Trunk comparison: Audi A3 Sportback vs Tesla Model 3

Key Differences

The Tesla Model 3 offers a significantly longer cargo space: with the seats folded down it is 15 in (+26%) longer and with the front seats upright it is 11.8 in (+39%) longer than the Audi A3 Sportback.

In contrast, the Audi A3 Sportback has a significantly higher trunk opening and more interior height: the opening is 9.8 in (+48%) higher and the depth (loading edge to trunk floor) is 2 in (+45%) greater than in the Model 3. The loading edge height of both models is the same.

Smaller differences in width (Audi at the narrowest point +1.6 in / +4%, Tesla opening width +1.2 in / +3%) are below the 10% threshold and thus negligible from a user perspective.

Impact on Usability

The greater length of the Tesla allows for transporting longer items, both with folded seats and with the front seats upright. This makes the Model 3 better suited for long items like boards, skis, or furniture parts without having to dismantle seats extensively or resort to complex angle solutions.

The significantly higher trunk opening and greater depth of the A3 increase vertical usability and capacity for bulky, tall, or stackable cargo.

Tall boxes, plants, or bulky items are easier to load and unload in the Audi because the opening offers more space upwards and the interior is deeper accessible. Since the loading edge height is the same, lifting/loading does not differ between the two vehicles.

Because the width differences are small, they play only a minor role in daily usability: The slightly larger opening width of the Tesla can make it easier to insert wide parts initially, while the slightly larger narrowest interior width of the Audi can help when finally stowing slightly wider items.
