Button determined to end Red Bull run

The Briton believes that it is just the low temperatures at the past two events that have held Brawn back, rather than any significant change in the balance of power.

Although he is not underestimating the challenge of Sebastian Vettel and Mark Webber this weekend, Button does not think the RBR pair will run away with the race as they have recently.

"I think both of them are going to be quick," he said. "If you look at past seasons they have been very quick around this circuit, both of them against their team-mates, they are driving a very competitive car.

"But they have us to contend with here, we're going to be pushing them a lot more here. It's going to be a bit cooler this weekend, but it's still going to be hot enough to make the tyres work.

"And we need to start beating them, otherwise they'll take too many points off us. They've already taken 11 points out of me in two races - that's too many."

He reckons the Brawn's kindness to its tyres - which has worked against it at the last two events where a more aggressive set-up has been required to generate temperature - will be an advantage in Hungary.

"I'm really looking forward to it - there's no excuses," said Button.

"It's supposed to be warm this weekend, so we should get the tyres to work. I think people are going to struggle with overheating on the super softs, so it's going to be about tyre management as usual. This year has been all about tyre management.

"We also have some updates that will move us forward a good chunk, they are mostly aerodynamic. You see what it says in the windtunnel, but you don't know whether it's going to be reality on the circuit. I'm happy with the step forwards and hopefully it'll be enough to challenge the Red Bulls and make it more exciting."
