Trunk comparison: BMW X4 vs Opel Grandland

Key Differences

With the first row of seats upright, the trunk of the BMW X4 is 5.1 in (+15%) longer than that of the Opel Grandland. The trunk opening of the Opel Grandland is 4.3 in (+16%) higher than that of the BMW X4. The depth of the trunk (loading edge → trunk floor) is 3.1 in (+100%) greater in the Opel Grandland compared to the BMW X4.

Other Differences (less than 10%)

When all seats are folded down, the BMW X4 is only 1.2 in (+2%) longer. The loading edge of the BMW X4 is 0.4 in (+1%) higher above the ground.

The narrowest trunk width is 0.4 in (+1%) greater in the Opel, and the opening width is 2 in (+5%) greater in the Opel. These differences are minor and often negligible in practical use.

Implications for Usability

The longer cargo floor of the BMW X4 with the first row upright makes it better suited for everyday use with long, flat items without folding the seats (e.g., sports equipment, long packages). The other length differences are marginal.

The Opel Grandland offers more vertical space due to the significantly higher opening and much greater depth. This facilitates loading tall or bulky items (boxes, suitcases, strollers) and provides more usable volume below the loading edge.

However, the greater depth also means heavy items must be lifted further into the vehicle or lowered deeper, which can affect handling when loading.

Conclusion

Those who regularly transport long items will benefit more from the BMW X4. Those who more often carry tall or very bulky loads will find the Opel Grandland more practical due to the higher opening and deeper cargo floor. Smaller differences in width and loading edge height are usually insignificant in daily use.
