Trunk comparison: BMW i4 vs Opel Grandland
Key Result
The BMW i4 offers slightly more cargo length: with the seats folded down it is 2.8 in (4%) longer, with the first row of seats upright 3.5 in (10%) longer — these are only small advantages in favor of the BMW. Significantly larger differences favoring the Opel Grandland concern the dimensions of the opening and the width: the Opel has

. Additionally, the depth from the loading edge to the trunk floor is
on the Opel, and the loading edge height above the road is
than on the BMW.
Impact on Usability
The wider dimensions and larger opening of the Opel clearly make it more practical for bulky or wide items (boxes, furniture parts, strollers, wide suitcases): with +15% more width at the narrowest points and at the opening, large parts can be more easily rotated and loaded. The 21% higher opening provides more vertical clearance for tall items. At the same time, the higher loading edge on the Opel (+11%) increases the lifting height required when loading — heavy items must be lifted higher, making loading less comfortable. The greater depth from the loading edge to the trunk floor (+60%) means the floor lies deeper than the loading edge; this provides more vertical storage space under the loading edge but can make sliding in flat items more difficult and also requires more strength for heavy loads because they must be lifted higher over the edge. The BMW scores with a lower loading edge (3.1 in lower) and an overall slightly lower trunk floor (about 0.8 in lower above the road), which makes lifting heavy items easier and improves ergonomics when loading. Its somewhat greater length (up to 3.5 in or 10%) helps when transporting longer items but is less relevant if width or opening height are limiting factors. Conclusion: For wide or tall cargo, the Opel Grandland is the better choice due to its opening and width; for frequent loading of heavy luggage or ergonomically easier lifting, the BMW i4 wins thanks to the lower loading edge and easier access.
