The Audi A3 Sportback is spacious up front, has a roomy boot and is better than any alternatives for carrying two adults in the back – that said, it’s not so brilliant with three in the back

Passenger space

Interior space in the Audi A3 Sportback is generally good. Whether you’re tall or short you’ll find a comfortable driving position, and a front armrest is standard on all models so you can relax while driving on the motorway. All A3 Sportbacks also come with height adjustable seats for both front passengers.

You don’t get a raw deal if you’re sat in the back, either. There’s enough head and legroom, and the large rear windows avoid the claustrophobic feeling you get in the back of the Mercedes A-Class – in fact the Audi A3 Sportback is the best car of its type if you only ever carry two people in the back. It’s not all perfect though – there’s not much room for three adults in the rear because there’s a big bump in the floor that forces passengers into a game of footsie. An A-Class is actually better for space if you regularly carry adults in the back.

If you need to carry a child seat then rejoice – the Isofix child-seat anchors are clearly marked on both the outer rear seats and the wide-opening rear doors make it easy to pop the seat base into place. Only an SUV such as the Audi Q2 is fractionally easier because the higher seating positions means you needn’t stoop quite as much as you have to in the A3.

Storage space

There’s a decent amount of storage space in the Audi A3 Sportback. Each of the door bins is big enough to accommodate a two-litre drinks bottle, although they’re not quite as vast as those in the Mercedes A-Class. A two-litre bottle will also fit in the sizeable glove box and there are four full cup holders – two in the centre console and two in the rear armrest.

The front armrest on the centre console opens up to reveal even more storage and charging points for your phone. It also has a handy elasticated strap to hold smaller items in place.

All A3 models get comfy seats, and S Line models get fancy half-leather, half-suede ones that feel expensive

Boot space

The Audi A3 Sportback’s 380-litre boot is a useful square shape and has a wide opening making it easy to load large items.

The boot floor on all A3 Sportback models can be raised and lowered. With the boot floor in its lowest position you get the biggest boot volume, and with it raised there’s no boot lip to lift heavy objects over when loading. With the rear seats folded down the boot’s total capacity swells to 1,220 litres, which is big enough to fit a bike without having to remove a wheel.

Not only is the boot a useful shape, but it also has a handful of touches that help make life easier. There are a number of hooks and tether points so you can secure your loads – whether it be flat-pack furniture or your takeaway curry.
