Hagfors - Jari-Matti Latvala of Finland stretched his lead over compatriot Mikko Hirvonen to 23 seconds on Saturday, the second day of the Rally Sweden.
The pair had traded the lead during the opening day, but Latvala remained in front throughout on day two, topping four of the day's eight stages.
Norwegian Petter Solberg remains third, 51.4 seconds behind Latvala, with his countryman Mads Ostberg fourth, one minute, 2.5 seconds behind.
Eight-time world champion Sebastien Loeb, who lost two minutes on Friday after driving off the road, endured further misery with a spin and a puncture.
