Trunk comparison: BMW X5 vs Toyota Corolla Wagon
Key Differences
With the rear seats folded down, the trunk lengths of both models are the same.
However, three differences over 10% stand out: The trunk depth (loading edge to trunk floor) is 2.8 in (+700%) greater in the Toyota Corolla Touring Sports than in the BMW X5. The loading edge of the BMW X5 is 5.9 in (+23%) higher above the ground than that of the Corolla.
And the narrowest width of the trunk is 5.9 in (+16%) larger in the BMW X5 than in the Corolla. All other measured dimensions (trunk length with first row seats upright +0.8 in/2%, height of the trunk opening +2 in/7%, width of the trunk opening +2.4 in/6%) are under 10% difference and comparatively insignificant.
Impact on Usability
The significantly greater trunk depth of the Corolla means that the interior space below the loading edge extends deeper. Practically, this means more "recess" for storing taller or less visible cargo and better possibilities to stack or hide items deeper.
Disadvantages can include more difficult access to the rear area and somewhat less convenient handling of long, flat items that need to be lifted over the loading edge.
The higher loading edge of the BMW X5 makes lifting heavy loads overall more strenuous—especially with boxes or heavy luggage.
On the other hand, the advantage is that with a higher loading edge, the cargo is easier to reach at trunk height when the tailgate is open (e.g., for side loading), and the ground clearance can generally be greater.
The greater narrow width in the X5 specifically means more room for wide items and more flexible loading without needing to shorten plywood sheets or built-in components.
Combined with the higher loading edge, the X5 offers a more practical, wider cargo area overall, which is especially suitable for bulky, wide loads. For deeper, concealed stacking or hiding luggage, the Corolla configuration is more advantageous.
Conclusion: The BMW X5 offers a wider, higher-positioned loading surface—better for wide, bulky items but with more lifting effort. The Corolla Touring Sports offers a significantly deeper cargo well—better for deeper or concealed stacking, but with narrower width and a lower loading edge.
