Lewis Hamilton is determined to have some fun at the end of his days with McLaren before tackling what he believes will be a tough debut campaign with Mercedes.

Hamilton's slender hopes of winning this year's F1 drivers' title ended in India last Sunday with a fourth-placed finish behind a dominant Sebastian Vettel, who has now won four consecutive races.

The Englishman, who trails Vettel by 75 points with 75 remaining, revealed: "I said before India the championship was out of the question, so now it's about trying to have the most fun and having as strong a race as possible.

"It's going to be tough next season because the current car they (Mercedes) have is not as great as the one I have now," said the 27-year-old.

"But with a lot of hard work, perhaps a new direction, maybe we can change it around."
