Nico Rosberg has vowed to avoid a repeat of the pain of Formula One world championship defeat to Mercedes team-mate Lewis Hamilton this season . A wheel has yet to turn in anger in the new season but the expectation already is that Mercedes will continue to dominate . It means the fight for the drivers ' crown is likely to be a further showdown between reigning champion Hamilton and his team-mate Rosberg . Nico Rosberg is determined to gain revenge on his Mercedes team-mate Lewis Hamilton and win the Formula One drivers ' championship in the 2015 season , which gets underway in Melbourne this weekend . Rosberg and Hamilton will once again have the strongest car on the grid this season . Last year Hamilton reeled in Rosberg 's early advantage with a run of six victories in the final seven races to clinch his second title . Rosberg , though , is determined to gain revenge as the 29-year-old German said : ' I have focused on pushing myself even harder for the rematch with Lewis . 'In the end , it comes down to who can put the best season together overall , and I have to make sure it 's the other way around this time . 'Having said that , my team-mate is one of many strong competitors I have to beat if I want to be world champion , so I 'm just focused on being the absolute best I can be . Rosberg tries out the new Mercedes car during Winter Testing at the Circuit de Catalunya last week . Rosberg sits in his car ahead of a test run in Barcelona at the end of last month . ' I now know the feeling of winning races and I intend to do a lot more of that , but I also know the feeling of not winning in the end and I do n't intend to repeat that experience . 'It 's a huge motivation for me and gives me even more determination for 2015 . ' Hamilton is equally fired up to write his name into F1 folklore and join a rare breed of three-times champions . 'There are many good drivers out there and all of them want to win - you just have to want it more than they do , ' said Hamilton . ' I feel fresh , I feel fit , I feel relaxed , I feel positive ... I feel ready . 'As a driver you get stronger with every season , so I plan to be better than last year . '
