Cargo Space and Storage Rating:
In spite of its wagon body style, the Panamera Sport Turismo is short on both cargo space and passenger-area storage cubbies.

Cargo Volume Comparisons
The Panamera Sport Turismo’s cargo bay is noticeably smaller than its competitors. A 40/20/40 split-folding rear seat expands the available space considerably, but the Porsche still falls short of its wagon rivals.
The Panamera Sport Turismo’s lift-over height is on the taller side of the class. That being said, the Porsche wagon’s rear lip is positioned more than half a foot lower than its fastback counterpart.

Interior Cubby Storage
Generous door pockets, a reasonably sized glovebox, and an awkwardly shaped center-console bin serve as the Panamera Sport Turismo’s main interior storage spaces. Storage space in the cargo hold is a rare feature in this class, and the Porsche’s underfloor well is noticeably larger than the small spaces offered in other similarly sized wagons.
Why do we use ping-pong balls?
To determine the interior space available to stash travel essentials, we’ve devised a range of measuring protocols. We use six beverage containers ranging in size and shape to gauge cupholder accommodation. We stack, stuff, and arrange 9-by-14-by-22-inch cardboard boxes to quantify the number of airline-carry-on-size suitcases that will fit in a trunk or folded seat’s cargo space. To measure irregularly shaped gloveboxes, door pockets, and console bins, we fill each container with 1.5-inch-diameter ping-pong balls. It’s tempting to convert the number of spheres to a volume (cubic inches), but we resist that calculation because-as with the box of tissues, 12-ounce can of soda, or gallon of milk you might stash in these compartments-there are voids between the balls. Random packing (our procedure) nullifies approximately one-third of the available space. The negative space between the balls could theoretically be reduced to 25 percent of an irregular shape with precise stacking, but while we might be pedantic, we’re not crazy.
