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, the larger the displacement and weight, and the higher the luxury level of the car.

The name Audi A4L B9 actually refers to the A4 model of the Audi brand. The 'L' stands for Long-wheelbase, meaning the extended wheelbase version, which is particularly popular in the Chinese market due to its spacious rear seating and enhanced comfort. 'B9' is the chassis code, indicating it's the fifth-generation A4 model, produced since around 2015, distinguishing it from the previous B8. This generation features a more modern exterior and upgraded interior with high-tech configurations like the digital dashboard and MMI system. It offers good handling but has a relatively firm suspension setup. If you're considering buying a used car, the B9 is generally regarded as reliable with good fuel economy. Common issues might include minor electronic glitches, and it's recommended to use genuine parts for maintenance to avoid potential problems.

The name of the Audi A4L B9 can be broken down for analysis. A4 represents Audi's mid-size sedan series, while the L stands for the long-wheelbase version. The extended wheelbase allows rear passengers to stretch their legs, significantly improving comfort, especially on long trips. B9 denotes the chassis code, which is the generational model number, indicating it belongs to the fifth-generation product. This generation's engines primarily feature turbocharging, such as the 2.0T, paired with the quattro all-wheel-drive system for stable power delivery. Compared to the previous B8 generation, the B9 has made improvements in lightweight design, making it feel more agile and fuel-efficient. However, the transmission may occasionally exhibit jerky behavior in city traffic, requiring some adaptation. Owner feedback suggests that routine maintenance costs are moderate, but attention should be paid to electrical systems, such as occasional minor issues with the headlight module. Regular checks are recommended to ensure driving safety.
