There are 109,065 of them on Dutch roads, built between 1991 and 2025, weighing anywhere from 630 to 1,505 kg. They share a name and not much else. Here is the spread.
Half of every Cooper on the road is below this. Power divided by mass in running order — the one figure that compares across model and era.
A typical Cooper has more power per tonne than 84% of the 8,248,168 combustion cars in the Netherlands.
For the median version, from power, mass and body shape. A prediction, not a measurement.
The slowest in this sample makes 47.6 kW per tonne and the quickest 139.8 — a factor of 2.9 between two cars wearing the same badge. Any single number for a Cooper is an average over that.

Asking the server…
Everything above describes 109,065 cars sharing a name, spanning 1991 to 2025 and 630–1,505 kg. Your Cooper has one engine, one mass and one registration. Put the plate in and the answer is about that car rather than about the name on it.
