Trunk comparison: Skoda Karoq vs VW ID.3

Key Differences
Two differences stand out clearly from the measured data: The height of the Škoda Karoq's trunk opening is 6.7 in or 23% larger than that of the Volkswagen ID.3, and the loading edge of the VW ID.3 is 3.5 in or 13% higher above the ground than that of the Karoq.
All other figures (length with folded or upright rear seats, trunk depth difference of 0.4 in/7%, opening width +3.1 in/8%, narrowest width equal) are below the 10% mark and thus significantly smaller.
Impact on Usability
The significantly higher trunk opening of the Karoq makes loading tall or bulky items easier: bulky boxes, trolleys, or larger plants can be loaded and unloaded more easily through the larger cargo opening without hitting the headliner or tailgate.
Combined with the lower loading edge (since the ID.3's loading edge is 3.5 in higher), the Karoq also reduces the lifting height needed when loading heavy loads. For frequent lifting of heavy items, the Karoq is therefore more practical due to less lifting and better vertical clearance.
The higher loading edge of the ID.3 means more effort is required to lift heavy luggage or bulky loads – this is especially noticeable with regular loading or for older people.
Advantages of the ID.3 (smaller trunk depth, slightly longer load floor with upright first row of seats, or marginally longer floor with folded seats) exist but are minor and affect everyday usability much less than the two major differences in opening and loading edge height.
