Audi A1: 8X and GB generations, engines and trims
Audi A1 — the smallest Audi model, where city car size meets higher-class refinement. We look at how the 8X and GB generations differ, which engines are most popular, how the trims vary and what to check when buying a used A1.
A1 in brief
The A1 has been in production since 2010 and shares much of its technology with the Volkswagen Polo, but stands out with a more premium interior and Audi styling. It's a popular choice for those seeking a small, economical yet solid car.
The first generation came with 3-door and 5-door Sportback bodies, the second only as a 5-door Sportback, and since 2019 as the higher, crossover-style A1 citycarver (later renamed allstreet).
8X and GB — how they differ
The first generation 8X (2010–2018) is based on the same platform as the contemporary Polo. From 2014–2015, refreshed models received newer engines, including the three-cylinder 1.0 TFSI and 1.4 TDI. This generation is cheaper on the used market and includes diesel versions.
The second generation GB (from 2018) is built on the MQB A0 platform, like the newer Polo. It's longer, roomier, with a digital instrument cluster and more modern multimedia. Diesel engines are no longer available — only petrol TFSI units are offered.
If you need more space at the rear and modern features, opt for the GB generation. The 8X is worth considering if budget is tight, but in that case, the technical condition and service history are crucial.
Engines and gearboxes
The 8X most commonly features 1.2 and 1.4 TFSI engines, with the facelift introducing 1.0 and 1.4 TFSI petrol units and 1.4 and 1.6 TDI diesels. The sportiest versions include the roughly 185hp 1.4 TFSI and the all-wheel-drive S1 with around 230hp 2.0 TFSI engine.
In the GB market, engines are designated by power output: 25 TFSI (around 95hp) and 30 TFSI (around 110hp) have a three-cylinder 1.0-litre unit, 35 TFSI is a 1.5-litre (around 150hp), and 40 TFSI is a 2.0-litre (around 200hp).
Transmissions are manual or S tronic (dual-clutch). Smaller engines are often paired with a 7-speed dry-clutch S tronic gearbox.
What to check when buying a used A1
The S tronic gearbox should engage smoothly: juddering, clunks when shifting, or vibrations in the shifter often indicate a need for transmission or mechatronics repair.
Early 8X models with 1.2 and 1.4 TFSI engines had a timing chain that could stretch — a cold engine shouldn't rattle after starting. For diesels that have done a lot of city driving, check the diesel particulate filter (DPF).
The A1 is often bought as a first or second family car and spends a lot of time in the city, so check the bumpers, alloy wheels, and gearbox. Inspect the ride using service records and maintenance logs.

Comparison of GB generation trims
| Bazinė | advanced | S line | |
|---|---|---|---|
| Who it suits | For daily city driving | For comfort and style | Sporty styling |
| Wheel sizes (most common) | 15–16 inch | 16–17 inch | 17–18 inch |
| Front headlights | Halogen or LED | Often LED | LED |
| Engine | 25–30 TFSI | 30–35 TFSI | 30–40 TFSI |
| Price in the used market (relatively) | Budget-friendly | Mid-range | Premium |
For most buyers, the best choice is the 30 TFSI with advanced or S line trim. The 40 TFSI is worth considering only if you're after a sporty car, as there aren't many of these around.

- Economical engines
- Compact and comfortable in the city
- Holds its value well
Cons
- More expensive than the Polo and similar cars
- Risk of chain issues with early TFSI engines and S tronic gearboxes
- Limited space in the back, especially in the 3-door version
Frequently asked questions
How does the Audi A1 differ from the Volkswagen Polo?
The technology and engines are very similar, but the A1 offers a more premium interior, a distinct design, and usually more features. This means you'll pay more for a used A1 than a similarly aged Polo.
Which A1 generation should you choose?
If your budget allows, opt for the GB generation — it's roomier and more modern. First-generation models are best chosen post-2015 refresh, when newer engines were introduced.
Is the A1 suitable for a family?
As a primary family car, the A1 is often too small — the rear seats and boot are cramped. It's better suited to city driving or as a second family car.
