Which type originated in the auto racing industry?

• A. Space Frame
• B. Full Frame
• C. Unibody
• D. Frame Ring

Answer: (A)

Space frame designs were developed to meet racing needs: a lattice of tubes connected at joints creates a lightweight yet exceptionally stiff skeleton that can handle high loads and torsional twisting from aggressive cornering. This approach lets engineers tune chassis geometry precisely for different tracks and regulations, while keeping weight down and allowing rapid iteration on suspension and aerodynamics. In racing, every gram counts, and the space frame delivers strength where it matters without the bulk of a solid frame. By contrast, a traditional body-on-frame setup attaches the body to a separate rigid frame and tends to be heavier, while unibody integrates the shell and structure into one piece for mass production and safety but doesn’t originate from racing chassis practice. Frame ring isn’t a standard automotive term for a chassis concept, so it isn’t a recognized origin in this context. Therefore, the type that originated in the auto racing industry is the space frame.
