Our preliminary chassis design is a combination of steel and aluminum honeycomb elements, with some reinforced polymer carbon fiber as the seat and nose cone(not shown). This chassis is still being optimized and tested using finite element analysis software to prove structural stiffness and torsional rigidity.
Currently designed for extremely easy manufacturing, complexity will undoubtedly increase as the design progresses. As it stands this chassis is looking extremely lightweight, under 50 pounds total, although that will increase with higher complexity designs.
