<p>The present invention relates to a high strength hot dipped galvanized steel sheet for vehicles and, more specifically, to a high strength hot dipped galvanized steel sheet having excellent wettability and plating adhesion and a manufacturing method for the same. The present invention prevents Si or Mn contained in a high strength steel sheet from becoming diffused on the surface of the steel sheet and improves the wettability and plating adhesion of the steel sheet in galvanizing by forming Ni and Co plating layers; and subsequently forming a Fe-Ni alloy layer and a Co layer in order by annealing the steel sheet.
