What are the classification standards for A/B/C-class vehicles?

According to the vehicle classification standards: A-class (including A0/A00) vehicles refer to compact cars, B-class vehicles refer to mid-range sedans, and C-class vehicles are premium sedans. The classification is mainly based on parameters such as wheelbase, engine displacement, and weight. The further the letter sequence goes, the longer the wheelbase, the larger the displacement and weight, and the higher the luxury level of the sedan. A-class vehicles are divided into three categories. Among them, A00 can also be called micro compact cars. The wheelbase of an A00-class sedan should be between 2 meters and 2.2 meters, with an engine displacement of less than 1 liter. For example, the Alto belongs to the A00-class sedan. A0-class sedans have a wheelbase of 2.2 meters to 2.3 meters and a displacement of 1 liter to 1.3 liters, with the typical hatchback being the Xiali. A-class vehicles have a wheelbase range of approximately 2.3 meters to 2.45 meters and a displacement of about 1.3 liters to 1.6 liters. The Jetta from FAW-Volkswagen and the POLO from SAIC Volkswagen are considered classic models in the A-class category. B-class mid-range sedans have a wheelbase of approximately 2.45 meters to 2.6 meters and a displacement ranging from 1.6 liters to 2.4 liters. Models such as the Audi A4, Passat, Zhonghua, and Eastar all belong to the B-class category. 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. Models include the Audi A6, among others. D-class classification; D-class luxury sedans are mostly large in size, with spacious interiors and powerful engines. Their wheelbase generally exceeds 2.8 meters, and the displacement is mostly above 3.0 liters. Common D-class vehicles include the Mercedes-Benz S-Class, BMW 7 Series, Audi A8, Rolls-Royce, and Bentley.
I've been in the auto repair business for thirty years. The classification standards for A, B, and C-segment cars are primarily based on wheelbase size, which is the distance between the center points of the front and rear wheels. A-segment cars are compact vehicles with wheelbases generally ranging from 2400 to 2600 millimeters, like the Honda Fit or Volkswagen Polo. They're nimble and fuel-efficient but have cramped interiors, making rear seats uncomfortable for long rides. B-segment cars are mid-sized, with wheelbases around 2600 to 2800 millimeters, such as the Toyota Camry or Ford Mondeo, offering more spacious interiors suitable for families. C-segment cars are large, with wheelbases exceeding 2800 millimeters, like the BMW 5 Series or Mercedes-Benz E-Class, providing living-room-like comfort at the cost of higher fuel consumption. Classification also considers body length and engine displacement—A-segment cars typically have engines below 1.5L. From my repair experience, A-segment cars often develop electrical issues due to tightly packed components, while C-segment vehicles with heavier chassis cost more to maintain. Choosing a car depends on needs: A-segment cars are hassle-free for daily city commuting in traffic, while B or C-segment suits long-distance travel—though parking becomes challenging. Remember, size affects safety ratings—smaller cars have poorer stability, while larger ones are more stable.
I've owned several cars, and currently drive a used B-segment vehicle. The ABC classification is quite straightforward - it categorizes cars by size, primarily based on wheelbase length. A-segment cars have wheelbases around 2400-2600mm, like the compact Mini Cooper. They're affordable and fuel-efficient, but cramped inside, making it hard for passengers to stretch their legs. B-segment models like my Ford Focus have 2700mm wheelbases, offering decent space and good interiors. C-segment vehicles such as the Audi A6 exceed 2900mm in wheelbase - premium but expensive. The classification also considers track width and curb weight, with smaller cars being lighter and more agile. This affects daily use: A-segment cars are easier to park in cities and save fuel, while C-segment offers sofa-like comfort for long trips at higher fuel costs. When choosing, I consider budget and practicality - young buyers with limited budgets often start with A-segment, while B-segment suits families better. B-segment sells well because it strikes a balance. Don't just focus on brands - test the seating comfort. With prolonged use, pay attention to tire wear patterns which vary across segments.
