Germany – Nico Rosberg has admitted he could return to Formula 1 as a team boss some day.
The new reigning world champion shocked the world by retiring just days after winning the 2016 title, but was back for a visit to the Barcelona test paddock recently.
But he told Germany's Sport Bild: "A comeback as a driver is impossible."
That doesn't mean he won't have mixed emotions when the five lights go out on the Melbourne gantry next weekend.
Rosberg said: "There will certainly be some strange moments when I see the first race on TV. I am still a huge fan of F1."
But he is not looking to fill his calendar any time soon.
He added: "I am looking for new projects and I have to say I'm really relaxed. 20 races a year is like being on a hamster wheel. I would also say that it's the best hamster wheel in the world!
"I am a passionate competitor and I enjoyed my career very much. But F1 is not a pony yard. To beat everyone and be world champion you have to be absolutely uncompromising and my goal was everything."
But Rosberg is not ruling out a return in another capacity one day, for instance as a team boss.
Speaking on opportunities within motor sport Rosberg noted: "I'm not saying no. A lot is possible. But at the moment, I am mostly concerned with social projects. Children and less privileged people – that means a lot to me.
"One would be helping other drivers on their way to success in an advisory and managing role. I've achieved everything I wanted. My new life is now an equally great challenge that I want to master just as successfully."
