Thierry Neuville leads the World Rally Championship's Tour of Corsica on Saturday evening after Sebastien Ogier's charge was brought to an end by hydraulic problems.
On the first stage of the afternoon, M-Sport Ford Fiesta driver Ogier took six seconds out of Hyundai's Neuville in the battle for the lead.
However on the next stage, SS8, Ogier had trouble with gearshifts and his car was rear-wheel-drive only, leaving the Frenchman to do his best not to lose too much time.
Neuville went quickest of all while his rival suffered, extending his lead to 38.9s with two stages to go.
He had taken the lead on the last stage of Saturday morning, when he claimed second from Ogier and Citroen's Kris Meeke retired from the lead with an engine problem.
His Hyundai team-mate Dani Sordo sits third, 18.8s behind Ogier. Sordo said he'd pushed to the "maximum" on SS8, but still sits just under a minute behind his team-mate.
Jari-Matti Latvala showed newfound pace in his Toyota and still remains within striking distance of Sordo, 11.7s behind.
A change to the rear diff meant the Finn was much more comfortable with the Yaris in the afternoon.
Not for the first time this season, Craig Breen is the highest-placed Citroen with his two team-mates having retired.
The Irishman didn't take any risks and continues to get seat time in the 2017 car after missing the previous round, and is only 2.8s behind Latvala at the end of the day.
Hayden Paddon is the last WRC car in the gaggle of leaders. Paddon was happier with his car in the afternoon loop, but lies half-a-minute behind Breen.
Andreas Mikkelsen leads WRC2 by over a minute in his Skoda Fabia R5, with M-Sport Fiesta R5 driver Teemu Suninen in the order.
Citroen's Stephane Lefebvre and DMACK's Elfyn Evans both crashed out of contention on Saturday morning.
