The Aston Martin DBX has 29 cu ft of cargo space. In practice that is 5 checked suitcases, or 14 carry-ons, or about 23 supermarket bags. A folded pushchair fits. Against 32 cars with a similar-sized cabin it sits above the average of 25.2 cu ft.
What actually fits in a DBX
Cubic feet are an abstraction — 29 cu ft means nothing until you load it. Here is the same number in things people actually load, 5 checked cases or 14 carry-ons for the Aston Martin DBX, 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 | 5 | 27 × 21 × 14″ — 4.6 cu ft |
| Carry-on cases | 14 | 22 × 14 × 9″ — 1.6 cu ft |
| Supermarket bags | 23 | about 1 cu ft each |
| Golf bags | 4 | 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.
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 Aston Martin DBX gives 21.6% of its 134 cu ft to luggage. The share below is the honest way to compare an estate with a coupé of the same footprint, and among 32 cars with a cabin within eight cubic feet of the Aston Martin DBX the boot averages 25.2 cu ft.
| Space | Volume | Share of total |
|---|---|---|
| Passenger cabin | 105 cu ft | |
| Cargo area | 29 cu ft | |
| Total interior | 134 cu ft |
A typical split for a family car: room for people first, luggage second.
Against cars with a similar cabin
Compared with 32 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.
| Measure | This car | Similar cars | Difference |
|---|---|---|---|
| Cargo volume | 29 cu ft | 25.2 cu ft | +3.8 cu ft |
| In checked suitcases | 5 | 4 | +1 |
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 Aston Martin DBX sits at 29 cu ft, so these are the cars that carry the same load.
| Car | Load volume | vs Aston Martin DBX | Checked suitcases | Measured |

| Hyundai Ioniq | -2 cu ft | 4 | 2022 | |
| Porsche Panamera | -2 cu ft | 4 | 2026 | |
| BMW X1 | -2 cu ft | 4 | 2022 | |

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 — 5 checked cases for the Aston Martin DBX come out of its 29 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 Aston Martin DBX counts as 23.2 cu ft of usable space rather than 29. Suitcase sizes are the airline standards — 22 × 14 × 9″ for carry-on, 27 × 21 × 14″ for checked, so the Aston Martin DBX takes 14 of the small ones. Numbers are deliberately conservative; if we say four cases fit, four cases fit.

Yes — a folded pushchair takes roughly 6 cu ft and this car has 29, so it fits with room for shopping.
Is that a lot for this size of car?
Compared with 32 cars of a similar cabin size, it is above the average of 25.2 cu ft.
