Trunk comparison: Audi A4 Avant vs Tesla Model Y

Comparison of trunk dimensions for the Audi A4 Avant and Tesla Model Y

Key Differences

In short: The Tesla Model Y offers slightly more usable loading length, while the Audi A4 Avant scores with vertical opening and cargo well geometry. Specifically, the relevant values are:

Loading length with rear seats folded down: Tesla +4.3 in (6%) — not significant (>10%).
Loading length with front seats upright: Tesla +2.4 in (6%) — not significant.
Height of the trunk opening: Audi +6.3 in (23%) — significantly larger.
Depth of the trunk (distance from loading edge → trunk floor): Audi +2 in (400%) — significantly deeper/differently shaped cargo well.
Loading edge height above road: Tesla +2.8 in (11%) — noticeably higher.
Width at the narrowest point: Audi +1.6 in (4%) — negligible.
Width of the trunk opening: Audi +0.4 in (1%) — negligible.

Impact on Usability

Height of the trunk opening (Audi significantly higher): The 6.3 in higher opening allows taller items to be loaded vertically more easily in the Audi. This facilitates placing crates, plants, or furniture parts that require a certain height; in the Tesla, the roofline may limit the accommodation of tall cargo.

Depth of the cargo well (Audi significantly deeper): The greater depth means the Audi has a more pronounced cargo well or more space below the loading edge. This helps secure smaller items against shifting and sometimes allows cargo to sink deeper without exceeding the roofline.

In practice, this means better stacking and more security for loose cargo; the Tesla’s surface is flatter/smoother, which can be advantageous for very long, flat items but offers less protection for small parts.

Loading edge height (Tesla higher): The 2.8 in higher loading edge in the Tesla makes lifting heavy items into the trunk more strenuous and less ergonomic. The Audi, with its lower loading edge, is more comfortable when loading suitcases, groceries, or heavy parts.

When each vehicle makes more sense: For very long cargo (folded seats), the Tesla Model Y has an advantage due to slightly greater loading lengths.

For tall, bulky, or frequently heavy lifting cargo, the Audi A4 Avant is better suited thanks to its higher opening, deeper cargo well, and lower loading edge. Width differences are so minor that they hardly affect everyday usability.
