Trunk comparison: BMW X5 vs VW Golf Wagon

Main Differences (Highly Relevant)
Two clear differences stand out from the data: The VW Golf Wagon has a significantly greater trunk depth (distance from loading edge → trunk floor) than the BMW X5, namely +3.9 in (≈1000 %). Additionally, the loading edge of the BMW X5 is noticeably higher above the road than that of the VW, namely +7.1 in (≈30 %).
What practical consequences arise from this?
VW Golf Wagon – deeper loading area: The greater depth means that the Golf Wagon has a lower trunk area. Practically, this means: bulky or tall items can be better stored below the tailgate line, overall more usable vertical height in the cargo space without exceeding the loading edge.
This is advantageous for transporting crates, toolboxes, or shopping bags. However, a lower floor can make reaching into the floor area somewhat less comfortable.
BMW X5 – higher loading edge: The significantly higher loading edge of the X5 makes lifting heavy loads in and out less comfortable, especially with heavy items.
For regular loading of bulky or heavy luggage, this is a disadvantage. A higher loading edge can offer advantages for off-road use or a higher seating position in terms of ground clearance, but reduces convenience when loading in everyday use.
Other, less relevant differences
Other differences are smaller than 10% and have less noticeable practical impact: cargo length with folded seats (+1 % VW), cargo length with the first row upright (+5 % VW), height of the trunk opening (+3 % BMW), as well as trunk width at the narrowest point and opening width (+9 % BMW each).
These values can be noticeable in individual cases (e.g., when loading very wide items), but overall are secondary compared to the points mentioned above.
Conclusion
For users who frequently load heavy or large items, the VW Golf Wagon is more comfortable in everyday use due to the deeper loading area and lower loading edge.
Those who prefer higher ground clearance or a higher vehicle position and less often lift heavy loads can live with the higher loading edge of the BMW X5. Smaller length and width differences are usually not decisive in everyday life.
