Lewis Hamilton not ruling out McLaren return after Mercedes spell

Hamilton is leaving McLaren at the end of the year to race with rival Mercedes after six seasons with the Woking-based outfit.

His exit from McLaren puts an end to a relationship that began when he was racing in karting as a 10-year-old.

After one Formula 1 title and 21 grand prix wins, Hamilton said he needed a new challenge and accepted Mercedes's three-year deal offer.

The Briton admitted, however, that the prospect of returning to McLaren in the future is never out of question.

"You can never say never and I've had a great time," said Hamilton. "I think it will always be my home.

"I'll always look at it as where I've come from. Going back there would be nice one day. But I want to go and experience some things for a bit.

"It's almost like leaving home and going travelling for a bit. But I'm doing it with a different company."

Although Mercedes has endured a disappointing season - finishing in a distant fifth place in the constructors' championship - Hamilton insisted he has no regrets about his decision.

"No, I'm really, really happy about it. You can't live with regrets in your life," Hamilton added.

"You have to make a decision and stick with it. Whether it's right or wrong, you just have to make the most of it, stick to your guns and hope you can turn it around or turn it into a positive."

Hamilton, the 2008 world champion, will partner Nico Rosberg at Mercedes.
