Formula One's five title contenders have lined up together at South Korea's new circuit and agreed that the championship is still wide open.
Australian Mark Webber leads Ferrari's Fernando Alonso and his own Red Bull team-mate Sebastian Vettel by 14 points with three races remaining, including Sunday's inaugural Grand Prix at the new Yeongam circuit.
McLaren's Lewis Hamilton is a further 14 points back, with team mate and reigning champion Jenson Button fifth and three more adrift.
Webber says he won't back out from a challenge on the circuit even from his team-mate Vettel.
Weber and Vettel have come together on the track already this season.
