According to vehicle classification standards, the primary parameters include wheelbase, engine displacement, weight, etc. The further the letter is in the alphabet, the longer the wheelbase, larger the displacement and weight, and the higher the luxury level of the sedan. The specifics are as follows: A-class vehicles: Including A0 and A00 class, generally referring to compact cars. B-class vehicles: These are mid-size sedans. C-class vehicles: These are premium sedans. D-class vehicles: These refer to luxury sedans. With the increasing variety of models and the growing diversity in price, style, and configuration options, the boundaries between A-class, B-class, and C-class vehicles are becoming more blurred. For example, some models may have a wheelbase that falls within the A-class range, while their displacement and price are nearly comparable to B-class vehicles. Therefore, vehicle classification should not be overly rigid and requires flexible handling.
