( CNN ) -- Mark Webber vowed to push Sebastian Vettel for the 2013 world title when their champion Red Bull team launched its new Formula One car on Sunday . The veteran Australian has had to play second fiddle to the all-conquering Vettel in the past three seasons , despite at stages being in contention for his maiden championship . He has had to contend with recent criticism from Red Bull 's motor sport advisor Helmut Marko , who claimed the 36-year-old ca n't cope with the title pressure . `` I do believe I can have a crack at the championship again this year , as I have done in previous seasons , '' Webber told reporters at the RB9 's launch at the team 's English headquarters in Milton Keynes . `` That is my goal and what I think about each day when I get up , and I 'm working hard with the team on doing that . `` They know I need 100 % support . You can not win a world title with only 90 , you need 100 , and we 're going into 2013 with this in place , and I 'm comfortable with that . '' Team boss Christian Horner , who signed a new multi-year contract last week , backed Webber to be a contender despite him finishing sixth overall last season -- 102 points behind his teammate . `` If we were n't happy with Mark then we would never have signed him to be with the team for this year , '' he said . `` We 're very happy with Mark and we give both drivers equal opportunity . It 's ultimately down to what they do on the circuit . `` For us , it does n't matter which driver wins , as long as it is a driver in one of our cars . Both of these guys believe they are the best , and the team will do the very best it can to support them . '' Vettel became the youngest driver to win three world titles as he overhauled Ferrari 's Fernando Alonso in the final third of the season . `` It all starts again from zero . We 've all got the same chances in what will be a tough year again with a lot of races , '' the 25-year-old German said . `` So I 'm just looking ahead . I 'm not looking back on past races because I am convinced it does n't give you a head start or an advantage . `` Obviously , the expectations are still there , but more than that we expect ourselves to do well again , so there is a lot of pressure . `` Right now there is excitement to get back into the car , start testing , then go racing and find out where we are . It 's one thing to do all the talking now , but as soon as you have the helmet on , you simply want to perform and do your best . ''
