The Polestar 3 has 17 cu ft of cargo space. In practice that is 2 checked suitcases, or 8 carry-ons, or about 13 supermarket bags. A folded pushchair fits.
What actually fits in a 3
Cubic feet are an abstraction — 17 cu ft means nothing until you load it. Here is the same number in things people actually load, 2 checked cases or 8 carry-ons for the Polestar 3, with a packing allowance — a boot is not a cube, and corners go to waste.
| What you are loading | How many fit | Each item |
|---|---|---|
| Checked suitcases | 2 | 27 × 21 × 14″ — 4.6 cu ft |
| Carry-on cases | 8 | 22 × 14 × 9″ — 1.6 cu ft |
| Supermarket bags | 13 | about 1 cu ft each |
| Golf bags | 2 | full set, about 5 cu ft |
| Folded pushchair | Fits | about 6 cu ft |
Counts assume 80% usable volume: luggage does not tessellate, and a wheel arch eats the rest.
Cars with the same room
Closest matches by load volume with the seats folded — useful when the boot is the deciding factor and the badge is not. The Polestar 3 sits at 17 cu ft, so these are the cars that carry the same load.
| Car | Load volume | vs Polestar 3 | Checked suitcases | Measured |
|---|---|---|---|---|
| Mini Clubman | 0 cu ft | 2 | 2011 | |
| Volkswagen e-Golf | 0 cu ft | 2 | 2019 | |
| Dodge Caliber | -1 cu ft | 2 | 2012 | |
| Kia Spectra | +1 cu ft | 3 | 2009 | |
| Volkswagen Beetle | -2 cu ft | 2 | 2019 | |
| Volvo C30 | -2 cu ft | 2 | 2013 |

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 — 2 checked cases for the Polestar 3 come out of its 17 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 Polestar 3 counts as 13.6 cu ft of usable space rather than 17. Suitcase sizes are the airline standards — 22 × 14 × 9″ for carry-on, 27 × 21 × 14″ for checked, so the Polestar 3 takes 8 of the small ones. Numbers are deliberately conservative; if we say four cases fit, four cases fit.
