How are cars classified into different grades?

[ElliottRose]

Currently, the most widely used method for classifying cars is the German system, which divides vehicles into A00, A0, A, B, C, and D grades. This classification is primarily based on parameters such as wheelbase, engine displacement, and weight. Below is relevant information: 1. Since engine displacement is difficult to determine unless you are familiar with the specific car, and the platform is even harder to identify than engine displacement, the most common method of classification is by wheelbase length. 2. Micro cars (A00 grade) typically refer to models with a wheelbase below 2400mm. Small cars (A0 grade) usually refer to models with a wheelbase between 2400-2550mm. Compact cars (A grade) generally refer to models with a wheelbase between 2550-2700mm, and this category represents the mainstream of family sedans. Midsize cars (B grade) typically refer to models with a wheelbase between 2700-2850mm, and this category often serves both family and business purposes. Full-size cars (C grade) usually refer to models with a wheelbase between 2850-3000mm, and this category represents the mainstream of business vehicles.
