Neat way to package things, with battery and motor (heaviest components) mounted central to the chassis. Being a concept, hardware appearance is a non-issue. I would imagine that what you gain from 4-wheel steering around corners, you loose down the straights trying to manage traction and keep a straight line. Plus, the lack of a center diff would pose jumping/rough track issues as well.
