Audi A3 Sportback Boot Size: 380 Litres — The Premium Compact With the Narrowest Aperture

The Audi A3 Sportback (8Y) offers 380 litres but a 93 cm aperture width is the narrowest in the premium compact class. Full dimensions and luggage fit guide for rental travellers.


The Audi A3 Sportback (8Y, 2020–present) is one of the most common premium compact rentals in Europe. Its 380L boot is competitive, but the 93 cm aperture width is the tightest in the premium compact segment — narrower than the Mercedes A-Class (94 cm) and BMW 1 Series (approximately 100 cm). For most travellers with standard luggage this won't be an issue; it becomes relevant when you're loading wide items or trying to slide two bags in side by side.

Audi A3 Sportback Boot Dimensions (8Y, 2020–present)

MeasurementValue
Boot volume380 litres
Floor width99 cm
Load depth60 cm
Internal height64 cm
Aperture width93 cm
Aperture height68 cm

The 64 cm internal height means medium check-in suitcases (66 cm) will not stand fully upright — they lean slightly or load flat. The 68 cm aperture height is comfortable for bags up to 66 cm tall; taller bags need to be tilted on entry. The practical loading experience is comparable to a well-specced small hatch, which is broadly what the A3 is under the premium badge.

A3 Sedan vs. A3 Sportback for Luggage

Some rental fleets carry the A3 sedan (A3 Limousine) rather than the Sportback. The sedan has a larger quoted volume (425L) but a much more restrictive aperture — similar to the BMW 3 Series sedan problem. For luggage ease, always request the Sportback over the sedan if your company gives you the choice.
