(CNN) -- Lewis Hamilton says team spirit has helped McLaren dominate the 2010 Formula One season as it reaches its halfway stage.
After nine rounds, the 25-year-old currently leads the drivers' standings ahead of McLaren teammate Jenson Button, who trails by six points going into this weekend's British Grand Prix at Silverstone.
They are closely followed by the Red Bulls of Sebastian Vettel and Mark Webber, who are third and fourth.
McLaren also top the constructors' championship ahead of arch-rivals Red Bull by 30 points.
The two McLaren drivers have one of the best relationships in Formula One and this has led to success on the track, Hamilton told CNN.
"Naturally, in any team you need to have harmony within the whole group," he said.
"There's no denying both of us want to win and only one of us can win.
"We both want to beat each other but the respect is there, the foundation of understanding where we've come from is there.
"For a team to be perfect you have to have everyone working in harmony."
Many thought the British team made a mistake by appointing reigning world champion Button to race alongside rival and fellow Brit Hamilton going into the 2010 campaign.
But the 30-year-old Button said he now "feels very at home" after joining from Brawn GP.
"It's always a tough change," Button told CNN. "I was with my previous team for seven years.
"So, to come to a new team after winning the championship initially I thought was going to be a real challenge and you're never quite sure what to expect.
"But as soon as I arrived at the factory everyone was really friendly and really welcomed me in. I feel very at home.
"I've been with the team for six months now and lying second in the championship just behind my teammate, so it's all going pretty well for us."
Button, whose only victory so far this season was at the Chinese GP, is looking to win his first race on home soil on Sunday.
A win would also see him leapfrog Hamilton in this year's title race.
"Lewis won the (British) Grand Prix two years ago when he won the championship," he said.
"I have yet to win the British GP or even get on the podium so it's a big race for me."
McLaren have already secured three one-two finishes this season and another at Silverstone would be the second British one-two at the British GP in the last 45 years.
The other occasion was when Scotland's David Coulthard beat Eddie Irvine of Ireland in 1999.
