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

Learn more about the Audi A5 and S5 Sportback dimensions - including width, length, height and boot size figures

The Audi A5 Sportback is a five-door coupe that’s designed to offer the stylish looks of the A5 Coupe but with two extra doors and a bit more space in the rear to accommodate families, along with a handy hatchback for easy access to the boot. The S5 Sportback is the same body shape, but it has a more powerful engine and sportier suspension for sharper handling around corners - so despite the different name, it’s very similar and we’ve included both in this article about their dimensions and boot space.

There was an update to the range in 2020, which brought some fairly minor cosmetic changes and some differences in the equipment offered. This update didn’t change the fundamentals of the car, though, so it’s mostly pretty similar to the pre-2020 version that came out in 2017.

The A5 Sportback is recommended for those who want to drive a stylish car and love the looks of the A5 range, but need the extra rear doors and more practical boot shape and access of the Sportback model. The S5 version offers a high-performance version that’s still good for everyday driving.

You’ll find everything you need to know about the dimensions and boot space of the A5 and S5 Sportback below, including details on each version and brief comparisons to rival models. Keep reading to find out if it's the car for you.

Audi A5 Sportback dimensions

The A5 Sportback is 4.8m long, 1.8m wide and 1.4m tall, which means it’s slightly longer than the A5 Coupe but still slightly shorter than the BMW 4 Series Gran Coupe, which is a few millimetres longer but still 4.8m long when rounded-up.

The A5 Sportback has rear doors and is longer than the A5 Coupe so it’s much more practical and can actually carry two rear passengers in relative comfort. The A5 still isn’t as roomy as the A4 saloon, though you do get greater access to the boot, as the rear windscreen raises with the boot, unlike in the A4. For the greatest practicality, however, the A4 Avant estate offers plenty of passenger and luggage room, plus a hatchback opening.

The S5 high-performance model is slightly longer and lower than the A5 version because of the body kit and lowered suspension, but it’s pretty much the same size overall.

Audi A5 Sportback boot space

The A5 Sportback has a 465-litre boot, which is larger than the A5 Coupe’s boot but not as big as the BMW 4 Series Gran Coupe, which has 470 litres available (and 480 litres in the pre-2021 version). The S5 model has a little bit less, at 430 litres, though it’s hard to notice the difference in the real world.

Fold the seats down and there are 1,280 litres of space in the A5 Sportback and 1,245 litres in the S5 Sportback. This is a little less than in the 4 Series but it’s not by so much that it will make a big difference to most drivers.

Along with the folding seats, the Sportback model has a larger boot opening than the A5 Coupe, which means it’s easier to load in larger items. It’s much more practical as a result.

Audi A5 Sportback towing capacity

You can tow up to 2,000kg in the A5 and 2,100kg in the S5 Sportback, though lower-powered petrol models are limited to 1,700kg. This is still quite impressive for a sporty-looking coupe, and could be useful for a small number of buyers.

You can buy the A5 Sportback with four-wheel-drive, which could be useful for towing - especially as this option is typically fitted alongside the more powerful engine options - but the main thing to consider is that the higher-powered diesels are best for pulling power.

Audi A5 Sportback weight

A car’s weight affects many aspects of the driving experience. Lighter cars are more fuel efficient, better to drive and faster if all other factors are equal. To assess the real-world weight of a car you can check the kerb weight figure, which includes all the fluids in the engine, a tank of fuel and (in most cases) a 75kg driver.

The A5 and S5 Sportback range is fairly broad and there are both petrol and diesel engines as well as the option of four-wheel-drive - which adds weight - although all models come with an automatic gearbox. This means the weight ranges from 1,510kg to more than 1,800kg in the S5 model, which has a larger six-cylinder engine.
