Jenson Button says he already has a keen eye on 2017 and the prospect of new regulations being introduced to Formula 1, even if he insists it doesn't mean he will necessarily be racing.

The 2009 world champion ended weeks of retirement speculation at the start of this month by confirming he will stay with McLaren-Honda for the 2016 F1 season, at the time revealing the prospect of a step forward from the team had enticed him to remain.

However, though Button is confident the 2016 season will be stronger for the beleaguered Woking-based team, it is the changes being proposed for the sport overall from 2017 that has particularly piqued his interest.

With an emphasis on making the cars of F1 2017 faster and more aggressive looking, Button says he is excited by what is on the drawing board, even if he stops short of saying he will necessarily be there to experience it.

"The future of the sport is a lot more exciting than we thought it was maybe a year ago, with people understanding things need to change. There's been a lot of criticism about the sport in general and it's nice to see people are taking notice and things are changing.

"I don't know if I will be racing in '17, '18, whatever, but I think it looks very exciting and I think that's something the sport should be excited about, and the fans also.

In the meantime, Button remains focused on bringing McLaren up to speed in a year that has seen it struggle to mount a competitive bid with its under-powered and unreliable Honda power unit.

"Obviously we are focusing on now, the future is something we can look forward to, concentrating on now is the only way we are going to be competitive now. There are lots of changes within the team and the power unit. This is still a very young partnership and I think you'll see a much more competitive team next year."
