Trunk comparison: Mazda Mazda CX-5 vs VW ID.3

Key Differences

The Mazda CX‑5 offers advantages in cargo volume primarily in length: with the seats folded down, its trunk is 6.7 in longer (≈11%) than the VW ID.3, and with the first row of seats upright, the lead is even 6.7 in (≈22%).

In contrast, the VW ID.3 has a significantly greater depth between the loading edge and the trunk floor: this is 4.3 in (≈220%) larger than in the CX‑5. Smaller differences concern the height of the opening (+1.6 in/5% in favor of the Mazda), the loading edge height (+0.4 in/1% in favor of the ID.3), as well as the widths (at the narrowest point +1.6 in/4% and opening width +3.9 in/10% in favor of the Mazda), which fall below the 10% threshold and therefore have less impact.

Impact on Usability

The longer interior dimensions of the Mazda CX‑5 make it more practical for long or elongated items: furniture boards, long sports equipment, or larger boxes can be transported more easily with folded down or even upright front seats.

The additional length dimension increases flexibility in everyday use because even when carrying passengers in the front seats, significantly more loading length is still available.

The much greater depth value of the VW ID.3 means that cargo can be stored further "down" or deeper in the trunk — this provides more usable volume for bulky or stackable items that fit in depth.

Practically, this means: bulky but not very long cargo can be stored more compactly in the ID.3. However, the deeper loading floor can make loading heavy items more difficult because they have to be lifted further "inward," and it can make removing irregularly shaped cargo somewhat more cumbersome.

In practice, this results in a clear usage division: those who frequently transport long, flat items or often work with variable loading length benefit from the Mazda CX‑5. Those who rely more on bulky loads that can be stored in depth are better off with the VW ID.3. Smaller advantages in opening and width dimensions also slightly favor the Mazda for easier maneuvering of wider items in and out.
