Abstract:Split-body styling creates a new field of automotive exterior design which is different from uni-body styling, which has breakthrough meaning as for design, however the air drag will come up to be a new problem. Based on A segment vehicle as reference, it built split-body low-drag basic form, which was considered in the aspect of ergonomics so as to insure the engineering rationality. It started vehicle design with verified basic form. It transformed basic form into real car while keeping the form low-drag by adding details while taking aerodynamic simulation. Eventually, it found design methods related to both design and aerodynamics and obtained one low-drag split-body design proposal, CD of which is 0.2249.
