The Pontiac Wave has 7 cu ft of cargo space. In practice that is 1 checked suitcases, or 3 carry-ons, or about 5 supermarket bags. A folded pushchair will not fit alongside luggage. Against 245 cars with a similar-sized cabin it sits below the average of 15.1 cu ft.
What actually fits in a Wave
Cubic feet are an abstraction — 7 cu ft means nothing until you load it. Here is the same number in things people actually load, 1 checked cases or 3 carry-ons for the Pontiac Wave, 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 | 1 | 27 × 21 × 14″ — 4.6 cu ft |
| Carry-on cases | 3 | 22 × 14 × 9″ — 1.6 cu ft |
| Supermarket bags | 5 | about 1 cu ft each |
| Golf bags | 1 | full set, about 5 cu ft |
| Folded pushchair | Does not fit | 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 Pontiac Wave gives 7.1% of its 98 cu ft to luggage. The share below is the honest way to compare an estate with a coupé of the same footprint, and among 245 cars with a cabin within eight cubic feet of the Pontiac Wave the boot averages 15.1 cu ft.
| Space | Volume | Share of total |
|---|---|---|
| Passenger cabin | 91 cu ft | |
| Cargo area | 7 cu ft | |
| Total interior | 98 cu ft |
Under 15% to luggage — the space went to passengers, not their bags.
Against cars with a similar cabin
Compared with 245 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 | 7 cu ft | 15.1 cu ft | -8.1 cu ft |
| In checked suitcases | 1 | 2 | -1 |
Cars with the same room
Closest matches by trunk volume — useful when the boot is the deciding factor and the badge is not. The Pontiac Wave sits at 7 cu ft, so these are the cars that carry the same load.
| Car | Trunk volume | vs Pontiac Wave | Checked suitcases | Measured |
|---|---|---|---|---|
| Ferrari 456 MGT | 0 cu ft | 1 | 2003 | |
| Rolls-Royce Corniche | 0 cu ft | 1 | 2001 | |
| Fisker Karma | 0 cu ft | 1 | 2012 | |
| Bentley Azure | +1 cu ft | 1 | 2010 | |
| Mazda RX-8 | +1 cu ft | 1 | 2011 | |
| BMW 325Ci | +2 cu ft | 1 | 2006 |

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 — 1 checked cases for the Pontiac Wave come out of its 7 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 Pontiac Wave counts as 5.6 cu ft of usable space rather than 7. Suitcase sizes are the airline standards — 22 × 14 × 9″ for carry-on, 27 × 21 × 14″ for checked, so the Pontiac Wave takes 3 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 Pontiac Wave have?
7 cu ft behind the rear seats, plus 91 cu ft of passenger cabin.
How many suitcases fit in a Wave?
About 1 checked cases (27 × 21 × 14″) or 3 carry-ons, allowing for the fact that a boot is not a perfect cube.
Will a pushchair fit in a Wave?
Not comfortably. A folded pushchair needs about 6 cu ft and this car offers 7 in total, so it would fill the boot entirely.
Is that a lot for this size of car?
Compared with 245 cars of a similar cabin size, it is below the average of 15.1 cu ft.
