STUTTGART, Germany (AFP) - Lewis Hamilton said Saturday the tension with his Mercedes team-mate Nico Rosberg has disappeared, a week after the Briton won the world drivers' championship ahead of his German rival.

Hamilton's victory at Abu Dhabi in last Sunday's season finale saw him crowned world champion for the second time as he finished 67 points ahead of Rosberg after their battle for the 2014 title went to the wire.

The pair appeared at Mercedes' end of season party in Stuttgart in front of 50,000 fans with Hamilton saying all the friction between the pair during the season is now long gone.

"All the tension disappears and we have gone back to being two normal individuals, talking about the normal things guys talk about," said Hamilton when asked about relations with his team-mate.

Rosberg, who resumed testing on Tuesday, is already looking ahead to the 2015 season.

"I didn't reach my big goal, but there was a lot of positive things to take from the season and things I can perhaps do differently. I will focus on 2015," said the German.

Hamilton's contract expires at the end of next season and the Briton was relaxed about extension talks.

"I feel at home here and I also still have a contract until 2015, so there is no rush," he said with Rosberg under contract at Mercedes until 2017.

"I hope we can sit down and talk about it before Christmas."
