Mark Webber says he is looking forward to proving himself again in 2012 after his difficult '11 Formula 1 season.
The Australian only won one race last year as his Red Bull Racing team-mate Sebastian Vettel swept to a dominant championship triumph.
Webber acknowledged that Vettel's form during his title-winning seasons had set a tough benchmark, but said he was raring to get the season underway and show that 2011 was just a blip.
"Many sportsmen or women, when you don't get the most out of a situation, you always want to come back and improve and do a better job," said Webber in a video interview as part of the launch of Red Bull's new RB8.
"The bar has been lifted very, very high in the last few seasons and it's the challenge I'm looking forward to.
"I've had a really good winter and prepared for the season as best I can so I'm looking forward to the new season, I just cannot wait to get racing. We can talk a lot about it but we need to get on the track."
Webber added that he did not feel his 2011 campaign had been as disappointing as it had been portrayed.
"As you say last year wasn't an amazing season, but it wasn't too bad for me," he argued. "I still managed to finish third in the drivers' championship, not far off second with Jenson [Button] there, so it was a great way for me to finish the year with the victory in Brazil and many strong results.
"We're always learning as athletes and I'm looking forward to 2012, it's got some great opportunities for me.
"You know the old cliche take each race as it comes but that's how it will be initially and we'll go from there."
