If you're looking for a premium hatchback, Audi offers two compelling options at different ends of the market. The A1 is a sophisticated supermini, while the A3 is a larger, more established family car. Both deliver the upmarket design, quality interior, and desirable four-ringed badge that buyers expect.
The A1 brings that premium feel to the compact class, competing with the likes of the MINI Hatchback. The A3, a rival to the BMW 1 Series and Mercedes-Benz A-Class, offers more space and technology for those with a bigger budget and family. So, should you go for the compact and stylish A1, or is it worth stretching to the more practical A3?

Practicality
Audi A1 practicality score: 3/5
Audi A3 practicality score: 4/5
For a compact car, the Audi A1 is quite practical. Its 335-litre boot is generous for the supermini class, and the rear seats offer enough room for adults on shorter journeys. It’s a usable space that works well for singles or couples.
As you’d expect from the car in the class above, the A3 offers more room. Its 380-litre boot is competitive in the family hatchback segment, and there’s more leg and shoulder room for passengers in the back. The A3 is also available as a saloon, which provides an even larger boot if you need it. If carrying passengers and luggage regularly is part of your routine, the A3 is the more sensible choice.
Driving Impressions
Audi A1 driving score: 4/5
Audi A3 driving score: 4/5
Both of these cars provide the refined and composed driving experience Audi is known for. The A1 feels nimble and light on its feet, making it well-suited to city driving, and its range of small petrol engines is responsive. While it may not be as outright fun as a MINI, it compensates with a more comfortable ride.
The A3 feels like a larger, more mature car on the road. The ride is firm but well-controlled, and it feels stable and quiet on the motorway, making it a great long-distance cruiser. It isn't as agile as a BMW 1 Series, but its overall blend of comfort and composure is impressive. Your choice here depends on your priorities: the A1’s agility for town, or the A3’s settled nature for the open road.
Technology and Equipment
Audi A1 technology and equipment score: 4/5
Audi A3 technology and equipment score: 4/5
Audi doesn’t skimp on technology in its smaller cars. The A1 comes as standard with a 10.3-inch digital driver's display and an 8.8-inch central touchscreen with smartphone mirroring. It’s a slick setup for a car of this size.
The A3 builds on this with a slightly larger 10.1-inch central screen and Audi’s 10.25-inch Virtual Cockpit as standard. The interface is sharp and easy to use, and the overall cabin quality feels a step up from the A1, with more soft-touch materials. Both cars are well-equipped, but the A3’s cabin has a more premium feel, which is reflected in its higher price.
Running Costs
Audi A1 running costs score: 3/5
Audi A3 running costs score: 3/5
Thanks to a range of efficient turbocharged engines, neither car should break the bank. The A1’s petrol engines can return respectable economy figures of around 45mpg. The A3 offers a wider choice, including economical diesels that can achieve over 60mpg and a plug-in hybrid (PHEV) model that offers a useful electric-only range for low-cost commuting.
As premium products, both cars command higher insurance and servicing costs than mainstream alternatives like a Ford Fiesta or Focus. However, they also hold their value well, which helps to offset the higher purchase price over the course of ownership. For the lowest running costs, the A3’s PHEV version is the one to go for, provided you can charge it at home.

The Verdict
Audi A1 Overall CarGurus rating: 4.3/5
Audi A3 Overall CarGurus rating: 4.4/5
This is an incredibly close contest between two accomplished premium hatchbacks. Both the A1 and A3 offer a desirable badge, high-quality interiors, and a comfortable, refined driving experience. Choosing between them largely comes down to your needs for space and your budget.
However, based on our comprehensive CarGurus data, the Audi A3 takes a narrow victory. Its slightly higher Overall CarGurus rating reflects its greater practicality, more spacious interior, and wider range of engine choices, including efficient diesel and plug-in hybrid options. It’s the better all-rounder and the more suitable car for small families or those who frequently travel long distances.
This doesn’t mean the A1 should be overlooked. If you don’t need the extra rear-seat space and want a compact car that feels genuinely upmarket and is easy to drive in town, the A1 is an excellent choice. But for its superior versatility and all-round ability, the Audi A3 is our winner.
