I've been driving Audi cars for five years and have a clear understanding of their series classification. The sedan lineup ranges from the compact A3 to the flagship A8, with evergreen models like the A4 and A6 in between. On the SUV side, there's the entry-level Q2, the family-oriented Q5 and Q7, and the coupe-styled Q8. Performance enthusiasts love the S and RS series, such as the S4, which is like a wolf in sheep's clothing. The new energy sector is in full swing, with the e-tron series including SUVs and GT sports cars, as well as pure electric models like the Q4 e-tron. A special mention goes to the sports car line—although the TT has been discontinued, the R8 still upholds the tradition of naturally aspirated engines, and its exhaust note is absolutely thrilling. These series cater to different demographics, and I've test-driven almost every model.

Last week, I accompanied a friend to pick up a Q5 and took the opportunity to chat with the salesperson about Audi's product lineup. It’s mainly divided into three categories: sedans with numbers and letters, like the A4, a family favorite; SUVs starting with Q, with the all-electric Q4 e-tron currently being the hottest; and performance models with letters, such as the RS6 Avant, which can handle both grocery runs and track days. Audi is moving fast in the new energy sector, with the e-tron GT launched last year sharing a platform with Porsche. In the classic sports car line, the R8 is about to get a new generation. Actually, Audi’s naming system is quite logical: the first letter indicates the vehicle type, and higher numbers signify a more premium positioning.

As an automotive reviewer, I frequently film comparison videos across Audi's entire lineup. The foundation is the A-series sedans, with sizes increasing from the A3 to the A8. SUVs are all named with Q prefixes, ranging from the compact crossover Q2 to the seven-seater Q7. The performance line has two tiers: S models feature sporty tuning, while RS versions are track-focused machines. The new energy vehicle portfolio is fully electrified, with the e-tron series covering sedans/SUVs/GT sports cars. Special mention goes to the mid-engine R8 supercar - its naturally aspirated V10 is practically a swan song. When viewing these series at dealerships, sales staff will recommend corresponding product lines based on your needs.
