What does Audi PA version mean?

[NovaAnn]

Here, PA refers to nylon, which is primarily used in automotive engines and surrounding components. The main varieties include GFPA6, GFPA66, and flame-retardant reinforced PA6 products. Audi models are introduced as follows: 1. A-series: Most Audi models start with the first letter "A" of the company's English name (Audi), such as the Audi A2, A3, A4, A6, and A8 series. The higher the number, the higher the model's grade: A2 and A3 series are compact cars; A4 series are mid-size sedans; A6 series are premium sedans; A8 series are luxury sedans (currently, the A8 is Audi's top-tier sedan). 2. Other series: In addition to the A-series sedans, Audi also has the S series and TT series: The S series mostly consists of high-performance models, though not SUVs, including the S3, S6, and S8; the TT series is entirely composed of sports cars.
