Trunk comparison: Mazda Mazda CX-5 vs VW Caddy Wagon

Key Dimensions and Practical Implications
The cargo volume reveals distinctly different usage patterns: The Mazda CX‑5 offers +21.3 in (47%) more cargo length with the seats folded down than the VW Caddy Wagon, making it clearly the better choice for long items.
However, with the front seats upright, the VW Caddy Wagon has +4.3 in (11%) more usable trunk length, which is an advantage in everyday use with passengers in the rear seats.
When it comes to loading comfort, the Caddy is clearly ahead: The trunk opening is +13.8 in (44%) higher than in the CX‑5, making it easier to load bulky or tall items with less tilting motion.
The slightly greater width at the narrowest point (+3.1 in, 8%) and the somewhat wider opening (+2.8 in, 7%) are noticeable but below the 10% mark and thus only marginal advantages for the Caddy.
The Mazda has a deeper loading floor from the edge of the trunk lip to the trunk floor: +1.2 in (150%) compared to the Caddy. Practically, this means that cargo sits a bit lower in the CX‑5, which improves the stability of heavy items and makes better use of the interior space.
On the other hand, the CX‑5’s trunk lip height is +7.5 in (33%) higher above the road than the Caddy’s, making lifting heavy loads into the CX‑5 more strenuous.
What This Means in Practice
For users who frequently transport long items (e.g., furniture, roof rack parts, long sports equipment) and fold down the rear seats, the Mazda CX‑5 is better suited: it offers significantly more cargo length and a deeper loading floor for more stable cargo placement.
Those who regularly travel with passengers and simultaneously need to transport bulky, tall, or wider items will benefit more from the VW Caddy Wagon: the higher opening and slightly greater width make loading easier and increase versatility in daily use.
For frequent lifting of heavy loads, the Caddy is also more practical due to the lower trunk lip.
