As a small upmarket soft-top with four seats, the Audi A3 Cabriolet is quite a rare type of car. It’s larger than two-seat open-top sports cars such as the Mazda MX-5 and the more exotic and expensive Porsche 718 Boxster, but not as roomy as plush four-seater convertible rivals like the Audi A5 Cabriolet, BMW 4 Series Convertible and Mercedes E-Class Cabriolet.

The closest rivals for the A3 Cabriolet are the BMW 2 Series Convertible and the VW Golf Cabriolet, although the latter was only sold up until 2016. 

The Audi A3 Cabriolet sold from 2014-2020 is the second version of the A3 Cabriolet. There was an earlier version sold between 2009 and 2013, but this was based on an older model. It featured slightly stumpy-looking styling and a much smaller boot at 260 litres compared with 320 litres in the one featured here.

You can find examples of this version of the newer Audi A3 Cabriolet from £261 per month with PCP finance. Read on for more details about its dimensions and boot space.


Audi A3 Cabriolet dimensions

The 4.4-metre-long Audi A3 Cabriolet is a touch longer than the A3 Sportback hatchback introduced in 2020, and longer than its contemporary three-door hatchback (2013-2020) A3 equivalent (by 20 centimetres). It’s also 10 centimetres longer than the five-door Sportback hatchback from the same era. It’s also 1.8 metres wide, which increases to two metres once you add in the door mirrors.

This compact width means that the A3 Cabriolet should be simple to drive in tricky car parks or narrow city streets - it’s certainly more wieldy in these sorts of conditions than a larger convertible such as the Audi A5 Cabriolet.

The 1.4-metre height of the A3 Cabriolet makes it a couple of centimetres lower than the hatchback versions. This helps make it look suitably sleek with the roof in place, but does compromise headroom a little, especially for passengers in the rear seats. This is not really a car for four people when it comes to longer journeys, though younger children should be fine.

Audi A3 Cabriolet boot space

With convertible cars, it’s inevitable that some space has to be saved to fold the roof away. And even though the A3 Cabriolet features a folding fabric hood, which is more compact than an equivalent folding metal or glass roof, it still takes up some interior room.

In part this is soaked up by reducing the amount of space in the rear seats, but in part it is also the boot space that takes a hit. The A3 Cabriolet provides a reasonable 320 litres, but that is still 60 litres below what you'd get in the A3 Sportback, despite the longer bodywork of the A3 Cabriolet.

Boot capacity probably isn’t a number-one priority if you’re considering a convertible, but the A3 Cabriolet is still more practical than many options. Its boot space also outshines the 280 litres that you get in the BMW 2 Series Convertible.

Audi A3 Cabriolet towing capacity

The A3 Cabriolet is not the sort of car you’d usually expect to tow with, but it is rated for towing, just as with the conventional A3 hatchback, with a rating of 1,500kg to 1,800kg for a braked trailer, which is reasonably strong.

Given that it is not recommended to tow anything that weighs more than your car’s kerb weight, however, in practical terms you’ll be limited by this figure, since the kerbweight of the Audi A3 Cabriolet is anything between 1,380kg and 1,570kg depending on the model.

If you need an effective tow car, and fancy and Audi, something larger and heavier such as the Audi A6, or Q5 or Q7 SUVs would make more sense, as these can cope with heavier trailers or caravans.

Kerb weight figures show heavy a car is likely to be in the real world. This takes account of the fluids in the engine, a tank of fuel plus an extra 75kg, which represents the weight of a typical driver.

Specific weights for any range of cars vary depending upon the precise specifications available. Four-wheel drive and automatic gearboxes can add a substantial amount of weight, for example, as can the battery packs required in plug-in hybrid cars. In general, the heavier a car is, the less agile it will be and the more fuel it will burn.

Convertible cars typically weigh more than hatchback or saloon equivalents, as extra strengthening materials are required to keep the body rigid. In the case of this generation of Audi A3 Cabriolet, you can expect one to weigh between 1,380kg and 1,570kg, depending on the model. That's slightly on the high side for a car of this size, due to the additional weight of the folding roof setup.
