Trunk comparison: Kia Sportage vs VW Touran

Key Differences (>10%)
In a direct comparison, four clearly relevant differences stand out: The VW Touran offers a cargo floor that is 4.3 in (12%) longer with the first row of seats upright than the Kia Sportage. Conversely, the Kia Sportage has a trunk that is 22 in (165%) larger with all seats upright compared to the Touran.
The height of the trunk opening of the VW Touran is 5.1 in (18%) greater, while the loading edge of the Kia Sportage is 3.9 in (16%) higher above the ground. All other differences are less than 10% and thus rather minor in everyday use.
Impact on Usability
The 22 in longer trunk length of the Sportage with all seats in place means that it can accommodate significantly more luggage or larger pieces of luggage behind the seats in daily use — advantageous for families or longer trips when all passengers are on board and luggage is still needed.
The 4.3 in longer cargo floor of the Touran with the first row upright makes it more flexible for longer items when certain seat configurations can be adjusted; it is thus somewhat better suited for carrying elongated cargo with variable seat usage.
The 5.1 in higher trunk opening of the Touran makes it easier to store tall or bulky items because more vertical space is available.
In contrast, the 3.9 in higher loading edge of the Sportage makes lifting heavy loads into the trunk more difficult and makes loading and unloading physically more demanding; however, the SUV-typical higher seating position makes getting in and out easier.
In summary: The Sportage offers significantly more usable storage space with full seat occupancy, while the Touran scores with a more practical opening height and a slightly larger cargo floor in certain seat configurations. Smaller differences in width, depth, and capacity are hardly noticeable in everyday life.
