Juho Hanninen holds the lead of Rally Argentina following the opening loop of stages on Saturday morning.
Defending IRC title winner Kris Meeke had led the way after the Friday evening superspecial stage, but Hanninen went quickest on the first stage of the morning to jump from fourth to first.
The Skoda driver then went quickest on both SS3 and SS5 to head back to service in Carlos Paz with a 13.5 second advantage over Meeke.
The Peugeot driver, who was reporting an issue with the engine on his 207 S2000, ends the morning just 0.2 seconds ahead of fellow Briton Guy Wilks – who topped the times on the 21.53km fourth stage from Santa Rosa to San Agustin.
The second factory Skoda of Jan Kopecky sits in fourth although the Czech driver is nearly a minute off the pace, with WRC regular Federico Villagra
fifth on his debut with the M-Sport Ford Fiesta.
Gabriel Pozzo lies sixth in his Subaru Impreza STi, with Nasser Al-Attiyah's Skoda and the Peugeot of Bruno Magalhaes rounding out the top eight.
