Sebastian Vettel ready to hammer rivals

London: Formula One racing driver, Sebastian Vettel is ready to hammer his rivals yet again after spending the winter relaxing at home.

The triple world champion, who re-emerged in public on Sunday to launch Red Bull`s new RB9 car, said he had been fortunate to stay at home, especially after a tough end to last season, which drained his energy.

The 25-year-old German will start the new season as big favourite to make it four championships in a row.

Vettel, who has 26 race victories, 36 pole positions and three world titles to his name, said it will be a tough year again with a lot of races.

He said that soon as he has the helmet on, he simply wants to perform and give his best.
