Brawn GP still have plenty of room for improvement despite their one-two debut finish in Sunday's season-opening Australian Formula One Grand Prix, according to race winner Jenson Button.
"I'm looking forward to getting back in the car and building this car into something even more special because we're not there yet," the Briton told reporters after his pole to chequered flag win.
"It's not perfect and we didn't get the best out of it this weekend."
While rivals said the Mercedes-powered Brawn was in a league of its own at Albert Park, Button said the lack of pre-season testing was evident and the team's pitstops were also not as slick as they should have been.
"It's been very difficult for everyone to be perfect but there's room for improvement and that's what I'm looking forward to achieving," said the Briton, whose team secured their survival only this month after a management buyout of predecessors Honda.
The next race is in Malaysia on Sunday at the sweltering Sepang circuit where Button took his first podium finish with BAR in 2004 and which he lists as one of his favourites.
This time he will be returning as championship leader after two years of hard labour among the backmarkers with under-performing Honda.
"It's weird, it's surreal in a way because it feels so normal," he said of only the second win of his Formula One career. "And it always does, that's the thing.
"After winning in Hungary (in 2006) it felt normal. This is what I am here to do."
Button knew when he arrived in Melbourne that his car was something special and he proved that by leading all the way from pole position on Sunday. Now he had to put a lid on the excitement.
"You get so excited you find it difficult getting to sleep but hopefully that will pass. It's a nice problem to have," he said.
The championship, with 16 races still to come, remained a distant dream.
"I'm not interested in talking about it at the moment ... we need to think about getting the points on the board and then you see where you are later on in the season. You can think about changing the strategy then," he said.
"I'm not seeking to prove anything to anyone because I know I'm good and now I have a competitive car hopefully we can have a competitive season," he added.
"But I'm not thinking about 12 or 13 races down the line, there's no point in doing that. You need to concentrate on now and that's exactly what we are doing."
