Sébastien Ogier retained the Wales Rally GB lead from Estonian Ott Tänak on Sunday.
The Frenchman, who sealed his fourth consecutive world title in Spain earlier this month, completed the second and penultimate leg with a 33.8 sec advantage over Tänak. Thierry Neuville was third, a further minute adrift in a Hyundai i20.
Although conditions were better than yesterday, fog and greasy dirt roads in mid-Wales ensured driving was far from simple. But Ogier, who has led since the start in his Volkswagen Polo R, kept Estonian Tänak at bay during eight speed tests covering 99.91km.
Tänak won four of the first six special stages in his Ford Fiesta RS to cut the Frenchman's lead from 37.3sec to 24.8sec. But his hopes were dashed when Ogier regained a large chunk of time in the dank and muddy penultimate test at Aberhirnant.
"I tried to go flat out for the whole day, pushing hard all the time," said Ogier. "Tomorrow I'll do what I can and see if it is enough."
