Frenchman Sebastien Ogier clinched the world rally championship title after Belgium's Thierry Neuville failed to win the first special stage of the Rally France on Thursday.
Ogier started the rally with an 83-point lead over Neuville in the standings and can no longer be caught by Neuville, who needed maximum points from the three remaining races and power stages on each rally.
"I'm so happy. Before the stage I was a bit confused about whether it would happen, but we're here and we managed to do it," said Ogier, who drives for Volkswagen. "Now I will be able to be aggressive all weekend because we've achieved our goal."
Points are awarded for Thursday's power stage and Neuville's second-place finish means he can no longer score maximum points. But Ogier pledged not to ease up.
"We now will focus on the rest of the weekend," he said. "What's important for us is the team title. I will do everything I can to get points."
