GZ-X series took a stab at notching up mainstream tier one chassis standards and was designed for that purpose. It will continue to do so for its entire dynasty. The series takes the complexity and ingenuity common on high-end chassis, and re-engineers them into the mainstream space. Mainstream trends, like dual-tone shades and colors, simplicity with style and corporate consistency come into play to make up the exterior, with efficiency and convenience coming in to accommodate the interior.
