Audi A1 GB (2018 – 2025)

Reliability score : 7.8/10

The second-generation Audi A1 (Type GB) marks a clear break from its predecessor (8X). Based on the Volkswagen Group's MQB A0 platform (shared with the VW Polo VI and Seat Ibiza V), it definitively abandons the 3-door body style to be offered exclusively as a 'Sportback' (5-door). Notably, Audi completely banned diesel (TDI) and hybridization from this generation, offering a 100% gasoline range. While its exterior design is praised for its aggressiveness (inspired by the 1984 Audi Sport quattro) and its road handling is significantly improved, this generation has been sharply criticized for the regression in the quality of its interior plastics, unworthy of the premium badge, especially given the prices charged. A 'Citycarver' version (renamed 'Allstreet' in 2022) with an adventurous look

✅ Strengths

Dynamic road handling and rigorous chassis (MQB A0)
Very refined sound insulation for the category
Onboard technology (Virtual Cockpit as standard, responsive MMI)
Efficient and powerful gasoline engines (especially the 35 TFSI)
Assertive and customizable exterior design

⚠️ Weaknesses

Significantly reduced interior plastic quality (many hard plastics)
Prohibitive purchase price and option costs
Reliability of the S tronic 7 gearbox (DQ200) still imperfect
Total absence of hybrid or electric powertrains
Average rear passenger space and access to rear seats

🎯 Verdict

The Audi A1 GB is a city car with a striking design and first-class road performance. However, it commands a very high price for its badge, especially since its interior finish has regressed compared to the previous generation. In terms of reliability, the gasoline (TFSI) engines are generally mature and robust. The real downside remains the S tronic 7 automatic gearbox (DQ200) on smaller engines, which requires absolute vigilance when buying used. Buying advice: Opt for a 30 TFSI (110/116 hp) version with a manual gearbox for complete peace of mind, or a 35 TFSI if you do a lot of road driving. If you insist on an automatic gearbox, demand a clear service history and a warranty.
