Trunk comparison: Mercedes Benz GLC vs Opel Astra Wagon
Key Differences
The most significant differences concern the vertical dimensions and the loading edge: The height of the trunk opening of the Opel Astra Sports Tourer is 3.5 in or 12% higher than that of the Mercedes‑GLC, allowing for more pass-through height.
The depth of the trunk (distance from loading edge to trunk floor) of the Opel is 5.5 in or 1300% greater — here there is a significantly deeper cargo area.
At the same time, the loading edge of the Mercedes‑GLC is 3.9 in or 16% higher above the ground than that of the Opel, meaning that with the GLC, heavier lifting from the ground is required when loading.
Other, smaller differences: The Opel has about 3.5 in (10%) more cargo length with the first row of seats upright and about 1.2 in (2%) more with the seats folded down.
The narrowest width of the trunk is 3.1 in (8%) greater in the GLC, and the width of the trunk opening is 1.2 in (3%) larger in the GLC — these values are under 10% and less significant.
Result for Usability
Due to the higher trunk opening and significantly greater depth, the Opel Astra Sports Tourer offers an advantage for tall or bulky cargo: bulky, tall items can be more easily passed through the opening, and the deeper cargo area increases usable volume for bulky or irregularly shaped loads.
Additionally, the loading edge on the Opel is lower, which makes lifting heavy items in from the ground easier.
However, the very deep cargo floor in the Opel has a downside: if the load lies deep in the well, heavy items must first be lifted up to the loading edge when removing them — this can make back-friendly handling more difficult.
The Mercedes‑GLC, with its higher loading edge, generally requires more lifting when loading from the ground but offers a flatter, more easily accessible cargo floor, so items on the floor are easier to reach.
Additionally, the interior at the narrowest point and the opening in the GLC are slightly wider, which facilitates loading wider items when width is critical.
Conclusion: For frequent transport of tall or bulky cargo and when maximum depth/total volume is important, the Opel is more practical. For easier access to the cargo floor and somewhat more usable width for items lying crosswise, the Mercedes‑GLC can be advantageous.
