Despite the soaring temperatures in Hungary and the notoriously tight and twisty Hungaroring combining to make overtaking a difficult prospect in this weekend's Grand Prix, Jenson Button suggested that there could be some surprised in store once the lights go out.

"It's going to be pretty intense, which is good," said the driver. "It's not the easiest circuit to overtake on, but I have a feeling if we have a 56 degree [track] temperature it's not going to be a straight forward race.

"I think we'll see some overtaking," he insisted, and pointed to Saturday afternoon's support race for evidence of how things might turn out. "Looking at the GP2 race - which is probably the best GP2 race I've ever seen - we're in for a treat," he said.

Asked if this was shaping up to the the hottest race that he'd ever competed in, Button suggested that a recent outing in Bahrain might have exceeded even the 40C (104F) air temperatures expected on Sunday afternoon in Budapest.

"Bahrain as pretty hot a few years ago, but I think the different between them is that you've got time to breath down the straight [in Bahrain] whereas here it's going to be pretty intense!" he said.

"It'll be a very interesting race, similar to Bahrain," agreed Button's team mate Sergio Perez. "It'll be a very tricky race to get the maximum out of it."

Notoriously the McLaren pain clashed on track at this year's Bahrain event, something that Jenson Button couldn't resist reminding his young team mate about.

"It'll be great fun. It'll be nice to keep all the bits on the car this time though. We'll give that a go, yeah?" he asked Perez, to laugher from the assembled journalists.

Overall Button said that despite missing out on Q3 this weekend, which leaves him in 13th place on the grid for the start of the Hungarian Grand Prix, the disappointment of a poor starting position doesn't affect his energy and enthusiasm once he gets into the car.

"For us, when we get into the car you just want to do the best job you can," he insisted. "When you're sat on the start line ... you still get excited about the race and looking forward to moving forward and want to do the best job you can. So nothing changes when you're racing, and it shouldn't."

Instead, Button suggested that it was outside the car when facing the media that was the trickiest part of his working day.

"I think the most difficult part of the weekend for us, when the car isn't so strong, is after the qualifying and after race and talking to you guys," he said, indicating the reporters. "You obviously bombard us with questions which is your job, about why we're not where you expect McLaren to be.

"That's probably the toughest part of the weekend,' he added.
