Trunk comparison: Opel Corsa vs VW ID.3

Key Differences (>10%)
The VW ID.3 offers significantly more cargo length: With the seats folded down, the trunk of the ID.3 is 8.3 in (+16%) longer than that of the Opel Corsa; with the front seats upright, it is even 5.1 in (+20%) longer. The width of the trunk opening on the ID.3 is 3.9 in (+12%) larger than on the Corsa.
Conversely, the Opel Corsa has a greater trunk depth (loading edge to trunk floor) by 0.8 in (+13%) compared to the ID.3.
Impact on Usability
The longer cargo areas of the ID.3 (both with folded seats and with the rear bench upright) make it more practical for long items such as skis, furniture parts, or moving boxes and increase flexibility for weekend trips or transports.
The larger opening width of the ID.3 significantly eases loading bulky items — wide packages and furniture are easier to maneuver.
The greater trunk depth of the Opel Corsa means that the usable space immediately behind the loading edge is somewhat deeper. This can be advantageous when stacking boxes or using higher cargo volume in this area, but it does not match the overall length and width of the ID.3.
Other Differences (≤10%)
The height of the trunk opening of the ID.3 is 0.8 in (+3%) larger — practical for very tall items, though the effect is minor.
The loading edge of the ID.3 is 2.8 in (10%) higher above the road than the Corsa; this means slightly more lifting effort when loading, but it mainly affects heavy loads. The narrowest interior width differs by only 2 in (+5%) in favor of the ID.3 and has minimal impact in everyday use.
