Sebastian Vettel insists that the time to reflect on his dramatic F1 title success last year is now over as the German prepares to kick-start the defence of his crown next weekend in Australia.

The Red Bull driver became the youngest title winner in F1 history when his victory in the 2010 season finale in Abu Dhabi was enough to beat Fernando Alonso the crown.

Going into the new season, Vettel is viewed by many as the hot favourite to defend his crown after a strong pre-season from Red Bull's new RB7 and he insisted that there was no time to think about his previous success as he turns all his focus towards securing back-to-back titles.

"We know what it feels like to start the season in Australia, it's a special place with a special track," he said ahead of the race at Albert Park. "It's one of the few cities that lives Formula 1 for the week, so I'm looking forward to it. It has been an exciting winter and the time around Christmas was important to calm down, but since February we have been back in the rhythm.

"It's nice to look back at last year and at what we achieved but we're all looking forward now and focusing on the new car and season. It all starts from zero again; we're excited, we've had enough of testing now and we want to go racing again."
