Generally speaking, there are A, B, C and D cars, and the standards vary from country to country, but there is no unified standard in China. Because German cars were the first joint venture with China and occupied a certain market, the German classification method was adopted:

According to German automobile classification standards, A-class cars include A0 and A00, generally referring to small cars; B-class car is a mid-range car; C-class cars are high-end cars; D-class cars refer to luxury cars, and the classification is mainly based on parameters such as wheelbase, displacement and weight. The later the alphabetical order, the longer the wheelbase, the greater the displacement and weight of this class of cars, and the luxury of cars is also constantly improving.
