Trunk comparison: Audi Q3 vs Opel Grandland

Most Important Difference (>10%)

The most noticeable difference is in the depth of the trunk (measured from the loading edge to the trunk floor): The Opel Grandland offers +2.8 in or +78% more here than the Audi Q3. This is the only value with a double-digit percentage difference and thus the biggest practical difference between the two models.

Impact on usability: Due to the significantly greater depth, the Grandland has more usable interior edge-to-floor depth. That means

• more space for tall or bulky items behind the loading edge, especially with the seats folded down;
• better stacking of items without them protruding over the loading edge;
• more volume in the lower area of the cargo space, which is noticeable in practice with crates, toolboxes, or large shopping bags.

Other, Smaller Differences

The remaining differences are much smaller (one to four percent) and have less impact on everyday usability:

• Opel Grandland has a trunk that is 1.2 in (2%) longer in the fully folded state than the Audi Q3 — an advantage when transporting long items with folded seats.
• The Audi Q3 has a trunk that is 0.4 in (1%) longer with the first row of seats upright — practically hardly noticeable.
• The height of the trunk opening is 1.2 in (4%) larger on the Opel — making it easier to load tall items.
• The loading edge of the Opel is 1.2 in (4%) higher above the road — this increases the loading volume above the road but makes lifting heavy loads slightly more difficult.
• The width at the narrowest point is 0.4 in (1%) larger on the Opel — negligible.
• The width of the trunk opening is 1.6 in (4%) larger on the Audi — advantageous when loading wide items.

Conclusion on Usability

For users who frequently transport tall or box-shaped loads or need a lot of storage space in the lower trunk area, the Opel Grandland is clearly advantageous due to the significantly greater depth.

Those who often load very wide items or value a wider opening benefit more from the Audi Q3. The slightly higher loading edge of the Grandland increases the lifting effort when loading heavy items but is partially offset by the larger interior depth and the somewhat higher opening.
