Hamilton has also been at pains to calm fears that the title may be slipping away from him, with Ferrari's Brazilian Felipe Massa now 10 points clear coming up to the halfway point of the season.
"Kimi [Raikkonen] was 17 points behind with two races to go last year," Hamilton said on the McLaren web site of the Ferrari driver who beat him to the title by a single point last season.

"The fact that he not only came back but also won the title tells you a lot about how unpredictable this sport can be. You can never take anything for granted.
"And that's why I'm still confident and focused," added the Briton, who slipped to fourth overall after leading the championship with victory in Australia in March and again in May when he won in Monaco.
"We've got 10 races remaining. 100 points -- it's all to play for and I'm ready for it."
