Trunk comparison: Kia Stonic vs Toyota Corolla Wagon
Key Differences
The Toyota Corolla Touring Sports offers significantly more cargo length: with the seats folded down, the trunk is +19.3 in (36%) longer, and with the front seats upright, even +13 in (48%) longer compared to the Kia Stonic.
On the other hand, several dimensions are larger in the Kia Stonic: the depth of the trunk (loading edge to trunk floor) is +3.9 in (125%) higher, the loading edge is +5.1 in (20%) higher above the ground, and the width at the narrowest point is +3.9 in (11%) greater than in the Corolla.
Smaller differences under 10% include: the trunk opening of the Kia is 1.6 in (5%) higher and the width of the Corolla's trunk opening is 1.6 in (4%) larger.
Impact on Usability
Due to the significantly greater cargo length in the Corolla Touring Sports, long items (e.g., skis, long boxes, furniture parts) and more luggage can be transported more easily and flatly, especially when the rear seats are folded down.
For users who regularly load long or many bulky items, the Corolla offers a noticeable advantage.
The Kia Stonic, on the other hand, scores with a greater usable width at the narrowest point, which facilitates loading wider items crosswise.
The significantly greater depth of the cargo area in the Stonic (loading edge to floor) creates a deeper trunk where small or loose items stay more secure and can be better stored under covers; at the same time, this depth can hinder storing tall or bulky loads because more volume lies below the loading edge.
The +5.1 in higher loading edge in the Stonic also means that heavy cargo must be lifted higher — making daily loading and unloading more difficult.
In summary: Those who value maximum length and a flat cargo area (long items, many suitcases) benefit from the Corolla Touring Sports.
Those who more often load wide items crosswise, value a deeper cargo area, and a more compact overall design will find advantages in the Kia Stonic — but must accept a higher loading edge and a deeper loading floor.
