Button: More to come from Brawn GP

The Briton led home team-mate Rubens Barrichello in a one-two for Ross Brawn's team on its debut, but highlighted areas for improvement such as his slow second pitstop.

"I am looking forward to getting back in the car and building it into something even more special, because we are not there yet," Button told AUTOSPORT. "It is not perfect and we didn't get the best out of it this weekend.

"I won the race, but our pitstops, I lost six seconds at the second pitstop. So we have a few areas we are weak in and that was always going to be the case because we haven't done any testing, so it has been very, very difficult for everyone to be perfect.

"There is room for improvement and that is what I am looking forward to achieving."

Button also expects a greater challenge from the likes of McLaren and Ferrari at Sepang and in the coming races and is eager to make the most of the opportunity his team has now.

"We don't know who is going to be quick there [Sepang] as it is such a different circuit. You would say we are going to be competitive, but it is a question of who else is going to be up there with us.

"I think people will start to make big leaps forward. I don't know if it is going to be at the fly away races, but when we get back to Barcelona people will have new aero packages and they will be on our arses.

"So we need to make the most of this and get the best out of everything, which we haven't quite done. But it is nice to have had not quite a perfect weekend and come away with a pole position and a win."
