Cars are classified based on their wheelbase and engine displacement. The classification methods are as follows: 1. A00-class cars have a wheelbase between 2000mm to 2200mm and an engine displacement of 1L or less; 2. A0-class cars have a wheelbase between 2300mm to 2450mm and an engine displacement between 1L to 1.6L; 3. A-class cars have a wheelbase between 2450mm to 2600mm and an engine displacement between 1.6L to 2.0L; 4. B-class cars have a wheelbase between 2600mm to 2750mm and an engine displacement between 1.8L to 2.4L; 5. C-class cars have a wheelbase between 2800mm to 3000mm and an engine displacement between 2.3L to 3.0L; D-class cars have a wheelbase greater than 2800mm and an engine displacement above 3.0L.

Car classification is mainly based on vehicle size, such as wheelbase and length. When I usually drive and choose a car in the city, compact A-segment cars have a short wheelbase under 2.6 meters, making them suitable for narrow-road parking, but they have smaller trunks. Mid-size B-segment cars have a wheelbase of 2.6-2.7 meters, offering comfortable space that can easily fit a baby stroller. Luxury C-segment cars exceed 2.7 meters in wheelbase, providing ample rear legroom, but they are more expensive to fuel and harder to park. Longer wheelbases generally offer better stability, while shorter cars are more agile. In terms of price, most A-segment cars cost under 150,000 yuan, B-segment cars range from 150,000 to 250,000 yuan, and C-segment cars exceed 250,000 yuan. This classification affects daily usage—smaller cars are fuel-efficient and easy to park, while larger cars are better suited for long-distance highway driving. Having driven different segments, I've found that choosing the right one can save both money and hassle.

From a technical parameter perspective, vehicle classification depends on wheelbase and engine displacement. I enjoy studying these details when working with cars. Compact A-segment cars have a wheelbase under 2600mm, paired with small 1.0-1.6L engines - weaker power but better fuel efficiency; B-segment vehicles feature 2600-2750mm wheelbases and 1.6-2.0L engines, offering quicker acceleration and stable highway performance; Luxury C-segment models exceed 2750mm wheelbase with 2.0L+ large-displacement engines delivering strong horsepower plus air suspension for superior comfort. Displacement affects noise and range - small engines run quietly in cities while large ones excel on highways with higher maintenance costs. Safety equipment scales with class - entry-level may have just two airbags whereas premium models can feature up to six. I prioritize matching these parameters to intended usage when selecting vehicles.

Differentiating car classes helps me save money. Class A compact cars are cheap with low insurance and fuel costs, ideal for city commuting; Class B mid-size cars have moderate prices and maintenance, offering spacious practicality; Class C luxury cars incur high expenses with soaring insurance premiums. Driving a Class A saves me hundreds on monthly fuel and parking fees, though it feels less stable on highways. Higher classes consume more resources, with increased maintenance costs—like pricier tire replacements. Choose based on lifestyle: for budget-focused savings, Class A offers the best value.
