Trunk comparison: Tesla Model Y vs VW ID.4

Key Differences

In terms of space, there is a clear length/height contrast: The Tesla Model Y offers a longer cargo area with folded seats by +9.8 in (15%) and with the first row upright by +6.7 in (18%) compared to the VW ID.4. Conversely, the VW ID.4 has a higher trunk opening by +4.3 in (16%) and a significantly deeper cargo well (loading edge to trunk floor) by +3.9 in (900%) compared to the Tesla.

Impact on Usability

The longer cargo space of the Model Y makes it more practical for long, flat items like boards, skis, long boxes, or flat-packed furniture parts — less folding down or rearranging is needed to accommodate such objects.

The ID.4 scores better with tall and bulky loads: the larger opening height makes it easier to load tall items, and the deeper cargo well creates more effective interior volume and allows safe stacking without the trunk lid hitting the load.

Practical consequences: Those who often transport long items (e.g., craftsmen, sports equipment like surfboards/skis) have the advantage with the Model Y.

Those who frequently carry taller, bulky, or stacked goods (e.g., boxes, plants, luggage on trips) benefit more from the ID.4. Smaller differences — the loading edge of the ID.4 is only +1.6 in (6%) higher and the width differences are each +2.4 in (6%) in favor of the ID.4 — are hardly decisive in everyday use: the slightly higher loading edge makes lifting only marginally more strenuous, the slightly greater width offers moderately more room when loading.

In summary: Model Y = advantage in length/linear loads; ID.4 = advantage in height, depth, and volume for bulky or stacked cargo.
