How are sedans classified?

[LolaAnn]

Sedans are classified into six levels: A00, A0, A, B, C, and D. According to the German car classification standard: A00 refers to micro passenger cars, A0 to small passenger cars, A to compact passenger cars, B to mid-size passenger cars, C to mid-to-large passenger cars, and D to large passenger cars. This is not an authoritative standard but rather a set of reference values initially established by Volkswagen for its platform strategy, which later became widely adopted. In China, A00, A0, A, B, C, and D levels are referred to as micro cars, small cars, compact cars, mid-size cars, mid-to-large cars, and large cars, respectively.
