of the £5 million price tag.
The engineer featured in a video on Red Bull's Instagram, where he lauded the ‘sensational’ project.
"RB17 really is pushing the boundaries of everything I've learned over my career into one car,” Newey said.
"I'd love for it to be viewed as a sensational piece of moving art that is something that has not ever been done before, in terms of its sheer performance, beauty, sound and enjoyment of ownership."
