XB

Scion xB Trunk Space

The Scion xB holds 22 cu ft — that is 3 checked suitcases or 11 carry-ons, with the boot loaded properly rather than to the brim.

Quick answer

The Scion xB has 22 cu ft of cargo space. In practice that is 3 checked suitcases, or 11 carry-ons, or about 17 supermarket bags. A folded pushchair fits. Against 273 cars with a similar-sized cabin it sits above the average of 17.4 cu ft.

What actually fits in a xB

Cubic feet are an abstraction — 22 cu ft means nothing until you load it. Here is the same number in things people actually load, 3 checked cases or 11 carry-ons for the Scion xB, with a packing allowance — a boot is not a cube, and corners go to waste.

Counts assume 80% usable volume: luggage does not tessellate, and a wheel arch eats the rest.

Cabin or boot — where the space went

Every car is a fixed envelope, and designers decide how to split it between people and things — the Scion xB gives 17.9% of its 123 cu ft to luggage. The share below is the honest way to compare an estate with a coupé of the same footprint, and among 273 cars with a cabin within eight cubic feet of the Scion xB the boot averages 17.4 cu ft.

A typical split for a family car: room for people first, luggage second.

Against cars with a similar cabin

Compared with 273 models whose passenger space is within eight cubic feet — a fairer group than marketing classes, which put an estate and a coupé in the same bracket.

Cars with the same room

Closest matches by trunk volume — useful when the boot is the deciding factor and the badge is not. The Scion xB sits at 22 cu ft, so these are the cars that carry the same load.

How we count

Cargo and passenger volumes come from EPA interior-volume records — the same figures manufacturers file for the window sticker, measured to a standard method rather than claimed in a brochure.

The luggage counts are ours — 3 checked cases for the Scion xB come out of its 22 cu ft. We assume 80% usable volume, because a boot is not a cube: wheel arches, a sloping tailgate and the shape of the cases themselves waste the rest, which is why the Scion xB counts as 17.6 cu ft of usable space rather than 22. Suitcase sizes are the airline standards — 22 × 14 × 9″ for carry-on, 27 × 21 × 14″ for checked, so the Scion xB takes 11 of the small ones. Numbers are deliberately conservative; if we say four cases fit, four cases fit.

Frequently asked questions

How much cargo space does the Scion xB have?

22 cu ft behind the rear seats, plus 101 cu ft of passenger cabin.

How many suitcases fit in a xB?

About 3 checked cases (27 × 21 × 14″) or 11 carry-ons, allowing for the fact that a boot is not a perfect cube.

Will a pushchair fit in a xB?

Yes — a folded pushchair takes roughly 6 cu ft and this car has 22, so it fits with room for shopping.

Is that a lot for this size of car?

Compared with 273 cars of a similar cabin size, it is above the average of 17.4 cu ft.
