L300

Saturn L300 Trunk Space

The Saturn L300 holds 18 cu ft — that is 3 checked suitcases or 9 carry-ons, with the boot loaded properly rather than to the brim.

Quick answer

The Saturn L300 has 18 cu ft of cargo space. In practice that is 3 checked suitcases, or 9 carry-ons, or about 14 supermarket bags. A folded pushchair fits. Against 300 cars with a similar-sized cabin it sits above the average of 16.9 cu ft.

What actually fits in a L300

Cubic feet are an abstraction — 18 cu ft means nothing until you load it. Here is the same number in things people actually load, 3 checked cases or 9 carry-ons for the Saturn L300, 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 Saturn L300 gives 15.7% of its 115 cu ft to luggage. The share below is the honest way to compare an estate with a coupé of the same footprint, and among 300 cars with a cabin within eight cubic feet of the Saturn L300 the boot averages 16.9 cu ft.

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

Against cars with a similar cabin

Compared with 300 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 Saturn L300 sits at 18 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 Saturn L300 come out of its 18 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 Saturn L300 counts as 14.4 cu ft of usable space rather than 18. Suitcase sizes are the airline standards — 22 × 14 × 9″ for carry-on, 27 × 21 × 14″ for checked, so the Saturn L300 takes 9 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 Saturn L300 have?

18 cu ft behind the rear seats, plus 97 cu ft of passenger cabin.

How many suitcases fit in a L300?

About 3 checked cases (27 × 21 × 14″) or 9 carry-ons, allowing for the fact that a boot is not a perfect cube.

Will a pushchair fit in a L300?

Yes — a folded pushchair takes roughly 6 cu ft and this car has 18, so it fits with room for shopping.

Is that a lot for this size of car?

Compared with 300 cars of a similar cabin size, it is above the average of 16.9 cu ft.
