Trunk comparison: Opel Astra Wagon vs Seat Ibiza

Key Differences

The Opel Astra Sports Tourer offers a cargo length that is +14.6 in (26%) longer than the SEAT Ibiza when folding down the rear seats. With the front seats upright, the advantage is even greater: the Astra has a cargo length that is +13.4 in (50%) longer.

The width of the trunk opening is +7.5 in (22%) larger in the Astra, while the narrowest interior width differs by only 1.2 in (≈3%) in favor of the Astra.

The depth of the trunk (from loading edge to floor) is +2 in (36%) greater in the SEAT Ibiza, and the loading edge is +3.1 in (13%) higher above the ground. The height of the trunk opening differs by only 1.2 in (4%) in favor of the Astra.

What are the practical implications of these differences?

The significantly longer cargo length of the Astra—both with folded seats and with the seat row upright—makes it clearly more suitable for transporting long items (e.g., furniture, slats, bicycles with folded seats) and for users who regularly carry larger or longer loads.

The wider trunk opening makes loading bulky or wide items much easier.

The SEAT Ibiza offers more vertical storage space below the loading edge due to the greater trunk depth. This can be useful for storing taller items inside the trunk or for using the space more efficiently when height is more important than length.

However, the higher loading edge in the Ibiza makes lifting heavy loads into the trunk more strenuous and loading bulky, heavy items less practical.

In practice, this means: Those who frequently transport long or wide items or often travel fully loaded (families, tradespeople, athletes) will find the Opel Astra Sports Tourer to be the better, easier-to-use solution.

Those who mainly drive in the city, rarely load long items, and want to benefit from a somewhat deeper cargo floor (with a compact exterior) can manage with the SEAT Ibiza—but must accept a higher loading edge and less cargo length.
