The World champion Sebastien Loeb is poised to wrap up his fifth win in five races this season after opening up a 57 second lead over Citroen teammate Dani Sordo at the Rally of Argentina.
Loeb, who's won all four events this year in 2009 and is chasing a fifth career win in Argentina, benefited from seeing Ford Focus driver Mikko Hirvonen lose vital time late in the day when his engine overheated.
