Trunk comparison: Volvo XC40 vs VW Golf Wagon (Mk5)

Key Differences
The most relevant differences lie in three points: The VW Golf 5 has a 5.5 in (≈15%) longer cargo space with the first row of seats upright than the Volvo XC40. Additionally, the measured depth of the trunk (loading edge to trunk floor) is 2 in (+400%) greater in the VW Golf 5. In contrast, the loading edge of the Volvo XC40 is 4.3 in (≈17%) higher above the road than the Golf.
The other measurements (lengths with folded seats, opening height, widths) differ only by 1–5% and are practically negligible.
Impact on Usability
Due to the 15% longer cargo space with the rear seats upright, the VW Golf 5 is better suited for longer items (e.g., boards, skis, long boxes) without needing to fold down seats.
The significantly greater trunk depth in the Golf creates more usable volume below the loading edge — this is advantageous when items need to lie low in the cargo area or when more storage space is needed for bulky but low loads.
The higher loading edge of the Volvo XC40 makes lifting heavy or bulky items into the interior more strenuous; at the same time, the load sits somewhat higher above the road in the Volvo, which should be considered when loading and unloading and when rolling luggage.
For users who frequently lift heavy items or work a lot with rolling suitcases and bulky goods, the lower loading edge height and greater depth of the Golf are more practical.
In summary: For longer and lower-lying cargo, the VW Golf 5 has the advantage. The Volvo XC40 shows only minor differences in the other dimensions, which usually do not cause noticeable limitations in everyday use, except for the higher loading edge, which makes loading somewhat more difficult.
