Sedans can be classified based on wheelbase, engine displacement, and weight. Below are the specific classification methods: 1. Class A vehicles: A00-class sedans have a wheelbase between 2 meters to 2.2 meters and an engine displacement of less than 1 liter; A0-class sedans have a wheelbase of 2.2 meters to 2.3 meters and a displacement of 1 liter to 1.3 liters; Generally, Class A vehicles have a wheelbase ranging from approximately 2.3 meters to 2.45 meters and a displacement of about 1.3 liters to 1.6 liters. 2. Class B vehicles: B-class mid-range sedans have a wheelbase of about 2.45 meters to 2.6 meters and a displacement ranging from 1.6 liters to 2.4 liters. 3. Class C vehicles: C-class premium sedans have a wheelbase of approximately 2.6 meters to 2.8 meters and an engine displacement of 2.3 liters to 3.0 liters. 4. Class D vehicles: D-class luxury sedans mostly feature a majestic appearance, extremely spacious interiors, and very powerful engines. Their wheelbase is generally greater than 2.8 meters, and the displacement is mostly above 3.0 liters.

I've driven many cars, and the most common way to classify sedans is by size. Generally, they are divided into compact sedans, which are small, fuel-efficient, easy to park in cities, and affordable; midsize sedans offer more spacious interiors suitable for family use, such as comfortable rear seats; and large sedans are often luxury vehicles with high-end configurations and powerful performance, but with higher fuel consumption. Classification can also be based on wheelbase length, with short wheelbases offering agility and long wheelbases providing stability. Different brands have slightly varying classification standards, with Japanese cars leaning towards practicality and German cars emphasizing performance. When actually purchasing a car, size determines daily convenience and ride comfort, so it's important to choose based on personal needs. Additionally, energy types like electric or hybrid are becoming increasingly popular, but size remains a fundamental reference point.

As a long-time observer of the automotive market, I believe sedan classifications are primarily based on body size and segment. There are A0-segment compact cars like the MINI, ideal for beginners; B-segment family sedans like the Honda Accord offering balanced space; and C-segment luxury models such as the Mercedes-Benz S-Class for premium comfort in business settings. Size directly influences wheelbase and interior space, and also correlates with pricing and maintenance costs. Market segmentation also considers consumer demographics: young buyers favor compact models, families prefer mid-size options, while the affluent opt for full-size vehicles. Technological advancements have introduced new categories, such as electric vehicles like the Tesla Model 3 forming their own segment. Safety features like ABS or airbags sometimes serve as reference points, but size and segment remain the core framework.

When buying a car, I usually categorize sedans by price range. Entry-level sedans are the most affordable, with basic features that are practical and fuel-efficient; mid-level sedans offer great value for money, with more configurations and comfort; luxury sedans are high-end, with powerful performance and lavish interiors. Price directly reflects differences in quality and brand. When on a tight budget, compact cars are the most practical; with a moderate budget, mid-range models offer more space; with a high budget, you can go straight for the luxury experience. The classification is also influenced by fuel consumption and safety. Entry-level cars are economical but generally have average safety, while luxury cars provide comprehensive protection but consume more fuel. When choosing, match your financial capability and daily needs to avoid waste.
