Trunk comparison: Opel Astra Wagon vs Seat Leon

Main Differences
The Opel Astra Wagon offers a longer trunk: with the seats folded down it is +6.7 in (11%) longer, and with the front seats upright even +9.4 in (29%) longer than the SEAT Leon. Additionally, the trunk width at the narrowest point in the Astra is +11 in (35%) larger.
In contrast, the SEAT Leon has a significantly greater depth between the loading edge and trunk floor (+9.1 in / 1150%) and a higher loading edge above the road (+6.3 in / 27%).
Smaller differences under 10% include the slightly higher opening height (+0.8 in / 3%) and the marginally wider trunk opening in the Leon (+1.6 in / 4%).
Impact on Usability
For everyday use and transporting large, wide, or long items, the Astra Wagon is clearly more practical: the greater interior length with seats folded and upright as well as the significantly larger narrow point width allow for wider suitcases, furniture parts, or sports equipment without complicated pushing or turning.
This makes the Astra better suited for families with luggage, DIY or furniture transport, and anyone who regularly needs to carry bulky cargo.
The SEAT Leon offers advantages of a different kind: the much greater depth between the loading edge and trunk floor means the cargo floor sits lower — this creates more usable volume below the loading edge and is suitable for stacking or hiding cargo.
However, the Leon’s loading edge is significantly higher, which makes lifting heavy items into the trunk more difficult. Small advantages like the slightly higher opening height and the somewhat wider opening only marginally ease loading very tall or bulky items.
In summary: Those who frequently transport wide or long cargo and prefer easy access benefit more from the Opel Astra Wagon. Those who value a lower positioned cargo volume and can live with a higher loading edge will find an alternative solution in the SEAT Leon.
