Audi A5 Cabriolet (2017-present): dimensions and boot space

All the dimensions you need for the Audi A5 Cabriolet - including figures for width, length, height and boot size

The Audi A5 Cabriolet is a two-door convertible car that’s comfortable, stylish and easy to drive. It’s part of the A5 range, alongside the A5 Coupe, A5 Sportback and the S5 and RS5 models that bring extra performance with bigger engines.

There used to be an Audi S5 Cabriolet but when the range was updated in 2020 this version was killed off. That means in the most recent A5 Cabriolet range, the highest-performance version is the 45 TFSI petrol model.

The A5 Cabriolet features a canvas soft-top roof, which can be folded away at the touch of a button. It reduces boot space a bit when you do this, but it’s not by too much - you can read more about this below. Rivals include the BMW 4 Series Convertible and Mercedes C-Class Cabriolet, which are all of a similar size and also have four seats.

You can find out more about the Audi A5 Cabriolet and what it’s like in our full buyers' guide but here we’ll take a closer look at the car’s dimensions and boot space, plus some more technical aspects to help you decide if it’s right for you.

Audi A5 Cabriolet dimensions

Generally speaking, the Audi A5 Cabriolet is 4.7m long, 1.8m wide and 1.4m tall - you can see the exact dimensions in our table below. The A5 Cabriolet is pretty similar in size to the A5 Coupe, as both have two doors - the Sportback model is larger with two extra passenger doors and a hatchback, and is more spacious inside as a result.

As a comparison, the BMW 4 Series Convertible is 4.8m long, 1.9m wide and 1.4m tall, but those are the rounded-up figures - it’s even closer in size than that, as the differences are a matter of millimetres.

The rear seats in the A5 Cabriolet are tight for adults, but when you compare them to its rivals, the Audi is actually pretty practical. There’s more space in the Audi than in the BMW or Mercedes, but all three cars are designed for occasional passengers rather than daily family duties.

Audi A5 Cabriolet boot space

The A5 Cabriolet has a 370-litre boot, so it’s significantly less roomy than the 465-litre space in the A5 Sportback. This is expected in a convertible car, though, as the roof mechanism takes up extra space. Also, when the roof is folded away, the boot space reduces by about 60 litres - so you need to be careful about putting too much in the boot before you try to lower the roof.

The boot door is fairly small so the opening isn’t great for bigger items, but it’s easily forgiven in a convertible car. The latest BMW 4 Series Convertible has a little more space, at 385 litres, but it’s not by a huge amount.

Audi A5 Cabriolet towing capacity

The Audi A5 Cabriolet is a pretty unlikely tow car, but if you fancy taking a caravan to the coast and enjoying some roof-down driving when you get there, it’s good to know that you can tow at least 1,700kg in even the entry-level model. This is a high figure for this type of car and gets higher still with the more powerful engine options.

Choose a more powerful 40 TDI model with the 2.0-litre diesel engine and that goes up to 2,000kg. The 45 TFSI, the most powerful engine you can get in the current A5 Cabriolet, can tow a braked trailer of up to 1,900kg, meanwhile.

Audi A5 Cabriolet weight

A car’s weight makes a big difference when it comes to performance and fuel economy, all other things being equal. A lighter car will also generally be more fun to drive. You can gauge a car’s kerb weight figure, which includes all the fluids in the engine, a tank of fuel and (in most cases) a 75kg driver, to find out how much it weighs.

The A5 Cabriolet is available with a range of engines, but since they’re all relatively small units that won’t change the weight too much. The addition of four-wheel-drive on certain models will, however increase the weight - so the A5 range does have a spread of weights that goes from 1,665-1,770kg. This means it’s heavier than an equivalent A5 Coupe, due to the extra strengthening needed underneath to cater for the lack of a fixed roof, along with the weight of the folding mechanism.
