Saturn Cargo Space by Model — Measured Trunk & Load Volume

Quick answer

Saturn models average 15.8 cu ft of boot — roughly 2 checked suitcases. The roomiest holds 25 cu ft, the tightest 9, across 8 measurements.

What actually fits

A translation from cubic feet into luggage, on Saturn's own models, so the numbers below mean something.

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 — computed for all 9 Saturn models below. 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, so the 15.8 cu ft Saturn averages becomes 12.6 cu ft you can actually pack. Suitcase sizes are the airline standards — 22 × 14 × 9″ for carry-on, 27 × 21 × 14″ for checked, and the roomiest Saturn here swallows 4 checked cases. Numbers are deliberately conservative; if we say four cases fit, four cases fit.
