The new car is 58mm longer than its predecessor, making it 35mm longer than the current three-door. It also gets a 380-litre boot, which is in an increase of 10 litres over the old Sportback and 30 litres over the current three-door.
There are no surprises in terms of styling, with the changes limited to an extra pair of doors and a set of roof rails. It gets the same nose and gaping grille as the three-door, with Audi’s design language apparent throughout. Interior quality will be top-notch, too.
Spec and engine choice will follow the three-door, meaning there are two petrol and one diesel motor at launch. The mid-range 2.0-litre TDI diesel will be capable of 0-60mph in around 8.5 seconds while returning more than 60mpg average fuel economy. Buyers can choose between base-spec SE, mid-range Sport or flagship S line trims.
Specifying two extra doors on your new A3 will cost you £620, with prices starting at £19,825 for a 1.4 TFSI Sportback SE. A top-spec 1.8 TFSI Sportback S line will cost you £27,180 and all models should be in showrooms early next year.
