How are sedan classes divided?

[AllisonDella]

Sedan classes are generally divided into four levels: A, B, C, and D. There are significant differences in wheelbase and engine displacement among sedans of different classes. Below is an introduction to the wheelbase and engine displacement of each class: 1. Class A: The engine displacement of sedans in this class is generally less than 1L; their wheelbase ranges between 2000-2200mm. Vehicles in this class are typically lower-end models. 2. Class B: The engine displacement of sedans in this class is generally 1.6-2.4L; their wheelbase ranges between 2450-2600mm. Vehicles in this class are typically ordinary family cars. 3. Class C: The engine displacement of sedans in this class is generally 2.3-3.0L; their wheelbase ranges between 2600-2800mm. Vehicles in this class are typically mid-range models. 4. Class D: The engine displacement of sedans in this class is generally 3.0L or above; their wheelbase is over 2800mm. Vehicles in this class are typically higher-end models.
