Citroen's Kris Meeke mastered the final two legs of Rally Spain to win by 28 seconds, just three rounds after his form sank to such a low that he was dropped from the team.
Four-time defending world champion Sebastien Ogier fended off teammate Ott Tänak to claim second by 5 seconds. Title rival Thierry Neuville retired on the final day with broken suspension and Ogier can secure the crown at the penultimate round in Britain later this month.
Their M-Sport World Rally Team moved within touching distance of a first manufacturers' title since 2007. The Ford Fiesta pair need only finish in Britain, irrespective of their overall placings, to take the championship.
Meeke's strong pace on the opening leg's gravel roads laid the platform for victory. He swept into the lead yesterday morning when the surface switched to smooth asphalt, and rounded off a dominant display by winning five of today's six speed tests.
"It's not so important how many times you're knocked down, it's more important how many times you stand up again," said Meeke, as he celebrated with wife Danielle and two young daughters.
