The disadvantage of current SUV is the handling. They are big and heavy and come out of the older view of terrain cars as workers. The SAV cathegory tries to bring a new look, as terrain sports cars. They don't carry as much as SUV, but they bring more fun. The comparison of SUV and SAV is similar to the comparison of an ordinary road passenger car and a road sports car dedicated more for fun. But this class is nothing new. It is already longer time represented by SsangYong Actyon, for example, now also the bigger car producers start to consider it seriously. But they pose it at the level of their most luxury road cars and thus X6 should be the more terrain option to the 7 series.
