1. A chassis assembly having mixed material for reduced mass, the assembly comprising:
an upper structure being one of a metallic single piece and a metallic multi-piece, the upper structure having a plurality of first bond surfaces, each of the first bond surfaces being parallel with each other at varying elevations relative to a z-axis of a 3-dimensional coordinate thereof;
a lower structure made of a polymer composite, the lower structure having a plurality of second bond surfaces, each of the second bond surfaces being parallel with each other at varying elevations relative to the z-axis thereof, the second bond surfaces being arranged to align with the first bond surfaces in complementing relation such that the lower structure is joined with the upper structure at the first and second bond surfaces; and
an adhesive disposed between and in direct contact with the first and second bond surfaces to join the lower and upper structures at the first and second bond surfaces, defining a bond gap between the first and second bond surfaces, wherein the first bond surfaces are disposed above the second bond surfaces when the lower and upper structures are joined.
