The Norwegian inherited the top spot when Oliver Solberg retired on Friday and delivered a lead management masterclass to maintain the distance between himself and fellow Škoda Fabia RS Rally2 driver Sami Pajari.
Mikkelsen, who is yet to finish outside of the podium in his two starts so far this season, did not claim a single stage win yet did more than enough to head Pajari by 15.8 overnight, a relatively comfortable margin with only four stages remaining.
“It should be enough without anything happening,” Mikkelsen said of his buffer. “We just have to drive at a good pace tomorrow as well, but it's also nice because it keeps us in check for the Power Stage. We'll start tomorrow with a good push and see where we are.”
A consistent day from Emil Lindholm ensured he and co-driver Reeta Hämälainen remained third in the category on their Hyundai i20 N debut. They trailed Pajari by a sizeable 52.6sec but had 43.9sec worth of breathing space to Marco Bulacia behind.
