What Are the Criteria for Vehicle Classification?

[DelClara]

Vehicle classification can be divided into six levels: A00, A0, A, B, C, and D. The classification is primarily based on parameters such as wheelbase, engine displacement, and weight. The further the letter is in the alphabet, the longer the wheelbase, and the larger the displacement and weight of the vehicle in that category. Below are the vehicle classifications: A00 level: The wheelbase should be between 2 meters and 2.3 meters, with an engine displacement of less than 1 liter. A0 level: The wheelbase ranges from 2.3 meters to 2.5 meters, with a displacement of 1 to 1.5 liters. A and B levels: The wheelbase ranges approximately from 2.5 meters to 2.7 meters, with a displacement of about 1.5 to 2.0 liters. Mid-range passenger vehicles in the B level have a wheelbase of about 2.7 meters to 2.9 meters, with a displacement ranging from 1.8 liters to 2.5 liters. High-end passenger vehicles in the C level have a wheelbase of about 2.8 meters to 3.0 meters, with an engine displacement of 2.3 to 3.0 liters.

I've been studying car classifications for a while and find it quite fascinating. Vehicle classes are mainly determined by body size and wheelbase. For example, the A00 class refers to microcars with wheelbases just over 2 meters, like the Wuling Hongguang MINIEV. A-segment cars typically have wheelbases between 2.5 to 2.7 meters - common models like the Corolla and Lavida are classic compact cars. When it comes to B-segment vehicles such as the Accord and Camry, their wheelbases exceed 2.8 meters, offering noticeably more spacious interiors. Actually, factors like displacement and equipment also influence classification. C-segment cars often feature engines above 2.0T, with models like the Audi A6 equipped with premium features such as air suspension. The current trend shows new energy vehicles redefining classifications - for instance, the Tesla Model 3 has B-segment dimensions but delivers performance comparable to traditional C-segment cars.

When discussing vehicle classification, I believe there are three main aspects to consider: size positioning, price range, and brand premium. Entry-level compact cars like the Fit, with a length under 4 meters, offer affordable pricing; midsize SUVs such as the Highlander, exceeding 4.8 meters in length, serve as primary family vehicles. Luxury car classifications are even more distinct—the Mercedes C-Class and S-Class differ by two tiers. Interestingly, new energy vehicles are breaking traditional rules. For instance, the NIO ET5, with a 2.88-meter wheelbase, is classified as a B-segment car, yet its intelligent features surpass many C-segment models. In reality, consumers are increasingly disregarding official classifications, focusing more on actual interior space and tech features, as wheelbase numbers are far less tangible than the in-car experience.

I often discuss car classification with friends, and the simplest way to judge is by measuring the wheelbase. Below 2.7 meters is considered compact, which covers most family cars; between 2.7 and 2.9 meters is midsize, with the Accord being a typical example; anything over 2.9 meters is generally executive class. Of course, powertrain configuration is also crucial—a regular B-segment car might come with a 1.5T engine, while luxury brands often use a 2.0T for models in the same segment. Actually, classification standards vary by country: Germans prioritize displacement, Americans categorize by weight, and here in China, we mainly follow standards evolved from European norms.

When it comes to car classifications, the most intuitive difference I notice is in size. It's most obvious in parking lots: A-segment cars like the Golf, which is about 4.2 meters long, are very maneuverable when parking; B-segment cars such as the Passat, approaching 4.9 meters, offer enough rear legroom to cross your legs comfortably; while D-segment models like the Mercedes S-Class exceed 5.3 meters and require specially designated large parking spaces. Equipment differences are also reflected in these classifications – compact cars in the 100,000 RMB range might come with manual air conditioning, whereas mid-size cars around 300,000 RMB typically feature dual-zone automatic climate control. The new trend is that electric vehicles are blurring these traditional boundaries. For instance, the Zeekr 001 clearly falls into the C-segment size category but is marketed as a shooting brake coupe.

Car classification standards are actually quite flexible. When I was buying a car, I noticed that there might be cross-segment options at the same price point. Traditionally, classification is based on wheelbase: micro cars under 2 meters, subcompact cars 2-2.5 meters, compact cars 2.5-2.7 meters, midsize cars 2.7-2.9 meters, and full-size cars 2.9-3.1 meters. However, the actual experience matters more. For example, the Peugeot 408 has a 2.73-meter wheelbase, technically making it an A+ segment car, but its interior space is more spacious than some B-segment vehicles. Luxury brands have even more interesting classifications—the front-wheel-drive Lexus ES is categorized as a full-size car but is considered half a grade lower than the rear-wheel-drive BMW 5 Series. With the rise of domestic brands, cars like the BYD Han, which has a wheelbase approaching 3 meters, are priced similarly to joint-venture B-segment models.
