Friday witnessed a great fight between Ott Tänak, who drove a Yaris, and Mads Østberg, who drove a C3. After rally leader changed several times, the Estonian ended the day with a 5.8-second lead. Local Finn Jari-Matti Latvala completed the day in third, with Hayden Paddon led Hyundai in fourth position after Teemu Suninen fell back in the final stage of the day with brake issues in his Fiesta. Title contender Sébastien Ogier, who was second on the road, climbed up to sixth overall after Ford gave his teammate Elfyn Evans a team order, which ordered him to slow down in SS10 before reaching the finish line. Defending rally winner Esapekka Lappi, who stalled his car at the opening stage of the day, cleared the day in eighth place, while Craig Breen, who suffered an early puncture and a late fuel pressure issue, completed the day in ninth. Championship leader Thierry Neuville, who struggled for grip all the day due to being first on the road, completed the leaderboard. Teammate Andreas Mikkelsen finished down the order after rolling his i20.
