Audi A1 models and trim levels explained

The Audi A1 was a watershed moment for the carmaker.

It was the first time in the brand's modern era that it'd slapped its iconic four-ringed badge on a supermini-sized hatchback. The combination of small car and big luxury proved to be a popular one, with the car staying on sale for 16 years.

This guide will walk you through the Audi A1 lineup and its model generations over time.

Audi A1 models explained

The A1 isn't Audi's first foray into the supermini segment. That honour belongs to the Audi 50 hatchback of the 1970s, which actually became the first Volkswagen Polo after a little rebadging. The Polo connection continued for the A1, with the little Audi borrowing the VW's chassis and engines.

Of the 'big three' German luxury carmakers, Audi was the only one to build an own-brand supermini in the 21st century. BMW tackled that market through its Mini lineup, while Mercedes' attempts were limited to its Smart brand – which it's since part-sold to Volvo parent company, Geely.

Being basically the only premium car in the segment, the A1 was automatically set above mainstream rivals like the Ford Fiesta, Peugeot 208 and Renault Clio. Its desirability carried the car for 16 years and two model generations, with 2026 being the A1's final year on sale.

Audi A1 Quattro and Audi S1

Audi A1 Quattro and S1 side by side

Audi's built two high-performance versions of the A1.

The first is the A1 Quattro – an ultra-limited edition powered by a 252hp turbo petrol engine, with four-wheel drive and a manual gearbox. It also got a unique body kit, 'turbine'-style alloy wheels and menacing red flashes in its headlights.

Serving as a more regular production version of the A1 Quattro, the S1 was available until the end of the first-generation A1's production run. It uses basically the same setup as the A1 Quattro, but with power very slightly tamed to 231hp.

Audi A1 Citycarver

The second-generation A1 never got a true performance model like its predecessor, although the rare 40 TFSI used the same engine as the Volkswagen Polo GTI. Instead, it was bestowed with a unique model in the form of the Citycarver. This version aped the look of chunkier SUVs like the Audi Q2, with lifted suspension and more rugged body details. The car was mechanically unchanged from the standard A1, but the extra ride height gives drivers a little more confidence over potholes and jagged kerbs.

What's the best Audi A1 model?

Both of the A1's two model generations feel fairly similar on the open road, with well-judged suspension and composed handling. However, newer 2018-onwards models are a bit more practical than their predecessors and feel substantially higher tech thanks to their large, glossy infotainment screens and driver displays.

Don't fret if your budget will only stretch to a first-generation A1, however. This car still feels like a premium product behind the wheel, with smooth, zippy engines and a slick optional automatic gearbox. Its only downside is the small flip-up infotainment screen, which now looks quite dated.
