LONDON, England - Lewis Hamilton, with his new Mercedes tenure having now officially begun, says he wants to turn the UK-based team into a Formula 1 front-runner.After six years with McLaren, Hamilton has joined Mercedes to replace Michael Schumacher.Hamilton said: "Doing better than Schumi? I don't look at it that way. He is a legend, unattainable. Looking to the future, I would be very happy if I can help Mercedes to compete with the top teams."PERSONALITY CLASHThe former McLaren driver and 2008 world champion has a roller coaster F1 career. He's acknowledged as among the very best, but often embroiled in personality scandals.Hamilton said: "Each of us has a personality, so you have to be yourself and ignore what people say. The important thing is to be consistent - sometimes you worry, sometimes you don't. What I'm looking for now is stability in my life."As for on-track exploits, Hamilton said: "The pass I like the most is Hakkinen on Schumacher at the end of the straight at Spa (in 2000) but I've also done some that I'm proud of."
