Trunk comparison: Audi Q5 vs Opel Astra Wagon

Key Differences

The clearest advantage lies with the Opel Astra: The depth of the trunk (distance from loading edge → trunk floor) is 2.4 in or +75% greater in the Astra than in the Audi Q5. Additionally, the loading edge of the Q5 sits 5.1 in or +21% higher above the road than the Astra.

Combined, this means the trunk floor of the Astra is about 7.5 in lower than that of the Q5.

Other Differences (less than 10%)

The Astra also offers a longer trunk: +4.7 in (7%) with the seats folded down and +2.8 in (7%) with the first row upright. The height of the trunk opening is 2.4 in (8%) larger in the Astra. The Audi has a 0.4 in (1%) greater width at the narrowest point and a 2.4 in (6%) wider trunk opening.

Impact on Usability

Due to the significantly deeper trunk width and the lower loading edge, the Astra is noticeably more practical for loading and unloading heavy or bulky items: less lifting effort, easier sliding in, and a lower loading height relative to the road.

This makes the Astra advantageous for regular transport of heavy boxes, equipment, or for users who want to reduce physical strain when loading.

The Audi Q5, on the other hand, offers slightly more width at the narrowest point and a somewhat larger opening, which slightly favors loading very wide items. However, these differences are minor and hardly noticeable in everyday use compared to the significantly lower floor and loading edge advantage of the Astra.

Conclusion

For frequent loading of heavy or bulky goods, the Opel Astra Sports Tourer is the more practical choice due to the significantly lower loading edge and deeper trunk floor. The Audi Q5 offers only marginal advantages in width and opening but remains at a disadvantage in handling heavier loads compared to the Astra.
