Trunk comparison: Audi Q5 vs Mercedes Benz GLB

Key Data

With the first row of seats upright, the Audi Q5 and Mercedes-Benz GLB have the same trunk length. When the seats are folded down, the GLB is 4.3 in longer (≈7%).

The loading edge of the Audi Q5 sits 0.8 in higher above the road than the GLB (≈3%). The narrowest trunk width is 0.8 in larger in the GLB (≈2%), while the width of the trunk opening is 2.8 in larger in the Audi Q5 (≈7%).

Highlighted Differences (>10%)

The trunk opening of the GLB is 3.5 in higher (≈11%). This provides significantly more vertical clearance when loading.

The depth of the trunk (loading edge → trunk floor) is 1.6 in greater in the GLB (≈50%). This results in more usable height/volume inside below the opening.

Implications for Usability

Thanks to the higher opening and significantly greater depth, the GLB is better suited for taller or bulky items (e.g., large boxes, suitcases, bulky furniture parts).

The higher opening makes loading and unloading standing or bulky objects easier, while the greater depth increases usable volume and allows for deeper placement of luggage.

The GLB also has an 4.3 in longer loading area with folded seats, which better accommodates longer items — although the difference is moderate (≈7%).

The Audi Q5 scores with a wider opening (+2.8 in), which facilitates maneuvering wider items inside. For very wide but not particularly tall cargo, the Q5 is therefore more practical. The loading edge of the GLB is somewhat lower, which, combined with the greater depth, makes handling heavy loads easier overall.

Practical Recommendations

If you frequently transport tall or bulky cargo (tall boxes, larger suitcases, bulky stacks), the GLB is more advantageous. If you often need to load very wide items through the opening, the Audi Q5 offers a smaller advantage.
