Button: 'We've yet to unlock MP4-29's potential'

Jenson Button is certain that the McLaren MP4-29 is a fast car, but he believes it will take a few races to unlock its full performance.

The Briton earlier admitted that McLaren weren't were they wanted to be, and whilst more recent comments suggest they're heading in the right direction, he still believes they need more time.

"While there's plenty of potential within MP4-29, we still think it'll take a little time to unlock that promise," he said.

"It's not quite where we'd like it to be, so I don’t think we go to Melbourne with a package that accurately reflects our progress with the car – it'll take a little longer for that to become apparent.

"In general, this season is going to be all about continuous development. Our stated aim has always been to try and scoop up a useful haul of points from the opening races – by virtue of solid engineering and good reliability – and then to quickly refine and develop the package, and deliver further performance in due course."

The car is however a clear step above last years challenger, which failed to score a single podium finish for the team.

"The MP4-29 has given us what last year's MP4-28 didn't – namely, a reliable and predictable platform upon which we can build and develop.

"In every respect, this year's car feels different to last year's, and that makes me excited – which is exactly as things should be as you head off for the first race of the year."
