Audi Q3 Cargo Space — 17 cu ft and What Fits

Quick answer

The Audi Q3 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. Against 67 cars with a similar-sized cabin it sits above the average of 15.7 cu ft.

What actually fits in a Q3

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 Audi Q3, 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

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 Audi Q3 gives 16.8% of its 101 cu ft to luggage. The share below is the honest way to compare an estate with a coupé of the same footprint, and among 67 cars with a cabin within eight cubic feet of the Audi Q3 the boot averages 15.7 cu ft.

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

Against cars with a similar cabin

Compared with 67 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 load volume with the seats folded — useful when the boot is the deciding factor and the badge is not. The Audi Q3 sits at 17 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 — 2 checked cases for the Audi Q3 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 Audi Q3 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 Audi Q3 takes 8 of the small ones. Numbers are deliberately conservative; if we say four cases fit, four cases fit.

17 cu ft behind the rear seats, plus 84 cu ft of passenger cabin.

How many suitcases fit in a Q3?

About 2 checked cases (27 × 21 × 14″) or 8 carry-ons, allowing for the fact that a boot is not a perfect cube.

Will a pushchair fit in a Q3?

Yes — a folded pushchair takes roughly 6 cu ft and this car has 17, so it fits with room for shopping.

Compared with 67 cars of a similar cabin size, it is above the average of 15.7 cu ft.
