There are 639 of them on Dutch roads, built between 1969 and 1984, weighing anywhere from 1,115 to 1,340 kg. They share a name and not much else. Here is the spread.
Half of every 99 on the road is below this. Power divided by mass in running order — the one figure that compares across model and era.
A typical 99 has more power per tonne than 49% 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 49.6 kW per tonne and the quickest 111.5 — a factor of 2.2 between two cars wearing the same badge. Any single number for a 99 is an average over that.

Everything above describes 639 cars sharing a name, spanning 1969 to 1984 and 1,115–1,340 kg. Your 99 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.
