Hamilton expects to be 'a lot stronger'

The British driver only lost the drivers' title to Kimi Raikkonen in the final race of the year, but scored just one less point than the Finn after winning four races in a record-breaking season.

Hamilton, whose team unveiled their new MP4-23 car on Monday, said both McLaren and him will be stronger after last year.

"It gives me great pleasure to be here today on my birthday," said Hamilton, turning 23 today. "After such a great season in 2007 I think the approach will be very, very similar to last year.

"We have a better car, a new teammate and as a team are stronger and as a driver I have developed so much over one season that I will be a lot stronger next season than last year.

"So with the same mentality, approach and determination we can do well."

Hamilton will be partnered by Finn Heikki Kovalainen, who has joined McLaren after making his Grand Prix debut with Renault in 2007.

Kovalainen admits he has already been impressed with McLaren, and is hopeful he will enjoy a strong season with his new team.

"Of course for me it is a fantastic opportunity," said the Finn. "It is a big step forward in my career to join McLaren. So far I have been impressed with what I have seen at the factory in Woking, meeting engineers, meeting people.

"Everyone is determined to return to the top and I will do the maximum I can before the first race, to start the season well in Melbourne and hopefully have some good results."
