Lewis Hamilton has said that he is confident that he can outperform McLaren teammate Jenson Button in this year's world championship.
The British duo both won three races in 2011 but Button finished above Hamilton because of his more consistent performances throughout the season.
Asked whether he was at all concerned with the apparent shift in power within the team, Hamilton said: "No, I don't have any concerns with it. Considering last year, from my own personal feeling, that I wasn't performing at my best and I was still ... when you look at the qualifying positions my performances were pretty good.
"And I don't even feel that when I was qualifying, even when I got pole, that I was extracting 100 per cent of what I can do. And in races even less than that."
The 2008 world champion is hoping for a much more settled 2012 after "juggling" many issues off the track in the last campaign.
"At times less than 90 per cent of me was there," he added. "I was juggling too many things. Too many things I'd started weren't finished.
"Too many questions weren't answered or I hadn't clarified, or fixed, or figured out; whether they were personal things, purchases, investments, lawyers etc.
"But I've corrected things I've done wrong."
McLaren recently launched their new MP4-27 car for the new season which begins in Melbourne on March 18.
