Trunk comparison: Peugeot 3008 vs VW Tiguan

Key Differences (highlighted: >10%)
Two differences stand out clearly from the data: The Peugeot 3008 has a 4.3 in (≈13%) longer trunk with the first row of seats upright than the VW Tiguan. Additionally, the trunk depth (measurement: loading edge → trunk floor) is 3.9 in (≈1000%) greater in the Peugeot.
All other mentioned deviations are below the 10% mark (e.g., Tiguan +3% with folded seats, Tiguan +7% opening width, Peugeot +5% opening height, Peugeot +8% loading edge height) or are equal (width at the narrowest point).
Implications for Usability
The longer trunk of the Peugeot with upright seats makes it more practical when traveling with rear seat passengers and still wanting to transport longer items (e.g., skis, long luggage, bulky boxes) in the trunk.
The significantly greater depth means more usable space between the loading edge and floor: this allows better stacking and more vertical volume for taller or bulky items.
At the same time, the Peugeot has a higher loading edge (+2.4 in), which makes lifting heavy loads into the vehicle somewhat more strenuous. The greater depth can partially compensate for this because items slide further down and thus lie more stably, but it may require more tilting when loading short, flat loads.
The Tiguan, on the other hand, offers slightly more length when all seats are folded down and a somewhat wider trunk opening.
However, these advantages are small (<10%) and rarely decisive in practice: they mainly help when loading very wide or flat items through the opening or transporting extremely long items with fully folded seats.
Conclusion: For regular transport of longer items with full seating and for better vertical cargo space, the Peugeot 3008 is clearly advantageous. Those who primarily rely on fully folded seats or a slightly wider opening have a minor advantage with the Tiguan, but overall it is less pronounced.
