Mainly refer to the vehicle's wheelbase and length parameters to distinguish between Class A, B, C, and D vehicles. Below are the relevant details: 1. Detail one: Vehicle classes are generally divided into six levels: A00, A0, A, B, C, and D, where A00 refers to micro cars, A0 to small cars, A to compact cars, B to mid-size cars, C to full-size cars, and D to large cars. 2. Detail two: Micro cars have a wheelbase of 2-2.3m and a length of less than 4m. Small cars have a wheelbase of 2.3-2.5m and a length of 4-4.3m. Compact cars have a wheelbase of 2.5-2.7m and a length of 4.2-4.6m. Mid-size cars have a wheelbase of 2.7-2.85m and a length of 4.3-5m. Full-size cars have a wheelbase of 2.85-3m and a length of more than 5m. Large cars have a wheelbase of 2-2.3m and a length of more than 5.2m.

Having been in the automotive industry for a long time, I distinguish between A, B, C, and D-segment cars mainly based on size, wheelbase, and purpose. A-segment represents the smallest city cars, like the BYD Dolphin or Volkswagen Polo, typically with a body length under 4 meters and a wheelbase around 2.4 meters. They are agile to drive but cramped in space, ideal for singles or young couples commuting. B-segment cars are slightly larger, such as the Honda Civic or Toyota Corolla, with lengths between 4-4.3 meters, offering moderate space for both city driving and short trips. C-segment refers to family-oriented midsize cars like the Honda Accord or Hyundai Sonata, measuring 4.3-4.6 meters in length, featuring spacious interiors and strong storage capacity. D-segment represents mid-to-large or entry-level luxury cars like the Volkswagen Passat or Mercedes-Benz C-Class, exceeding 4.6 meters in length with a wheelbase over 2.7 meters, equipped with high-end features and superior comfort, suitable for business or family long-distance travel. When choosing a car, consider your budget: A-segment cars may start at 50,000-80,000 RMB, fuel-efficient but prone to instability at high speeds; D-segment cars cost 200,000+ RMB, offering stability and sophistication. I believe this classification helps consumers quickly identify their needs—opting for an A-segment car saves fuel and money, but for weekend getaways, a C-segment or above is preferable.

During my years working at the car dealership, I've developed a simple method to distinguish car classes: use a ruler to measure the body length and wheelbase. A-class cars like the Wuling Hongguang MINI or Suzuki Swift are no longer than 4 meters in total length, compact and maneuverable for easy city driving; B-class cars such as the Kia K3 or Ford Focus are around 4.2 meters, offering good practicality; C-class models like the Volkswagen Sagitar or Haval H6 measure about 4.5 meters with ample space; D-class vehicles such as the Buick Regal exceed 4.8 meters, providing spacious luxury. The wheelbase differences are significant—A-class cars have shorter wheelbases, making them agile in turns but more bumpy; D-class cars with longer wheelbases offer stable high-speed performance ideal for long trips. In terms of price range, A-class cars under 50,000 yuan are affordable but have lower insurance coverage; D-class cars over 250,000 yuan come with expensive parts and maintenance costs. I often remind buyers to choose based on terrain—small cars for narrow neighborhoods, larger cars with more airbags for highway safety. Fuel consumption is another factor—A-class cars save fuel at 6 liters per 100 km but have weaker heating in winter.

As an average car owner, I differentiate car classes based on feeling and size when purchasing. Class A cars like the Chery QQ or Baojun 310 are compact, making them easy to park in the city and economical; Class B models such as the Nissan Sylphy or Volkswagen Golf are slightly larger and more practical for family use; Class C vehicles like the Toyota Camry or Honda CR-V offer comfortable and spacious interiors; Class D cars such as the Audi A4 or Volkswagen Passat exude a strong sense of luxury. In terms of length, Class A cars are under 4 meters, easy to maneuver but cramped in the back seats; Class B cars are just over 4 meters, suitable for small families; Class C cars are around 4.5 meters with larger luggage areas; Class D cars approach 5 meters, making them prestigious for business use. Price-wise, Class A cars start at tens of thousands, being entry-level; Class C cars around 150,000 RMB offer good value for money. Driving experience varies: Class A cars are fuel-efficient and agile; Class D cars are smooth but consume more fuel. I recommend young commuters opt for Class A cars; those with increased budgets after job changes can upgrade to Class B or C.
