Trunk comparison: Mazda Mazda CX-5 vs Opel Astra Wagon

Key Differences

The most noticeable difference concerns the depth of the load floor: the depth of the trunk (loading edge to trunk floor) of the Opel Astra Sports Tourer is 3.5 in or 180% larger than that of the Mazda CX-5. Another significant difference is the loading edge height: the loading edge of the Mazda CX-5 is 5.9 in or 25% higher above the road than that of the Opel.

Implications for Usability

Taken together, these two differences make the Opel noticeably more practical in everyday use for loading and unloading heavy or bulky items.

The greater depth means the Opel has a deeper cargo area, thus more usable vertical space immediately behind the loading edge — which is advantageous for bulky, upright, or low-lying luggage.

The lower loading edge of the Opel reduces the effort required to lift heavy loads into the trunk and makes it easier to roll luggage, strollers, or shopping bags in and out.

In the Mazda, the higher loading edge results in more leverage effort when loading, especially with heavy loads; the shallower cargo depth also reduces the usable interior height directly behind the loading edge.

This makes the CX-5 less comfortable in daily use for frequent lifting of heavy or awkward items, although it is slightly wider at the narrowest point of the trunk.

Other, Smaller Differences

The trunk length is slightly larger in the Opel (+3.1 in / 5% with seats folded; +2.4 in / 6% with the first row upright). The height of the trunk opening is 2.4 in (8%) greater in the Opel, while the width of the trunk opening is practically identical (+0.4 in in favor of Opel).

The width at the narrowest point is 1.2 in (3%) larger in the Mazda. However, these differences are small and affect everyday usability much less than the depth and loading edge height.
