Sébastien Ogier took the lead early on, but made a mistake whilst driving in heavy fog.
He lost forty seconds, allowing Loeb to seize the advantage.
Jari-Matti Latvala and Mikko Hirvonen fought over the final podium position until Hirvonen's Citroën DS3 WRC developed an electrical problem.
Latvala could not afford to rest, as he found himself fighting with Evgeny Novikov.
A late charge on the final day—including the fastest time on the power stage—was enough for Latvala to secure third place and his first podium in Argentina.
