Ross Brawn admits he has been "very impressed" with Jenson Button's driving in the first two grands prix of the 2009 season.
The British driver scored an emphatic win from pole position at the Australian Grand Prix last Sunday, and kept his momentum going today by securing his fourth career pole in Malaysia.
Button endured a dismal 2008 season with Honda Racing, scoring just three points, but things have look much brighter in the team's new incarnation.
Brawn says Button has been revitalized this year.
"Very," said Brawn when asked how impressed he was with Button. "I don't think last year with the equipment he had... I commented a few times, I saw some good races, I saw some races that were not great.
"You know him, you can see he is reveling in it and he is driving very well. He is such a smooth driver it is incredible."
He added: "To some degree now that he has got a car to work with. He is working very diligently with the engineers and he has been kind of revitalized and that is understandable, if you have got some equipment you can use. So I think both sides will come.
"I think the car is hopefully going to get better over the next few months and he is going to naturally improve because he is hugely talented and two years of beating your head against the wall takes it out of anyone.
"I think we are very impressed today, he never put a wheel wrong. His times on the prime tires in the middle of qualifying were just stunning."
Button, who was linked with the Ferrari team when Brawn was there, reckons going to the Italian squad may had been an error.
"That might have been a mistake. It's just so difficult to judge people," he added. "I mean, Jenson is a pretty low profile guy in many ways. He doesn't bang his own drum and he gets on with things discreetly and quietly.
"It's a bit like his driving style, very smooth and very controlled so. I am very happy."
