Trunk comparison: Audi Q3 vs Tesla Model 3

Loading Length and Depth

The Tesla Model 3 offers noticeably more loading length: with seats folded down, the Tesla's trunk is +8.3 in (13%) longer, and with the front seats upright, it is +6.7 in (19%) longer than the Audi Q3. Additionally, the depth from the loading edge to the trunk floor is +0.8 in (22%) greater in the Tesla.

This clearly makes the Tesla more suitable for longer items (e.g., long packages, skis, slats) and for an overall larger usable cargo depth, especially when seats are folded down.

Trunk Opening and Loading Edge

The Audi Q3 has a significantly higher opening: the height of the trunk opening is +10.2 in (50%) greater in the Audi. This facilitates loading tall or bulky items that need to fit through a larger opening.

On the other hand, the loading edge of the Audi is +3.1 in (12%) higher above the ground than the Tesla’s, so more lifting effort is required with the Audi — heavy loads are easier to lift in and out or slide in the Tesla.

Width and Limitations

The width of the trunk opening is +4.7 in (12%) larger in the Audi, which makes loading wider items easier.

The narrowest width inside the trunk is only slightly larger in the Audi (+2 in / 5%) and does not fall into the category of major differences; therefore, in practice, there is hardly a significant difference here.

Conclusion: Which Uses Are Preferred?

- If you frequently transport long loads (folded seats or long items with the rear seats upright), the Tesla Model 3 offers a clear advantage due to the longer loading area and greater depth.
- If you often need to load tall or bulky objects, or simply prefer a larger opening, the Audi Q3 is more practical because of the significantly higher trunk opening.
- For frequent loading and unloading of heavy items, the Tesla is more ergonomic due to the lower loading edge.
- For loading very wide parts, the wider trunk opening of the Audi is advantageous.
