What is the difference between A-class and B-class cars?

[OAdriana]

A-class and B-class cars differ in the following aspects: 1. Vehicle type: A-class cars are referred to as compact cars; B-class cars are referred to as mid-size cars. 2. Wheelbase: A-class cars typically have a wheelbase ranging from 2550 to 2700mm; B-class cars usually have a wheelbase between 2700 and 2850mm. Vehicle classifications can be further divided into six levels: A00, A0, A, B, C, and D, based on parameters such as wheelbase, engine displacement, and weight. China also has its own classification standards, categorizing vehicles into micro cars, small cars, compact cars, mid-size cars, full-size cars, and large cars. SUVs follow a similar classification system.
