The Audi A1 is the smallest in Audi’s range of cars - but that doesn’t stop it from being upmarket. The interior is still as stylish and as well put together as you’d expect from a premium brand like Audi, plus, it’s a good time to buy one because a new model  is just on the horizon.

Its main rivals are the Volkswagen Polo (from which it shares many mechanical parts), the Seat Ibiza, and Ford Fiesta. The Audi is generally more expensive than these cars, but also has more equipment, and more varieties of engine.

Read more about the A1 with our Audi A1 buying guide or check out our rundown of the dimensions below.

Audi A1 dimensions: exterior

On all exterior measures the Audi A1 is no bigger than average, but it has small side mirrors, so when you take them into account, it's actually narrower than average. That’s good to know when you’re manoeuvring in a tight parking space. The Audi A1 is lower than average, too, so it’s a doddle to wash the roof.

The wheelbase is the distance between the front and rear wheels, which usually gives a good indication of the amount of interior space.

Audi A1 boot space

Boot space is smaller than average, seats up or down. Although there is room for a few bags of shopping, a Polo has slightly more space on both measures.

If you fold the back seats down, there's a relatively large and wide area for luggage, which makes it useful for bulkier items, even if the overall amount of space is again less than in most rivals.

Bear in mind, though, that the sporty version, called the S1, has a much smaller boot because it has extra mechanical equipment for its four-wheel drive system.

Audi A1 dimensions: interior

Its design makes the Audi A1 look particularly small, but there's actually more space headroom inside than a Mini Hatchback. There’s enough legroom in the front for all but the tallest occupants too. On the other hand, the rear is a bit of a squeeze, and more so in sportier versions with bucket seats that curve around you.

Worth remembering is that the Audi A1 has only two rear seat belts as standard.

Audi A1 towing capacity

Being a lightweight car with a choice of small engines, the Audi 1 is no tow truck. The most you'll be able to pull is 1200kg, but some models have a lower limit. Given the car's small size, you are unlikely to want to venture that high, or even use the A1 as a tow car in the first place.

Audi A1 weight

The kerbweight figure is the weight of the car with a full tank of fuel and an additional 75kg representing the driver. Vehicle weight is a big influence on fuel consumption and the agility of the car in corners.

As a supermini, the Audi A1 is reasonably light and generally no heavier or lighter than a Mini Hatchback. On the other hand, it’s worth noting that the lightest versions of the Peugeot 208, a rival model, tip the scales at less than 1000kg.

Audi A1 fuel tank

The Audi A1’s fuel tank isn't very big at 45 litres (9.9 gallons) but that’s before you consider the model’s fuel consumption.
The most frugal version, the 1.6 TDI, has an official fuel economy figure of up to 76.3mpg. Even accounting for the typically large discrepancy between official and real-world figures, you should easily be able to manage 500 miles on a single tank.
The most frugal petrol, the 1.0 TFSI, should manage over 450 miles - more than 500 with some gentle driving. Given the higher cost of diesel versions, if you’re a low mileage driver it might be worth considering buying a petrol-powered A1.
