Trunk comparison: VW Golf Wagon (Mk5) vs VW Tiguan

Key Differences
Three differences stand out clearly from the data: The trunk of the VW Golf 5 is +6.7 in (19%) longer with the first row of seats upright than that of the VW Tiguan. The trunk depth (distance from loading edge → trunk floor) of the Golf 5 is significantly larger at +1.6 in (400%).
Additionally, the loading edge of the VW Tiguan sits +3.9 in (16%) higher above the road than that of the Golf. All other differences (e.g., widths or opening height) are under 10% and thus comparatively small.
Impact on Usability
The 19% longer cargo area of the Golf with seats upright means more usable storage space in everyday use without folding the seats — advantageous for suitcases, groceries, or longer items that need to be transported regularly.
The greater depth of the Golf (given as +1.6 in / 400%) indicates a deeper trunk floor relative to the loading edge; this creates more space in the lower trunk area for flat-stacked or smaller items but can make sliding very heavy loads directly over the edge more difficult if the loading edge is low at the same time.
The 16% higher loading edge of the Tiguan results in noticeably more lifting effort when loading — ergonomically less favorable for heavy items than the Golf.
At the same time, the higher loading edge corresponds to the typical SUV design (more ground clearance), which can be advantageous when driving on uneven terrain but is rather a disadvantage for frequent lifting of luggage or groceries.
Conclusion: For regular loading of heavy or bulky items with low lifting effort and more usable length without folding seats, the Golf 5 is more favorable. The Tiguan offers advantages off paved roads due to the higher loading edge and SUV concept but has a disadvantage in ergonomic loading.
