Trunk comparison: Opel Grandland vs Seat Leon

Key Differences

Three clear differences stand out in the comparison: The Opel Grandland has a longer cargo space with the seats folded down: +7.9 in (≈13%) compared to the SEAT Leon.

The narrowest width in the trunk is significantly larger in the Grandland: +7.9 in (≈25%). Conversely, the trunk depth (loading edge to floor) is significantly greater in the SEAT Leon: +3.5 in (≈56%) than in the Grandland.

What are the practical implications?

These differences result in specific advantages and disadvantages in practice. Due to the greater length with folded seats and the significantly larger narrow width, the Grandland is clearly better suited for long and wide items (e.g., slats, furniture panels, skis, or larger boxes).

When the rear seats are folded down, more and wider cargo can be transported in the Grandland.

The SEAT Leon scores with the significantly greater trunk depth and an overall lower trunk floor (considering the loading edge height, the floor of the Leon is about 4.7 in lower in practice than in the Grandland).

This makes loading bulky or heavy items more ergonomic — less lifting height from road level into the cargo space — and offers more vertical space in the trunk for tall items in an upright position.

Smaller differences with minimal impact: with the first row of seats upright, the Grandland is only about +2.4 in (≈7%) longer; the opening height and width differ by only ≈0.4 in; the loading edge of the Grandland is ≈1.2 in higher.

These values are usually negligible in practice compared to the three differences mentioned above.

Conclusion: For transporting long or wide loads, the Opel Grandland is better suited. For easier lifting of heavy loads and more vertically usable space in the trunk, the SEAT Leon is the more practical choice.
