Cars are classified into A00 class (micro cars), A0 class (subcompact cars), A class (compact cars), B class (mid-size cars), C class (large cars), and D class (luxury cars). The following are specific methods to distinguish car classes: 1. Wheelbase: below 2350mm is micro car; 2350mm-2500mm is subcompact car; 2500mm-2700mm is compact car; 2700mm-2800mm is mid-size car; 2800mm-2900mm is large car; above 2900mm is luxury car. 2. Length: below 3.7M is micro car; 3.7-4.3M is subcompact car; 4.3-4.6M is compact car; 4.6-4.9M is mid-size car; 4.9-5.1M is large car; above 5.1M is luxury car.

I categorize cars by price and brand, which is simple and practical. Mainstream family cars like and Toyota, ranging from a hundred thousand to three hundred thousand, focus on practicality and reliability. Luxury cars like Mercedes-Benz and BMW, starting from four to five hundred thousand, come with premium features like leather seats and air suspension. Supercars like Porsche and Ferrari, priced over a million, offer top-tier performance with distinct engine sounds. The same goes for new energy vehicles: BYD at two to three hundred thousand is practical, Tesla at over four hundred thousand is tech-savvy, and the million-dollar Lotus pure electric is for the ultimate experience. Choosing a car based on your budget is the easiest way.

Classifying cars by body size is quite straightforward. Small cars and compact cars are like studio apartments, where three adults in the back seat can't even stretch their legs. Midsize cars and midsize SUVs are comparable to two-bedroom apartments—models like the Accord and Magotan offer just enough space. Full-size SUVs and luxury sedans are definitely at the villa level, with over five meters in length and a three-meter wheelbase, equipped with features like boss buttons and rear screens. I've also noticed that the larger the vehicle, the more comprehensive the safety features. For example, behemoths like the Escalade come standard with ten airbags. The more expensive the car, the more emphasis on safety—this rule never fails.

Looking at the engine and displacement is the most practical. A 1.5L naturally aspirated engine is basically for entry-level cars, which is fine for daily commuting. The 1.5T to 2.0T range is considered mainstream, used in SUVs like the CR-V, providing enough power for acceleration and overtaking. A 3.0T six-cylinder engine is where the high-end starts—the X5's engine sound even has a subwoofer effect. For electric vehicles, motor power is similar: 170 kW is average, while 350 kW is performance-level. Displacement doesn’t lie—the bigger it is, the more expensive, that’s the iron rule.

Seat configurations can really tell the hierarchy - basic fabric seats with manual adjustment are usually entry-level models. Leather power seats with heating are mainstream features, even standard on models like the Highlander. Moving up to executive-class vehicles, you get rear seats with massage functions and leg rests, paired with premium audio systems like Bowers & Wilkins. I've also noticed luxury cars often feature semi-aniline leather steering wheels, far superior to regular Nappa leather in texture. These configurations are like building blocks - every additional feature comes with a price tag.

The real core difference lies in the chassis platform. Most MQB platform vehicles, like the Sagitar, are compact models that offer a decent but unremarkable driving experience. In contrast, the A6 built on the MLB platform provides a noticeably smoother ride, effortlessly gliding over speed bumps without any jolts. Nowadays, pure electric platforms with 800V high-voltage architecture clearly stand out as more advanced, offering faster charging and lower energy consumption. Chassis materials also vary in quality—MacPherson struts are considered basic, while double-wishbone suspensions with CDC electromagnetic damping represent the high-end options. These intrinsic differences are far more significant than mere exterior aesthetics.
