There are different approaches to evaluating driving dynamics. Test drivers and motorsport drivers are often guided by their own perception and experience when analyzing and optimizing vehicles. A measurement perspective, which relies on reproducible, technically verifiable measurements, frequently for the safety of chassis and other vehicle components, differs from this. When testing the Czinger 21C's handling stability and the durability of its components, Divergent 3D's test engineers focused on technically verifiable measured data. By studying the forces and moments that act on the wheels from the outside, it was possible to verify and optimize processes and draw conclusions about, for example, different material mixes or tire profiles, and about the safety of the various assistance systems.
