World champion Sebastien Loeb will take a 36-second lead into the final day of the Rally Mexico after extending his advantage on Saturday.
Finn Mikko Hirvonen was in second spot and closest challenger to the 38-year-old Frenchman as the Citroen team comfortably maintained the top two places through Saturday's final three stages.
Loeb, hoping to clinch his sixth straight victory in Leon, told www.wrc.com: "Now we have a good and comfortable situation but there is still a long way to go and a 54-kilometre stage so still nothing is done.
"It's a rally where I have had a lot of success and I hope that continues tomorrow."
Hirvonen's compatriot Jari-Matti Latvala (Ford) was fastest on both runs through the Comanjilla stage but remained more than two minutes behind Loeb after problems earlier in the weekend.
Petter Solberg (Ford) overcame brake issues on Saturday morning to finish day two in fourth place ahead of fellow Norwegian Mads Ostberg (Adapta Ford), with Estonia's Ott Tanak (M-Sport Ford) sixth.
